Description

Technical Field

[0001] The invention relates to the technical field of spark plug production equipment, and in particular to a packaging machine for a spark plug sintering furnace. Background Art

[0002] It is known that the spark plug is an important component of the gasoline engine ignition system. It can introduce high voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wire nut, an insulator, a wire screw, a center electrode, a side electrode and a shell, and the side electrode is welded to the shell. The existing spark plug sintering furnace includes a heating sintering furnace and a packaging machine (such as the workstation spark plug sintering furnace produced by Nanjing Huale Spark Plug Intelligent Equipment Center). The packaging machine includes a manipulator and a conveyor belt. The conveyor belt is equipped with a cold air blower. The heated and baked spark plugs are cooled by the cold air blower, and then the material is taken manually. A magnet is arranged on this manipulator, and a downward-pushing iron plate is arranged on the lower surface of the magnet. When the manipulator runs onto the conveyor belt, the iron plate moves downward, pushing the spark plugs attracted on the lower surface onto the conveyor belt. The following defects exist in the existing spark plug production equipment:

[0003] First, in the prior art, when the spark plugs after heating are grabbed onto the conveyor belt by the manipulator, the spark plugs in the manipulator are attracted by the magnet. Sometimes the magnetic force is small, so it is not possible to attract all the baked spark plugs to the manipulator through the magnet at one time. At this time, it is necessary to manually remove the spark plugs that have not been grabbed. This phenomenon of incomplete material removal will inevitably increase the process links and increase labor costs.

[0004] Second, in the prior art, when the spark plug after heating is grabbed onto the conveyor belt by the manipulator, when the manipulator moves above the conveyor belt, the spark plug in the manipulator is attracted by the magnet, and the iron plates on the lower surface of the magnet move towards each other, so that the spark plug falls onto the conveyor belt by gravity. This natural falling mode will damage the spark plug itself, which will inevitably cause the spark plug produced to be substandard and ultimately fail to meet production requirements;

[0005] Third, in the prior art, when the last air cooler is cooling, a special manual position is required to manually load the materials one by one. The production efficiency is not high enough to meet the requirements of current mass production. At the same time, the work intensity and difficulty will increase, which will inevitably increase the work intensity of the workers and make the operation difficult.

[0006] In view of the above defects, it is necessary to provide a packaging machine which is specially capable of automatically taking, cooling and unloading the spark plugs after baking. Summary of the invention

[0007] 1. Technical issues to be resolved

[0008] In view of the defects in the prior art, the present invention provides a packaging machine for a spark plug sintering furnace, which is intended to be a packaging machine that automatically loads, transports, cools and unloads the spark plugs after they are heated and baked.

The first photoelectric switch 21, the anti-demolding device 22 and the feeding mechanism 23 are all connected to a controller. When the first photoelectric switch 21 senses the spark plug, the anti-demolding device 22 will work to press the mounting seat with the spark plug from the outlet of the baking link, and the feeding mechanism 23 will absorb the spark plug and transfer the absorbed spark plug to the cooling device 3 through the feeding mechanism 23.

[0053] like Figure 3 The feeding mechanism 23 comprises a first mounting frame 231, a first horizontal direction moving device 232 is mounted on the first mounting frame 231, a connecting seat 233 is mounted on the first horizontal direction moving device 232, a first vertical direction moving device 234 is mounted on the connecting seat 233, and a material grabbing mechanism 235 is arranged on the first vertical direction moving device 234. The first mounting frame 231 comprises a first side mounting frame 2311 and a second side mounting frame 2312, the first side mounting frame 2311 and the second side mounting frame 2312 are arranged opposite to each other, and the first horizontal direction moving device 232 is arranged between the first side mounting frame 2311 and the second side mounting frame 2312. The first horizontal motion device 232 includes a linear rail 2321 and a slide 2322. A connecting seat 233 that can move back and forth is provided on the linear rail 2321 and the slide 2322. A slider 2323 that matches the linear rail 2321 is provided on the connecting seat 233. A bottom block 2324 that matches the slide 2322 is provided on the connecting seat 233. A lead screw 2325 is provided on the slide 2322. A servo motor 2326 is connected to one end face of the lead screw 2325. The lead screw 2325 is connected to the bottom block 2324 through a nut. The first vertical motion device 234 uses a vertical cylinder. Figure 4As shown, the material grabbing mechanism 235 includes a demoulding cylinder 2351, a strong magnet placing plate 2352 and a material suction plate 2353. The lower end of the first up-down direction moving device 234 is connected to the demoulding cylinder 2351. The lower surface of the demoulding cylinder 2351 is provided with a strong magnet placing plate 2352. The lower surface of the strong magnet placing plate 2352 is provided with a material suction plate 2353. The lower surface of the strong magnet placing plate 2352 is provided with a plurality of grooves 2354. A magnet 2355 is installed in each groove 2354. The material suction plate 2353 is provided with a plurality of tapered holes 2356. The tapered holes 2356 are 60 degrees (which is beneficial to avoid strong The magnet 2355 installed in the strong magnet placement plate 2352 falls off), the tapered hole 2356 corresponds to the magnet 2355 in the groove 2354 one by one, an anti-drop plate 2357 is arranged between the strong magnet placement plate 2352 and the suction plate 2353 to prevent the magnet 2355 from falling off, and the anti-drop plate 2357 is made of a stainless steel plate with a thickness of 1 mm, a pad 2358 is arranged between the demoulding cylinder 2351 and the strong magnet placement plate 2352, and a seat 2359 is arranged on the first up-down direction motion device 234, and a guide column 2350 is arranged between the pad 2358 and the seat 2359. An anti-drop plate 27 is arranged on the lower surface of the strong magnet placement plate 23 to prevent the magnet 26 from falling off. When the demoulding cylinder 2351 is in use, the demoulding cylinder 2351 drives the strong magnet placing plate 2352 to move down along the guide column 2350. At this time, the magnet 2355 is closest to the tapered hole 2356 in the suction plate 2353, so that the spark plug is sucked through the tapered hole 2356 in the suction plate 2353; when the demoulding cylinder 2351 drives the strong magnet placing plate 2352 to move up along the guide column 2350, at this time, the magnet 2355 is farthest from the tapered hole 2356 in the suction plate 2353, so that the magnetism of the spark plug sucked by the magnet 2355 in the strong magnet placing plate 2352 and the tapered hole 2356 in the suction plate 2353 is reduced, so that the sucked spark plug will be placed on the ceramic support 323 of the automatic transport material circulation belt 32 on the corresponding cooling device 3, so that it will be cooled in the next step.

[0054] The tapered hole 2356 is 60 degrees. The spark plug is straightened when sucking material. When the tapered hole 2356 is sucked, there will be no shaking, thereby achieving the goal of sucking the spark plug or falling off the spark plug, which is beneficial to reduce collisions during movement, and is also beneficial to the natural falling method, which is beneficial to reduce damage to the spark plug itself, and the production of spark plugs can better meet the standards.

[0055] like Figure 5As shown, the anti-stripping device 22 includes a base 221, a cylinder 222, a cylinder guide bracket 223 and a fork 224. The base 221 is installed on the outlet of the spark plug sintering furnace 1 at the workstation. The upper surface of the base 221 is provided with a cylinder 222 and a cylinder guide bracket 223. The cylinder 222 is connected with a fork 224, and the cylinder 222 drives the fork 224 to move back and forth along the cylinder guide bracket 223. On the chain plate at the outlet of the spark plug sintering furnace, the spark plugs that have been roasted are placed on the chain plate through the support. When the spark plug runs to the position of the manipulator, the cylinder 222 first drives the fork 224 to move back and forth along the cylinder guide bracket 223, and the spark plug passes through the fork 224, and the fork 224 presses the support, so that the grabbing mechanism 235 on the feeding mechanism 23 grabs the spark plug and transfers it to the ceramic support 323 of the automatic transport material circulation belt 32 in the cooling device 3 for cooling.

[0056] The cooling device 3 is arranged at the next step of the material taking device 2 process, and can automatically cool down the spark plug transmitted by the material taking device 2.

[0057] Among them, Figure 6 As shown, the cooling device 3 includes a base 31, on which an automatic material conveying circulation belt 32 and a sensing device 33 are provided, and at least one detection device 34 is provided on the automatic material conveying circulation belt 32. A cooling fan 35 facing the spark plug cold zone on the automatic material conveying circulation belt 32 is installed above the base 31, and the automatic material conveying circulation belt 32, the sensing device 33 and the cooling fan 35 are all connected to a controller. The operation of the automatic material conveying circulation belt 32 and the cooling fan 35 is controlled by the controller. When the sensing device 33 detects the detection device 34, the sensing device 33 will notify the controller, and the controller will notify the automatic material conveying circulation belt 32 to suspend operation. Figure 7 As shown, the automatic conveying material circulation belt 32 includes chains 321 on both sides and chain plates 322 between the chains 321 on both sides. The chain plates 322 are provided with at least one ceramic holder 323 for vertically placing spark plugs, and a detection device 34 is provided on the chain plates 322. The detection device 34 is a bolt. The induction device 33 is a proximity switch. Ten cooling fans 351 are provided on the cooling fan 35, and each cooling fan 351 is evenly spaced.

[0058] Among them, the two ends of the chain 321 on both sides are provided with a rotating shaft, wherein the quotient obtained by dividing the total length of the chain 321 by the length of a single chain plate 322 is obtained by subtracting the arc length of the semicircular arc of the rotating shaft from the quotient to obtain the number (quantity) of the chain plates 322. For example, the number of chain plates 322 in this embodiment is fifty, which is obtained in this way, so it is also beneficial to cool the temperature of the spark plugs out of the spark plug sintering furnace from 300°C to 40-50°C through the cooling fan 35, which is more conducive to the subsequent processing and production. At least one ceramic holder 323 for loading and vertically placing the spark plug is provided on each chain plate 322. In this embodiment, each chain plate 322 is provided with four rows and five columns, a total of twenty ceramic holders 323, so that twenty spark plugs can be placed at one time, which greatly improves the production efficiency. Ten cooling fans 351 are provided on the cooling fan 35, and each cooling fan 351 is evenly spaced. This is also beneficial for cooling the temperature of the spark plugs emerging from the spark plug sintering furnace from 300° C. to 40 to 50° C. through the cooling fan 35, which is more beneficial for subsequent processing and production.

[0059] The unloading and loading device 4 is arranged at the next step of the cooling device 3 process, and can automatically load the spark plugs after being cooled by the cooling device 3 .

[0061] The loading tray slide device 43 includes a second slide 431 and a second servo motor 432 . The second servo motor 432 is arranged on the end surface of the second slide 431 . The loading tray 48 is installed on the second slide 431 and slides back and forth along the second slide 431 .

[0062] The second horizontal motion device 44 includes a servo motor 3 441 and a slide 3 442. The servo motor 3 441 is arranged on the side end surface of the slide 2 442. The slide 3 442 is provided with a slide seat 45 that slides back and forth along the slide 3 442. The second up-and-down motion device 46 includes an aluminum plate mounting seat 461, a vertical cylinder 462 and a slide rail 463. The slide seat 45 is provided with two slide rails 463. The vertical cylinder 462 is connected to the aluminum plate mounting seat 461 through a movable joint 464. The upper unloading device 47 is installed on the aluminum plate mounting seat 461.

[0063] The upper unloading device 47 includes a fixed plate 471, a spacing cylinder 472, a finger cylinder 473 and a track 474. The fixed plate 471 is fixed on the second up-and-down moving device 46. The spacing cylinder 472 is arranged on one end face of the fixed plate 471. Two tracks 474 are arranged on the other end face of the fixed plate 471. The two tracks 474 are equipped with a material grabbing clamp 475. The material grabbing clamp 475 is equipped with a finger cylinder 473. The finger cylinder 473 is equipped with a chuck 476 for clamping the spark plug. The spacing cylinder 472 adopts an ultra-thin cylinder (ACQ cylinder). A rubber pad is arranged on the inner side of the chuck 476, which is conducive to protecting the clamped spark plug product from damage and is more conducive to clamping the spark plug product.

[0064] Among them, the grabbing clamp 475 includes a fixed hand clamp 4751 and at least one movable hand clamp 4752, the upper end faces and lower end faces of the fixed hand clamp 4751 and the movable hand clamp 4752 are respectively connected together through an upper connecting plate 4753 and a lower connecting plate 4754, the fixed hand clamp 4751 is fixedly connected to the spacing cylinder 472 by bolts, and the spacing cylinder 472 is connected to the movable hand clamp 4752 at the starting end by a pin, and each upper end face and lower end face of the remaining number of movable hand clamps 4752 are provided with an upper limit hole and a lower limit hole, and the upper limit hole and the lower limit hole are installed with corresponding upper limit pins and lower limit pins, and the upper limit pins and the lower limit pins are correspondingly connected to the upper connecting plate 4753 and the lower connecting plate 4754.

[0065] Among them, the fixed hand clamp 4751 and at least one movable hand clamp 4752, specifically, one fixed hand clamp 4751 and four movable hand clamps 4752, and the lower end surfaces of the fixed hand clamp 4751 and the four movable hand clamps 4752 are all provided with finger cylinders 473, and each finger cylinder 473 is installed with a clamp 476 for clamping the spark plug. The inner side of the clamp 476 is provided with a rubber pad. In the original state, a fixed hand clamp 4751 and four movable hand clamps 4752 are combined together, and the movement of the spacing cylinder 472 drives the bolt to move, and then drives the first movable hand clamp 4752 to move. Since the upper end surface and the lower end surface of the fixed hand clamp 4751 and the movable hand clamp 4752 are respectively connected together through the upper connecting plate 4753 and the lower connecting plate 4754, the first movable hand clamp 4752 will drive the second movable hand clamp 4752, the third movable hand clamp 4752 and the fourth movable hand clamp 4752 to stop at the edge (right) in turn (upper end position). When the second movable hand clamp 4752, the third movable hand clamp 4752 and the fourth movable hand clamp 4752 stop at the edge (left) in turn (lower end position), the distance separation between the material grabbing clamps 475 is achieved. When the grabbing clamp 475 is loading, the distance between the two products is 22 mm. In this way, the distance between the grabbing clamps 475 can be automatically adjusted to 25.3 mm (this is set by the controller, and this distance is optimal). This is also why a material tray is provided on the loading tray 48 of the present invention to avoid waste of the material tray. The material tray can be used to place spark plugs clamped by the upper and lower unloading device 47 (vertically clamping spark plugs).

[0066] The material taking device 2, the cooling device 3 and the unloading and loading device 4 are all connected to a controller, and the automatic operation of the material taking device 2, the cooling device 3 and the unloading and loading device 4 is controlled by the controller.

[0067] When the first photoelectric switch 21 in the present invention detects that there is a spark plug on the mounting seat of the outlet chain plate of the spark plug sintering furnace 1, the first photoelectric switch 21 will notify the controller, and the controller will notify the cylinder 222 on the anti-stripping device 22, and the cylinder 222 will drive the fork 224 to press the mounting seat.
