[0018] S3, check for broken tool. At this time, the tool head is located on the inner wall of the circular sleeve in the detection device. When the drilling tool head is not broken, the tool head touches the rubber pad and presses the push-button switch to turn on the indicator light. When the drilling tool head is broken, it will not touch the rubber pad, and the indicator light will not light up, so you can know in time whether the tool head is broken.

[0019] S4, Replace the drill bit. After detecting a broken drill bit, the automatic detection and adjustment device is activated and automatically moves and resets, allowing the drill bit to be removed and replaced.

[0020] (III) Beneficial Effects

[0021] The broken tool detection device for smart home circuit board processing equipment provided by this invention has the following beneficial effects:

[0022] 1. The broken tool detection device of this smart home circuit board processing equipment, after the circular sleeve is positioned, activates the electric telescopic rod to pull the arc-shaped groove plate and L-shaped plate downwards simultaneously. At this time, the sleeve rod is pressed and slides downwards in the spiral groove through the mounting shaft. As it continues to move downwards until the circular sleeve is no longer fitted onto the outer wall of the drilling head, the mounting shaft is squeezed by the spiral groove, causing the sleeve rod to deflect. This causes the L-shaped plate to rotate around the fulcrum of the sleeve rod, so that one end of the L-shaped plate slides in the arc-shaped groove through the movable shaft. This deflects the entire L-shaped plate to the lower part away from the drilling mechanism, which is beneficial for the drilling mechanism to perform drilling processing on the circuit board. After the drilling mechanism finishes its work and rises, the electric telescopic rod is activated to push the arc-shaped groove plate and L-shaped plate upwards. The mounting shaft on the outer wall of the sleeve will be deflected to the upper part of the worktable by the extrusion of the spiral groove. After the deflection is completed, the L-shaped plate and the circular sleeve will continue to rise to the outer wall of the drilling head. If the drilling head is not broken, it will contact the rubber pad and press the push-button switch to turn on the indicator light, thus reminding the operator that no tool breakage has occurred. If no tool breakage has occurred, the drilling head will not contact the rubber pad and the indicator light will not light up. If the drilling head is broken, it needs to be replaced. Its continuous structure can automatically move to the lower part of the tool head to detect tool breakage. When not in use, the detection mechanism can be reset and will not block the tool head from working, saving the trouble of repeatedly moving the detection mechanism for detection. It can also be seen intuitively whether a tool breakage has occurred, improving the convenience of detection.

[0023] 2. The broken tool detection device of this smart home circuit board processing equipment first adjusts the position of the circular sleeve according to the position of the drilling head before testing. Holding the second end face toothed disc, pull it away from the drilling head, causing the spring telescopic rod to stretch so that the second end face toothed disc is not engaged with the first end face toothed disc. Then, manually rotate the spiral groove column so that the groove on its outer wall squeezes the sliding shaft, causing the square frame to slide on the upper part of the L-shaped plate. This allows adjustment of the lateral movement of the mounting frame and the circular sleeve. Furthermore, when the second end face toothed disc is pulled outwards, it simultaneously drives the lower L-shaped plate... The triangular plate moves closer to the outer wall of the T-shaped plate, squeezing the T-shaped plate away from the L-shaped plate and stretching the limiting telescopic rod. When the T-shaped plate is squeezed and moved, it will pull the upper sliding column downwards in sync, pulling the long rack away from engaging with the limiting teeth. It will also simultaneously drive the limiting spring on the outer wall of the sliding column to be stretched. At this time, the circular sleeve can be slid longitudinally in the mounting frame with the sliding block, so that the horizontal and vertical distances of the circular sleeve can be adjusted at the same time. It can be flexibly applied to the position of the drilling head when drilling in different positions, and the operation is convenient and the detection mechanism can be quickly adjusted for displacement and positioning.

[0024] 3. The broken tool detection device of this smart home circuit board processing equipment only requires loosening the second end face toothed disc. At this time, the spring telescopic rod will reset and re-engage with the first end face toothed disc, so that the spiral groove column will not rotate. When the second end face toothed disc is pulled and reset, it will no longer pull the L-shaped triangular plate, thus avoiding contact with the T-shaped plate. At this time, the limit spring resets and pulls the sliding column and the T-shaped plate to move upward and reset. This causes the sliding column to push the long toothed rack upward and re-engage with the limit tooth at the bottom of the circular sleeve, thus limiting and fixing the circular sleeve. This effectively prevents the phenomenon of movement caused by subsequent contact and ensures the accuracy of the detection after positioning.

[0025] 4. The broken tool detection device of this smart home circuit board processing equipment: When the drilling mechanism drills a circuit board placed on the worktable downwards, the drill bit will squeeze the rubber plate as it passes through the circuit board and continues to descend. The rubber plate will compress the spring telescopic rod as it descends. At this time, the long shaft at the rear of the rubber plate will be squeezed by the inclined groove and move closer to the outer wall of the drilling mechanism. This causes the long shaft to drive the pressing plate to slide in the groove at the rear of the rubber plate. This will cause the pressing plate to press the switch button to close the descent of the drilling mechanism. This can effectively prevent the drill bit from breaking when it continues to descend and touches the hard table surface, thus reducing the probability of wear on the drill bit.

[0026] 5. The broken tool detection device of this smart home circuit board processing equipment, when the electric telescopic rod moves up and down, its outer wall will pull the threaded sleeve up and down through the support rod, causing the threads on the inner wall of the threaded sleeve to squeeze the threaded rod and drive the rectangular frame to deflect synchronously. When the rectangular frame deflects, it will move the moving shaft to slide on its inner wall, thereby pulling the cleaning rod to slide longitudinally on the upper part of the rubber plate. This can push out the debris left by drilling on the upper part of the rubber plate, avoiding the subsequent drilling head from continuously touching the debris downwards, which would not effectively resist the downward movement of the rubber plate and prevent the drilling mechanism from being unable to close in time. It can also keep the upper part of the rubber plate clean and prevent the debris from piling up and affecting subsequent drilling. Attached Figure Description

[0054] Example 5

[0055] Please see Figure 12 Regarding the aforementioned broken tool detection device for smart home circuit board processing equipment, a method for detecting broken tools in smart home circuit board processing equipment is now proposed, comprising the following steps:

[0056] S1, Position the drilling head 4. First, adjust the detection device according to the position of the drilling cutter so that the detection head of the automatic detection adjustment mechanism 5 is in the same position as the drilling head 4.

[0057] S2, Automatic moving detection: During circuit board processing, the drilling mechanism 3 is started first to drill holes in the circuit board. After drilling is completed, the automatic detection and adjustment mechanism 5 is started and moves to the lower part of the drilling head 4 to be detected.

[0058] S3, detect if the tool is broken. At this time, the tool head is located on the inner wall of the circular sleeve 514 in the detection device. When the drilling tool head 4 is not broken, the tool head touches the rubber pad 518 and presses the push-button switch 516 to turn on the indicator light 515. When the drilling tool head 4 is broken, it will not touch the rubber pad 518, and the indicator light 515 will not light up, so it can be known in time whether the tool head is broken.

[0059] S4, Replace the cutting head. After detecting a broken cutting head, the automatic detection and adjustment device 5 is activated and automatically moves and resets, allowing the drilling cutting head 4 to be removed and replaced.

[0060] Working principle: First, before testing, adjust the position of the circular sleeve 514 according to the position of the drill bit 4. Hold the second end face toothed disc 524 and pull it away from the drill bit 4, which will cause the spring telescopic rod 523 to stretch so that the second end face toothed disc 524 is not engaged with the first end face toothed disc 522. Then, manually rotate the spiral groove column 59 so that the groove on its outer wall squeezes the sliding shaft 510, causing the square frame 511 to slide on the upper part of the L-shaped plate 56. This allows adjustment of the lateral position of the mounting frame 512 and the circular sleeve 514. When the second end face toothed disc 524 is pulled outward, it will simultaneously drive the lower L-shaped triangular plate 528 towards the T-shaped plate 526. The outer wall approaches and squeezes the T-shaped plate 526 away from the L-shaped plate 56 and stretches the limiting telescopic rod 525. When the T-shaped plate 526 is squeezed and moved, it will pull the upper sliding column 520 to move downward in sync, pulling the long rack 519 out of engagement with the limiting tooth 527. It will also simultaneously drive the limiting spring 521 on the outer wall of the sliding column 520 to be stretched. At this time, the circular sleeve 514 can be slid longitudinally in the mounting frame 512 in conjunction with the sliding block 513. Thus, the horizontal and vertical distances of the circular sleeve 514 can be adjusted at the same time. It can be flexibly applied to the position of the drilling head 4 when drilling in different positions. It is also convenient to operate and can quickly adjust the detection mechanism for displacement positioning.

[0061] Furthermore, once the second end face toothed disc 524 is loosened, the spring telescopic rod 523 will reset and re-engage with the first end face toothed disc 522, preventing the spiral groove column 59 from rotating. When the second end face toothed disc 524 is pulled back to reset, it will no longer pull the L-shaped triangular plate 528, thus avoiding contact with the T-shaped plate 526. At this time, the limiting spring 521 resets and pulls the sliding column 520 and the T-shaped plate 526 upward to reset, causing the sliding column 520 to push the long rack 519 upward to re-engage with the limiting tooth 527 at the lower part of the circular sleeve 514. This can limit and fix the circular sleeve 514, effectively preventing movement caused by subsequent contact and ensuring the accuracy of the detection after positioning.

[0062] After the circular sleeve 514 is positioned, the electric telescopic rod 51 is activated to retract, which pulls the arc-shaped groove plate 52 and the L-shaped plate 56 downwards simultaneously. At this time, the sleeve rod 55 is pressed and slides downwards in the spiral groove 57 through the mounting shaft 58. As it continues to move downwards until the circular sleeve 514 is no longer fitted onto the outer wall of the drilling head 4, the mounting shaft 58 is squeezed by the spiral groove 57, causing the sleeve rod 55 to deflect. This causes the L-shaped plate 56 to rotate around the fulcrum of the sleeve rod 55, so that one end of the L-shaped plate 56 slides in the arc-shaped groove plate 52 through the movable shaft 53. This allows the entire L-shaped plate 56 to be deflected to the lower part away from the drilling mechanism 3, which is beneficial for the drilling mechanism 3 to perform drilling operations on the circuit board. After the drilling mechanism 3 finishes its work and rises, the electric telescopic rod 51 is activated to push the arc-shaped groove plate 52 and the L-shaped plate 56 upwards. At this time, the sleeve rod 55... The mounting shaft 58 on the outer wall will be deflected to the upper part of the worktable 2 by the extrusion of the spiral groove 57. After the deflection is completed, the L-shaped plate 56 and the circular sleeve 514 will continue to rise to the outer wall of the drilling head 4. If the drilling head 4 is not broken, it will contact the rubber pad 518 to press the push switch 516 to turn on the indicator light 515, which can remind the operator that no tool breakage has occurred. If no tool breakage has occurred, the drilling head 4 will not contact the rubber pad 518, so the indicator light 515 will not light up. If the drilling head 4 is broken, it needs to be replaced. Its continuous movement can automatically move to the lower part of the tool head to detect tool breakage. When not in use, the detection mechanism can be reset and will not block the tool head from working, saving the trouble of repeatedly moving the detection mechanism for detection. It can also be seen intuitively whether a tool breakage has occurred, improving the convenience of detection.

[0063] When the drilling mechanism 3 drills a hole in the circuit board placed on the worktable 2, the drill bit 4 passes through the circuit board and continues to descend, which will squeeze the rubber plate 62. The rubber plate 62 will compress the spring telescopic rod 61. At this time, the long shaft 63 at the rear of the rubber plate 62 will be squeezed by the inclined groove 612 and move closer to the outer wall of the drilling mechanism 3. This will cause the long shaft 63 to drive the pressing plate 64 to slide in the groove at the rear of the rubber plate 62. This will cause the pressing plate 64 to abut the switch button 65 to stop the drilling mechanism 3 from descending. This can effectively prevent the drill bit 4 from falling and hitting the hard table surface, causing it to break. This can reduce the probability of the drill bit 4 being worn.

[0064] When the electric telescopic rod 51 moves up and down, its outer wall will pull the threaded sleeve 610 up and down through the support rod 611. This causes the threads on the inner wall of the threaded sleeve 610 to squeeze the threaded rod 66, which in turn causes the rectangular frame 67 to deflect synchronously. When the rectangular frame 67 deflects, it will move the moving shaft 68 to slide on its inner wall, thereby pulling the cleaning rod 69 to slide longitudinally on the upper part of the rubber plate 62. This can push out the debris left by drilling on the upper part of the rubber plate 62, preventing the subsequent drilling head 4 from continuously touching the debris downwards. This would prevent the rubber plate 62 from being unable to effectively resist downwards, thus preventing the drilling mechanism 3 from being unable to close in time. It can also keep the upper part of the rubber plate 62 clean, preventing the debris from piling up and affecting subsequent drilling.

[0065] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
