Description

Technical Field

[0001] The invention relates to the technical field of capacitor production and processing, and in particular to a tipping detection component for a capacitor assembling machine. Background Art

[0002] During the operation of the capacitor assembly machine, the capacitor is transported through the conveying channel and transferred to the processing station by the clamp. In this process, it often happens that the capacitor falls over during the transportation in the conveying channel. If the staff cannot find it in time, the clamp will not be able to clamp the capacitor at a suitable angle. When the clamp places the offset capacitor on the processing station, the offset placement of the capacitor will directly lead to the scrapping of the product.

[0024] The first L-shaped clamp arm 14 and the first clamp arm 15 are respectively connected to a side surface of the mounting seat 16 through the second positioning pin 36, and a first return spring 17 is connected between the first L-shaped clamp arm 14 and the first clamp arm 15; the first push-pull drive motor 28 is fixedly installed on the machine platform of the capacitor assembly machine, and the power output end of the first push-pull drive motor 28 is hinged to one end of the first pressure rod 27, and the first pressure rod 27 is rotatably connected to one side of the second push-pull drive motor 25 through the rotating shaft 43 on the side close to the first push-pull drive motor 28, and the free end of the first L-shaped clamp arm 14 is extended to the side below the first pressure rod 27 and forms a vertical relationship with the first pressure rod 27, and the second bearing sleeve 21 is installed at the position corresponding to the first L-shaped clamp arm 14 and the first pressure rod 27; the fourth bearing sleeve 46 is installed at the position corresponding to the first L-shaped clamp arm 14 and the second pressure rod 19;

By setting the third reset spring 30, the L-shaped push rod 29 can be automatically reset.

[0026] Preferably, the outer side surface of the first positioning pin 35 is sleeved with a first bearing sleeve 32. By providing the first bearing sleeve 32, the lever 33 can be in contact with the first bearing sleeve 32 to form a rotational pushing state, thereby reducing the friction with the first positioning pin 35, which can reduce the friction on the one hand and improve the smoothness of the displacement of the L-shaped push rod 29 on the upper surface of the first guide block 31 on the other hand.

[0027] Preferably, an L-shaped mounting plate 41 is installed on the outer side of the second push-pull drive motor 25, the power output end of the second push-pull drive motor 25 passes through the L-shaped mounting plate 41 and extends outside the L-shaped mounting plate 41, and the rotating shaft 43 is fixedly mounted on the outer side of the L-shaped mounting plate 41.

[0028] Preferably, the second push-pull drive motor 25 is fixedly connected to the second guide blocks 26 on both sides thereof, and the second pressure rod 19 is fixedly connected to the second guide rods 22 on both sides thereof located at the push-pull rod 24; the two second guide blocks 26 are both provided with guide holes for receiving the second guide rods 22. By providing the matching structure of the second guide blocks 26 and the second guide rods 22, the stability of the second pressure rod 19 during the up-and-down displacement is ensured, and shaking during the up-and-down displacement is prevented.

[0029] Preferably, the two second guide rods 22 are located between the second pressure rod 19 and the upper surface of the second guide block 26 and are sleeved with a buffer spring 23 to improve the resetting flexibility of the second pressure rod 19 after the downward pressing action.

[0030] Preferably, a connecting arm 44 is connected to the lower part of one side of the L-shaped mounting plate 41 by a bolt 45, and a photoelectric sensor 12 is installed at the free end of the connecting arm 44. With such a structural setting, the height of the photoelectric sensor 12 can be adjusted at any time by loosening the bolt 45, which is easy and quick to operate.

[0031] The operating principle of this embodiment is: the pushing structure is used to drive the first clamping structure 40 and the second clamping structure 39 to move back and forth between the capacitor assembly machine conveyor belt 10 and the capacitor assembly machine processing station, and the photoelectric sensor 12 is used to sense the top of the capacitor 11. If it can be sensed, it is judged to be normal, and if it cannot be sensed, it is judged to be abnormal; the first clamping structure 40 is used to transfer the capacitor 11 on the capacitor assembly machine conveyor belt 10 to the temporary material collection station between the capacitor assembly machine processing station and the capacitor assembly machine conveyor belt 10, and the second clamping structure 39 is used to transfer the capacitor of the temporary material collection station to the capacitor assembly machine processing station. In actual operation, the first clamping structure 40 and the second clamping structure 39 act synchronously; the specific steps are as follows:

[0032] 1. The capacitor 11 is transported through the capacitor assembly machine conveyor belt 10;

[0033] 2. The capacitor 11 moves to the position corresponding to the photoelectric sensor 12. If the photoelectric sensor 12 can sense the capacitor 11 normally, the control system determines that it is normal. The second push-pull drive motor 25 drives the second pressure rod 19 to move downward through the push-pull rod 24. The second pressure rod 19 simultaneously presses down the third bearing sleeve 42 and the fourth bearing sleeve 46, thereby respectively causing the second L-shaped clamp arm 37 and the first L-shaped clamp arm 14 to be in an open state. The second push-pull drive motor 25 drives the second pressure rod 19 to move upward through the push-pull rod 24. The second clamping structure 39 and the first clamping structure 40 respectively realize the clamping action of the capacitor under the reset force of the reset spring; subsequently, the first rotary drive motor 34 outputs power, and drives the first bearing sleeve 32 through the lever 33 to drive the L-shaped push rod 29, the second clamping structure 39, the first clamping structure 40 ... A clamping structure 40 moves toward the capacitor assembly machining station, and the capacitor of the first clamping structure 40 is placed on the temporary material picking station. The second clamping structure 39 moves the capacitor originally located at the temporary material picking station to the capacitor assembly machining station. Subsequently, the second push-pull drive motor 25 drives the second pressure rod 19 to move downward again through the push-pull rod 24. The second pressure rod 19 simultaneously presses down the third bearing sleeve 42 and the fourth bearing sleeve 46, thereby respectively causing the second L-shaped clamp arm 37 and the first L-shaped clamp arm 14 to be in an open state, thereby placing the capacitor in a corresponding position. The first rotary drive motor 34 stops power output, and the L-shaped push rod 29 drives the second clamping structure 39 and the first clamping structure 40 to reset to the starting position under the reset force of the third reset spring 30, so as to prepare for the next clamping action;

[0034] 3. Then the capacitor 11 is basically moved to the position corresponding to the photoelectric sensor 12. If the photoelectric sensor 12 fails to sense the capacitor 11 normally, the control system will determine it as abnormal, and the photoelectric sensor 12 will feed back the signal to the control system. The control system will control the first push-pull drive motor 28 to operate, and the first push-pull drive motor 28 outputs power to drive the first pressure rod 27 to press down the second bearing sleeve 21 with the rotating shaft 43 as the support point, thereby prompting the first clamping structure 40 to remain in an open state, that is, the clamping action of the first clamping structure 40 is blocked in time, and the machine is temporarily shut down. Under the reminder of the control system, the staff has sufficient time to deal with the abnormal capacitance in time. After the abnormal capacitance is corrected, the machine is started again and the material taking action in step 2 is repeated.

[0035] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
