Description

Technical Field

[0001] The present invention relates to the technical field of paint stripping of circuit board components, and in particular to an inductive laser paint stripping machine for circuit boards used in new energy batteries. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. It has a certain inductance and only blocks changes in current. If no current flows through the inductor, it will try to block the current from flowing through it when the circuit is connected. If current flows through the inductor, it will try to maintain the current when the circuit is disconnected. Inductors can be installed on circuit boards and are widely used in the field of new energy batteries. When manufacturing inductors, copper wire needs to be wound around the blank, and then the enamel layer on the copper wire of the blank after winding is removed to facilitate the subsequent soldering of the electrode pins. Therefore, a laser paint stripper is used.

[0003] The existing laser paint stripping machine for inductors has many technical defects in use. First, the inductors are loaded by manual picking or mechanical grabbing, which is time-consuming and labor-intensive, and inefficient. When the inductors are mechanically grabbed, they are easy to fall off due to their small size and smooth surface. Second, during the process of unloading from the vibration plate and transporting from the belt conveyor, the inductors are easily squeezed and rubbed against each other, or contaminated with workshop dust, causing their surface to easily carry static electricity. The accumulated charge can easily cause safety problems and is not conducive to subsequent laser processing. Third, the powder blown away by the air pipe during laser paint stripping will form dust in the workshop. The existing measure is to use a vacuum cleaner to absorb it in time, but since the amount of dust generated by each group of inductors is very small, the cost of using a vacuum cleaner for a long time is too high, resulting in low energy utilization.

[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose an inductive laser paint stripping machine for circuit boards used in new energy batteries. Summary of the Invention

[0028] The present invention provides an improved inductive laser paint stripping machine for circuit boards used in new energy batteries. Compared with the prior art, it has the following significant improvements and advantages:

[0029] Start the first servo motor, and the first rotating shaft drives the crank to move in a circle. The driving column and the strip groove interact with each other, driving the pusher frame to move linearly to the left in the linear groove first. The pusher rod passes through the pusher port and pushes the inductive workpiece through the pusher port into the loading chamber until the inductive workpiece falls on the first set of unloading plates at the front. Then the pusher frame moves linearly to the right in the linear groove, driving the pusher rod to return to its position. This cycle is repeated to achieve the purpose of automatic pushing.

[0030] Start the second servo motor, and after a series of transmissions, the eccentric column makes a circular motion and enters the closest set of drive slots, pushing the quarter wheel to rotate 90 degrees, and the No. 1 gear is rotated through the rotating rod, so that the long tooth part moves forward in a straight line for a distance, driving the entire mobile loading box to move in a straight line on the driving guide table, so that the second set of unloading channels in the loading chamber is facing the pushing port, and the pushing rod is used to load the material. This is repeated to ensure that the length of each driving guide table movement is equal to the distance between adjacent unloading channels, so as to achieve the purpose of automatic loading.

[0031] Start the third servo motor to drive the No. 2 gear to rotate and drive the gear rod to move linearly, thereby driving the slide to move linearly to the left in the storage slot, so that several groups of unloading plates immediately evacuate the unloading channel position, and the inductive workpieces on the unloading plates move downward along the unloading channel and fall onto the tooling rack directly below the mobile loading box. Several groups of inductive workpieces enter the positioning slots respectively to complete precise unloading. Compared with manual labor, it saves time and labor, and has a lower error rate than mechanical grasping.

[0032] Start the ion blower to generate ion wind which enters the ion air duct and is discharged from several groups of air outlets to blow towards the inductive workpiece directly below. On the one hand, it can neutralize the positive and negative static charges on the outer surface of the inductive workpiece and eliminate static electricity. On the other hand, it can blow away the dust or impurities on the outer surface of the inductive workpiece to achieve the purpose of cleaning.

[0033] The powder will directly enter the collection chamber on one side of the positioning groove with the direct air flow, and will be intercepted by the filter cloth in the collection chamber. The powder will be adsorbed on the filter cloth to achieve the purpose of direct collection. When cleaning, the cylinder is started, and the cylinder rod extends upward, driving the support seat to move upward, so that the guide pipe grooves of several groups of dust collection square tubes on the horizontal tube frame are respectively connected to the dust collection box opening, and the dust collection motor is started to generate a strong suction force on the filter cloth of the dust collection box, so that the dust on the filter cloth flows along the dust collection square tube and the corrugated telescopic tube into the dust collection box and is collected centrally. The dust collection motor only needs to work periodically, thereby solving the technical problems of continuous operation of the vacuum cleaner and low energy utilization rate.

[0071] When using this embodiment, a plurality of inductance workpieces 10 are first placed on the vibration disk of the vibration disk module 11. The vibration disk can neatly transport the inductance workpieces 10 into the straight vibration flow channel through mechanical vibration. The front and back sides of the inductance workpieces 10 are obtained by the visual system, and they are uniformly turned over in sequence until the inductance workpieces 10 are transported to the belt conveyor 12, blocked by the stop block 13, and arranged in sequence on the belt of the belt conveyor 12. At this time, the first servo motor 26 is started, and the first rotating shaft 27 drives the curved The handle 24 makes one circular motion. During this process, the driving column 25 and the strip groove 23 interact with each other, driving the pusher frame 21 to move linearly to the left in the linear groove first, and the pusher rod 22 passes through the pusher port 14, contacts the inductor workpiece 10, and pushes the inductor workpiece 10 through the pusher port 14 into the loading chamber 53 until the inductor workpiece 10 falls on the first group of unloading plates 93 at the front. Then the pusher frame 21 moves linearly to the right in the linear groove, driving the pusher rod 22 to return to its position, completing the loading of a group of inductor workpieces 10.

[0072] Then the second servo motor 33 is started, and the second rotating shaft 34 is used to drive the rotating seat 35 to rotate one circle. During the process of the rotating seat 35 rotating one circle, the eccentric column 38 makes a circular motion and enters the closest set of driving grooves 41, pushing the quarter wheel 40 to rotate 90°, and the No. 1 gear 45 is rotated accordingly through the rotating rod 43. The long tooth portion 52 and the No. 1 gear 45 engage with each other, causing the long tooth portion 52 to move forward in a straight line for a distance (i.e., one-quarter of the circumference of the No. 1 gear 45), driving the entire mobile loading box 50 to move in a straight line on the driving guide platform 30. As a result, the second set of unloading channels 54 in the loading chamber 53 are opposite to the pushing port 14. The above operation is repeated and the pushing rod 22 is used to complete the loading of the second set of inductive workpieces 10. This cycle is repeated until all the unloading plates 93 in the loading chamber 53 have inductive workpieces 10 placed on them.

[0073] At this time, the ion blower is started to generate ion wind that enters the ion wind duct 56 and is discharged from several groups of air outlets 57 to blow towards the inductor workpiece 10 directly below to neutralize the positive and negative static charges on the outer surface of the inductor workpiece 10. Then the third servo motor 97 is started to drive the second gear 96 to rotate and drive the gear rod 95 to move linearly, thereby driving the slide 91 to move linearly to the left in the storage slot, so that several groups of unloading plates 93 immediately evacuate the unloading channel 54 position, so that the inductor workpiece 10 on the unloading plate 93 moves downward along the unloading channel 54 and falls onto the tooling rack 3 directly below the mobile loading box 50. Several groups of inductor workpieces 10 respectively enter the positioning groove 4 to complete precise unloading.

[0074] Then, the tooling frame 3 carrying the inductive workpiece 10 moves straight to the left along the chain plate conveyor 2 and stops under the laser lens module 8. Then, under the traction of the driving module 7, the laser head 5 on the laser lens module 8 is used to perform orderly laser processing on the inductive workpiece 10 in sequence, so that the enamel layer on the copper wire melts and forms cracks after cooling. The powder in the cracks is immediately blown away with an air pipe, leaving the copper wire part to facilitate soldering of the electrode pins. The above operation is repeated for each group of tooling frames 3 on the chain plate conveyor 2 to form a continuous operation. Example 2

[0075] Based on the first embodiment, the powder blown away by the air blow pipe will form dust in the workshop. The existing measure is to use a vacuum cleaner to absorb it. However, since the amount of dust generated by each group of inductor workpieces 10 is very small, the cost of using the vacuum cleaner for a long time is too high, resulting in low energy utilization. In order to solve the above technical problems, we set a dust collection box 60 on the side of each group of positioning grooves 4 away from the air blow pipe, such as Figure 12-15 shown.

[0076] Specifically, the opening of the dust box 60 and the side of the tooling frame 3 are riveted together to play a connecting and fixing role. A collection chamber 61 is opened inside the dust box 60. A layer of filter cloth 62 is laid around the collection chamber 61. Ventilation holes are opened on the inner wall of the collection chamber 61 to assist the filtration of the filter cloth 62. Figure 12 and 13 shown.

[0077] Furthermore, a dust collecting box 63 is fixedly provided inside the machine 1, and the dust collecting box 63 includes a dust collecting motor 64 and a dust collecting bag structure, such as Figure 14 and 15 shown.

[0078] Among them, the upper end surface of the dust collection box 63 is provided with a multi-tube joint 70, and the multi-tube joint 70 is connected to a plurality of groups of bellows telescopic tubes 71. The bellows telescopic tubes 71 can be extended and retracted as the dust collection square tube 72 moves. The upper end of each group of bellows telescopic tubes 71 is sealed and connected to the dust collection square tube 72. The right side of the receiving trough 80 is provided with a guide tube groove for extending the plurality of groups of dust collection square tubes 72. The dust collection square tube 72 moves upward to act on the corresponding dust collection box 60. Figure 14 and 15 shown.

[0079] In this embodiment, a plurality of dust collecting square tubes 72 are connected by a transverse tube frame 73. Vertical plates 74 are symmetrically provided on both sides of the transverse tube frame 73. The lower ends of the vertical plates 74 are riveted to the dust collecting box 63. A track groove 75 is vertically opened on the inner side surface of each set of vertical plates 74. Both ends of the transverse tube frame 73 are located in the track groove 75 and move up and down along the track groove 75. Figure 14 and 15 shown.

[0080] In this embodiment, the middle portion of the cross pipe frame 73 extends outwardly and is connected to a support base 76. A cylinder 77 is installed on the upper end surface of the dust box 63 and is located on one side of the multi-tube joint 70. A cylinder rod 78 is provided inside the cylinder 77 so as to move upward. The upper end of the cylinder rod 78 is welded to the lower end surface of the support base 76. Figure 14 and 15 shown.

[0081] Furthermore, when the tooling frame 3 moves along with the chain plate to the left end portion of the chain plate conveyor 2 (the stage when the tooling frame 3 starts to move in a downward circular motion), the dust collecting box 60 faces downward and docks with the dust collecting square pipe 72 .

[0082] Furthermore, a filter cloth blower may be installed on the outside of the receiving chute 80 to assist in discharging dust from the dust collecting box 60 .

[0083] When the dust collecting box 60 is in the state of being sucked up, the dust collecting box 60 of this embodiment is in the state of being sucked up, and the dust collecting box 60 of this embodiment is in the state of being sucked up.
