Description

Technical Field

[0001] The invention relates to the technical field of fuse assembly, in particular to an automatic assembly machine for plug-in fuses. Background Art

[0002] Fuses are also called current fuses. They are mainly used for overload protection. Fuses are made of lead-antimony alloy with relatively high resistivity and low melting point. When a circuit fails or is abnormal, the current continues to increase. The increased current may damage some important or valuable components in the circuit, or burn the circuit or even cause a fire. During the processing, the fuse is assembled by inserting the fuse pin into the fuse head, and the equipment that completes this assembly step is called a fuse automatic assembly machine.

[0003] Most of the existing automatic fuse assembly machines directly insert the fuse pins into the fuse head to achieve assembly during operation. However, when the fuse pins are inserted, some of the pins will be bent due to truncation, which makes it inconvenient for the automatic assembly machine to align the pins with the mounting holes on the fuse head, thereby facilitating the installation of the equipment.

[0016] Compared with the prior art, the automatic assembly machine for plug-in fuses described in the present invention has a traction structure, which straightens the pins by traction, making it easier for the device to align the pins with the installation part on the fuse head, thereby facilitating precise installation. The device can compensate for the traction structure to avoid one side moving too fast during migration, resulting in an unsatisfactory stretching effect. The device has a kneading structure, which can perform secondary processing on the pins after traction to make the pins straighter. The device has a shielding structure to prevent the pins from coming out from the sides during kneading, affecting the kneading effect.

[0017] Compared with the prior art, the beneficial effects of the present invention include:

[0018] 1. The present invention can make the two racks move synchronously to both ends through the rotation of the first gear, thereby driving the clamping assembly to move, so that the clamping assembly pulls and straightens the fuse pins, so that the cut fuse pins can form a straight shape, which is convenient for the device to align the fuse pins with the mounting holes on the fuse head for installation, thereby increasing the accuracy of equipment installation.

[0019] 2. The present invention uses an external air pipe to evacuate air from the inside of the sleeve, thereby moving the lower connecting plate downward and clamping the fuse pin with the upper clamp block and the lower clamp block. When one of the clamping components moves to the edge of the fuse pin, the L plate loses its shielding and the elasticity of the sixth spring pulls the L plate downward, thereby inserting the inclined surface plug block into the inclined surface slot block and pushing the blocking plate backward, thereby causing the blocking plate to lose its shielding of the lower connecting plate, so that the traction rod can continue to pull the lower connecting plate downward, thereby increasing the clamping force between the upper clamp block and the lower clamp block. In this way, when the remaining at both ends of the fuse pin are inconsistent, the clamping force of the end that moves too fast can be increased, thereby enabling the traction and stretching component to continue to work, thereby preventing one of the clamping components from moving too fast and disengaging from the fuse pin, resulting in the traction and stretching component failing to complete the stretching of the fuse pin, thereby affecting the stretching effect of the equipment.

[0020] 3. After the fuse pin is pulled, the present invention rubs the fuse pin back and forth through the relative movement between the rubbing plate and the base until the fuse pin is completely straight, so as to avoid the situation that the fuse pin is still slightly bent due to the influence of its own stress after pulling, thereby affecting the accuracy of equipment installation.

[0021] 4. The push plate of the present invention forms an elastic structure between the first guide rod and the first spring and the edge guard, and the elastic structure can make the push plate and the kneading plate close together, thereby preventing the fuse pin from coming out from the side of the kneading plate and losing the kneading effect.

[0032] The specific operation is as follows: through the rotation of the first gear 702, the two racks 703 can be moved to both ends synchronously, thereby driving the clamping assembly 9 to move, so that the clamping assembly 9 pulls and straightens the fuse pin 12, so that the cut-off fuse pin 12 can form a straight shape, which is convenient for the device to align the fuse pin 12 with the mounting hole on the fuse head 203 for installation, thereby increasing the accuracy of the equipment installation.

[0033] like Figure 1 , Figure 2 and Figures 6 to 8 As shown, a fixing component 2 is installed on the left side of the interior of the shell 1, and a lifting component 3 is installed on the right side of the interior of the shell 1, a pushing component 4 is installed on the right side of the lifting component 3, and a kneading component 5 is installed on the upper end of the lifting component 3, the lower end of the traction and stretching component 7 is connected to the clamping component 9, and the upper middle part of the traction and stretching component 7 is connected to the power component 10, the rear end of the clamping component 9 is connected to the boosting component 11, and a fuse pin 12 is arranged on the inner side of the clamping component 9.

[0034] like Figure 1 As shown, the fixing assembly 2 includes a first electric slide rail 201, a fixing frame 202, a fuse head 203, a pressing plate 204 and a first cylinder 205, and the fixing frame 202 is installed on the upper end of the first electric slide rail 201, the fuse head 203 is installed inside the fixing frame 202, and the upper end of the fuse head 203 is provided with a pressing plate 204, and the upper end of the pressing plate 204 is connected to the first cylinder 205;

[0035] The first cylinder 205 drives the pressing plate 204 to move and fix the fuse head 203 , and the first electric slide rail 201 moves the fuse head 203 forward and backward.

[0036] like Figure 2 and Figure 3 As shown, the lifting assembly 3 includes a base 301, a side guard 302, a first spring 303, a push plate 304 and a first guide rod 305, and the side guard 302 is installed around the upper end of the base 301, the rear end of the side guard 302 is connected to the first spring 303, and the rear end of the first spring 303 is connected to the push plate 304, and the left and right sides of the push plate 304 are connected to the first guide rod 305;

[0037] The push plate 304 forms an elastic structure with the edge guard 302 through the first guide rod 305 and the first spring 303. The elastic structure can make the push plate 304 and the rubbing plate 505 close together, thereby preventing the fuse pin 12 from coming out from the side of the rubbing plate 505 and losing the rubbing effect.

[0038] like Figure 2As shown, the push assembly 4 includes a guide tube 401, a push rod 402, a second cylinder 403 and a mounting frame 404, and the push rod 402 is arranged inside the guide tube 401, the right side of the push rod 402 is connected to the second cylinder 403, and the outside of the second cylinder 403 is connected to the mounting frame 404;

[0039] The second air cylinder 403 is opened to push the push rod 402, so that the push rod 402 enters the guide tube 401, and the fuse pin 12 is pushed out and inserted into the fuse head 203 to complete the assembly.

[0040] like Figure 2 As shown, the kneading assembly 5 includes a second electric slide rail 501, a bracket 502, a second guide rod 503, a second spring 504 and a kneading plate 505, and the upper end of the second electric slide rail 501 is connected to the bracket 502, the middle part of the bracket 502 is penetrated by the second guide rod 503, and the second spring 504 is arranged outside the second guide rod 503, and the lower end of the second spring 504 is connected to the kneading plate 505;

[0041] After the fuse pin 12 is pulled, the fuse pin 12 will be rubbed back and forth through the relative movement between the rubbing plate 505 and the base 301 until the fuse pin 12 is completely straightened, so as to avoid the fuse pin 12 being slightly bent due to its own stress after pulling, thereby affecting the accuracy of equipment installation.

[0042] like Figure 6 As shown, the clamping assembly 9 includes an upper clamping block 901, a connecting plate 902, a fifth spring 903, a third guide rod 904, a lower connecting plate 905, a traction rod 906, a piston 907, a sleeve 908 and a lower clamping block 909, and the upper clamping block 901 is connected to the rear of the connecting plate 902, the lower end of the connecting plate 902 is connected to the fifth spring 903, and the front and rear sides of the connecting plate 902 are penetrated by the third guide rod 904, the lower end of the third guide rod 904 is connected to the lower connecting plate 905, and the lower end of the lower connecting plate 905 is connected to the traction rod 906, the lower end of the traction rod 906 is connected to the piston 907, and the outside of the piston 907 is connected to the sleeve 908, and the front end of the sleeve 908 is connected to the lower clamping block 909;

[0043] The air inside the sleeve 908 is extracted through an external air pressure device, so that the piston 907 moves downward, and the traction rod 906 pulls the lower connecting plate 905, so that the lower clamping block 909 rises and cooperates with the upper clamping block 901 to clamp the fuse pin 12. The lower connecting plate 905 relies on the elastic structure formed by the fifth spring 903 and the third guide rod 904 and the connecting plate 902 to apply a continuous traction force to the lower clamping block 909, so that the lower clamping block 909 and the upper clamping block 901 remain in a clamped state.

[0044] like Figure 7As shown, the power assembly 10 includes a motor 1001 , a second gear 1002 and a third gear 1003 , and the rotating end of the motor 1001 is connected to the second gear 1002 , and the left side of the second gear 1002 is connected to the third gear 1003 .

[0045] like Figure 8 As shown, the boost assembly 11 includes an L plate 1101, a sixth spring 1102, a fourth guide rod 1103, a lower insert rod 1104, an inclined plane insert block 1105, an inclined plane slot block 1106, a blocking plate 1107 and a guide rail 1108, and the lower end of the L plate 1101 is connected to the sixth spring 1102, the fourth guide rod 1103 is arranged inside the sixth spring 1102, the rear end of the L plate 1101 is connected to the lower insert rod 1104, the lower end of the lower insert rod 1104 is connected to the inclined plane insert block 1105, the outer side of the inclined plane insert block 1105 is connected to the inclined plane slot block 1106, the front end of the inclined plane slot block 1106 is connected to the blocking plate 1107, and the lower end of the blocking plate 1107 is connected to the guide rail 1108;

[0046] The sleeve 908 is evacuated through an external air pipe, so that the lower connecting plate 905 moves downward, and the upper clamping block 901 and the lower clamping block 909 clamp the fuse pin 12. When one of the clamping components 9 moves to the edge of the fuse pin 12, the L plate 1101 loses its shielding, and the elasticity of the sixth spring 1102 pulls the L plate 1101 downward, so that the inclined surface plug block 1105 is inserted into the inclined surface slot block 1106, and the blocking plate 1107 is pushed backward, so that the blocking plate 1107 loses its shielding against the lower connecting plate 905. 05 is blocked, so that the traction rod 906 can continue to pull the lower connecting plate 905 downward, so that the clamping force between the upper clamp block 901 and the lower clamp block 909 becomes larger. In this way, when the remaining at both ends of the fuse pin 12 are inconsistent, the clamping force of the end that moves too fast can be increased, so that the traction and stretching assembly 7 can continue to work, avoiding one of the clamping assemblies 9 moving too fast and separating from the fuse pin 12, resulting in the traction and stretching assembly 7 The stretching of the fuse pin 12 is not completed, affecting the stretching effect of the equipment.

[0047] Working principle: first, place the fuse pin 12 on the lower clamp block 909, and then use an external air pressure device to extract air from the sleeve 908, so that the piston 907 moves downward, and the traction rod 906 pulls the lower connecting plate 905, so that the lower clamp block 909 rises and cooperates with the upper clamp block 901 to clamp the fuse pin 12 until the lower connecting plate 905 contacts the blocking plate 1107 and is blocked, and then turn on the motor 1001, and drive the first gear 702 rotatably connected to the support frame 701 to rotate through the transmission between the second gear 1002 and the third gear 1003, and the two racks 703 are moved to both sides through the meshing between the first gear 702 and the rack 703, thereby driving the two clamping components through the moving plate 706. 9 respectively move to both sides, pull the fuse pin 12, so that the fuse pin 12 is tightened and straightened. When one of the upper clamping blocks 901 moves to the end of the fuse pin 12, the fuse pin 12 no longer blocks the L plate 1101. At this time, the elastic structure formed between the L plate 1101 and the upper clamping block 901 through the sixth spring 1102 and the fourth guide rod 1103 can make the L plate 1101 move downward, so that the lower plug rod 1104 drives the inclined surface plug block 1105 to move downward, and the inclined surface of the inclined surface plug block 1105 cooperates with the inclined surface of the inclined surface slot block 1106. During the descending process of the inclined surface plug block 1105, the inclined surface slot block 1106 moves backward, so that the blocking plate 1107 slides backward on the guide rail 1108. , so that the blocking plate 1107 loses its shielding of the lower connecting plate 905. At this time, the traction rod 906 will continue to move downward under the influence of the internal air pressure of the sleeve 908, thereby continuing to pull the fifth spring 903, increasing the clamping force between the upper clamp block 901 and the lower clamp block 909, thereby increasing the friction between the upper clamp block 901 and the lower clamp block 909 and the fuse pin 12, so that the friction force of the clamping assembly 9 close to the end of the fuse pin 12 is greater than the clamping assembly 9 at the other end, so that the clamping assembly 9 at the other end can be moved until the two clamping assemblies 9 are at the end of the fuse pin 12, thus completing the traction of the fuse pin 12, and the position of the movable plate 706 is detected by the infrared distance sensor 8. To determine whether the traction is completed, because when the traction is completed, the two clamping components 9 will move to the specified position. When the infrared distance sensor 8 detects that the clamping component 9 has reached the specified position, the air pipe connected to the lower end of the sleeve 908 loses its suction function, so that the air can be replenished inside the sleeve 908. The gravity of the lower clamping block 909 will separate the lower clamping block 909 and the upper clamping block 901, releasing the clamping. At the same time, the fuse pin 12 moves downward with the lower clamping block 909. At this time, the movable plate 706 can pull the clamping component 9 through the elastic structure formed by the fourth spring 705 and the support guide rod 707 and the lower rod 704, so that the two clamping components 9 are close to reset. At the same time, the blocking plate 1107 will also be reset under the influence of the magnetic force at the end of the guide rail 1108.Magnets are installed on the end of the guide rail 1108 and the blocking plate 1107. At the same time, the third cylinder 6 will also drive the traction and stretching component 7 to descend, so that the clamping component 9 drives the fuse pin 12 to approach the end of the rubbing plate 505. The extension and retraction of the third cylinder 6, the resetting of the clamping component 9 and the resetting of the blocking plate 1107 are all performed synchronously. When the clamping component 9 moves to the rubbing plate 505, the clamping component 9 is also reset. At this time, the fuse pin 12 will be unevenly stressed due to the resetting of the clamping component 9, so that the fuse pin 12 will fall between the rubbing plate 505 and the push plate 304. The reason for the fuse pin 12 to fall is not only the uneven force on both sides when approaching, but also the impact force generated when the two clamping components 9 are close to each other, which will cause the fuse pin 12 to vibrate and fall. When the fuse pin 12 falls to the rubbing plate 505, the second electric slide rail 501 is opened to drive the bracket 502 to move, so that the rubbing plate 505 moves forward and backward. When the rubbing plate 505 moves backward, the push plate 304 pushes the fuse pin 12 by relying on the elastic structure formed by the first spring 303 and the first guide rod 305 and the edge guard 302, so that the fuse pin 12 rolls to the base 301. The rubbing plate 505 is on the groove, and then when the rubbing plate 505 moves forward, the rubbing plate 505 will move above the fuse pin 12 due to the influence of the groove on the base 301 on the fuse pin 12. Here, the rubbing plate 505 forms an elastic structure with the second spring 504 and the second guide rod 503 and the bracket 502, so that the rubbing plate 505 can be raised and lowered when encountering resistance, so the rubbing plate 505 can move above the fuse pin 12, and then the second electric slide rail 501 will continue to drive the rubbing plate 505 to rub the fuse pin 12 continuously until the fuse pin 12 falls straight. The second cylinder 403 is then turned on to push the push rod 402, so that the push rod 402 enters the guide tube 401, and the fuse pin 12 is pushed out and inserted into the fuse head 203 to complete the assembly. When the fuse pin 12 is straightened, the fuse head 203 is placed on the fixing frame 202, and then the first cylinder 205 drives the pressing plate 204 to move and fix the fuse head 203, and the first electric slide rail 201 moves the fuse head 203 back and forth until the installation hole of the fuse head 203 is aligned with the largest groove on the base 301.
