Description

Technical Field

[0001] The invention relates to the field of cable transportation, and in particular discloses a guiding and conveying device for cable processing. Background Art

[0002] The processing flow of cable plugs involves the following steps: removing the insulating protective layer from the end of the cable cut to the target length, inserting the exposed wire end of the cable into the processing table, using a crimping device to crimp the terminal onto the wire, installing a fixing frame to stabilize the terminal on the wire, and completing the installation of the cable terminal. With the development of science and technology, the processing flow of cables has become more mechanized. The above processing flow can already use the existing assembly line processing equipment to process the cables. After the installation of the terminals is completed, this part of the cable needs to be sent to the packaging device to wrap the insulating material at the wire end with the terminal crimped.

[0003] Since the processing position of the above-mentioned processing device is mainly used to process the end of the cable line, in the assembly line processing process, the end of the cable line is the main moving body, so the cable body is dragged by the end of the cable line, and due to the friction, the cable body cannot move at the same speed as the end of the cable line during the dragging process, so that two or even several adjacent cables are interlaced, resulting in the end of the cable line being separated from the processing device for unified collection after the processing is completed, and this part of the cable line is still in an overlapping state, and as the cables are continuously stacked, the degree of interlacing between the cables increases sharply. Before the subsequent process of wrapping the end of each cable line with insulating material independently, it is necessary to increase the manual work to separate and arrange the cables, resulting in the processing efficiency of the cables being affected.

When the servo motor 203 is started, the synchronous belt 202 is rotated with an intermittent stop, the upper segment of the synchronous belt 202 moves backward, and the lower segment moves forward, and the two transmission wheels 204 are reduced in speed.

[0032] See also Figure 1 , Figure 2 , Figure 4 and Figure 6 , including: a wire loading drum 3 installed on the transport component 2, the wire loading drum 3 consists of two half-drums 301, one of the half-drums 301 is fixed between two synchronous belts 202, the half-drum 301 is perpendicular to the synchronous belt 202, and the other half-drum 301 is rotatably installed on the half-drum 301, there are fourteen such wire loading drums 3, which are evenly arranged on the synchronous belt 202, the cable wire that has completed the end processing will be loaded in the wire loading drum 3, and the transport component 2 starts to move the wire loading drum 3 to transport the cable wire backward.

[0033] See also Figure 3 , Figure 5 and Figure 6 , including: a guide frame 4 installed on the front side of the main frame 1, the guide frame 4 is provided with a guide groove for the cable to pass through and fall, an oblique contact surface is provided on the top of the front side plate of the guide frame 4, the upper space of the guide groove of the guide frame 4 is larger than the lower space of the guide groove, so that the cable can be below the pressing plate 5 and the closing plate 7 after entering the guide frame 4, the spacing of the wire loading drum 3 set on the synchronous belt 202 is matched with the frequency of the intermittent stop of the servo motor 203, so that the wire loading drum 3 is located directly below the guide frame 4 when it stops intermittently; a pressing plate 5 slidably installed on the rear side plate of the guide frame 4, the pressing plate 5 slides downward to press the cable line down; a driving component 6 installed on the guide frame 4, the driving component 6 is connected to the pressing plate 5, and controls the pressing plate 5 to move up and down. The driving assembly 6 includes: a cylinder 601 installed on the rear side of the guide frame 4; a guide rod 602 installed on the guide frame 4, and the pressing plate 5 is slidably installed on the guide rod 602; a connecting rod 603 slidably installed on the guide rod 602, the connecting rod 603 is fixed to the output end of the cylinder 601, and the connecting rod 603 is connected together with the pressing plate 5.

[0034] The conveying device is arranged at the collecting position of the assembly line type processing device of the prior art, and the guide frame 4 will be located below the cable wire unloaded by the processing device, and the servo motor 203 and the cylinder 601 are started. When the cable wire is unloaded, the interlaced part is the wire body of the cable wire, so the end of the cable wire and the wire body near the end thereof will first fall on the oblique contact surface on the front side of the guide frame 4, and slide obliquely backward and downward along the contact surface. The moving path diagram of the cable wire is shown in FIG. Fig.12The cable is then moved to the lower part of the pressing plate 5, and the cable body away from the end is intertwined with the cable body of the subsequent cable being processed. Therefore, when the pressing plate 5 moves downward, the cable is pressed downward to control the cable to be separated from the subsequent cable; thereafter, the cable is guided by the guide frame 4 and can be accurately dropped into the wire loading drum 3, and then transported backward by the wire loading drum 3, so that each cable is transported independently, and after the wire loading drum 3 moves to the rear side of the conveying device, the cable falls from the wire loading drum 3 and is collected uniformly. In the collection state at this time, there is basically no overlap or intertwining between the cable lines, so that the workers who coat the insulating material can take the cable lines for coating processing, that is, the conveying device can not only comb the cables, but also transport the cables to the next processing flow, directly connecting the processing flow of the insulating material coating, making the processing of the cable smoother, simplifying manual operations, reducing unnecessary processing time, and achieving the effect of improving processing efficiency.

[0035] See also Figure 1 , Figure 2 , Figure 7 and Figure 8 , also includes: a closing plate 7 installed on the connecting rod 603; a roller 701 rotatably installed at the bottom of the closing plate 7, and when the closing plate 7 moves down following the connecting rod 603, the roller 701 will contact the outer top of the upper half cylinder 301 of the wire loading barrel 3; an elastic member a8 sleeved on the guide rod 602, the elastic member a8 is specifically a compression spring, and the two ends of the elastic member a8 are respectively fixed on the connecting rod 603 and the pressing plate 5, so that the connecting rod 603 and the pressing plate 5 are movably connected, and the elastic member a8 is slightly deformed by the gravity of the pressing plate 5, and the height position of the pressing plate 5 is lower than the height position of the closing plate 7, and a slot hole for the pressing plate 5 to pass through is opened on the half cylinder 301 of the wire loading barrel 3.

[0036] When the cable enters the guide frame 4, the connecting rod 603 will first move the pressing plate 5 downward through the elastic member a8 to move the cable into the wire loading barrel 3. When the pressing plate 5 moves the cable downward and the cable contacts the bottom of the lower half barrel 301 of the wire loading barrel 3, the closing plate 7 starts to contact the outer top of the upper half barrel 301 of the wire loading barrel 3. The cylinder 601 continues to control the connecting rod 603 to move downward. At this time, the pressing plate 5 is restricted and no longer moves. The elastic member a8 is compressed, and the closing plate 7 continues to move downward, so that the upper half barrel 301 of the wire loading barrel 3 301 rotates downward, and the roller 701 enables the closing plate 7 to smoothly push the upper half cylinder 301 of the wire loading drum 3 to rotate until the upper half cylinder 301 contacts the lower half cylinder 301, closing the wire loading drum 3, so that during the transportation of the cable, the cable is not easy to fall out of the wire loading drum 3, and at this time, the upper half cylinder 301 of the wire loading drum 3 passes through the pressing plate 5; after completion, the air cylinder 601 is controlled to move the connecting rod 603 upward, the pressing plate 5 moves up and resets to leave the slot of the wire loading drum 3, the elastic member a8 is reset, and the closing plate 7 is also moved up and reset.

[0037] See also Figure 1 , Figure 2 , Fig. 9 and Fig.10 , and also includes: an elastic member c10 sleeved on the rotating shafts of the two half-cylinders 301 of the wire loading barrel 3, the elastic member c10 is specifically a torsion spring, the two ends of the elastic member c10 are respectively fixed on the two half-cylinders 301, and the elastic member c10 keeps the two half-cylinders 301 open, and the opening angle is 80 degrees, so that the cable can enter the wire loading barrel 3 along the guide frame 4, and the closing plate 7 can contact with the upper half-cylinder 301; fixed components 9 installed on the left and right sides of the wire loading barrel 3, the fixed components 9 are used to fix the positions of the two half-cylinders 301 after the two half-cylinders 301 are in contact. Taking a single wire loading drum 3 as an example, the fixing assembly 9 includes: slots 905 provided on the left and right sides of the half-drum 301 of the wire loading drum 3 connected to the synchronous belt 202; wedge blocks 902 respectively slidably installed in each slot 905, and the two wedge blocks 902 slide left and right; an elastic member b903 sleeved on the sliding shaft of the wedge block 902, the elastic member b903 is specifically a compression spring, and the two ends of the elastic member b903 are respectively fixed on the wedge block 902 and the half-drum 301 where the wedge block 902 is located; the end of the sliding shaft of the wedge block 902 passes through On the outside of this half cylinder 301, a grooved block b904 is installed on the outer end of the sliding shaft of the wedge block 902, so that the grooved block b904 is slidably installed on the left and right sides of this half cylinder 301; the grooved block a901 installed on the other half cylinder 301, when the two half cylinders 301 are closed, the grooved block a901 will be inserted into the groove 905 and contact with the inclined surface of the wedge block 902, so that the wedge block 902 is clamped in the clamping groove of the grooved block a901, and the elastic member b903 is used to improve the clamping effect between the wedge block 902 and the grooved block a901.

[0038] When the cable is loaded into the wire loading barrel 3 and the closing plate 7 closes the wire loading barrel 3, the grooved block a901 extends into the slot 905 and contacts the wedge block 902. The wedge block 902 is first squeezed to slide away from the half barrel 301 where it is located, that is, slides outward until the wedge block 902 penetrates into the slot of the grooved block a901. The elastic member b903 resets the wedge block 902 and engages the wedge block 902 with the grooved block a901. In this way, the position of the grooved block a901 is limited by the wedge block 902, and the force of the elastic member c10 is overcome, so that the two half barrels 301 remain closed.

[0039] See also Figure 1 , Fig.10 and Fig.11 , and also includes: a detachment plate 11 installed on the left and right sides of the rear of the main frame 1, a contact plate 1101 with gradually increasing thickness is arranged on the rear side of the detachment plate 11, the upper part of the contact plate 1101 is thinner than the lower part thereof, and the rear arc line of the contact plate 1101 is the movement trajectory of the slotted card block b904, so that the contact plate 1101 can extend into the card slot of the slotted card block b904.

[0040] That is, when the loading bobbin 3 is moved and the rear side of the conveying device is flipped, the contact plate 1101 of the disengagement plate 11 is inserted into the slot of the slotted block b904. As the slotted block b904 moves and the contact plate 1101 continues to thicken, the disengagement plate 11 controls the slotted block b904 and the wedge block 902 to slide outward, and the inclined surface of the wedge block 902 squeezes the slotted block a901 and disengages it from the wedge block 902, thereby releasing the fixing effect of the fixing component 9. Therefore, under the reset of the elastic member c10, the two half-cylinders 301 are opened to realize the automatic opening of the loading bobbin 3. When the slotted block b904 moves to disengage from the contact plate 1101, the elastic member b903 resets the wedge block 902 and the slotted block b904, and then the opened loading bobbin 3 moves to the bottom of the guide frame 4 for loading, closing and transporting, and so on.

[0041] Therefore, the fixing component 9 cooperates with the elastic member c10 and the release plate 11 to realize the automatic opening and closing of the wire drum 3. By closing the wire drum 3, the cable can be better transported by the wire drum 3, thereby improving the effect of the wire drum 3 in transporting the cable. In addition, the automatic opening and closing of the wire drum 3 is set, which can ensure that the automation level of the conveying device is not affected, thereby improving the use effect of the conveying device.
