Description

Technical Field

[0001] The present invention relates to the technical field of copper busbar production for new energy motor controllers, in particular to laser cleaning equipment for copper busbars for new energy motor controllers. Background Art

[0002] The copper busbar of the new energy motor controller is composed of an IGBT module and a three-phase current sensor. After the three-phase current sensor is welded to the IGBT module, the copper busbar usually needs to be cleaned to ensure the normal operation of the new energy motor controller.

[0003] When using existing laser cleaning equipment, the laser cleaner is fixed above the copper busbar, and the laser cleaner emits laser to clean from top to bottom. This laser cleaning method can wash away the dust on the copper busbar, but during the cleaning process, the cleaned dust scatters and can easily adhere to the copper busbar again; in addition, since there are twelve contacts on the IGBT module that need to be cleaned, and there are also three connection points on the three-phase current sensor that need to be cleaned, the twelve contacts and three connection points are respectively arranged on the front and back sides of the copper busbar, resulting in the existing laser cleaning equipment needing to be turned over manually or by a robot when in use. The turning process can also easily cause the scattered dust to stick to the copper busbar again, resulting in poor cleaning effect of the copper busbar, seriously affecting the normal use of the new energy motor controller.

The piston rod head of the unloading electric cylinder is arranged perpendicular to the horizontal part of the L-shaped clamp.

[0016] The method for using the laser cleaning equipment for the copper busbar of the new energy motor controller is characterized by comprising the following steps:

[0017] Step 1: Place the copper bar through the box opening onto the limit abutment column in the sealed box. Two material detection sensors detect whether an IGBT module and a three-phase current sensor are placed on the top of the limit abutment column through the flip groove. When the IGBT module and the three-phase current sensor are detected, the piston rod head of the spinning cylinder retracts, pressing the copper bar tightly between the top of the limit abutment column and the spinning block.

[0018] Step 2: The cleaning controller controls the feeding linear motor to drive the sealed box to move and feed the material, and moves the sealed box to the bottom of the shooting module. The piston rod head of the shooting cylinder is extended and retracted to drive the shooting slide to slide along the shooting slide slot, so that the camera on the shooting slide moves back and forth above the two sealed boxes, and shoots the front and back of the copper busbar, and sends the shooting results to the cleaning controller;

[0019] Step 3. After the shooting is completed, the feeding linear motor drives the sealing box to move and feed the material to the bottom of the sealing cover. The sealing cylinder drives the sealing cover to descend to seal the sealing box. The horizontal linear motor drives the horizontal slide to slide horizontally, the vertical linear motor drives the vertical slide to slide longitudinally, and the vertical linear motor drives the laser seat to slide up and down. The position of the laser cleaner is adjusted so that the laser emitted by the laser cleaner passes through the glass plate in the cleaning groove to clean the contacts and connection points on the front of the copper busbar. At the same time, the dust cleaned from the front is extracted through the air inlet pump, air outlet pump, air inlet pipe and air outlet pipe to avoid dust scattering in the sealing box during the cleaning process.

[0020] Step 4. After the front cleaning is completed, the flip electric cylinder drives the flip plate seat to flip 180 degrees through the flip axis, so that the back of the copper busbar faces upward, the horizontal linear motor drives the horizontal slide to slide horizontally, the vertical linear motor drives the vertical slide to slide longitudinally, and the vertical linear motor drives the laser seat to slide up and down. The position of the laser cleaner is adjusted so that the laser emitted by the laser cleaner passes through the glass plate in the cleaning groove to clean the contacts and connection points on the back of the copper busbar. At the same time, the dust cleaned from the back side is extracted through the air inlet pump, air outlet pump, air inlet pipe and air outlet pipe to prevent dust from scattering in the sealing box during the cleaning process. After cleaning is completed, the sealing cylinder drives the sealing cover to rise and open the sealing cover again.

[0021] Step 5: The feeding linear motor drives the sealing box to move and feed the material to the bottom of the shooting module. The shooting module takes pictures of the dust on the front and back of the copper busbar again and sends the shooting results to the cleaning controller. The cleaning controller compares the dust conditions before and after cleaning to confirm whether the cleaning is qualified.

[0022] Step 6. After the second shooting is completed, the feeding linear motor drives the sealing box to move and feed the material to the unloading robot, so that the horizontal part of the L-shaped clamping block is under the copper bar, and the double-headed cylinder drives the vertical parts of the two L-shaped clamping blocks to approach each other, gradually clamping the copper bar, and at the same time, the piston rod head of the unloading electric cylinder is extended, and the vertical part of the L-shaped clamping block is pressed against the left and right sides of the copper bar, and the left and right sides of the copper bar are limited. The piston rod head of the unloading electric cylinder is extended to press the copper bar against the horizontal part of the L-shaped clamping block, and the upper and lower sides of the copper bar are limited to clamp the copper bar; if the cleaning is qualified, the unloading robot transfers the copper bar in the sealing box to the unloading machine; if the cleaning is unqualified, the unloading robot transfers the copper bar in the sealing box to the rework rack.

[0023] The beneficial effects of the present invention are:

[0024] 1. When in use, place the copper busbar through the box opening onto the flip fixture in the sealed box. The cleaning controller controls the feeding linear motor to drive the sealed box to move and feed the material. The sealed box is moved directly under the shooting module. The shooting module takes pictures of the dust on the front and back of the copper busbar and sends the shooting results to the cleaning controller.

[0025] Second, after the shooting is completed, the feeding linear motor drives the sealing box to move and feed the material to the sealing assembly. The sealing assembly seals the box opening to make the sealing box sealed. At this time, the electric moving frame drives the laser cleaner to move to clean the front of the copper busbar. At the same time, the dust removed by the cleaning is extracted through the air inlet pump, air outlet pump, air inlet pipe and air outlet pipe to prevent dust from scattering in the sealing box during the cleaning process. After the front cleaning is completed, the flipping fixture drives the copper busbar to turn over and clean the back of the copper busbar.

[0026] 3. After cleaning is completed, the feeding linear motor drives the sealing box to move and feed the material to the bottom of the shooting module. The shooting module takes pictures of the dust on the front and back of the copper busbar again and sends the shooting results to the cleaning controller. The cleaning controller compares the dust conditions before and after cleaning to confirm whether the cleaning is qualified.

[0027] 4. After the second shooting is completed, the feeding linear motor drives the sealed box to move and feed it to the unloading robot. If the cleaning is qualified, the unloading robot transfers the copper busbar in the sealed box to the unloading machine; if the cleaning is unqualified, the unloading robot transfers the copper busbar in the sealed box to the rework rack;

[0028] The present invention can prevent the dust from being scattered and sticking to the copper busbar again during the process of cleaning the dust on the copper busbar, and can clean both sides of the copper busbar without manual flipping or robot flipping, so the cleaning effect is better and the normal use of the new energy motor controller is guaranteed.

[0053] Step 2: The cleaning controller controls the feeding linear motor 2 to drive the sealing box 5 to move and feed, and moves the sealing box 5 to the bottom of the shooting module 7. The piston rod head of the shooting cylinder 702 is extended and retracted to drive the shooting slide 701 to slide along the shooting slide groove, so that the camera on the shooting slide 701 moves back and forth above the two sealing boxes 5, and shoots the front and back sides of the copper busbar 100, and sends the shooting results to the cleaning controller;

[0054] Step 3. After the shooting is completed, the feeding linear motor 2 drives the sealing box 5 to move and feed the material to the bottom of the sealing cover 802. The sealing cylinder 803 drives the sealing cover 802 to descend and seal the sealing box 5. The horizontal linear motor 1102 drives the horizontal slide 1103 to slide horizontally, the vertical linear motor 1104 drives the vertical slide 1105 to slide longitudinally, and the vertical linear motor 1106 drives the laser seat 1107 to slide up and down. The position of the laser cleaner 10 is adjusted so that the laser emitted by the laser cleaner 10 passes through the glass plate in the cleaning groove to clean the contacts and connection points on the front of the copper busbar 100. At the same time, the dust cleaned from the front is sucked away by the air inlet pump, the air outlet pump, the air inlet pipe 601 and the air outlet pipe 602 to prevent dust from scattering in the sealing box 5 during the cleaning process.

[0055] Step 4. After the front cleaning is completed, the flip electric cylinder 1203 drives the flip seat 1201 to flip 180 degrees through the flip shaft 1202, so that the back of the copper busbar 100 faces upward, the horizontal linear motor 1102 drives the horizontal slide 1103 to slide horizontally, the vertical linear motor 1104 drives the vertical slide 1105 to slide longitudinally, and the vertical linear motor 1106 drives the laser seat 1107 to slide up and down, and adjust the position of the laser cleaner 10 so that the laser emitted by the laser cleaner 10 passes through the glass plate in the cleaning groove to clean the contacts and connection points on the back of the copper busbar 100. At the same time, the dust cleaned from the back is extracted through the air inlet pump, the air outlet pump, the air inlet pipe 601 and the air outlet pipe 602 to prevent dust from scattering in the sealing box 5 during the cleaning process; after the cleaning is completed, the sealing cylinder 803 drives the sealing cover 802 to rise, and the sealing cover 802 is opened again;

[0056] Step 5: The feeding linear motor 2 drives the sealing box 5 to move and feed the material to the bottom of the shooting module 7. The shooting module 7 takes pictures of the dust on the front and back of the copper busbar again, and sends the shooting results to the cleaning controller. The cleaning controller compares the dust conditions before and after cleaning to confirm whether the cleaning is qualified;

[0057] After the second shooting is completed, the feeding linear motor 2 drives the sealing box 5 to move and feed the material to the blanking manipulator 9, so that the horizontal part of the L-shaped clamping block 907 is moved down to the bottom of the copper bar 100, and the double-headed cylinder 906 drives the vertical parts of the two L-shaped clamping blocks 907 to approach each other, gradually clamping the copper bar 100. At the same time, the piston rod head of the blanking electric cylinder 905 is extended, and the vertical part of the L-shaped clamping block 907 is pressed against the left and right sides of the copper bar 100, limiting the left and right sides of the copper bar 100, and the piston rod head of the blanking electric cylinder 905 is extended to press the copper bar 100 against the horizontal part of the L-shaped clamping block 907, limiting the upper and lower sides of the copper bar 100, and clamping and fixing the copper bar 100; if the cleaning is qualified, the blanking manipulator 9 transfers the copper bar 100 in the sealing box 5 to the blanking machine 3; if the cleaning is unqualified, the blanking manipulator 9 transfers the copper bar 100 in the sealing box 5 to the rework rack 4.
