Two sets of double-axis telescopic components are also installed at the bottom of the lifting beam and are symmetrically installed on the left and right sides of the lifting rod. A guide assembly is mounted on the machine tool main frame and located on the left and right sides of the electric conveyor belt. The guide assembly includes slides that are fitted and mounted on both sides of the electric conveyor belt. A rocker is mounted on the side of the slide away from the electric conveyor belt and the rocker is not connected to the edge of the slide. The rocker is connected to the machine tool main frame. A guardrail frame is installed at the rear end of the machine tool main frame. An elastic cross plate is connected to the middle of the guardrail frame and the elastic cross plate is located at the center of the rear end of the electric conveyor belt. A spring-loaded telescopic rod is inserted into the middle of the side of the elastic cross plate facing the electric conveyor belt, and the spring-loaded telescopic rod can spring and extend on the elastic cross plate. A folding frame is installed at the front bottom of the machine tool main frame. A motor is suspended at the top of the folding frame. An eccentric shaft is installed at the bottom of the motor. A wire-pulling tooth is installed at the bottom pin of the eccentric shaft. A wire stripper is installed below the wire-pulling tooth and is installed directly below the motor.
[0005] Preferably, a pressing plate is installed at the bottom of the dual-axis telescopic component, and the pressing plate is telescopically installed with the hanging beam through the dual-axis telescopic component, and the pressing plate is pressed against the cable clamp seat through the dual-axis telescopic component.
[0006] Preferably, a disc frame is installed at the bottom of the lifting rod, and two welded parts are installed symmetrically at the end of the disc frame away from the lifting beam for controlling the opening and closing of the welding head.
[0007] Preferably, one end of the welded component is connected to a soldering body for controlling the total amount of solder delivered to the joint through the soldering bath, and the end of the soldering body away from the lifting beam is equipped with welding heads at equal intervals.
[0008] Preferably, each of the welding heads has a solder inlet on its side wall, and the solder inlet is connected to the inner side of the upper solder body. The welding head is hoisted above the square slot by a disc frame, lifting rod and lifting beam. The detection head is hoisted above another square slot on the rear side of the square slot, so that the welding joint of the completed joint can be detected by the detection head.
[0009] Preferably, one end of the welded component is connected to a cable tester, and the end of the cable tester away from the suspension beam is equipped with a detection head. The cable tester is used to control the detection head to test the joint and can sound an alarm for problematic structures.
[0010] Preferably, the slide is equipped with wire clamps at equal intervals, and the wire clamps are capable of sliding back and forth on the slide.
[0011] Preferably, the end of the elastic telescopic rod near the electric conveyor belt is connected to a rocker arm, and the rocker arm can be fitted to the surface of the electric conveyor belt. Under the elastic pushing of the elastic telescopic rod, the end of the rocker arm near the electric conveyor belt can be inserted into the notch opened on the side of the square slot.
[0012] Preferably, a cutting groove is provided at the top center of the stripping body, and a guide rod is fixedly connected to the middle position of the bottom of the inner side of the cutting groove. The guide rod can block and limit the movement with the wire-pulling teeth, and the eccentric shaft meshes with the wire-pulling teeth and the cutting groove.
[0013] Preferably, a support frame is inserted at the front end of the machine tool main frame, and two small conveyor belts are mounted on the top of the support frame. The surface of the small conveyor belts is provided with equally spaced wire grooves for parallel limiting of the wires, so that the wires are horizontally conveyed backward by the small conveyor belts and fall into the wire holder. The small conveyor belts are mounted above the electric conveyor belts through the support frame so that the wires can fall smoothly from the wire grooves into the wire holder.
[0014] This invention provides a connector soldering device for HDMI data cable production, which has the following advantages: I. This connector welding device for HDMI data cable production, through the setting of two sets of small conveyor belts and two sets of guide components, the symmetrical installation of the bottom structure of the lifting rod, and the structural design of each square slot inner bucket that can hold two connectors in opposite directions, enables the welding device to weld two sets of connectors in one welding action. Furthermore, with the continuous operation of the electric conveyor belt and the small conveyor belt, the welding efficiency of the welding device is increased by 100%.
[0015] II. This connector welding device for HDMI data cable production inserts wires into a cutting groove in a circular array, causing the wires to overlap and adhere to the inner wall of the groove to form a ring of wires. Then, a motor is started, which drives the wire-picking teeth to rotate circumferentially inside the cutting groove via an eccentric shaft. The wire-picking teeth and the cutting groove work together to cut the insulation layer on the surface of the wires, easily removing part of the insulation layer on one end of the wires. This achieves automatic wire stripping, eliminating the need for manual wire stripping, saving on wire and labor costs during the stripping process, and effectively improving the welding efficiency of connectors and wires.
[0016] Third, the connector welding device used in the production of HDMI data cables uses a pressing plate that moves up and down in conjunction with a cable clamp to limit the middle of the wire when the welding head contacts the wire. This prevents the wire from being misaligned on the connector due to the welding head's contact with the wire, ensuring a high yield rate for the wire and connector welding, reducing the defective and scrap rates, and helping to improve the welding quality of the connector production.
[0017] IV. This connector welding device for HDMI data cable production can promptly detect the welding parts through the detection head on the cable tester and promptly alarm the connectors with welding problems. It can promptly provide staff with the means to remove abnormal connectors, preventing them from being mixed into normal finished products and harming the interests of users. It can also automatically assist staff in inspecting the welding quality of connectors, saving manpower and material resources.
[0018] 5. The connector welding device for HDMI data cable production uses a rocker arm that is pushed against the surface of an electric conveyor belt by the elastic extension rod. As the electric conveyor belt moves from front to back, the rocker arm is inserted into the notch. This allows the rocker arm to automatically pry the connector with the welded wires out of the square slot, thus achieving automatic connector picking. Attached Figure Description

The pressing plate 34 is pressed against the cable holder 43 through the double-axis telescopic component 33; a disc frame 36 is installed at the bottom of the lifting rod 32, and two welding parts 35 are installed symmetrically on the end of the disc frame 36 away from the lifting beam 31 to control the opening and closing of the welding head 310; one end of the welding part 35 is connected to the soldering body 39 to control the total amount of solder delivered to the connector through the soldering bath 311, and the welding head 310 is installed at equal intervals on the end of the soldering body 39 away from the lifting beam 31.
[0023] Each solder head 310 has a solder inlet 311 on its side wall, and the solder inlet 311 is connected to the inner side of the upper solder body 39. The solder head 310 is hoisted above the square slot 21 by the cooperation of the disc frame 36, the lifting rod 32 and the lifting beam 31. The detection head 38 is hoisted above another square slot 21 on the rear side of the square slot 21. The detection head 38 can be used to detect the weld of the completed joint. One end of the welded part 35 is connected to a cable tester 37. The end of the cable tester 37 away from the lifting beam 31 is equipped with the detection head 38. The cable tester 37 is used to control the detection head 38 to detect the joint and can sound an alarm for the problematic structure.
[0024] The guide assembly 4 is installed on the main frame 1 of the machine tool and is located on the left and right sides of the electric conveyor belt 2. The guide assembly 4 includes a slide table 41 that is fitted and installed on both sides of the electric conveyor belt 2. A rocker plate 42 is installed on the side of the slide table 41 away from the electric conveyor belt 2 and the rocker plate 42 is not connected to the edge of the slide table 41. The rocker plate 42 is connected to the main frame 1 of the machine tool. Wire clamps 43 are installed at equal intervals on the slide table 41 and the wire clamps 43 can slide back and forth on the slide table 41.
[0025] A folding frame 6 is installed at the front bottom of the machine tool main frame 1. A motor 61 is suspended from the top of the folding frame 6. An eccentric shaft 62 is installed at the bottom of the motor 61. A wire-pulling tooth 63 is installed at the bottom pin of the eccentric shaft 62. A wire stripper 64 is installed below the wire-pulling tooth 63 and is installed directly below the motor 61. A cutting groove 66 is opened in the middle of the top of the wire stripper 64. A guide rod 65 is fixedly connected to the middle of the bottom of the inner side of the cutting groove 66. The guide rod 65 can block and limit the wire-pulling tooth 63. The eccentric shaft 62 is engaged with the wire-pulling tooth 63 through the cooperation of the cutting groove 66.
[0026] A lifting frame 7 is inserted at the front end of the main frame 1 of the machine tool. Two small conveyor belts 8 are mounted on the top of the lifting frame 7. The surface of the small conveyor belts 8 is provided with wire grooves 81 at equal intervals for parallel limiting of the wires, so that the wires are horizontally conveyed backward by the small conveyor belts 8 and fall into the wire holder 43. The small conveyor belts 8 are mounted above the electric conveyor belt 2 through the lifting frame 7 so that the wires fall smoothly from the wire grooves 81 into the wire holder 43.
[0027] In use, the connector is fitted inside the square slot 21, and then the stripped wires are placed side by side in the wire trough 81. Simultaneously, the electric conveyor belt 2 and the wire trough 81 are activated, transferring the wires onto the electric conveyor belt 2. The middle of the wire falls onto the wire clamp 43, with the end of the wire exposing its internal core contacting the welding point of the connector. After being horizontally conveyed backwards for the distance of one square slot 21, the dual-axis telescopic component 33 is activated to press the pressing plate 34 into the middle of the wire clamp 43, positioning the middle of the wire. Then, the lifting rod 32 is activated to push the welding component 35 down to the point where the wire contacts the connector, allowing the wire to... The soldering head 310 is placed against the part to be soldered, and then the solder body 39 controls the molten solder to drip onto the part to be soldered through the solder bath 311. Then, the soldering head 310 is controlled by the soldering part 35 to solder the wire and the connector together. Then, the lifting rod 32 is controlled to rise to a certain height, and the soldered connector is conveyed under the electric conveyor belt 2 to the bottom of the cable tester 37. The lifting rod 32 is lowered to the same height as before, and the detection head 38 is placed against the soldering part to detect the soldering result. When the cable tester 37 does not emit any alarm sound, the previous operation is repeated to realize the continuous soldering of the connector by the soldering device.
[0028] The timely detection of the welded parts by the detection head 38 on the cable tester 37, and the timely alarm for the joints with welding problems, can promptly enable the staff to remove the abnormal joints, so as to avoid mixing them with normal finished products and harming the interests of users. It can also automatically assist the staff in inspecting the welding quality of the joints, saving manpower and material resources.
[0029] By pressing the plate 34 in conjunction with the wire clamp 43 to limit the middle of the wire under the rising and falling movement of the dual-axis telescopic component 33, the wire can be prevented from being misaligned on the connector when the welding head 310 contacts the wire. This ensures the good yield of the wire and connector welding, reduces the defective and scrap rates, and helps improve the production welding quality of the connector.
[0030] Before welding, the wires can be inserted into the groove 66 in a circular array, so that one ring of wires fits into the inner wall of the groove 66, while the wires not inserted into the groove 66 overlap the outer side of the stripper. Then, the motor 61 is started, which drives the wire-picking teeth 63 to rotate circumferentially inside the groove 66 via the eccentric shaft 62. The wire-picking teeth 63 and the groove 66 work together to cut the insulation layer on the surface of the wire, which can easily remove part of the insulation layer on one end of the wire, realizing the automatic wire stripping function. There is no need for manual wire stripping, saving the cost of wires lost in the stripping process and labor costs, and effectively improving the welding efficiency of the joint and the wire.
[0031] By setting up two sets of small conveyor belts 8 and two sets of guide components 4, symmetrically installing the bottom structure of the lifting rod 32, and designing the structure that allows two joints to be mounted on the inner side of each square slot 21, the welding device can perform welding processing on two sets of joints after one welding action. Furthermore, with the continuous operation of the electric conveyor belt 2 and the small conveyor belt 8, the welding efficiency of the welding device is doubled.
[0032] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 6 As shown, a guardrail frame 5 is installed at the rear end of the machine tool main frame 1. An elastic horizontal plate 51 is connected to the middle of the guardrail frame 5, and the elastic horizontal plate 51 is located at the center of the rear end of the electric conveyor belt 2. A spring-loaded telescopic rod 52 is inserted into the middle of the side of the elastic horizontal plate 51 facing the electric conveyor belt 2, and the spring-loaded telescopic rod 52 can spring and extend on the elastic horizontal plate 51. A rocker bar 53 is connected to the end of the spring-loaded telescopic rod 52 near the electric conveyor belt 2, and the rocker bar 53 can be fitted to the surface of the electric conveyor belt 2. Under the spring-loaded pushing of the spring-loaded telescopic rod 52, the end of the rocker bar 53 near the electric conveyor belt 2 can be inserted into the notch 22 opened on the side of the square slot 21.
[0033] In use, the rocker bar 53 is pushed and pressed by the spring-loaded telescopic rod 52, and it can be inserted into the notch 22 in accordance with the forward and backward transmission of the electric conveyor belt 2. Thus, the rocker bar 53 can be used to automatically pry out the joint of the welded wire from the square slot 21, realizing the automatic material picking function of the joint.
