Description

Technical Field

[0001] This utility model relates to a production equipment for electric heating tubes, and more particularly to an automated equipment for applying adhesive to ceramic beads and rivet the heating tube straight tube guide rod. Background Technology

[0002] As a core component widely used in home appliances, industrial heating and other fields, electric heating tubes usually require ceramic beads to be installed at their ends to achieve insulation, positioning and protection functions. The installation accuracy and stability of the ceramic beads directly affect the insulation performance, structural strength and service life of the electric heating tube.

[0003] Currently, the installation of ceramic beads for electric heating elements still largely relies on traditional processing methods, with two main approaches: one is purely manual installation, where operators manually grab the ceramic beads and place them one by one onto the straightened heating wire, then adjust the spacing and position of the ceramic beads using auxiliary tools. This method is greatly affected by factors such as the operator's skill level and fatigue, resulting in low installation efficiency and difficulty in meeting the needs of mass production.

[0004] The second is the semi-automated installation mode, in which some companies introduce traditional feeding equipment such as vibratory feeders to achieve the initial sorting and conveying of ceramic beads, and then manual assistance is required to complete the clamping and setting operations, which fails to fundamentally solve the problem of reliance on manual labor. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an automated device for aligning and attaching ceramic beads to a straight heating tube guide rod.

[0006] The technical solution adopted by this utility model to solve its technical problem is: An automated equipment for straightening heating tubes, applying adhesive, and rivetizing ceramic beads includes an assembly frame. A feeding mechanism is located at the starting end of the assembly frame. Two ceramic bead installation stations are installed on the assembly frame. From front to back, each ceramic bead installation station is equipped with a pre-feeding mechanism, a guide rod straightening mechanism, an adhesive injection mechanism, a ceramic bead feeding mechanism, and a guide rod clamping mechanism. A transfer mechanism is installed on the assembly frame to transfer heating tubes from each process to the next process. A rotating robot arm for flipping the heating tubes 180° vertically is installed between the two ceramic bead installation stations on the transfer mechanism. A unloading mechanism is installed at the end of the assembly frame. A picking mechanism is also located at the starting end of the assembly frame to grab the heating tubes from the feeding mechanism and feed them into the pre-feeding mechanism.

[0007] The feeding mechanism is provided with a storage area and a feeding area. The height of the feeding area is higher than that of the storage area. The storage area is inclined downward toward the feeding area, and the feeding area is inclined downward away from the storage area. A feeding plate lifted by a first cylinder is installed at the junction of the storage area and the feeding area. A positioning cylinder for pushing the heating tube to position is installed at one end of the feeding area.

[0008] The pre-feeding mechanism includes two first finger cylinders installed vertically. In the second set of ceramic bead installation station, a second cylinder for pushing and positioning the heating tube is installed below the pre-feeding mechanism.

[0009] The straightening mechanism for the guide rod includes a straightening base, on which a first rotary motor is installed, which is driven to slide up and down by a third cylinder. A three-jaw cylinder is installed on the rotating shaft of the first rotary motor.

[0010] The glue dispensing mechanism includes a glue dispensing base, on which a glue dispensing head and a glue tank are mounted. The glue dispensing head and the glue tank are connected through a glue dispensing valve pipeline.

[0011] The ceramic bead feeding mechanism includes a vibratory feeder mechanism and a feeding mechanism. The feeding mechanism includes a positioning component connected to the discharge channel of the vibratory feeder mechanism. A limiting baffle driven by a fourth cylinder is installed above the positioning component, and a pin driven by a fifth cylinder is installed at the bottom of the positioning component. The feeding mechanism also includes a first rotary cylinder driven by a clamping mechanism. A second finger cylinder for clamping ceramic tiles is installed on the rotating shaft of the first rotary cylinder.

[0012] The guide rod clamping mechanism includes a clamping base, on which a clamping fixing seat driven by a sixth cylinder is installed. A scissor-type clamping arm is installed at the lower end of the clamping fixing seat, and a clamping cylinder that drives the scissor-type clamping arm is installed on the upper side of the clamping fixing seat.

[0013] The cutting mechanism includes a first vertical sliding seat driven by a vertical screw mechanism, a first horizontal sliding seat driven by a horizontal screw mechanism on the first vertical sliding seat, and two identical cutting robot arms mounted on the first horizontal sliding seat. The flipping robot arm is mounted between the two cutting robot arm groups.

[0014] The material handling mechanism includes a material handling frame, a rotating seat driven by a second rotary motor on the material handling frame, an adjusting sliding seat driven to move back and forth on the rotating seat by a first servo motor, a first mounting seat driven by a third rotary motor mounted on the adjusting sliding seat, and third finger cylinders mounted at both ends of the first mounting seat.

[0015] The feeding mechanism includes a feeding slide seat that moves up and down driven by a second servo motor, a feeding rotary seat driven by a fourth rotary motor mounted on the feeding slide seat, a second mounting seat driven by a fifth rotary motor mounted on the feeding rotary seat, and fourth finger cylinders mounted at both ends of the second mounting seat.

[0016] The beneficial effects of this utility model are as follows: This utility model includes an assembly frame, a feeding mechanism, and a picking mechanism. The assembly frame is equipped with two sets of ceramic bead installation stations and a transfer and cutting mechanism.

The ceramic bead installation stations are equipped with a pre-feeding mechanism, a guide rod straightening mechanism, a glue injection mechanism, a ceramic bead feeding mechanism, and a guide rod clamping mechanism in sequence from front to back. A unloading mechanism is installed at the end of the assembly frame. During operation, after the ceramic bead installation station completes the installation of ceramic beads at one end of the electric heating tube, it is flipped 180° by the flipping robot and then transferred to the next set of ceramic bead installation stations to complete the installation of ceramic beads at the other end. Finally, the unloading mechanism removes the finished product, realizing the full automation of the installation process of ceramic beads at both ends of the electric heating tube, improving installation accuracy and production efficiency, ensuring product consistency, and is suitable for large-scale electric heating tube production scenarios.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0021] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0022] Reference Figure 1-14 An automated equipment for straightening heating tubes, applying adhesive, and rivetizing ceramic beads includes an assembly frame 1. A feeding mechanism 2 is placed at the starting end of the assembly frame 1. Two ceramic bead installation stations are installed on the assembly frame 1. From front to back, each ceramic bead installation station is equipped with a pre-feeding mechanism 3, a guide rod straightening mechanism 4, an adhesive injection mechanism 5, a ceramic bead feeding mechanism 6, and a guide rod clamping mechanism 7. A transfer cutting mechanism 8 is installed on the assembly frame 1 to transfer heating tubes from each process to the next process. A rotating manipulator 10 for flipping the heating tubes 180° vertically is installed between the two ceramic bead installation stations on the transfer cutting mechanism 8. A unloading mechanism 50 is installed at the end of the assembly frame 1. A picking mechanism 9 is also placed at the starting end of the assembly frame 1 to grab the heating tubes from the feeding mechanism 2 and feed them into the pre-feeding mechanism 3.

[0023] Before startup, workers place all the heating tubes on the feeding mechanism 2. After startup, the picking mechanism 9 removes one heating tube from the feeding mechanism 2 and sends it to the pre-feeding mechanism 3. Then, through the transfer cutting mechanism 8, it is moved to the ignition straightening mechanism 4 to straighten the heating tube, facilitating the subsequent installation of ceramic beads. At the same time, the picking mechanism 9 removes another heating tube from the feeding mechanism 2 and sends it to the pre-feeding mechanism 3. After the ignition straightening of the heating tube is completed, the transfer cutting mechanism 8 moves it to the glue injection mechanism 5 for glue application, and then moves it to the ceramic bead feeding mechanism 6 through the transfer cutting mechanism 8. The ceramic beads are inserted into the lead rod of the heating tube and pressed firmly. Then, the lead rod clamping mechanism 8 moves the lead rod clamping mechanism 7 to deform the lead rod clamping mechanism of the heating tube (when the heating tube is rotated 180°, the ceramic beads will be restricted due to the deformation of the clamping mechanism, preventing them from falling off). Then, the rotating robot arm 10 grabs the heating tube and rotates it 180°. The second set of ceramic beads is then installed. Finally, the unloading mechanism 50 removes the ceramic beads and places them in the storage position. This process automates the entire process of installing ceramic beads at both ends of the electric heating tube, improves installation accuracy and production efficiency, ensures product consistency, and is suitable for large-scale electric heating tube production scenarios.

[0024] The feeding mechanism 2 is provided with a storage area 11 and a feeding area 12. The height of the feeding area 12 is higher than that of the storage area 11. The storage area 11 is inclined downward toward the feeding area 12, and the feeding area 12 is inclined downward away from the storage area 11. A feeding plate 14, which is lifted by a first cylinder 13, is installed at the junction of the storage area 11 and the feeding area 12. A positioning cylinder 15 for positioning the heating tube is installed at one end of the feeding area 12. When the heating tube is placed in the storage area 11, it will roll toward the feeding area 12, ensuring that there is always a heating tube above the feeding plate 14. After the first cylinder 13 lifts the feeding plate 14, it will simultaneously drive a heating tube to rise. When it reaches the feeding area 12, it will roll into the feeding area 12. Finally, the positioning cylinder 15 pushes the heating tube so that its other end abuts against the positioning plate on the feeding area 12, thus completing the positioning.

[0025] Furthermore, the position of the positioning plate can be adjusted to accommodate different heating tube lengths.

[0026] Furthermore, the top surface of the feeding plate 14 is provided with a certain slope to ensure that the heating tube can roll towards the feeding area 12.

[0027] Furthermore, a first sensor for detecting whether a heating element is present is provided on the feeding area 12. The first sensor is connected to the solenoid valve of the first cylinder 13. When a heating element is detected on the feeding area 12, the first cylinder 13 will not start, thus avoiding the situation where two heating elements stick together on the feeding area 12, and the material handling mechanism 9 removes the heating element, causing the other heating element to be deformed and damaged.

[0028] The pre-feeding mechanism 3 includes two first finger cylinders installed vertically. In the first set of ceramic bead installation stations, positioning has been completed due to the pushing of the positioning cylinder 15. Therefore, the pre-feeding mechanism 3 in the first set of ceramic bead installation stations does not require additional positioning. However, the heating tube is prone to slight bending during storage and transportation, which causes the actual ceramic bead installation position to deviate after the heating tube is rotated 180°. For example, if a heating tube is 130 cm long, it may be bent during storage and transportation, resulting in an actual length of 129 cm. After the heating tube is rotated 180°, the actual installation position of the ceramic bead on the heating tube is 1 cm away from the automated installation of the equipment. Therefore, in the second set of ceramic bead installation stations, a second cylinder for pushing and positioning the heating tube is installed below the pre-feeding mechanism 3. In addition, a positioning baffle is also required. When the heating tube is pushed to abut against the positioning baffle, the positioning is completed.

[0029] The straightening mechanism 4 for the heating element includes a straightening base 17. A first rotary motor 19, driven to slide up and down by a third cylinder 18, is mounted on the straightening base 17. A three-jaw cylinder 20 is mounted on the rotating shaft of the first rotary motor 19. During storage, transportation, and other processes, the heating element may bend or deform. Therefore, it is necessary to straighten the heating element to facilitate the insertion of the ceramic beads. During operation, the three-jaw cylinder 20 grips the heating element (the three-jaw cylinder has a clearance structure corresponding to the heating element. When the three jaws grip, they form a circle, which is slightly larger than the diameter of the heating element). The third cylinder 18 and the first rotary motor 19 start synchronously, causing the three-jaw cylinder 20 to rotate and rise. During this process, the heating element is straightened.

[0030] The glue dispensing mechanism 5 includes a glue dispensing base 21, on which a glue dispensing head 23 and a glue tank 22 are mounted. The glue dispensing head 23 and the glue tank 22 are connected by a glue dispensing valve 24.

[0031] Furthermore, the dispensing head 23 is driven by the eleventh cylinder 16. When dispensing, the eleventh cylinder 16 drives the dispensing head 23 to approach the upper end of the heating tube. After dispensing is completed, the eleventh cylinder 16 drives the dispensing head 23 to reset, so as to avoid interference when the cutting mechanism 8 cuts the heating tube.

[0032] Furthermore, a seventh finger cylinder is installed on the assembly frame 1 at the position corresponding to the glue dispensing mechanism 5. The transfer cutting mechanism 8 moves the heating tube to the seventh finger cylinder, where it is grasped by the seventh finger cylinder. Then, the glue dispensing mechanism 5 applies glue, and the transfer cutting mechanism 8 removes the heating tube from the seventh finger cylinder and moves it to the next process.

[0033] The ceramic bead feeding mechanism 6 includes a vibratory feeder mechanism 25 and a feeding mechanism 26. The feeding mechanism 26 includes a positioning element 27 connected to the discharge channel of the vibratory feeder mechanism 25. A limiting baffle 29 driven by a fourth cylinder 28 is installed above the positioning element 27. A pin 31 driven by a fifth cylinder 30 is installed at the bottom of the positioning element 27. The feeding mechanism 26 also includes a first rotary cylinder 73 driven by a clamping mechanism 32. A second finger cylinder 33 for clamping ceramic tiles is installed on the rotating shaft of the first rotary cylinder 73.

[0034] After the ceramic bead is fed into the positioning member 27 by the vibratory feeder mechanism 25, the limiting baffle 29 is driven by the fourth cylinder 28 to block the positioning member 27. Then, the ejector pin 31 is driven by the fifth cylinder 30 to lift up, thereby lifting the ceramic bead. The limiting baffle 29 is used to prevent the ceramic bead from being bounced away, reduce material loss and process interruption, and improve the overall stability of operation. Finally, the ceramic bead is grabbed and transported to the installation position by the cooperation of the clamping mechanism 32 and the second finger cylinder 33. During installation, the clamping mechanism 32 is activated in conjunction with the first rotary cylinder 73 to make the ceramic bead rotate and move down. Due to storage and other factors, the position of the ceramic bead for the electric heating tube installation part is deformed. With the help of the rotational guiding effect, it can be installed smoothly, avoiding the situation of the ceramic bead getting stuck or not installed in place. This ensures that the ceramic bead and the end of the electric heating tube are tightly attached, which not only improves the insulation performance and structural stability of the electric heating tube, but also significantly improves the product qualification rate and adapts to the needs of large-scale automated production.

[0035] The ceramic bead feeding mechanism 6 is equipped with a sensor for detecting the ceramic tiles on the ejector pin 31. This sensor can detect in real time whether there are ceramic beads on the ejector pin, avoiding empty clamping and preventing the ceramic beads from being installed, thus improving the product qualification rate.

[0036] The positioning component 27 is provided with a positioning groove connected to the discharge channel. The bottom of the positioning groove is through, and the upper end of the ejector pin 31 is inserted into the positioning groove. When the ceramic bead is inserted into the positioning groove, the positioning of the ceramic bead is completed. After being lifted by the ejector pin 31, it can wait for the finger cylinder to pick it up.

[0037] The clamping mechanism 32 includes a second transverse sliding seat 59 driven by a seventh cylinder 58 in the transverse direction, and a second vertical sliding seat 61 driven by an eighth cylinder 60 in the vertical direction mounted on the second transverse sliding seat 59. The first rotary cylinder 73 is mounted on the second vertical sliding seat 61 to achieve precise spatial transfer of ceramic beads after gripping. With the rotation function of the rotary cylinder, an integrated automated process of "feeding-positioning-lifting-gripping-rotating assembly" is formed. The actions are smoothly connected and do not require manual assistance in cleaning or adjusting angles. Compared with traditional manual and semi-automatic equipment, it greatly reduces human intervention, improves production cycle, avoids the uncertainty of manual operation, ensures the consistency of assembly quality in mass production, and is suitable for the large-scale production needs of electric heating tubes.

[0038] The lead rod clamping mechanism 7 includes a clamping base 34, on which a clamping fixing seat 74 driven by a sixth cylinder 35 is mounted. A scissor-type clamping arm 36 is mounted at the lower end of the clamping fixing seat 74, and a clamping cylinder 37 that drives the scissor-type clamping arm 36 is mounted on the upper side of the clamping fixing seat 74. When the clamping cylinder 37 is driven, the ends of the scissor-type clamping arms 36 will come together through the corresponding hinge points (similar to the structure of scissors, which is the existing structural principle), thereby deforming the heating tube lead rod clamp. Through this deformation position, the detachment of the ceramic bead can be restricted, and it will not fall off even after the flipping robot arm 10 is flipped 180°.

[0039] The cutting mechanism 8 includes a first vertical sliding seat 39 driven by a vertical screw mechanism 38, a first horizontal sliding seat 41 driven by a horizontal screw mechanism 400 on the first vertical sliding seat 39, and two identical cutting robot arms mounted on the first horizontal sliding seat 41. The flipping robot arm 10 is mounted between the two cutting robot arms.

[0040] The cutting robot group consists of several cutting robots 62. The number of cutting robots 62 matches the number of processes in the automated equipment for straightening heating tubes, aligning guide rods, applying glue, riveting ceramic beads, and clamping guide rods. In this application, the installation of ceramic tiles includes five processes: positioning of electric heating tubes, straightening of guide rods, applying glue, installing ceramic beads, and riveting guide rods. Therefore, the number of cutting robots 62 is four. The flipping robot 10 is used as the fifth cutting robot. That is, the flipping robot 10 has both the function of cutting heating tubes and the function of flipping heating tubes.

[0041] That is, for the previous group of cutting robot arms, it is used as the fifth cutting robot arm, and for the next group of cutting robot arms, it is used as the first cutting robot arm.

[0042] The cutting robot 62 is fixed to a first fixed seat 63 on the first transverse sliding seat 41. A third mounting seat 65 driven by a ninth cylinder 64 is installed on the first fixed seat 63. A fifth finger cylinder 66 is installed at the upper and lower ends of the third mounting seat 65.

[0043] The flipping manipulator 10 includes a second fixed seat 67 fixed on the first transverse sliding seat 41. A third fixed seat 69 driven by a tenth cylinder 68 is mounted on the second fixed seat 67. A second rotary cylinder 70 is mounted on the third fixed seat 69. A fourth mounting seat 71 is mounted on the rotating shaft of the second rotary cylinder 70. A sixth finger cylinder 72 is mounted at the upper and lower ends of the fourth mounting seat 71.

[0044] Furthermore, the initial positions of the fifth finger cylinder 66 and the sixth finger cylinder 72 are consistent (i.e., the distance from the heating tube is consistent before the heating tube is grasped). When the heating tube needs to be grasped, the ninth cylinder 64 and the tenth cylinder 68 are synchronously driven to extend, and the heating tube is grasped by the finger cylinders. Then, the tenth cylinder 68 extends further to push the heating tube out again. Then, the second rotary cylinder 70 is activated to rotate the heating tube 180° (to avoid collision with the transfer robot group when the heating tube is rotated) and retract it, so that the positions of all heating tubes are consistent again. At this time, through the transmission of the transverse screw mechanism 40, the heating tubes of each process are transferred to the corresponding position of the next process. The ninth cylinder 64 and the tenth cylinder 68 are synchronously driven to retract and send the heating tube to the workstation. The ninth cylinder 64 and the tenth cylinder 68 are synchronously driven to retract and reset again. Finally, through the reverse transmission of the transverse screw mechanism 40, the reset is achieved, waiting for the next transfer.

[0045] Both the vertical lead screw mechanism 38 and the horizontal lead screw mechanism 40 are driven by motors. The horizontal lead screw mechanism 40 is used as a transmission structure for transferring the heating tube, while the vertical lead screw mechanism 38 serves as an adjustment structure. It adjusts the position of the transfer robot group according to the different lengths of the heating tubes, so that the transfer robot group is located in the center of the heating tube. When the flipping robot 10 flips the heating tube 180°, the installation position of the heating tube is still in a reasonable position, reducing the posture deviation of the slender heating tube during the transfer process and ensuring the accuracy of the ceramic bead assembly position and the overall assembly quality.

[0046] The material handling mechanism 9 includes a material handling frame 42, a rotating seat 44 driven by a second rotary motor 43 on the material handling frame 42, an adjusting sliding seat 46 driven to move back and forth on the rotating seat 44 by a first servo motor 45, a first mounting seat 48 driven by a third rotary motor 47 mounted on the adjusting sliding seat 46, and third finger cylinders 49 mounted at both ends of the first mounting seat 48.

[0047] During material handling, since the heating element on the feeding area 12 is placed horizontally, the first mounting base 48 is rotated 90° by the third rotary motor 47, so that the two third finger cylinders 49 are positioned horizontally. Then, the rotating base 44 is rotated 90° by the second rotary motor 43, so that the two third finger cylinders 49 are aligned with the heating element. Finally, the adjusting sliding base 46 is driven forward by the first servo motor 45, and the two third finger cylinders 49 are used to grab the heating element. Subsequently, the first servo motor 45, the second rotary motor 43 and the third rotary motor 47 work together to drive the two third finger cylinders 49 to send the heating element into the pre-feeding mechanism 3.

[0048] The unloading mechanism 50 includes an unloading sliding seat 52 driven to move up and down by a second servo motor 51. An unloading rotating seat 54 driven by a fourth rotary motor 53 is mounted on the unloading sliding seat 52. A second mounting seat 56 driven by a fifth rotary motor 55 is mounted on the unloading rotating seat 54. Fourth finger cylinders 57 are mounted at both ends of the second mounting seat 56. The fourth rotary motor 53 and the fifth rotary motor 55 work together to drive the two fourth finger cylinders 57 to remove the processed heating tube and turn it from a vertical state to a horizontal state. By starting the second servo motor 51, the heating tube is placed on the unloading device (which is placed around the unloading mechanism 50 and is specifically used to store the heating tube).

[0049] Furthermore, the feeding mechanism 50 is equipped with a sensor for detecting the position of the heating tubes on the feeding device. When each heating tube is placed, the height of the highest heating tube on the feeding device is increased by the diameter of the heating tube. The sensor ensures that the drop of the heating tube remains constant when the feeding mechanism 50 lowers the heating tube, thus avoiding damage to the heating tube or collision with the heating tube due to a large drop.
