Description

Technical Field

[0001] The 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. An inductor has a certain inductance and only hinders the change of current. If there is no current flowing through the inductor, it will try to hinder the current from flowing through it when the circuit is connected. If there is current flowing 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, so a laser paint stripping machine is used.

[0003] There are many technical defects in the use of existing inductor laser paint stripping machines. First, the inductors are loaded by manual picking or mechanical grabbing, which is time-consuming and labor-intensive and inefficient. When the inductors are grabbed mechanically, they are easy to fall off due to their small size and smooth surface. Second, during the process of unloading the inductors from the vibration plate and transporting them with the belt conveyor, the inductors are easily squeezed and rubbed against each other or contaminated by workshop dust, which causes static electricity on their surface. 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 absorb it in time with a vacuum cleaner. However, 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 for new energy batteries. Summary of the invention

Then the push frame 21 moves linearly to the right in the linear groove, driving the push rod 22 to return, and completing the loading of a group of inductor workpieces 10.

[0056] 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 rotation of the rotating seat 35, 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 by the rotating rod 43. The long tooth portion 52 and the No. 1 gear 45 mesh, so that the long tooth portion 52 moves 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, resulting in the second set of unloading channels 54 in the loading chamber 53 facing the pushing port 14, and then repeating the above operation to complete the loading of the second set of inductive workpieces 10 by using the pushing rod 22, and the cycle is repeated until all the unloading plates 93 in the loading chamber 53 have inductive workpieces 10 placed on them.

[0057] 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 air toward 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 groove, so that several groups of unloading plates 93 immediately evacuate the position of the unloading channel 54, 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, and several groups of inductor workpieces 10 respectively enter the positioning groove 4 to complete precise unloading.

[0058] Then, the tooling frame 3 carrying the inductive workpiece 10 moves straight to the left along with 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 performs 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 of the cracks is immediately blown away with an air pipe, leaving the copper wire part to facilitate the 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. Embodiment 2

[0059] Based on the first embodiment, the powder blown away by the air blowing pipe will form dust in the workshop. The existing measure is to absorb it through a vacuum cleaner. 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 collecting box 60 on the side of each group of positioning grooves 4 away from the air blowing pipe, such as Figure 12-15 shown.

[0060] Specifically, the opening of the dust box 60 and the side of the tooling frame 3 are riveted to play a connecting and fixing role. The dust box 60 is provided with a collection chamber 61 inside, and a layer of filter cloth 62 is laid around the collection chamber 61. The inner wall of the collection chamber 61 is provided with ventilation holes to assist the filtering of the filter cloth 62. Fig.12 and 13 shown.

[0061] Furthermore, a dust collecting box 63 is fixedly arranged inside the machine 1, and the dust collecting box 63 includes a dust collecting motor 64 and a dust collecting bag structure, such as Fig.14 and 15 shown.

[0062] Among them, the upper end surface of the dust box 63 is provided with a multi-tube joint 70, and a plurality of groups of bellows telescopic tubes 71 are connected to the multi-tube joint 70. The bellows telescopic tubes 71 can be extended and retracted with the movement of the dust collecting square tube 72. The upper end of each group of bellows telescopic tubes 71 is sealed and connected to the dust collecting square tube 72. A guide tube groove for extending a plurality of groups of dust collecting square tubes 72 is provided at the right side of the receiving trough 80. The dust collecting square tube 72 moves upward to act on the corresponding dust collecting box 60, such as Fig.14 and 15 shown.

[0063] In this embodiment, a plurality of groups of dust collecting square tubes 72 are connected by a transverse tube frame 73. Vertical plates 74 are symmetrically arranged 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 group 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. Fig.14 and 15 shown.

[0064] In this embodiment, the middle part of the cross pipe frame 73 extends outwardly and is connected to a support seat 76. The upper end surface of the dust box 63 is located on one side of the multi-tube joint 70 and is installed with a cylinder 77. The cylinder 77 is provided with a cylinder rod 78 that moves upward. The upper end of the cylinder rod 78 is welded to the lower end surface of the support seat 76. Fig.14 and 15 shown.

[0065] Furthermore, when the tooling frame 3 moves to the left end of the chain-type conveyor 2 along with the chain plate (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 .

[0066] Furthermore, a filter cloth blower may be installed on the outside of the material receiving trough 80 to assist in discharging dust from the dust collecting box 60 .

[0067] When the present embodiment is in use, the powder blown away by the air blowing pipe will directly enter the collecting chamber 61 on one side of the positioning groove 4 (blowing directly by the air blowing pipe), be intercepted by the filter cloth 62 in the collecting chamber 61, and the powder is adsorbed on the filter cloth 62. When the amount of powder in the dust collecting box 60 reaches the adsorption upper limit of the filter cloth 62, the tooling frame 3 moves to the left end portion of the chain plate conveyor 2 with the chain plate, so that the box opening direction of each group of dust collecting boxes 60 is downward. At this time, the cylinder 77 is started, and the cylinder rod 78 extends upward, driving the support seat 76 to move upward (the cross tube frame 73 moves upward along the track groove 75), so that the guide tube grooves extending from the several groups of dust collecting square tubes 72 on the cross tube frame 73 are respectively connected with the box opening of the dust collecting box 60. At this time, the dust suction motor 64 on the dust collecting box 63 is started, generating a strong suction force to act on the filter cloth 62 of the dust collecting box 60, so that the dust on the filter cloth 62 enters the dust collecting box 63 along the dust suction square tube 72 and the corrugated telescopic tube 71, and is collected centrally.
