Description

Technical Field

[0001] This utility model relates to the field of floor height detection technology in the refrigeration industry, and in particular to an intelligent floor height detection device in the refrigeration industry. Background Technology

[0002] In the refrigeration industry, when manufacturing air conditioners, the process of inserting copper tubes into the fin assembly is required to prepare the condenser. First, the copper tubes to be inserted are transported to the processing position. Then, the copper tubes are transported to the assembly position and inserted into the fins through a transport mechanism and an insertion mechanism. The number of layers of copper tubes to be inserted needs to be checked to avoid the problem that the number of copper tubes inserted into the fins is less than the required set number, which would result in the number of copper tubes inserted into the fins being lower than the production requirements.

[0003] Currently, the height of the copper tube layer needs to be determined manually, which is inaccurate and inefficient. It is also difficult to guarantee the number of copper tubes inserted, thus making it difficult to ensure the production quality of the condenser. Utility Model Content

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] like Figure 1-2 The image shows an intelligent height detection device for the refrigeration field provided in this embodiment, including a copper tube lifting and feeding mechanism 1 and a copper tube removal mechanism 2 located on the upper side of the copper tube lifting and feeding mechanism;

[0058] The copper tube lifting and feeding mechanism includes a bracket for supporting the copper tube taking out mechanism 2, a loading unit 11 for driving the loading platform 111 carrying the copper tube to be inserted to move to the lower side of the copper tube taking out mechanism, and a copper tube lifting unit 12 provided on the bracket for driving the loading platform to rise to approach the copper tube taking out mechanism 2 and obtaining the rising stroke of the loading platform.

[0059] The copper tube removal mechanism 2 includes a lifting unit 21, a translation unit 22, a clamping unit 23, a floor height detection unit 24, and a mounting frame 25. The mounting frame 25 is mounted on the bracket, the translation unit 22 is mounted on the mounting frame and can move laterally on the mounting frame, the lifting unit 21 is mounted on the translation unit 22, the floor height detection unit 24 and the clamping unit 23 are mounted on the lifting unit 21, the clamping unit is located on both sides of the floor height detection unit, the lifting unit can drive the floor height detection unit and the clamping unit to descend towards the copper tube 3 on the loading platform and reach a set position, the floor height detection unit can detect the copper tube that has risen to the set position and send the detection signal to the controller, and the clamping unit 23 can clamp both ends of the copper tube that has risen to the set position.

[0060] The copper tube lifting unit 12 can send the lifting stroke of the loading platform from the initial position to the controller when the top copper tube on the loading platform is raised to the set position.

[0061] If the number of layers (layer height) of copper tubes with insertions stacked from bottom to top on the loading platform meets the actual production requirements, when the lifting unit 21 and translation unit 22 drive the layer height detection unit 24 to the set position on the upper side of the copper tube lifting and loading mechanism 1, the layer height detection unit 24 can detect the copper tubes on the loading platform when it is in the initial position and send the detection signal to the controller. At the same time, the clamping unit 23 clamps the top layer of copper tubes on the loading platform, and then drives the clamped copper tubes to the next copper tube insertion process station through the lifting unit 21 and translation unit 22. If the number of layers (layer height) of copper tubes with insertions stacked on the loading platform does not meet the actual production requirements, after the layer height detection unit 24 is driven to the set position by the lifting unit 21, the layer height detection unit 24 cannot detect the copper tubes on the loading platform. A signal will be detected and sent to the controller. Then, the copper tube lifting unit 12 will drive the copper tubes on the loading platform to rise along the support. After the layer height detection unit 24 detects the signal, the copper tube lifting unit 12 will send the rising stroke of the loading platform from the initial position to the top copper tube on the loading platform when it rises to the set position to the controller. Based on the rising stroke, and combined with the known total copper tube layer height and the diameter (layer height) of each copper tube in the actual production setting, the controller can calculate the total number of copper tube layers on the loading platform, and thus obtain the layer height of the copper tubes (the calculation formula is: known total copper tube layer height in the actual production setting - (rising stroke ÷ known layer height of each copper tube)). The controller is existing technology, and its process and principle of receiving signals and data and calculating the total number of copper tube layers will not be described here.

[0062] This utility model discloses an intelligent layer height detection device for the refrigeration field. By setting up a copper tube lifting unit and a loading unit in the copper tube lifting and feeding mechanism, and a lifting unit and a layer height detection unit in the copper tube removal mechanism, it can detect the total layer height of the copper tubes to be inserted into the fins, thereby ensuring the number of inserted copper tubes. This device avoids manual detection of the copper tube layer height, automates the detection of the copper tube layer height, and provides accurate and efficient results. The number of inserted copper tubes can be guaranteed, thus ensuring the quality of the condenser.

[0063] In a specific embodiment, such as Figure 7-11 As shown, the floor height detection unit 24 includes a fixed sleeve 241, a connecting rod 242, a spring 243, a contact plate 244, a sensor 245, and a detection plate 246;

[0064] The fixed sleeve 241 is fixed on the connecting frame provided on the lifting unit 21. The connecting rod 242 is vertically arranged and slidably arranged inside the fixed sleeve 241. The bottom of the connecting rod 242 extends out of the fixed sleeve 241 and is connected to the contact plate 244 arranged in the horizontal direction. The top of the connecting rod 242 extends out of the fixed sleeve 241 and is connected to the detection plate 246. The spring 243 is sleeved on the outside of the bottom of the connecting rod 242. The top of the spring 243 abuts against the bottom of the fixed sleeve 241, and the bottom abuts against the top surface of the contact plate 244.

[0065] The sensor 245 is mounted on the connecting frame 26.

[0066] The translation unit drives the lifting unit and connecting frame to move the contact plate 244 of the layer height detection unit above the copper tubes on the loading platform 111. If the number of copper tube layers on the loading platform 111 is the number of layers (layer height) required to meet actual production needs, the lifting unit drives the layer height detection unit to descend to the set position. First, the bottom surface of the contact plate 244 abuts against the uppermost copper tube on the loading platform. As the lifting unit continues to drive the fixed sleeve 241 on the connecting frame to move downward, the spring 243 is compressed. When the spring 243 is compressed to its maximum extent, the lifting unit continues to drive the fixed sleeve 241, spring 243, and contact plate 244 to move downward. Due to the copper tubes on the loading platform... The copper tube is always in contact with the bottom of the contact plate 244. The copper tube and the contact plate 244 will exert an upward force on the connecting rod 242 in the fixing sleeve 241, thereby driving the connecting rod 242 and the detection plate 246 at the top of the connecting rod 242 to move upward toward the sensor 245 on the connecting frame. When the detection plate 246 moves upward to enter the detection area of ​​the sensor 245, the sensor 245 receives the detection signal. At this time, the floor height detection unit has descended to the set position (i.e., the position where the uppermost copper tube of the copper tube with the required fixed floor height can be clamped). Then the clamping unit clamps the two ends of the copper tube. Finally, the lifting unit and the translation unit drive the copper tube into the next process (inserting copper tube) operation station.

[0067] When the contact plate 244 of the layer height detection unit is driven to the set position by the lifting unit, the bottom of the contact plate 244 does not contact the uppermost copper tube of the loading platform, and the detection plate 246 does not enter the detection area of ​​the sensor 245. At this time, the number of copper tube layers (layer height) of the loading platform does not meet the actual production requirements. Then, the copper tube lifting unit 12 drives the loading platform and the copper tubes on it to move upward toward the contact plate 244 near the copper tube removal mechanism. After the bottom surface of the contact plate 244 contacts the uppermost copper tube of the loading platform, the loading platform and the copper tubes on it continue to be driven upward. The movement drives the detection plate 246 upward, compressing the spring 243. When the spring 243 is compressed to its maximum extent, the upward movement of the loading platform and copper tube generates an upward driving force on the connecting rod 242 inside the fixed sleeve 241. This drives the connecting rod 242 and the detection plate 246 at the top of the connecting rod 242 upward. When the detection plate 246 moves upward and enters the detection area of ​​the sensor 245, the sensor 245 detects the signal from the top copper tube on the loading platform and sends the signal to the controller (the controller is existing technology). Then, the clamping unit clamps the copper tube. The lifting unit drives the connecting frame, the layer height detection unit, and the clamping unit. The copper tube lifting and translating unit moves the copper tube laterally on the mounting frame to the next processing station. The controller, based on the lifting unit 12's rise from the initial position to the set position of the top layer of copper tubes on the loading platform, and combined with the known total copper tube layer height and the diameter (layer height) of each layer of copper tubes in actual production, can calculate the initial layer height of the copper tubes on the loading platform, thus realizing the detection of the copper tube layer height. For example, if the height of each layer of copper tubes on the loading platform is known to be 1cm, the actual layer height can be calculated. The actual production requirement is that the total height of the 40-layer copper tubes is 40cm. In the actual testing process, the upward stroke of the loading platform from the initial position to the top copper tube on the loading platform when it rises to the set position is 1cm. That is, after the copper tube moves upward by 1cm (the upward stroke of the loading platform from the initial position to the top copper tube on the loading platform when it rises to the set position is obtained by the drive device of the copper tube lifting unit with readable stroke), the sensor 245 detects the signal of the top copper tube for the first time, which indicates that the current number of copper tube layers is 39 and the layer height is 39cm.

[0068] In a specific embodiment, the copper tube lifting unit 12 includes a lifting fork 121, a mounting bracket 122, a lifting drive device 123, and a lifting guide assembly 124;

[0069] The mounting bracket 122 is fixed on the bracket. The lifting fork 121 is arranged horizontally and can be slidably mounted on the mounting bracket 122 in the vertical direction through the lifting guide assembly 124. The lifting drive device 123 is disposed on the mounting bracket 122 and fixedly connected to the lifting fork 121. The loading platform of the loading unit can move to the upper side of the lifting fork 121. The lifting drive device 123 can drive the lifting fork 121 to rise along the lifting guide assembly 124. The lifting fork 121 drives the loading platform and the copper pipe on it above it to rise on the mounting bracket 122.

[0070] Specifically, the lifting guide assembly 124 includes a lifting guide rail and a lifting slider; the lifting guide rail is vertically mounted on both sides of the mounting bracket 122, and the lifting fork 121 is mounted on the lifting guide rail via the lifting slider;

[0071] The lifting drive device 123 includes a lifting servo motor, a lifting screw, and a lifting nut. The lifting motor is mounted on the mounting bracket 122 and connected to the lifting screw. The lifting nut is located on the lifting screw and is fixedly connected to the lifting fork 121.

[0072] When the copper tube lifting unit drives the loading platform and the copper tubes on it to approach the copper tube removal mechanism, the loading platform is first manually moved to the upper side of the lifting fork 121. Then, the lifting servo motor drives the lifting nut on the lifting screw to rise through the lifting screw. The lifting nut drives the lifting fork 121 to rise along the lifting guide rail. The lifting fork 121 drives the loading platform and the copper tubes on it to rise along the lifting guide rail and approach the contact plate of the layer height detection unit of the copper tube removal mechanism. The copper tube lifting unit and the layer height detection unit cooperate to detect the layer height of the copper tubes. After all the copper tubes on the loading platform are clamped by the copper tube removal mechanism 2 and transported to the next station, the lifting drive device 123 drives the loading platform to descend to the initial position along the lifting guide assembly on the mounting bracket.

[0073] In a specific embodiment, the clamping unit 23 includes a drive plate 231, a plurality of rotating components 232, a clamping drive device 234, a drive plate guide component 235, and a plurality of clamping posts 236 spaced apart.

[0074] The drive plate guide assembly 235 is disposed on the upper surface of the contact plate 244. The bottom surface of the horizontally disposed drive plate 231 is connected to the drive plate guide assembly 235. The top of the clamping column 236 is connected to the bottom surface of the drive plate 231 through the rotating assembly 232. The bottom of the clamping column 236 extends out of the contact plate 244 through the through hole. The clamping drive device 234 is disposed on the contact plate 244 and can drive the drive plate 231 to move laterally along the drive plate guide assembly 235. The drive plate 231 can drive the clamping column 236 and the clamping blocks 237 disposed opposite on the outer peripheral wall of the clamping column 236 to rotate around the central axis of the clamping column 236 by driving the rotating assembly 232 to rotate, so that the adjacent clamping columns 236 clamp the copper tube driven to the adjacent clamping columns 236 by the copper tube lifting unit.

[0075] Specifically, the drive plate guide assembly 235 includes a drive plate guide rail and a drive plate slider. The drive plate guide rail is disposed on the upper surface of the contact plate 244, and the bottom of the drive plate 231 is mounted on the drive plate guide rail through the drive plate slider.

[0076] The clamping drive device 234 includes a drive cylinder 234a and a connecting plate 234b. The drive cylinder is mounted on the contact plate 244, and the piston end of the drive cylinder is connected to the connecting plate. The two ends of the connecting plate are respectively connected to the two drive plates 231 of a set of clamping units 23.

[0077] The bottom of the contact plate 244 is provided with several spaced guide partitions 247. When the contact plate comes into contact with the copper pipe, each guide partition is located between two adjacent copper pipe segments. During the process from the contact plate approaching the copper pipe to the contact plate coming into contact with the copper pipe, the guide partition plays a role in guiding the copper pipe segments and preventing the copper pipe segments from being misaligned.

[0078] In a specific embodiment, the rotating assembly 232 includes a driving block 232a and a follower shaft 232b. The driving block 232a is arranged horizontally, and a cam track groove is provided at one end of the upper surface of the driving block 232a. The top of the follower shaft 232b is fixed on the driving plate 231, and a cam is rotatably mounted at the bottom of the follower shaft 232b. The cam is located in the cam track groove and can move in the cam track groove under the drive of the driving plate 231. The top of the clamping column is fixedly connected to the lower side of the driving block 232a and away from the end with the cam track groove.

[0079] When the contact plate 244 of the floor height detection unit 24 moves to the set position and the sensor 245 detects the copper pipe signal, the clamping unit 23 starts to work. The specific process of the clamping unit 23 is as follows: the drive cylinder 234a drives the drive plate 231 to move laterally along the drive plate guide rail through the connecting plate 234b. The drive plate 231 drives the rotating shaft 232b to move. The rotating shaft 232b drives the cam to move in the cam track groove of the drive block 232a (along the cam track groove wall) and drives the drive block 232a to rotate. Then the drive block 232a drives the clamping column to rotate around the clamping column axis in the through hole on the contact plate 244, so that the clamping block 237 on the outer wall of the clamping column 236 rotates laterally to the radial direction of the copper pipe section. The two sides of a section of a copper pipe are clamped by the clamping blocks 237 on the clamping columns 236 on both sides.

[0080] In a specific embodiment, the copper tube removal mechanism 2 further includes a clamping detection unit 27 disposed on the contact plate 244. The clamping detection unit 27 includes an optical fiber sensor group 271, a floating pin fixing plate 272, a plurality of floating pins 273, a plurality of stops 274, and a plurality of support plates 275.

[0081] A plurality of floating pin fixing plates 272 are spaced apart on the contact plate 244. The floating pin is movably mounted on the floating pin fixing plates 272. The bottom of the floating pin 273 is movably mounted in the floating pin groove provided on the contact plate 244 and can extend out of the floating pin groove. A horizontally arranged stop block 274 is fixed in the middle of the floating pin 273 and on the upper side of the contact plate 244. A plurality of support plates are spaced apart on the upper surface of the contact plate 244 and are arranged between adjacent floating pins 273. The stop block 274 can rise with the floating pin 273 and rotate with the floating pin and be placed on the support plate 275, so that the bottom of the floating pin 273 completely enters the floating pin groove.

[0082] The two fiber optic sensors of the fiber optic sensor group 271 are respectively disposed on both sides of the contact plate 244 along the setting direction of the plurality of clamping posts 236; when the clamping unit 23 clamps the copper tube, the position of the stop block 274 is higher than the height of the fiber optic sensor light source.

[0083] When the bottom surface of the contact plate 244 abuts against the copper tube and the clamping unit clamps the copper tube, the copper tube abuts against the bottom of the floating pin. The copper tube drives the floating pin into the floating pin groove, and the stop block on the floating pin is driven to rise, so that the position of the stop block is higher than the position of the optical fiber sensor's transmitting head. After all the floating pins are lifted from the bottom by the copper tube and enter the floating pin groove, all the stop blocks are also driven to rise. The optical fiber sensor can then detect a signal, indicating that each copper tube in the layer has been clamped. If the optical fiber sensor does not detect a signal, it indicates that there are copper tubes in the layer that have not been clamped. Through the cooperation of the optical fiber sensor, the floating pin, and the stop block, it is possible to detect whether there are copper tubes to be inserted that have not been clamped, thereby detecting whether there are problems with missing or insufficient copper tubes in the fins, thus ensuring the production quality of the condenser.

[0084] When a copper tube does not need to be inserted at a certain position of the condenser fins, the floating pin at that position can be manually pulled up and rotated to place one end of the stop on the floating pin on the support plate on one side of the floating pin, so that the height of the stop on the floating pin is higher than the height of the fiber optic sensor light source. Even when no copper tube is clamped at this position, the fiber optic sensor can still detect the signal, allowing this device to adjust the number and position of copper tubes to be inserted in a layer, thereby meeting actual processing requirements and making it more applicable and flexible.

[0085] In a specific embodiment, such as Figure 3-5 As shown, the material loading unit includes a mobile vehicle 112, a feeding pusher plate 113, a first guide rod group 114, a second guide rod group 115, a pusher plate sliding assembly 116, and the feeding platform 111.

[0086] The loading platform is mounted on the moving vehicle 112. The loading push plate 113 is mounted on the moving vehicle 112 via the push plate sliding assembly 116 and is located on one side of the loading platform. The first guide rod group 114 is located on the loading push plate 113, and the second guide rod group 115 is located on the loading platform. One end of the copper tube is placed on the loading push plate 113, and the other end of the copper tube is placed on the loading platform. Each guide rod of the first guide rod group 114 and the second guide rod group 115 is sequentially located between adjacent copper tube sections. External force drives the loading push plate 113 to drive the copper tube to move towards the loading platform, so that the copper tube is placed at the copper tube removal position below the copper tube removal mechanism.

[0087] The pusher sliding assembly 116 includes a pusher slide rail mounted on the moving carriage 112 and a pusher slider fixed to the bottom of the feeding pusher 113. The pusher slide rail extends along the direction from the initial position of the copper tube to the removal position. The feeding pusher 113 is mounted on the pusher slide rail via the pusher slider. Initially, the copper tube is positioned on the moving carriage 112 away from the copper tube removal mechanism. At this time, the feeding pusher 113 is also positioned on the pusher slide rail away from the copper tube removal mechanism. The U-shaped head end of the copper tube to be inserted is always placed on the feeding pusher 113, and the tail end of the copper tube is always placed on the feeding platform. The first guide rod group 114 and the second guide rod group 11... Each guide rod of 5 is located between adjacent copper tube sections, and plays a guiding and limiting role in driving the copper tube movement. During processing, the feeding push plate 113 needs to be driven by external force to move along the push plate slide rail towards the copper tube removal mechanism. Due to gravity, several layers of copper tubes to be inserted are pushed onto the feeding platform by the feeding push plate 113 from bottom to top (the U-shaped head of the copper tube is always placed on the feeding push plate 113), and the copper tube is driven into the lower side of the copper tube removal mechanism. The clamping unit clamps the copper tube, and the copper tube lifting unit 12, together with the clamping unit 23, lifting unit 21, and translation unit 22, drives the copper tube to the next processing station.

[0088] In a specific embodiment, the lifting unit 21 includes a lifting plate 211, a lifting guide rail 212, a lifting slider, and a lifting drive cylinder 213. The vertically arranged lifting plate 211 is connected to the translation unit, the lifting guide rail 212 is vertically arranged on the lifting plate 211, the connecting frame 26 is installed on the lifting guide rail 212 through the lifting slider, the lifting drive cylinder is installed on the lifting plate, and the piston end of the lifting drive cylinder is connected to the connecting frame 26.

[0089] The connecting frame 26 is provided with a limiting plate 214, which is arranged horizontally. The upper part of the buffer 215 is provided on the connecting frame 26, and the bottom of the buffer 215 is connected to one end of the limiting plate. The other end of the limiting plate is provided in the limiting groove provided at the bottom of the lifting plate 211.

[0090] When the copper tube extraction mechanism 2 needs to clamp the copper tube to be inserted, the lifting drive cylinder drives the connecting frame and the connected layer height detection unit and the clamping unit on the layer height detection unit to descend along the lifting guide rail to the set height. Then, the layer height detection unit detects the height of the copper tube to be inserted on the loading platform. Then, the clamping unit cooperates with the copper tube lifting unit of the copper tube lifting loading mechanism to clamp (clamp) the copper tube to be inserted. After the clamping unit of the copper tube extraction mechanism clamps the layer of copper tubes to be inserted, the lifting drive cylinder drives the connecting frame and the connected layer height detection unit and the clamping unit on the layer height detection unit to rise along the lifting guide rail, so that the copper tube clamped by the clamping unit rises to a suitable height. Then, the translation unit drives it to the next copper tube insertion process station.

[0091] When the lifting drive cylinder drives the connecting frame to rise, the connecting frame can move to the position where the upper surface of the limiting plate on the connecting frame abuts against the top surface of the limiting groove of the lifting plate. The limiting groove and the limiting plate cooperate to limit the rising position of the connecting frame and limit the rising height of the copper tube. The buffer provides a buffering effect between the connecting frame and the lifting plate in this process, preventing excessive collision between the limiting plate and the lifting plate after they come into contact, which would cause damage to the plate.

[0092] In a specific embodiment, the translation unit 22 includes a translation guide rail 221, a translation slider 222, and a translation drive device 223;

[0093] The translation guide rail 221 is arranged horizontally on the mounting frame 25, the lifting plate 211 is mounted on the translation guide rail by a translation slider, and the translation drive device is arranged on the mounting frame and connected to the translation slider;

[0094] Specifically, the translation drive device includes a translation drive motor, a translation lead screw, and a translation nut. The translation drive motor is mounted on the mounting frame 25, the translation lead screw is connected to the translation drive motor, and the translation nut is mounted on the translation lead screw and fixedly connected to the translation slider. The translation drive motor drives the lifting plate 211 to move horizontally along the translation guide rail on the mounting frame by driving the translation lead screw and the translation nut, thereby driving the clamping unit and the layer height detection unit to move closer to or away from the copper tube lifting and feeding mechanism, so as to realize the clamping unit to clamp the copper tube to be inserted and drive the clamped copper tube to the next process station.

[0095] In a specific embodiment, a material-carrying unit limiting device 14 is provided on the upper side of the support 13, and positioning blocks 117 are provided on both sides of the mobile vehicle 112 corresponding to the positions of the material-carrying unit limiting device.

[0096] like Figure 4 , Figure 6 As shown, the material loading unit limiting device 14 includes a limiting drive motor 141 and a positioning pin 142 connected to the limiting drive motor. The positioning pin is provided with a pair of oppositely arranged plates. The direction of the pair of plates is the direction in which the moving vehicle 112 enters or leaves the bracket. When the moving vehicle 112 enters the bracket, the limiting drive motor can drive the positioning pin to move towards the positioning block, driving the two plates on the positioning pin to both sides of the positioning block.

[0097] The limit drive motor is mounted on the bracket via a sliding connecting plate. Before the moving carriage 112 enters the bracket, the positioning pin is located in the fixed mounting seat. The limit drive motor and the fixed mounting seat can slide and adjust their positions in the sliding connecting plate in the lateral direction. After the moving carriage 112 enters the bracket, the limit drive motor drives the positioning pin to extend out of the fixed mounting seat and move towards the positioning block. When the two plates located at the positioning pin 142 are driven to both sides of the positioning block 117, the positioning pin 142 and the positioning block 117 cooperate to limit the lateral position of the moving carriage 112, preventing the moving carriage 112 from undergoing large displacement, thereby ensuring the stability of the position of the moving carriage 112, the loading platform on the moving carriage, and the copper tube to be inserted.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
