The conveying module 100 includes a platform 110, on which a frame 130 is fixedly mounted. The pressing module 400 is mounted on the frame 130. A set of bending modules 300 is mounted on each side of the frame 130, with the two bending modules 300 arranged symmetrically with respect to the pressing module 400. The carrying module 200 is movably mounted on the conveying module 100, and the conveying module 100 can drive the carrying module 200 to perform linear motion. The carrying module 200 includes... The device includes a support platform 210, a clamp 220, and a positioning module 230. A lifting cylinder 211 is fixedly installed on the support platform 210.

A clamping module 400 is used to clamp the ribbon cable, and a bending module 300 is used to bend the ribbon cable.

[0020] During operation, the conveying module 100 transports the carrying module 200 to the loading station. The loading robot places the cable onto the fixture 220. The positioning cylinder 231 in the positioning module 230 drives the movable frame 240 and the movable plate 250 to clamp and position the cable.

The pressing module 400 descends to press the cable, the positioning module 230 releases the cable, the lifting cylinder 211 retracts, the fixture 220 descends, and the two bending modules 300 simultaneously act on the cable to bend it, completing the automatic two-bending process of the cable. The bending module 300 and the pressing module 400 release the cable, the lifting cylinder 211 extends, the fixture 220 rises, and finally, the conveying module 100 transports the bent cable to the unloading station, where the unloading robot removes the cable.

[0021] like Figure 1-2 As shown, a lead screw module 120 is fixedly mounted on the platform 110, and a slide table 121 is mounted on the lead screw module 120. The lead screw module 120 can drive the slide table 121 to slide horizontally. The bearing module 200 is fixedly mounted on the slide table 121. The clamping module 400 is vertically mounted on the frame 130, and the bending module 300 is obliquely mounted on the frame 130. The lead screw module 120 is horizontally mounted on the platform 110. The lead screw module 120 drives the slide table 121 to slide horizontally so that the bearing module 200 on the slide table 121 is located in different positions, such as the loading position, bending position, and unloading position. The frame 130 is used to support the bending module 300 and the clamping module 400. The two sets of bending modules 300 are obliquely and symmetrically mounted on the frame 130 on both sides of the clamping module 400. Optionally, the angle formed between the direction of movement of the bending module 300 and the direction of movement of the pressing module 400 is an acute angle.

[0022] In one possible implementation, such as Figure 9 As shown, the bending equipment is equipped with four sets of wire bending mechanisms.

[0023] like Figure 4 and Figure 8 As shown, a pressure display 131 is fixedly mounted on the frame 130, and a buffer 212 is mounted on the support platform 210. The buffer 212 is used to cushion the clamp 220. The buffer 212 can be a standard hydraulic buffer, used to provide a certain cushioning function to the clamp 220 as it moves up and down under the action of the lifting cylinder 211, thus protecting the clamp 220 from damage. The pressure display 131 is used to display the pressure of the bending module 300 in real time.

[0024] like Figure 3-7 As shown, the clamp 220 includes a base plate 221 and a cover plate 222 fixedly fitted to the base plate 221. A receiving cavity is formed between the base plate 221 and the cover plate 222. The movable frame 240 and the movable plate 250 are installed in the receiving cavity. The cover plate 222 is provided with a fixing positioning pin 223, and a sliding groove 224 and an adsorption groove are formed on the cover plate 222. The adsorption groove is connected to a vacuum device for adsorbing and holding the ribbon cable. The ribbon cable is placed on the cover plate 222. After the movable frame 240 and the movable plate 250 position the ribbon cable, the vacuum device is turned on to adsorb and fix the ribbon cable through the adsorption groove.

[0025] like Figure 4 and Figure 6As shown, a push plate 232 is fixedly mounted on the piston rod of the positioning cylinder 231. The push plate 232 has a groove 233, and the movable frame 240 has a protrusion 244. The protrusion 244 is inserted into the groove 233. The positioning cylinder 231 acts on the movable frame 240 through the push plate 232, causing the movable frame 240 to move along a first horizontal direction. During this movement, the movable frame 240 drives the movable plate 250 to move along a second horizontal direction. The first horizontal direction and the second horizontal direction are not parallel. Optionally, the first horizontal direction and the second horizontal direction are perpendicular to each other. Figure 6 As shown, the first horizontal direction is the X-axis direction, and the second horizontal direction is the Y-axis direction. The positioning cylinder 231 is horizontally mounted on one side of the fixture 220. When the piston rod of the positioning cylinder 231 extends, it acts on the push plate 232. The push plate 232 drives the movable frame 240 to move along the X-axis direction, and the movable frame 240 acts on the movable plate 250, causing the movable plate 250 to move along the Y-axis direction.

Figure 5 As shown, the slide 224 is oblong, and the cover plate 222 is provided with multiple fixed positioning pins 223. Fixed positioning pins 223 are provided near the first movable positioning pin 247 and the second movable positioning pin 252. The cable is placed between the first movable positioning pin 247 and the fixed positioning pin 223, and between the second movable positioning pin 252 and the fixed positioning pin 223. When the piston rod of the positioning cylinder 231 extends, the first movable positioning pin 247 and the second movable positioning pin 252 move toward the nearby fixed positioning pin 223, thereby clamping and positioning the cable.

[0027] like Figure 6-7As shown, the movable frame 240 is provided with a first inclined surface 243, and the movable plate 250 is provided with a second inclined surface 251. When the movable frame 240 moves, the first inclined surface 243 can act on the second inclined surface 251 to make the movable plate 250 move synchronously. An elastic element 253 is provided between the movable plate 250 and the clamp 220. The elastic element 253 is used for the reset of the movable plate 250. When the movable frame 240 moves along the X-axis, the first inclined surface 243 acts on the second inclined surface 251, thereby giving the movable plate 250 a component force along the Y-axis, causing the movable plate 250 to move along the Y-axis. The elastic element 253 is compressed. When the movable frame 240 resets, the movable plate 250 also resets under the action of the elastic element 253.

[0028] like Figure 6-7 As shown, the movable frame 240 includes a first connecting rod 241, a second connecting rod 245, and a clamping block 246.

[0029] like Figure 3 and Figure 8 As shown, the bending module 300 includes a bending cylinder 310. An upper bending blade 320 is connected to the piston rod of the bending cylinder 310, and a lower bending blade 260 is fixedly mounted on the clamp 220.

The lower bending blade 260 has a bending groove 261, and the upper bending blade 320 has a protrusion 321. The protrusion 321 acts on the cable, causing the cable to bend towards the bending groove 261, thus completing the bending operation. The bending cylinder 310 can drive the upper bending blade 320 to move up and down. The pressure sensor 330 is electrically connected to a pressure display 131, which monitors the pressure applied to the cable by the upper bending blade 320 in real time.

A connecting plate 420 is fixedly mounted on the piston rod of the clamping cylinder 410, and a pressure block 430 is fixedly mounted on the connecting plate 420. The clamping cylinder 410 can drive the pressure block 430 to clamp the ribbon cable. The clamping cylinder 410 can drive the pressure block 430 to move up and down to clamp or release the ribbon cable.

[0031] The operation process of this application includes the following steps: Step 1: The conveyor module 100 drives the carrier module 200 to the loading station, and the loading robot moves the cable onto the fixture 220; Step 2: The positioning cylinder 231 extends, and the cable is clamped and positioned by the first movable positioning pin 247 on the movable frame 240 and the second movable positioning pin 252 on the movable plate 250. The cable is then fixed by vacuum adsorption. Step 3: Use CCD camera to check if the cable is properly positioned. If the cable is not properly positioned, the conveyor module 100 will move the cable to the unloading station for unloading. If the cable is properly positioned, the conveyor module 100 will move the cable to the bending station. Step 4: The clamping cylinder 410 extends, driving the pressure block 430 to press the cable, the positioning cylinder 231 retracts, the first movable positioning pin 247 and the second movable positioning pin 252 release the cable, and the vacuum equipment is turned off. Step 5: Lifting cylinder 211 retracts, clamp 220 descends, and two bending cylinders 310 simultaneously drive the upper bending knife 320 to tilt downwards and press down on the bending cable and maintain pressure, forming two bends on the cable. Step 6: The bending cylinder 310 drives the upper bending blade 320 to tilt upwards, the upper bending blade 320 releases the cable, and the clamping cylinder 410 moves upwards to release the cable; Step 7: The conveyor module 100 drives the carrier module 200 to the unloading station, and the unloading robot moves the bent cable into the pallet.
