Description

Technical Field

[0001] The invention belongs to the technical field of automatic feeding, and in particular is an automatic feeding device for battery cable welding. Background Art

[0002] In recent years, with the continuous development and progress of the electronics industry, the demand and standards for battery assembly have also increased. The impact of high-level battery assembly production lines on the consistency of battery assembly products has become increasingly obvious, and rapid battery production is an inevitable trend.

[0003] Different electronic products use batteries of different sizes, and batteries of different sizes need to match corresponding cables. The processing of "tabs" and "cables" is one of the key steps. Tabs refer to the parts at both ends of the battery used to connect to the external circuit, while cables refer to the flexible circuit boards used to connect different electronic components.

[0004] The traditional welding method is to manually press the tabs and the wiring together, and then use welding tools to weld them. However, this welding method is inefficient, and in the process of manually pressing the tabs and the wiring together and welding them, the wiring and the tabs are easily displaced. When performing large-scale welding, it is difficult to ensure welding consistency. Therefore, there is an automated welding equipment on the market to achieve welding of batteries and tabs.

[0005] However, this type of welding equipment is not automatic. Since the tabs are fixed on the cables, the jig cannot adapt to cables of different sizes. Different jigs are required for cables of different sizes. In addition, the cables need to be placed on the jig one by one manually, and then placed in the welding device for the next step. The degree of automation is not high. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Please refer to Figure 1-10 ;

[0037] An automatic feeding device for battery cable welding, comprising a rotating conveying device 1, a discharging device 2, a mobile conveying device 3 and a mobile conveying device 4. Specifically, the rotating conveying device 1 has a plurality of clamping components 11 in a circular array, the clamping components 11 are used to place batteries of different sizes, and one end of the plurality of clamping components 11 is provided with an extension part 13, and the extension part 13 is provided with a pressing component 12 for pressing the cable and the battery tab;

[0038] The discharge device 2 includes a discharge assembly 5, on which a plurality of fixed discharge blocks 23 and movable discharge blocks 29 are installed at intervals. Preferably, the present invention has two fixed discharge blocks 23 and two movable discharge blocks 29, and the fixed discharge blocks 23 and the movable discharge blocks 29 are respectively provided with a slot 1 231 and a slot 233 on opposite sides of the fixed discharge block 23 and the movable discharge block 29. Preferably, an upward extension 232 is provided on the opposite side of the slot 1 231, and the slot 233 is arranged on the extension 232. The fixed discharge block 23 and the movable discharge block 29 of the present invention are mirror-imaged, and have the same structure. The fixed discharge block 23 and the movable discharge block 29 are placed on two adjacent discharge blocks. The cables in slot one 231 and slot two 233 are also placed in a mirror image. The slot widths of slot one 231 and slot two 233 are slightly larger than the width of the cables, so that the cables can be easily put in and pulled out. The movable discharge block 29 is fixed to the discharge assembly 5 by a locking screw 24. A screw locking assembly 25 for rotating the locking screw 24 is provided below the discharge assembly 5. The screw locking assembly 25 is used to tighten and loosen the locking screw 24. A movable adjustment assembly 26 for adjusting the movable discharge block 29 is provided above the discharge assembly 5. It is explained here that the cables welded to the battery tabs in the present invention are independent of each other and are placed in slots one and two, respectively. In slot two, when it is necessary to weld batteries of different models, the distance between the two cables adapted thereto is also different. It is only necessary to adjust the movable discharge block 29 to achieve the distance between the two cables being placed closer or farther. Specifically, the screw locking component 25 loosens the locking screw 24 to release its fixation on the movable discharge block 29, and the movable adjustment component 26 moves the movable discharge block 29. After the movable discharge block 29 is moved into place, the screw locking component 25 tightens the locking screw 24. The mobile conveying device 3 is provided with a clamping component 32, which is used to clamp the two cables to the two discharge blocks at the same time. The mobile conveying device 3 is provided with a clamping component 32, and the clamping component 32 is used to clamp the two cables to the two discharge blocks at the same time. A clamping component 2 is provided on the feeding device 2 4, and the clamping component 2 is used to clamp the two wiring harnesses to the position of the pressing component 12 of the battery mounting fixture 111 at the same time, and press the wiring harnesses to the two pole ears of the battery through the pressing component 12. Specifically, the fixed discharge block 23 of the present invention is marked as A, and the movable discharge block 29 is marked as B. The arrangement order of the fixed discharge block 23 and the movable discharge block 29 is A, B, A, B. When the clamping component 1 32 and the clamping component 2 clamp the wiring harnesses, they clamp the wiring harnesses on the A and B discharge blocks at the same time. If the wiring harnesses of the B and A discharge blocks are clamped at the same time, the two wiring harnesses cannot be aligned with the two pole ears of the battery.

[0039] Adjustment steps: input the battery data to be processed into the control system. After the control system matches the battery cable, loosen the locking screw 24 appropriately through the screw locking component 25. After the locking screw 24 is loosened, the movable adjustment component 26 will clamp and move the two movable discharge blocks 29 from left to right in sequence. For example, when the first movable discharge block 29 moves to the set position, the screw locking component 25 tightens the locking screw 24, and the movable adjustment mechanism 26 releases the first movable discharge block 29, and then moves to the second movable discharge block, and clamps and moves the second movable discharge block to the set position, and then the screw locking component 25 tightens the locking screw 24, adjusts the distance between the fixed discharge block and the movable discharge block, so that the distance between the two cables is adapted to the position of the battery ear, and after the locking screw 24 is tightened, the movable adjustment component 26 is removed, and then the loading and pressing step is performed;

[0040] Loading and pressing steps: the control system controls the mobile conveying device 13 to operate at high speed, and the device for placing the cables from the outside simultaneously clamps two cables matching the battery onto two discharge blocks through the clamping component 132. The operator places the battery in the clamping component 11. After the battery is installed, the operator controls the rotating conveying device 1 to rotate and turn the battery to the cable pressing station. Subsequently, the control system controls the mobile conveying device 24 to clamp the two cables from the two discharge blocks onto the pressing component 12 through the clamping component 2, and make the bottom ends of the two cables contact the two battery tabs. The pressing mechanism simultaneously presses the two cables against the two battery tabs. After the pressing is completed, the rotating conveying device 1 continues to rotate;

[0041] If the spacing between the battery tabs changes, it is necessary to repeat the adjustment step; if the spacing between the battery tabs does not change, the loading and pressing step can be repeated without adjusting the movable discharge block 29.

[0042] In addition, visual detection cameras are provided on the mobile conveying device 1 3 and the mobile conveying device 2 4 for detecting each other's position and movement direction. When the two mobile conveying devices move toward the discharge component 5 at the same time, the mobile conveying device 2 4 stops until the mobile conveying device 1 3 moves away from the discharge component 5, and the mobile conveying device 2 continues to operate to avoid collision between the two mobile conveying devices.

[0043] In this embodiment, the clamping assembly 11 includes a battery mounting jig 111, and a fixing part 112 is provided on one side of the battery mounting jig 111, and a limiting groove 113 connected to the rotating conveying device 1 is provided on the other side. A sliding part 114 is provided on the limiting groove 113, and an adjustment hole 115 is provided on the sliding part 114. The sliding part 114 is connected to the battery mounting jig 111 by using a screw to pass through the adjustment hole 115. The length of the limiting groove 113 is greater than the length of the sliding part 114. After loosening the screw, the sliding part 114 can move freely along the limiting groove 113 to adjust the distance between the sliding part 114 and the fixing part 112, so that batteries of different sizes can be fixed.

[0044] In this embodiment, the pressing assembly 12 includes two symmetrically arranged positioning blocks 121, and the two positioning blocks 121 are provided with adjustment holes 122. The two positioning blocks 121 are connected to the battery mounting fixture 111 by using screws to pass through the adjustment holes 122. By loosening the screws, the positions of the two positioning blocks 121 can be adjusted according to the spacing between the battery ears. A clearance position 123 is provided above the two positioning blocks 121, and the clearance position 123 is used for the extension of the battery ears. A concave step 124 is provided on the side of the positioning block 121 away from the battery mounting fixture 111, and the end of the battery ear is bent at the position of the concave step 124.

[0045] In addition, the pressing assembly 12 also includes a cylinder 125, and the output end of the cylinder 125 is fixedly connected to a fixing part 2 126 in the shape of an "I" character, and a clamping part 127 is installed on the fixing part 126. The fixing part 126 is provided with an adjusting hole 3 128. The clamping part 127 is connected to the adjusting hole 3 128 by using a screw to pass through the side wall of the clamping part 127. The position of the clamping part 127 can be adjusted by loosening the screw to ensure that the adjusted battery ear and cable can be clamped. The clamping part 127 is provided with a pressing portion 129 corresponding to the concave step 124, and the bent part of the ear is pressed and fixed to the cable through the pressing portion 129.

[0046] Specifically, according to the spacing of the battery lugs, the screws fixing the positioning block 121 and the clamping piece 127 are loosened, and the distance between the two positioning blocks 121 and the position of the clamping piece 127 are adjusted to adapt to the battery lugs with different spacings. The battery lugs extend from the avoidance position 123 of the positioning block 121 and are manually bent at the concave step 124. Then, the mobile conveying device 2 4 is used to transport the wiring harness to the bending position of the lug, and the wiring harness is abutted against the bending part of the battery lug. Finally, the cylinder 125 is retracted so that the pressing part 129 presses the bending part of the battery lug and its corresponding wiring harness on the concave step 124, thereby completing the fixation of the lug and the wiring harness.

[0047] In this embodiment, the mobile conveying device 13 and the mobile conveying device 24 have the same structure, but in order to prevent collision accidents caused by operational errors, the two are installed in a horizontally offset manner, which can give the operator a certain reaction time. The mobile conveying device 13 and the mobile conveying device 24 both include a multi-axis moving component 131. The multi-axis moving component 131 is a common device in the field of mechanisms and can adopt a variety of structural forms. The most common multi-axis moving component is a structure in which a motor drives a lead screw and can be matched with a slider guide group. Preferably, the multi-axis moving component 131 of this embodiment is an XYZ three-axis moving component, and the movement of each axis is achieved by a stepper motor driving a lead screw. The multi-axis moving component 131 is provided with a clamping component 132 for clamping the cable arrangement, which is specifically used for clamping the cable arrangement. This design not only improves the degree of automation, but also improves the operating efficiency and reliability of the production line.

[0048] In this embodiment, the discharge assembly 5 includes a support frame 21, and the inner side wall of the support frame 21 is symmetrically provided with a card slot 211, and a cable placement fixture 22 is installed through the two card slots 211. The cable placement fixture 22 is installed on the support frame 21 by insertion, and its outer wall is tightly fitted with the inner wall of the card slot 211 to ensure the stability of the cable placement fixture 22 when used; at least two adjustment holes 221 are arranged in parallel at the bottom of the clamping fixture, and the adjustment holes 221 are cross-staggered with the discharge block. The locking screw 24 passes through the adjustment hole 221 and is threadedly connected to the discharge block, preferably In the present invention, there are two adjusting holes four 221, and the two adjusting holes four 221 correspond to the two ends of the discharge block respectively. The two ends of the discharge block 23 are fixed by the locking screws 24, so that the discharge block will not shift when in use. When the discharge block is used to place cables with different spacings, the locking screws 24 of the movable discharge block 29 are loosened by the screw locking assembly 25, and then the movable discharge block 29 is adjusted along the adjusting holes four 221, so that the spacing between adjacent movable discharge blocks 29 and the fixed discharge block 23 corresponds to the spacing between the two tabs of the battery, and there is no need to equip a special mold, thereby reducing costs.

[0049] In addition, a placement piece matching the spacing between the tabs of a conventional battery is installed between the adjacent movable discharge blocks 29 and the fixed discharge blocks 23. The placement piece is directly placed between two adjacent discharge blocks. The placement piece has a variety of different specifications and sizes and is specially used for batteries of conventional sizes. If conventional batteries are used, the placement piece can be directly installed between two adjacent discharge blocks to directly adjust the spacing between the two discharge blocks, thereby reducing the setting of equipment parameters and improving work efficiency.

[0050] Since the cable placement jig 22 of the present invention is installed on the support frame 21 in a sliding insertion manner, so that one end of the cable placement jig 22 is not fixed, a limit assembly 27 for limiting the movement of the cable placement jig 22 is provided on the outside of the support frame 21, and the limit assembly 27 includes a cylinder 271, and the output ends of the two cylinders 271 are fixedly connected with plug blocks 272. Plug holes 212 are provided on both sides of the support frame 21, and the plug blocks 272 are inserted into the support frame 21 along the plug holes 212 and abut against the outer wall of the cable placement jig 22. When the cable placement jig 22 is inserted, the cylinder 271 pushes the plug block 272 toward the inside of the support frame 21, and after insertion, it abuts against the outer wall of the cable placement jig 22, and cooperates with the support frame 21 to stabilize the cable placement jig 22 from different angles, effectively preventing it from being operated. There is no swing or movement during the process. When the cable placement fixture 22 needs to be replaced, it is only necessary to control the cylinder 271 to reset. When the cylinder 271 is reset, it drives the plug block 272 to move backward toward the outside of the support frame 21. At this time, the cable placement fixture 22 can be pulled out, and then other cable placement fixtures 22 can be replaced. In addition, the end of the plug block 272 inserted into the support frame 21 moves into the socket 212 and then stops moving. In this way, there is no need to calibrate whether the plug block 272 can be inserted into the socket 212 next time. If the plug block 272 leaves the socket 212, the next time the cylinder 271 is started to insert the socket 212 into the socket 212, calibration is required. Otherwise, it is easy to be unable to be inserted into the socket 212 due to deformation of the parts due to long-term use and other situations, resulting in the plug block 272 directly hitting the support frame 21 and damaging the support frame 21.

[0051] In this embodiment, the screw locking component 25 includes a multi-axis moving component 251. The structure of the multi-axis moving component 251 is the same as that of the multi-axis moving component 1 31. It is an XYZ three-axis moving component, and the movement of each axis is achieved by driving the screw rod with a stepping motor. An electric screwdriver 252 is installed on the multi-axis moving component, and a screwdriver head 253 is installed on the electric screwdriver 252. The screwdriver head 253 is used to rotate the locking screw 24 to release the locking fixation of the locking screw 24 on the movable discharge block 29. For example, the locking screw 24 has 15 turns, and the screwdriver head only needs to be screwed about 5 turns. There is no need to unscrew the locking screw 24. It is only necessary for the movable discharge block 29 to move normally. A CCD visual camera 254 is provided on one side of the electric screwdriver 252. The locking screw 24 is photographed and identified by the visual camera, and then the screwdriver head 253 locks or unlocks each locking screw 24. The CCD visual camera 254 will take a photo for retention after the screwdriver head 253 locks or unlocks a locking screw 24.

[0052] In this embodiment, the movable adjustment component 26 includes a multi-axis movable component three 261, and the multi-axis movable component three 261 is provided with a clamping component three 262 for clamping the movable discharge block 29. Preferably, the clamping component three can be a clamping arm that directly clamps the movable discharge block 29 for movement, or it can be a suction nozzle that absorbs the upper surface of the movable discharge block 29 and then moves it. There is no limitation here. A CCD visual camera is also set on the clamping component three 262 for recording the fixed discharge block 23 and the movable discharge block 29.

[0053] Specifically, the mobile adjustment component 26 uses a CCD visual camera to take photos and record the fixed discharge block 23 and the mobile discharge block 29, and the screw locking component 25 uses a CCD visual camera to take photos and record the locking screw 24. After taking photos, the CCD visual camera of the mobile adjustment component transmits the parameters to the control system, and the control system compares the parameters taken by the CCD visual camera with the set parameters. For example, the fixed discharge block 23 and the mobile discharge block 29 set in sequence are a group of discharge blocks, and the fixed discharge block 23 and the mobile discharge block 29 originally set in the system are a group of discharge blocks. The spacing between the movable discharge blocks 29 is 4 cm, while the spacing between the two tabs of the battery after replacing other specifications is 5 cm, so the movable discharge block 29 needs to be moved 1 cm, and the system is set to move the movable discharge block 29 1 cm away from the fixed discharge block 23, so that the spacing between the fixed discharge block 23 and the movable discharge block 29 is 5 cm, and the screw locking component 25 moves to the bottom of the first locking screw 24, and the CCD visual camera takes a picture, and then the screw locking component 25 moves up until the screw head 253 is aligned with the locking screw 24. The screw locking assembly 25 is abutted against the mouth of the movable feeding block 29, and the screw head 253 is rotated to loosen the locking screw 24. After loosening, the screw locking assembly 25 moves down, and the CCD visual camera takes a photo and records. Then, the above steps are repeated to loosen another locking screw 24 of the same movable feeding block 29 and take a photo and record. After loosening, the screw locking assembly 25 moves down, and then the moving adjustment assembly 26 moves, and the clamping assembly three 262 clamps the movable feeding block 29, and moves the movable feeding block 29 away from the fixed feeding block 23 by 1 cm, thereby increasing the spacing between the movable feeding block 29 and the fixed feeding block 23. Adjust to 5cm, after adjustment, move the CCD visual camera of the adjustment component 26 to take pictures and record, then move the screw locking component 25 to the bottom of the first locking screw 24, the CCD visual camera takes pictures, then the screw locking component 25 moves up until the screw bit 253 abuts against the mouth of the locking screw 24, the screw bit 253 rotates to tighten the locking screw 24, after tightening, the screw locking component 25 moves down, the CCD visual camera takes pictures and records, then repeat the above steps to tighten another locking screw 24 of the same movable feeding block 29 and take pictures and record. After adjusting the first movable feeding block 29, the screw locking component 25 moves down and moves to the bottom of the second movable feeding block 29, repeat the above steps of adjusting the first movable feeding block 29 to complete the adjustment of the second movable feeding block 29, then move the CCD visual cameras of the adjustment component 26 and the screw locking component 25 to take pictures and record for subsequent adjustment.
