Description

Technical Field

[0001] The utility model relates to the field of terminal processing equipment, and more specifically to a double-head terminal plastic sealing machine. Background Art

[0002] From the drawings in the specification Figure 1 As shown, an existing column terminal needs to be installed in the inner cavity of a plastic tube and a hot air gun is used to heat the two ends of the plastic tube so that the two ends of the plastic tube shrink due to the heat, so that the column terminal is limited to the middle of the plastic tube, so that subsequent wires or other terminals are inserted from the ends of the plastic tube and electrically connected to the column terminal. Most existing processes use manual assembly of the plastic tube and place the plastic tube on a fixture, followed by heating with a hot air gun and finally manual collection. Such processing is a semi-automatic process, which not only results in low production efficiency, but also high labor costs. At the same time, there is a situation where the position of the column terminal in the inner cavity of the plastic tube is different, resulting in a high defective rate. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a double-head terminal plastic sealing machine which has a high degree of automation, saves labor costs and has a high product qualification rate.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-head terminal plastic sealing machine, comprising a workbench, a material transporting assembly positioned on the workbench, a first feeding assembly for feeding a plastic tube onto the material transporting assembly, a second feeding assembly for feeding a terminal onto the material transporting assembly, a clamping assembly for clamping the plastic tube with the terminal from the material transporting assembly, and a hot air blower positioned on one side of the clamping assembly and capable of heating the plastic tube, wherein the first feeding assembly and the second feeding assembly are arranged facing each other;

[0005] The material transport assembly includes a material transport tray with a center line parallel to the workbench surface, an anti-drop sleeve positioned on the workbench and sleeved outside the portion below the plane where the center line of the material transport tray is located, and a material transport shaft coaxially connected to the material transport tray and rotatable relative to the workbench, and a first group of stations distributed around the rotation center of the material transport tray is arranged on the peripheral wall of the material transport tray, and the first group of stations includes a plastic pipe station for feeding the first feeding assembly, a terminal station for feeding the second feeding assembly, and a material transfer station for feeding the plastic tube with the terminal onto the clamping assembly;

[0006] The clamping assembly includes two turntables arranged opposite to each other and whose center lines are parallel to the center line of the material transporting disk, a rotating shaft that simultaneously passes through the centers of the two turntables and can rotate relative to the workbench, two pulling motors that are both positioned on the workbench, and two clamping cylinders that are fixed relative to the workbench and correspond to the material shifting stations. The two turntables are each provided with a second group of stations that are distributed in a circle around the rotating shaft and are adjacent to the edges of the turntables. The second group of stations includes a loading station corresponding to the material shifting station, a plastic sealing station for blowing air with a heating fan, and an unloading station corresponding to the pulling motor. The second group of stations is each provided with a clamping rod that is limited to the turntable and can pass through the turntable, and an end cover that is fixedly connected to one end of the clamping rod and can be pulled by the pulling motor. The two turntables are each located between the two pulling motors and between the two clamping cylinders.

[0007] The plastic tube and the terminal are loaded onto the transport tray in turn through the first loading assembly and the second loading assembly so that the terminal is installed in the inner cavity of the plastic tube and moved to the material transfer station. The two clamping cylinders push the clamping rods at the corresponding loading station toward each other so that the two clamping rods partially penetrate into the plastic tube and clamp the terminal together. The plastic sealing operation and the product unloading and collection operation are completed in turn through the plastic sealing station and the unloading station.

[0008] As a further improvement of the present invention, it also includes a linkage component, which includes two linkage rods that are rotatably connected to the workbench and are respectively located on both sides of the vertical plane where the rotating shaft is located, a driving motor that can drive one of the linkage rods to rotate, and two chains that are simultaneously transmission-connected to the two linkage rods and correspond to the two turntables respectively. The two chains can be transmission-connected to the corresponding plastic sealing station and the station adjacent to the plastic sealing station. The second group of stations are also provided with a sleeve that is rotatably connected to the turntable and for the clamping rod to pass through, and a transmission wheel that is fixedly sleeved on one end of the sleeve and can be driven by the chain. The plastic sealing station is driven to rotate by the chain so that the plastic pipe can be evenly heated.

[0009] As a further improvement of the present invention, the clamping rod includes an alignment portion that can penetrate into the inner cavity of the plastic tube and can contact one end of the terminal, and a limiting portion that is coaxial with the alignment portion and can contact the end of the plastic tube. By the limiting portion contacting the end of the plastic tube and the alignment portion contacting the terminal, the terminal can be stopped in the middle position of the plastic tube.

[0010] As a further improvement of the present invention, a conical guiding portion is provided on the end of the alignment portion that can contact with the terminal.

[0011] As a further improvement of the utility model, the pulling motor includes a body fixed relative to the workbench, a pulling shaft capable of moving linearly relative to the body, and a C-shaped traction member fixedly connected to the pulling shaft. The end cover enters the inner cavity of the traction member from one side of the traction member through the rotation of the turntable, and the end cover is pulled by the traction member so that the opposing clamping rods move away from each other.

[0012] As a further improvement of the present invention, the material transport component also includes anti-slip sheets fixedly connected to the workbench and respectively located on both sides of the material transport tray. The two anti-slip sheets are respectively arranged corresponding to the plastic pipe station and the terminal station. The anti-slip sheets prevent the plastic pipe or terminal entering the corresponding station from continuing to move, so that the plastic pipe or terminal cannot leave the material transport tray.

[0013] As a further improvement of the present invention, the first loading assembly and the second loading assembly both include a vibration plate positioned on the workbench, a material channel connected to the vibration plate, a straight vibrator positioned below the material channel, a dividing block located at the end of the material channel, a dividing cylinder driving the dividing block to move linearly, a lifting cylinder positioned on one side of the material channel, and a baffle plate arranged on the other side of the dividing block relative to the material channel.

[0014] As a further improvement of the utility model, a material drop hole located below the unloading station is provided on the workbench.

[0015] The beneficial effects of the utility model are as follows: the plastic tube and the terminal are successively loaded onto the transport tray through the first loading assembly and the second loading assembly so that the terminal is installed in the inner cavity of the plastic tube and moved to the material shifting station; the two clamping cylinders push the clamping rods at the corresponding loading stations toward each other so that the two clamping rods partially penetrate into the plastic tube and clamp the terminal together; the plastic sealing operation and the product unloading and collection operation are successively completed through the plastic sealing station and the unloading station.

The rotating shaft 52 passes through the vertical plate and the two turntables 51 in sequence, and one end of the rotating shaft 52 is connected to the driving module. The driving module can drive the rotating shaft 52 to rotate. The other end of the rotating shaft 52 is limited on the vertical plate and can rotate relative to the vertical plate. The two turntables 51 are relatively stationary with the rotating shaft 52 through a key connection. The portion where the material transfer station 243 of the tray 21 is located is located between the two turntables 51. Both turntables 51 are provided with a second group of stations 55. The second group of stations 55 is composed of a plurality of stations distributed in a circle around the rotating shaft 52 and close to the edge of the turntable 51, including a loading station 551 corresponding to the material transfer station 243, a plastic sealing station 552 for blowing air with a hot air blower 6, and a discharging station 553 located at the lowest point of the turntable 51. The hot air blower 6 is located on the other side of the turntable 51 relative to the material transport tray 21. The second group of workstations 55 are each provided with a clamping rod 554 which is limited to the rotating disk 51 and can pass through the rotating disk 51, and an end cap 555 which is positioned on one end of the clamping rod 554. The clamping rod 554 can move linearly relative to the rotating disk 51. The end cap 555 is located at the end of the clamping rod 554 which is adjacent to the vertical plate or the driving module. The diameter of the end cap 555 is larger than the diameter of the clamping rod 554. The diameter of the clamping rod 554 between the two rotating disks 51 is smaller than the diameter of the inner cavity of the plastic tube. The motors 53 are respectively positioned on the vertical plate and the driving module, and the output shafts of the two pulling motors 53 are both oriented toward the unloading station 553 of the corresponding turntable 51. A finger cylinder for clamping the end cover 555 can be fixedly connected to the output shaft of the pulling motor 53. The body of the pulling motor 53 on the driving module is accommodated inside the driving module. The two clamping cylinders 54 are respectively positioned on the vertical plate and the driving module, and the output shafts of the two clamping cylinders 54 correspond to the loading stations 551 on the two turntables 51.

[0030] In the initial state, the distance between the relative clamping rods 554 on the two turntables 51 is greater than the length of the plastic tube, and the material hole of the dividing block 34 is connected with the end of the corresponding material channel 32; the processing technology is as follows: in the first step, the two vibrating disks 31 transport the terminals and the plastic tubes to the corresponding material channels 32 respectively, and under the action of the straight vibrator 33, the terminals and the plastic tubes are moved to the ends of the material channels 32 and enter the material holes until the terminals and the plastic tubes entering the material holes touch the corresponding baffle plates 37 respectively; in the second step, the two dividing cylinders 35 drive the corresponding dividing block 34 to move to the front of the corresponding pushing cylinder 36 and the output shaft of the pushing cylinder 36 is opposite to the material hole of the dividing block 34, and the dividing block 34 is not opened The part with material holes prevents the terminal or plastic tube in the material channel 32 from moving forward further; in the third step, the ejecting cylinder 36 corresponding to the plastic tube station 241 pushes the plastic tube in the corresponding material block 34 into the through groove at the plastic tube station 241 and resets it, and then the plastic tube is moved to the terminal station 242 by rotating the material transport plate 21, and then the ejecting cylinder 36 corresponding to the terminal station 242 pushes the terminal in the corresponding material block 34 into the terminal station 242 and the terminal is pushed into the inner cavity of the plastic tube, and then the ejecting cylinder 36 corresponding to the terminal station 242 is reset; in the fourth step, the material transport plate 21 continues to rotate, and the plastic tube with the terminal passes through the inner cavity of the anti-detachment sleeve 22 and moves to the transport plate 21. The material station 243 corresponds to the loading station 551 on the turntable 51; the fifth step, the two clamping cylinders 54 respectively push the corresponding clamping rods 554 to move toward each other, and the two clamping rods 554 partially penetrate the inner cavity of the plastic tube and drag the plastic tube, then the turntable 51 rotates and moves the plastic tube with the terminal out of the material transfer station 243; the sixth step, the turntable 51 rotates to move the plastic tube with the terminal to the plastic sealing station 552 and stops, and the hot air blower 6 blows hot air with a higher temperature to the plastic sealing station 552, the plastic tube shrinks due to the heat, the plastic tube tightly hugs the terminal and the inner diameter of the two ends of the plastic tube is smaller than the diameter of the terminal; the seventh step, the turntable 51 continues to rotate and the plastic-sealed product Move to the unloading station 553, the end cap at the unloading station 553 moves to the corresponding finger cylinder, the two finger cylinders start and clamp the corresponding end cap, then the two pulling motors 53 respectively drive the corresponding finger cylinders to move away from the turntable 51, and the two clamping rods 553 move away from each other until the distance between the two clamping rods 553 is greater than the length of the plastic tube, and the plastic-sealed product detaches from the unloading station 553 and falls, and a collection box can be placed under the unloading station 553 to collect the product, and the clamping rods 554 pulled apart from each other will rotate again with the turntable 51 to the loading station 551 for next use; repeating the above steps, the terminals and plastic tubes can be assembled, plastic-sealed and collected one by one;

[0031] Compared with the existing technology, this design can automatically complete the assembly and plastic sealing between the terminal and the plastic tube and collect them at the end. It has a high degree of automation, high processing efficiency, reduces labor costs, and effectively avoids human operation errors to improve product qualification rate.

[0032] As a specific implementation method of the improvement, refer to Figures 2 to 4 As shown, a linkage assembly 7 is also included, and the linkage assembly 7 includes two linkage rods 71, a drive motor 72 and two chains 73. The two linkage rods 71 ​​are gear rods and have two gears on the rod body that can transmit with the chain 73. The length directions of the two linkage rods 71 ​​are parallel to the axial direction of the rotating shaft 52. The two linkage rods 71 ​​are rotatably connected to the workbench 1 and are respectively located on both sides of the vertical plane where the rotating shaft 52 is located. The two linkage rods 71 ​​are located between the drive module and the vertical plate. The drive motor 72 is positioned on the workbench 1 and the output shaft passes through the drive module. The second group of workstations 55 are each provided with a sleeve 556 and a transmission wheel 557. The sleeve 556 is sleeved outside the corresponding clamping rod 554 and the sleeve 556 is rotatably connected to the turntable 51. The transmission wheel 557 is installed on the end of the sleeve 556 adjacent to the end cover 555 by a key connection. A chain 73 is successively wound around the gears on the same side of the two linkage rods 71 ​​and around the top of the turntable 51 and the transmission wheel 557 adjacent to the top. Then, the chain 73 can be connected with the corresponding plastic sealing workstation 552. The chain 73 is connected to the gears on another turntable 51 and another group of linkage rods 71. During the processing, the drive motor 72 always drives the connected linkage rods 71 ​​to rotate. The linkage rods 71 ​​drive the corresponding transmission wheels 557 and another linkage rod 71 to rotate through the chain 73. Then, some sleeves 556 in the second group of stations 55 rotate with the corresponding clamping rods 554 relative to the turntable 51. When the plastic pipe moves from the feeding station 531 to the plastic sealing station 532, the corresponding transmission wheels 557 It will mesh with the chain 73 and be transmitted, and the corresponding sleeve 556 will drive the clamping rod 554 and the plastic tube to rotate together. When the plastic tube moves from the plastic sealing station 532 to the unloading station 553, the corresponding transmission wheel 557 will separate from the chain 73 and stop rotating, and the corresponding sleeve 556, the clamping rod 554 and the plastic tube will all stop rotating. Such a design can enable the plastic tube equipped with the terminal to be heated by the heat blower 6 in a rotating state, and the plastic tube is heated evenly and can be deformed evenly, which makes up for the defect that the plastic tube in the previous embodiment is only partially heated and causes local deformation.

[0033] As a specific implementation of the improvement, since the position of the plastic tube after being pushed into the material transport tray 21 is not unique, there is a deviation between the middle position of the plastic tube and the position of the symmetric plane between the two turntables 51, which will cause the terminal to not be located in the middle position of the plastic tube when the two clamping rods 554 subsequently drag the plastic tube, thereby causing an increase in the defective rate. To solve the above problem, refer to Figure 6As shown, all clamping rods 554 include an alignment portion 558 and a limiting portion 559. The diameter of the alignment portion 558 is smaller than the diameter of the inner cavity of the plastic tube, and the diameter of the limiting portion 559 is larger than the diameter of the inner cavity of the plastic tube. The limiting portion 559 passes through the turntable 51 and is coaxially arranged with the alignment portion 558. In the process of the two clamping rods 554 moving toward each other, the two alignment portions 558 respectively penetrate into the two ends of the plastic tube and clamp the terminal together. The shoulders formed by the limiting portion 559 and the alignment portion 558 touch the end face of the plastic tube. The plastic tube with position deviation will first touch one of the shoulders and move relative to the terminal under the push of the shoulder until the other end of the plastic tube is close to or touches the other shoulder. Then the terminal is located in the middle of the plastic tube. Such a design can ensure that the position of the terminal in the plastic tube is fixed, effectively improving the qualified rate of the product.

[0034] As a specific implementation of the improvement, due to the difference between the axis of the alignment portion 558 and the axis of the plastic tube in the material transport tray 21, the alignment portion 558 cannot smoothly enter the inner cavity of the plastic tube, thereby affecting the subsequent clamping effect of the plastic tube. To solve the above problem, refer to Figure 6 As shown, a conical guide portion 550 is provided on the end of the alignment portion 558 that can contact the terminal. In the process of the two clamping rods 554 moving toward each other, the tip of the guide portion 550 first enters the inner cavity of the plastic tube and as the subsequent plastic tube opening slides relative to the conical surface of the guide portion 550, the axial position of the plastic tube is adjusted until the alignment portion 558 enters the plastic tube and the axial position of the plastic tube is adjusted into place. Such a design can ensure the smoothness of the clamping rod 554 inserted into the plastic tube, thereby improving the clamping efficiency.

[0035] As a specific implementation method of the improvement, refer to Figure 6 As shown, the two pulling motors 53 each include a body 531 fixed relative to the workbench 1, a pulling shaft 532 capable of linearly moving relative to the body 531, and a C-shaped traction member 533 fixedly connected to the pulling shaft 532. The body 531 connected to the driving module is accommodated inside the driving module, the inner cavity of the traction member 533 can be used to accommodate the end cover, and the distance between its two opposite ends is between the diameter of the end cover and the diameter of the clamping rod 554. During the processing, as the turntable 51 rotates, the end cover moves from one side of the traction member 533 to the inner cavity of the traction member 533, and the clamping rod 554 moves from one side of the traction member 533 to between the two opposite ends of the traction member 533. Then the body 531 drives the pulling shaft 532 to move linearly, and the two traction members 533 move away from each other and drive the corresponding end covers to move. Compared with the design of the finger cylinder in the first embodiment, such a design can simplify the operating procedures and reduce the cost required for the equipment.

[0036] As a specific implementation of the improvement, when the plastic tube or terminal is pushed into the first group of stations 24 on the transport tray 21, the plastic tube or terminal may be pushed out of the transport tray 21 under the action of inertia. Figure 5 As shown, the material transport component 2 also includes anti-slip sheets 25 fixedly connected to the workbench 1 and respectively located on both sides of the material transport tray 21. The two anti-slip sheets 25 are respectively arranged corresponding to the plastic pipe station 241 and the terminal station 242. The anti-slip sheets 25 can be integrally formed with the anti-slip sleeve 22. When the plastic pipe or the terminal is pushed into the through groove of the material transport tray 21, the plastic pipe or the terminal will contact with the corresponding anti-slip sheet 25 and stay in the through groove. Such a design can avoid the loss of the terminal or the plastic pipe, ensure the orderly processing, and indirectly improve the production efficiency.

[0037] As a specific implementation method of the improvement, refer to Figure 4 As shown, the workbench 1 is provided with a drop hole 11 located below the unloading station 553, and a collection box can be set below the workbench 1 surface for collecting products. Compared with the design of placing the collection box on the workbench 1 in the first embodiment, such a design can effectively reduce the height of the rotating shaft 52 relative to the workbench 1 surface, thereby reducing the size requirements of other components. At the same time, replacing the collection box below the workbench 1 surface can avoid affecting the normal operation of other components, thereby ensuring production efficiency and improving safety for the staff.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
