Description

Technical Field

[0001] The present invention relates to the technical field of wire welding equipment, and particularly to a wire welding device for a DB connector. Background Art

[0002] During the mechanical production and processing of semiconductor devices, the production of a large number of wire connectors is involved. At present, the mainstream method in the industry is to use manual welding to achieve the welding of wires and connectors. For example, for a DB connector, the welding process is as follows: Arrange the order of each wire in the wire according to the designed order. (1) Peel off the insulation layer of the wire. (2) Slip an insulating sleeve over the wire. (3) Weld each wire in turn. (4) Arrange the insulating outer sleeve sleeved on the wire to protect the exposed metal wire and the welding part. This process is completely completed by manual operation of the welding worker, which requires high welding skills and is difficult to control the welding quality and efficiency. Summary of the Invention

[0003] To overcome the above disadvantages, the purpose of the present invention is to provide a wire welding device for a DB connector, which solves the problems of time-consuming, laborious, low efficiency and low yield of manual welding.

[0004] To achieve the above object, the technical solution adopted by the present invention is: A wire welding device for a DB connector, including an operation platform for placing the DB connector, and a hoisting platform is suspended above the operation platform. One side of the operation platform is provided with a wire platform for arranging wires, and the other side is provided with a tin melting heating device for heating the DB pins of the DB connector. A wire arranging assembly for arranging wires is slidably provided on the wire platform. On the hoisting platform, there are sequentially provided a solder component, a wire cutting component and a wire stripping component that can move independently. The solder component is used for soldering the connector of the DB connector, the wire cutting component is used for cutting the ends of each wire of the wire, and the wire stripping component is used for stripping the wire rubber of the ends of each wire of the wire.

[0005] The beneficial effects of the present invention are as follows: During operation, workers place each wire of the cable into the cable sorting assembly, and the cable sorting assembly sorts each wire of the cable. Then, the end of the wire is cut off by the cable cutting assembly to make the ends of each wire flush. The end of the wire is skinned by the cable skinning assembly to expose the wire core at the end of the wire. Then, the connection head of the DB connector is soldered by the soldering assembly. Next, the wire cores of each wire are docked to the connection head of the DB connector by the movement of the cable sorting assembly. The DB pin is heated by the tin melting heating device, and the heat is transferred to the corresponding DB plug through the DB pin to melt the solder on the DB plug to form a firm weld with the wire core. Through the cooperation of the tin melting heating device, the cable sorting assembly, the cable cutting assembly, the cable skinning assembly, and the soldering assembly, the automatic welding of the DB connector and the cable is realized, avoiding the time-consuming and laborious problem of manual welding, greatly improving the cable welding efficiency of the DB connector, and ensuring the welding quality.

[0006] Furthermore, the cable sorting assembly includes a sorting base. A number of parallel accommodation grooves corresponding to the cables one by one are opened at the upper end of the sorting base. A slot communicating with each accommodation groove is provided at the lower end of each accommodation groove. A guiding member for sorting the cable is jointly arranged in the corresponding slot and accommodation groove.

[0007] Furthermore, the accommodation groove is composed of a first groove and a second groove with a stepped structure. The first groove is located on the side of the second groove close to the operation platform. The groove width of the first groove matches the outer diameter of the insulating sleeve, and the groove width of the second groove matches the outer diameter of the cable. When each wire of the cable is placed into the accommodation groove, the second groove can limit and sort the wire. At the same time, the insulating sleeve can be sleeved onto the wire along the first groove, and the first groove limits the insulating sleeve sleeved onto the wire.

[0008] Furthermore, the guiding member includes a sleeve guiding rod and a wire guiding rod corresponding to the first groove and the second groove respectively. Both the sleeve guiding rod and the wire guiding rod include a rod body slidably arranged in the slot. An air-operated clamping rod forming a Y-shaped structure with the rod body is provided at the upper end of the rod body. The air-operated clamping rod is located in the first groove or the second groove, and a clamping surface capable of holding the insulating sleeve or the cable is provided thereon. The clamping or loosening of the insulating sleeve or the wire is realized through the setting of the air-operated clamping rod. The movement of the rod body drives the air-operated clamping rod to move in the first groove or the second groove, thereby realizing the movement of the insulating sleeve or the wire.

[0009] Furthermore, a stop plate for limiting the movement range of the sleeve guiding rod and the wire guiding rod is provided in the slot at the junction of the first groove and the second groove.

[0010] Furthermore, a double-rail slide is arranged on the cable platform along its length direction, and a slider capable of sliding along the double-rail slide is arranged at the lower end of the sorting base.

[0011] Furthermore, a plurality of guide rail grooves perpendicular to the double-rail slide are arranged at the lower end of the hoisting platform, and the plurality of guide rail grooves respectively correspond to the cable cutting assembly, the cable stripping assembly, and the soldering assembly one by one.

A cable platform 4 for arranging cables is provided on one side of the operation platform 2, and a tin melting heating device 5 for heating the DB pins of the DB connector 1 is provided on the other side. A cable arranging component for arranging cables is slidably provided on the cable platform 4, and a soldering component 6, a cable cutting component 7, and a cable stripping component 8 that can move independently in sequence are provided on the hoisting platform 3. The soldering component 6 is used for soldering the connection head of the DB connector 1, the cable cutting component 7 is used for cutting the ends of the respective wires of the cable, and the cable stripping component 8 is used for stripping the wire rubber skins at the ends of the respective wires of the cable.

[0025] In this embodiment, refer to the attached Figure 2 、 3 As shown, the cable arranging component includes an arranging base 9 slidably provided on the cable platform 4. Specifically, in actual design, double-rail slides 41 can be arranged along the length direction of the cable platform 4, and a slider matching the double-rail slides 41 is fixedly connected to the lower end of the arranging base 9. When the slider moves along the double-rail slides 41, the arranging base 9 can approach or move away from the operation platform 2.

[0026] A plurality of parallel accommodating grooves 91 corresponding to the respective wires of the cable are opened at the upper end of the arranging base 9. A slot 92 communicating with each accommodating groove 91 is provided at the lower end of each accommodating groove 91, and a guiding member for arranging the cable is jointly provided in the corresponding slot 92 and accommodating groove 91.

[0027] Specifically, refer to the attached Figure 3As shown, each of the accommodating grooves 91 is composed of a first groove 911 and a second groove 912 in a stepped structure. The first groove 911 is located on the side of the second groove 912 close to the operation platform 2. The cross-sections of the first groove 911 and the second groove 912 are both semi-circular structures. The groove width of the first groove 911 matches the outer diameter of the insulating sleeve, and the groove width of the second groove 912 matches the outer diameter of the cable. When the conductors of the cable are placed in the accommodating groove 91, the second groove 912 can limit and arrange the conductors. At the same time, the insulating sleeve can be sleeved onto the conductors along the first groove 911, and the first groove 911 limits the insulating sleeve sleeved onto the conductors.

[0028] A slot 92 is jointly provided at the lower ends of the first groove 911 and the second groove 912. The guiding member includes a sleeve guiding rod for guiding the insulating sleeve and a wire guiding rod 93 for guiding the wire. See the appendix Figure 4 As shown, the wire guiding rod 93 includes a rod body 931 that can move along the slot 92 driven by a driving member. The upper end of the rod body 931 is provided with a pneumatic clamping rod 932 that forms a Y-shaped structure with it. The pneumatic clamping rod 932 is located in the second groove 912, and a clamping surface 933 for holding the wire is provided thereon. In use, the wire can be clamped by the opening or clamping of the pneumatic clamping rod 932, and then the wire is driven to move in the second groove 912 by the movement of the rod body 931 in the slot 92. The structure of the sleeve guiding rod is basically the same as that of the wire guiding rod, and the only difference is that the pneumatic clamping rod of the sleeve guiding rod is located in the first groove, and the clamping surface of the sleeve guiding rod is used to hold the insulating sleeve.

[0029] A stop plate for limiting the moving range of the sleeve guiding rod and the wire guiding rod is also provided in the slot 92 at the junction of the first groove 911 and the second groove 912.

[0030] A plurality of guide grooves perpendicular to the double-track slide rail 41 are provided at the lower end of the hoisting platform 3. The plurality of guide grooves correspond to the cable cutting assembly 7, the cable stripping assembly 8, and the soldering assembly 6 respectively to realize the independent movement of each assembly.

[0031] The soldering assembly 6 can adopt a multi-head soldering iron machine in the prior art, and the cable cutting assembly 7 can adopt a pneumatic cutting knife in the prior art. The specific structure thereof will not be elaborated here. See the appendix Figure 2 、 5As shown, the cable stripping assembly 8 includes a stripping base 81 that can move along the corresponding guide groove driven by a driving member. A lifting plate 82 that can move up and down is slidably arranged on the stripping base 81. A stripping blade 83 that can rotate driven by a rotating motor is provided at the lower end of the lifting plate 82. The stripping blade 83 is a semi-circular structure with an inner diameter smaller than the outer diameter of the wire. When stripping is required, the stripping blade 3 is driven by the lifting plate 82 to move downward until the stripping blade 83 abuts against the outer wall of the wire. The stripping blade 83 is driven by the rotating motor to rotate clockwise by 45°. Then, after the stripping blade 83 resets, it rotates counterclockwise by 45°. After the stripping blade 83 resets again, the lifting plate 82 drives the stripping blade 83 to move downward a specified distance (this specified distance is equivalent to the thickness of the wire rubber). Then, in cooperation with the cable sorting assembly, the wire is driven to move, so as to realize the separation of the cut wire rubber from the wire.

[0032] In order to collect the cut wire rubber, a waste recycling device 10 for collecting stripping waste is further provided between the operation platform 2 and the cable platform 4.

[0033] It should be noted that the driving member in this embodiment can be an electric cylinder or a cylinder in the prior art according to actual assembly requirements. The cable cutting assembly can realize the synchronous cutting of each wire of the cable in one operation, while the cable stripping assembly can only realize the stripping operation of a single wire in one operation, and the soldering assembly can also only realize the soldering operation of a single DB connector in one operation.

[0034] A heating base 21 is slidably arranged on the operation platform 2. A plurality of heating plugs 22 corresponding one by one to the DB pins of the DB connector are provided at one end of the heating base 21, and the other end is connected to the tin melting heating device 5. The tin melting heating device 5 is an electric heater.

[0035] The specific working process of this embodiment is as follows: S1. First, the worker places each wire of the cable into each accommodating groove 91 of the sorting base in the designed order in sequence (when placing the wires, the first groove 911 and the second groove 912 of the accommodating groove 91 should be filled); S2. Drive the wire guiding rod 93 through the driving member to drive the wire to move towards the operation platform 2 until one end of the wire partially extends out of the first groove 911, start the cable cutting assembly 7, and perform limit cutting on each wire extending out of the first groove 911 to make the ends of each wire flush, and then the cable cutting assembly 7 resets; S3. Drive the wire guiding rod 93 through the driving member again to drive the wire to move towards the operation platform 2 until one end of the wire extends out of the first groove 911, start the cable stripping assembly 8, and realize the annular cutting of the wire rubber by the stripping blade 83 through the cooperation of the lifting plate 82 and the rotating motor, and then drive the wire guiding rod 93 through the driving member to drive the wire to move away from the operation platform 2 to separate the cut wire rubber from the wire, and then the cable stripping assembly 8 resets, and the cut wire rubber falls into the waste recycling device 10; S4. Drive the cable stripping assembly 8 to move along the guide groove of the hoisting platform 3 until it aligns with another accommodating groove 91; S5. Repeat S3 and S4 until all wires have completed the stripping operation; S6. Drive the wire to move away from the operation platform 2 through the wire guiding rod 93 until one end of the wire is completely placed in the second groove 912; the worker sequentially places the insulating sleeves into the first groove 911, and drives the insulating sleeves to move through the sleeve guiding rod until one end of the insulating sleeve is flush with the end of the first groove 911 close to the operation platform 2; S7. Drive the wire to move towards the operation platform 2 through the wire guiding rod 93 until one end of the exposed wire core passes through the insulating sleeve and partially exposes the insulating sleeve; S8. Move the heating base 21 on the operation platform 2 to make the heating plug 22 plug into the corresponding DB pin, and at this time, the electric heater is not working; S9. Solder the DB connector through the soldering assembly 6, and move the sorting base 9 on the double-track slide rail 41 to make one end of the exposed wire core of the wire correspond to the corresponding DB connector in sequence; S10.
