TECHNICAL FIELD
[0001] The present application relates to the field of engine cylinder block manufacturing, and particularly relates to an engine cylinder block production system. BACKGROUND
[0002] The engine cylinder block is an important part of the automobile, and in the cylinder block blank manufactured by the casting equipment, the rear side of the cylinder block blank is connected with a handle, and the front side is connected with a plurality of pressure reduction strips, a water gap and a slag ladle. In order to improve the production efficiency, the existing enterprises will adopt an automatic production line for processing, such as the engine cylinder block assembly line provided in the patent (CN 111644598A). The water gap removing device and the handle removing device of the engine cylinder block assembly line have a long stroke, so a sliding block (i.e. a trolley) and a driving mechanism are used to convey the cylinder block blank. Specifically, a conveying slide rail is arranged on a conveying rack, the wheels of the sliding block are connected with the conveying slide rail for walking, a sliding motor drives the first conveying chain to rotate circularly, then the pin of the telescopic device is inserted into the connecting hole of the trolley, so that the first conveying chain 60' drives the sliding block to move. The protective cover covers the first conveying chain to prevent the aluminum scraps on the cylinder block blank from falling onto the first conveying chain. In fact, the slag ladle collecting vehicle is placed in front of the protective cover at the water gap removing station, and the water gap and the slag ladle removed by the second stacking machine hand will slide into the slag ladle collecting vehicle under the guidance of the dust cover (i.e. the inclined guide plate) on the sliding block.
[0003] However, the following problems are found in the production of the above-mentioned engine cylinder block assembly line: 1. The protective cover occupies the slag ladle collecting space, which not only makes it difficult for the slag ladle collecting vehicle to collect the water gap and the slag ladle, but also makes the inclination angle of the dust cover not enough, so that the water gap and the slag ladle are not easy to slide into the slag ladle collecting vehicle and are easy to accumulate on the dust cover. 2. Although the dust cover on the sliding block prevents the aluminum scraps and the slag ladle from falling onto the conveying slide rail, when the dust cover accumulates the slag ladle, the aluminum scraps and the slag ladle are easy to fall into the conveying slide rail due to the scattering of the slag ladle caused by the reciprocating movement of the dust cover, so that the sliding block (i.e. the trolley) is blocked and cannot move. 3. The water gap removing device and the handle removing device are arranged side by side, which occupies a large area. In order to avoid the production line being too long, the cylinder block feeding line and the cylinder block discharging line are shortened, so that the number of cylinder block blanks that can be buffered by the cylinder block feeding line is small.
[0004] It can be seen that the insufficient falling space of the slag ladle and the water gap will cause production failure, so it is urgent to improve the existing engine cylinder block assembly line. SUMMARY

[0017] Beneficial effects:
[0018] The engine block production system provided by this invention improves the cylinder block drain port and material handle device, merging the original drain port device and material handle device into a waste processing station, which greatly reduces the space occupied by the equipment, thereby extending the configuration of the cylinder block feeding line and increasing the number of cylinder block buffers.
[0019] Furthermore, the cylinder blank can be transferred through the cooperation of the slide rail and the cylinder pushing mechanism. The structure is lightweight and easy to maintain, replacing the complex transfer method of using a chain drive mechanism to pull a trolley to transport the cylinder blank. Since the space of the original chain conveying mechanism is also eliminated after the trolley is eliminated, the space for the slag bag and slag bag to fall and the collection space are increased. This allows the slag bag collection car to be placed directly below the slag bag and slag bag striking station to collect the slag bag and slag bag. Most of the slag bag and slag bag can fall directly into the slag bag collection car. Even if a small part of the slag bag and slag bag falls onto the slide rail, the smooth slide rail makes it easy for the waste to slide into the slag bag collection car, greatly reducing the accumulation of waste.

Detailed Implementation
[0036] This invention provides an engine block production system. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.
[0037] Please see Figure 1 This invention provides an engine block production system, which includes a cylinder liner feeding device 1, a cylinder liner transfer device 2, a casting equipment 3, a cylinder block feeding line 4, a sprue and material handle device 5, and a cylinder block unloading line 6, which are sequentially connected from upstream to downstream of the processing. The cylinder liner feeding device 1 is used to provide cylinder liners 92 to the cylinder liner transfer device 2. The cylinder liner transfer device 2 is used to transfer a set number of cylinder liners 92 to the die casting area 93. The casting equipment 3 is used to cast the set number of cylinder liners 92 into an integral cylinder block blank 91.
[0038] For details, see Figures 2-6 As shown, the drain outlet and material handle device 5 includes a transfer frame 51, a slag bag collection vehicle 511 located in front of the transfer frame 51, a first multi-axis robot 50 located in front of the slag bag collection vehicle 511, a waste vehicle 7 located next to the first multi-axis robot 50, a conveyor base 52 located on the transfer frame 51, a pre-compression mechanism 53, a stamping mechanism 54, and a cylinder pushing mechanism 55. Two laterally extending slide rails 571 and a guide bar 572 located between the two slide rails 571 are fixed on the conveyor base 52. The two slide rails 571 connect the cylinder loading line 4 and the cylinder. The cylinder unloading line 6 has a processing station 575 on the slide rail 571. The cylinder pushing mechanism 55 is used to push the cylinder blank 91 on the cylinder loading line 4 to the processing station 575 and to push the cylinder blank 91 at the processing station 575 to the cylinder unloading line 6. The pre-pressing mechanism 53 is located above the guide bar 572 and is used to press the cylinder blank 91 onto the slide rail 571. The stamping mechanism 54 is located behind the pre-pressing mechanism 53 and is used to press the material handle on the cylinder blank 91 off. The clamping end of the first multi-axis robot 50 is equipped with a water outlet assembly.
[0039] The production process of the engine block is as follows: The cylinder liner feeding device 1 first transports each cylinder liner 92 to the cylinder liner transfer device 2. When the cylinder liner transfer device 2 has a set number (such as 3 or 4) of cylinder liners 92, the cylinder liner transfer device 2 is used to transfer the set number of cylinder liners 92 to the die casting area 93. Then, the cylinder liners are transported to the mold of the casting equipment 3 by manual or automatic gripping, and then die-cast to obtain the cylinder block blank 91. The rear side of the cylinder blank 91 is connected to a material handle, and the front side is connected to several pressure reducing strips, a water inlet, and a slag bag. The cylinder blank is then transported to the cylinder loading line 4 for buffering and orderly movement to the right. When the cylinder loading line 4 transports the cylinder blank to its tail end, the conveying stops. The cylinder pushing mechanism 55 pushes the cylinder blank from the cylinder loading line 4 to the cylinder pre-pressing station 575 on the slide rail 571. The cylinder blank 91 slides smoothly on the slide rail 571 with low resistance, and under the guidance of the guide bar 572, the lateral conveying direction of the cylinder blank 91 is ensured to be accurate. Then, the pre-pressing mechanism 53 presses the cylinder blank at the cylinder pre-pressing station 575... The cylinder blank 91 is pressed onto the slide rail 571. At this time, the sprue and slag bag of the cylinder blank 91 face forward, and the material handle of the cylinder blank 91 faces backward. Then, the first multi-axis robot 50 first uses the sprue removal assembly to remove the pressure relief strip on the cylinder blank 91. The removed pressure relief strip is placed into the waste cart 7. Then, the sprue and slag bag on the cylinder blank 91 are knocked off. The sprue and slag bag fall directly into the slag bag collection cart 511 or fall onto the slag bag slide plate 573 and then slide into the slag bag collection cart 511 for collection. Subsequently, the stamping mechanism 54 stamps and removes the material handle on the cylinder blank. Finally, the cylinder pushing mechanism 55 pushes the cylinder blank on the slide rail 571 onto the cylinder unloading line 6.
[0040] Compared with the prior art, the engine block production system provided by this invention improves the cylinder block drain port and material handle device 5, merging the original drain port device and material handle device into a single waste processing station, greatly reducing the space occupied by the equipment. This allows for an extended cylinder block loading line 4 and an increase in the number of cylinder block buffers. Furthermore, the cylinder block blanks can be conveyed through the cooperation of the slide rail 571 and the cylinder block pushing mechanism 55. The structure is lightweight and easy to maintain, replacing the complex conveying method of using a chain drive mechanism to pull a trolley to transport cylinder block blanks. In other words, this invention eliminates the need for components such as sliders, drive mechanisms, protective covers, and conveyor slide rails in existing engine block production systems, fundamentally solving all the technical problems described in the background art. Since the trolley was removed, the space of the original chain conveyor mechanism was also removed, which indirectly increased the space for the slag bag and sprue to fall and the collection space. This allows the slag bag collection car 511 to be placed directly below the sprue and slag bag striking station to collect the sprue and slag bag. Most of the sprue and slag bags can fall directly into the slag bag collection car 511. Even if a small number of sprue and slag bags fall onto the slide rail 571, the smooth slide rail 571 makes it easy for the waste to slide off, greatly reducing the accumulation of waste.
[0041] Analysis of existing engine block assembly line faults revealed that small slag bales easily get stuck on the rollers and slide bars of the trolley, making it difficult for the cylinder block blank to be smoothly transferred / leaved from the trolley, and the rollers and slide bars are also prone to damage. Therefore, this invention provides a cylindrical slide rail 571. The bottom of the slide rail 571 has an axially extending mounting groove 5711, and the bottom surface of the mounting groove 5711 has a threaded hole. The conveyor base 52 and the slide rail 571 are connected by screws and threaded holes, resulting in a simple structure that is easy to replace and maintain. Both ends of the slide rail 571 have connecting inclined surfaces 5712, facilitating the bottom of the cylinder block blank 91 to be introduced / extracted from the slide rail 571. The cylindrical slide rail 571 not only works in conjunction with the guide bar 572 to support the cylinder block blank 91, but also has low sliding friction with the cylinder block blank 91 and features a rounded outer wall, making it difficult for waste material to accumulate. Similarly, the guide bar 572 also has a rounded outer wall, making it difficult for waste material to accumulate.
[0042] For preferred options, please refer to [link / reference]. Figure 3 and Figure 6 The conveyor base 52 is equipped with a slag bag slide plate 573 and a waste slide plate 574, which are inclined towards the slag bag collection vehicle 511. The waste slide plate 574 is located below the guide bar 572, and the slag bag slide plate 573 is located in front of the conveyor base 52. Both the slag bag slide plate 573 and the waste slide plate 574 are used to guide the sprue, slag bag, and aluminum chips into the slag bag collection vehicle 511, preventing waste from flying outwards, so as to achieve a better waste collection effect.
[0043] For details, please refer to Figure 6The conveying base 52 includes two side plates 521, support legs 522 disposed between the two side plates 521, and a reinforcing plate 523. Two support legs 522 are provided and located below the reinforcing plate 523. The reinforcing plate 523 has multiple perforated slots 5231. The waste material slide plate 574 is located between the two support legs 522. Two slide rails 571 are respectively disposed on the top of the corresponding side plates 521. The two ends of the guide strip 572 are mounted on the reinforcing plate 523 via support pillars. With this configuration, the guide strip 572 and slide rails 571 can be suspended. Even if waste material falls between the two slide rails 571, it can fall through the perforated slots 5231 to the ground or onto the waste material slide plate 574, preventing accumulation on the side of the slide rails 571 and guide strips 572, thus avoiding interference with the normal sliding and conveying of the cylinder blank 91.
[0044] See Figures 1-3 As shown, in order to better remove waste, a cylinder pre-pressing station 575 is provided on the slide rail 571. When the cylinder blank 91 slides to the cylinder pre-pressing station 575, the main body of the cylinder blank 91 is pressed onto the slide rail 571 by the pre-pressing mechanism 53. The pre-pressing mechanism 53 includes a second mounting base plate 531 set on the transfer frame 51, a downward pressing cylinder 532 set vertically downward on the top of the first mounting base plate 541, and a pressing block 533 connected to the piston rod end of the downward pressing cylinder 532. The pressing block 533 is located above the guide bar 572. When it is necessary to fix the cylinder blank 91 on the slide rail 571, the downward pressing cylinder 532 drives the pressing block 533 to descend, so that the pressing block 533 presses the cylinder blank 91 to fix the cylinder blank 91.
[0045] In this embodiment, the dewatering nozzle assembly includes a pressure-reducing strip clamp 581 and an impact hammer. The impact hammer is fixedly connected to the first multi-axis robot 50, and the pressure-reducing strip clamp 581 is used to connect to the clamping end of the first multi-axis robot 50. The pressure-reducing strip clamp 581 is provided with a quick connector. The first multi-axis robot 50 can replace the pressure-reducing strip clamp by connecting the quick connector on the pressure-reducing strip clamp via a quick-connect plate. The first multi-axis robot 50 uses the impact hammer to strike the sprue and slag bag on the cylinder blank 91, causing the sprue and slag bag on the cylinder blank to fall off and slide onto the slag bag collection vehicle 511. After the first multi-axis robot 50 is equipped with the pressure-reducing strip clamp 581, it clamps the pressure-reducing strip on the cylinder blank through the pressure-reducing strip clamp 581. Driven by the first multi-axis robot 50, the pressure-reducing strip is clamped by the pressure-reducing strip clamp 581 and pulled back and forth to break it.
[0046] For details, see Figures 3-4As shown, the stamping mechanism 54 includes a first mounting base plate 541 mounted on a transfer frame 51, a servo electric cylinder 542 vertically positioned at the top of the first mounting base plate 541, a stamping rod (not visible in the figure) connected to the output end of the servo electric cylinder 542, and a punch 543 positioned at the bottom of the stamping rod. A guide sleeve 544 is provided at the bottom of the first mounting base plate 541 to guide the vertical movement of the stamping rod. When the stalk needs to be removed, the servo electric cylinder 542 drives the stamping rod to descend, causing the punch 543 to remove the stalk from the cylinder blank 91 fixed by the pre-pressing mechanism 53. Compared with pneumatic stamping, servo stamping offers controllable stamping stroke and allows the pressing and holding time to be set according to actual conditions, ensuring that the stalk falls smoothly onto the stalk transfer mechanism 56 after breaking. It also boasts advantages such as high precision, high speed, and quiet operation.
[0047] For details, please refer to Figure 3 , Figure 4 , Figure 9 as well as Figure 10 The drain outlet and material handle device 5 further includes a material handle transfer mechanism 56 mounted on the transfer frame 51. The material handle transfer mechanism 56 includes a base 561 mounted on the transfer frame 51, a first sliding plate 562 slidably mounted on the top of the base 561, a receiving frame 563 mounted on the first sliding plate 562, a rack 5651 mounted on the base 561, a drive motor 564 vertically mounted on the sliding plate, and a gear 5652 sleeved on the output end of the drive motor 564. The rack 5651 extends laterally, and the rack 5651 and gear 5652... 652 meshing transmission; when the material handle falls onto the receiving rack 563, the drive motor 564, driven by the gear 5652 and rack 5651, moves the first slide plate 562, the receiving rack 563, and the material handle on the receiving rack 563 together to the side of the cylinder blank 91, so that the material handle is away from the cylinder blank 91, the pre-pressing mechanism 53 and the stamping mechanism 54, and the material handle can face the first multi-axis robot 50. Correspondingly, the clamping end of the first multi-axis robot 50 is replaced with a material handle gripper 582, and the first multi-axis robot 50 uses the material handle gripper 582 to grab the material handle onto the scrap cart 7 without obstruction.
[0048] For further details, please refer to Figure 4 and Figure 5A laterally extending cable chain support plate 5691 is provided behind the conveyor base frame 52. A cable chain connecting plate 5692 is provided on the first slide plate 562. A cable chain (not shown in the figure) is provided on the cable chain support plate 5691. The power supply line for supplying power to the drive motor 564 is hidden on the cable chain. One end of the cable chain is fixed to the cable chain support plate 5691, and the other end is fixed to the cable chain connecting plate 5692. A chip chute 5693 is provided on the transfer frame 51 below the cable chain support plate 5691. A chip discharge groove 5694 is provided on the cable chain support plate 5691. Even if aluminum chips or small aluminum pieces fall onto the cable chain when the material handle breaks, the aluminum chips or small aluminum pieces can slide through the chip discharge groove 5694 onto the chip chute 5693, preventing aluminum chips or small aluminum pieces from accumulating on the cable chain and cable chain support plate 5691 and hindering the normal operation of the cable chain. It should be noted that the bottom edge of the debris ramp 5693 is flush with the ground, and the debris will eventually accumulate next to the debris collection vehicle 511, which can be cleaned up periodically.
[0049] Preferably, protective plates 530 are provided on both sides of the pressure block 533. The protective plates 530 are L-shaped and mirror images of each other. After the pressure block 533 presses down to fix the cylinder blank, the two L-shaped protective plates 530 can provide protection from both sides. When the multi-axis second multi-axis robot 131 drives the impact hammer or pressure reducing strip clamp 581 to process the cylinder blank, the protective plates 530 prevent slag bags, sprues, or aluminum chips falling off the cylinder blank from splashing towards the slide rail 571, so as to make the slag bags, sprues, or aluminum chips fall into the slag bag collection cart 511 as much as possible, reducing the accumulation of slag bags, sprues, or aluminum chips. The protective plates 530 can also be driven to the end of the piston rod of the cylinder to achieve the purpose of adjusting the protective position.
[0050] For details, please refer to Figures 2-8 The cylinder block pushing mechanism 55 includes a crossbeam 551 mounted on a transfer frame 51, and a first pushing component 552 and a second pushing component 553 respectively mounted at both ends of the crossbeam 551. The first pushing component 552 and the second pushing component 553 are symmetrically arranged. The first pushing component 552 is used to push the cylinder block blank onto the slide rail 571, and the second pushing component 553 is used to push the cylinder block blank away from the slide rail 571. With this arrangement, the first pushing component 552 and the second pushing component 553 share the crossbeam 551 but do not interfere with each other, making the overall structure of the cylinder block pushing mechanism 55 compact.
[0051] Furthermore, both the first pushing assembly 552 and the second pushing assembly 553 include a first cylinder 5541 mounted on the crossbeam 551, a second slide plate 5542 slidably connected to the crossbeam 551, a rocker arm 5543 pivotally connected to the second slide plate 5542, and a second cylinder 5544 disposed on the second slide plate 5542. The first cylinder 5541 is used to drive the second slide plate 5542 to reciprocate along the length direction of the crossbeam 551. The cylinder body of the second cylinder 5544 is hinged to the second slide plate 5542, and the piston rod end of the second cylinder 5544 is pivotally connected to the rocker arm 5543.
[0052] When the cylinder loading line 4 stops transporting the cylinder blank 91 to the end of the cylinder loading line 4, the second cylinder 5544 on the first pushing assembly 552 pushes the swing rod 5543 to unfold, so that the swing rod 5543 is horizontal and perpendicular to the conveying direction of the cylinder blank 91, that is, the unfolded swing rod 5543 is located on the left side of the cylinder blank. Then, the piston rod of the first cylinder 5541 changes from the retracted state to the extended state. The first cylinder 5541 drives the second slide plate 5542 and the swing rod 5543 to move towards the slide rail 571. The swing rod 5543 first pushes the cylinder blank 91 from the cylinder loading line 4 onto the slide rail 571, and then continues to push the cylinder blank 91 to the cylinder pre-pressing station 575 on the slide rail 571. Then, the first cylinder 5544 on the first pushing assembly 552 pushes the second cylinder blank 91 to the end of the cylinder loading line 4 to the end of the cylinder pre-pressing station 575 on the slide rail 571. 541 and the second cylinder 5544 are reset; after the cylinder blank 91 is cleaned of waste such as sprues, slag bags and material handles, the first cylinder 5541 on the second pushing assembly 553 first drives the piston rod to extend to the limit position, and then the second cylinder 5544 on the second pushing assembly 553 pushes the swing rod 5543 to unfold, so that the swing rod 5543 is horizontal and perpendicular to the conveying direction of the cylinder blank, that is, the unfolded swing rod 5543 is located to the left of the cylinder blank. Then the piston rod of the first cylinder 5541 is reset and retracted, and the swing rod 5543 pushes the cylinder blank to the right, first pushing the cylinder blank 91 away from the cylinder pre-tightening station 575, and then pushing the cylinder blank 91 from the slide rail 571 to the head of the cylinder unloading line 6, successfully transferring the cylinder blank 91 to the cylinder unloading line 6.
[0053] Preferably, the cylinder body of the first cylinder 5541 is fixed on the crossbeam 551. The first cylinder 5541 in the first pushing assembly 552 has a long stroke of 1000mm, which better meets the requirements for long-distance conveying. The first cylinder 5541 in the second pushing assembly 553 has a stroke of 700mm, which is sufficient to push the cylinder blank 91 from the cylinder pre-tightening station 575 to the cylinder unloading line 6.
[0054] For details, please refer to Figure 2The cylinder loading line 4 includes a loading frame 41, a first chain conveyor mechanism 42 and a first collection hopper 43 mounted on the loading frame 41. The first collection hopper 43 is located below the first chain conveyor mechanism 42, and a first waste collection box 44 is provided at the outlet of the first collection hopper 43. The cylinder unloading line 6 includes an unloading frame 61, a second chain conveyor mechanism 62 and a second collection hopper 63 mounted on the unloading frame 61. The second collection hopper 63 is located below the second chain conveyor mechanism 62, and a second waste collection box 64 is provided at the outlet of the second collection hopper 63. After the cylinder body is cast into a cylinder body blank 91 by the casting equipment 3, the cylinder body blank 91 has a lot of aluminum shavings. During the conveying process of the cylinder body blank 91 through the first chain conveyor mechanism 42 and the second chain conveyor mechanism 62, the aluminum shavings on the cylinder body blank 91 are prone to falling off due to vibration and other reasons. Therefore, the aluminum shavings are collected into the first waste collection box 44 and the second waste collection box 64 through the first collection hopper 43 and the second collection hopper 63. The cylinder body blank 91 can be conveyed by placing it on the chains of the first chain conveyor mechanism 42 and the second chain conveyor mechanism 62. It is simple and convenient, and has the advantages of high load-bearing capacity and suitability for harsh working environments. Even if aluminum shavings fall onto the chain, it will not jam the chain and affect its normal operation. Only regular maintenance is required.
[0055] In fact, a large slag blob forms on the rear side of the cylinder block blank, which is difficult to remove using the drain and slurry handle device 5. Therefore, a slag blob removal mechanism 8 is provided next to the first chain conveyor mechanism 42 (see...). Figure 2 , Figure 12 , Figure 13 As shown, the slag bag removal mechanism 8 includes a housing 81 with an upper opening, a rotating shaft 82 rotatably connected to the side wall of the housing 81, and a pendulum 83 fixed on the rotating shaft 82. A transmission assembly 84 is provided inside the housing 81 to drive the rotating shaft 82. The transmission assembly 84 is driven by a cylinder driving the pendulum 83. The pendulum 83 is located outside the housing 81, and the opening of the housing 81 is sealed by a cover plate 86. The pendulum 83 includes a rounded head connecting part and a striking part integrally formed with the rounded head connecting part. The striking part is in the shape of a "7", which can also be understood as a bird's beak shape, forming a pointed head with high striking strength. The rounded head connecting part is sleeved on the rotating shaft 82, and the rounded head connecting part is connected to the rotating shaft 82 by a key. After the cylinder blank is transported to the cylinder loading line 4, when the cylinder blank passes the slag removal mechanism 8 and is located directly in front of the slag removal mechanism 8, the pendulum 83 drives the cylinder cylinder to rotate the shaft 82 under the transmission of the transmission component 84. This causes the pendulum 83 on the shaft 82 to swing rapidly toward the slag on the cylinder blank 91, thereby causing the tip of the hammer to quickly knock off the slag on the cylinder blank. The slag falls into the first collection hopper 43 of the cylinder loading line 4 and is finally collected by the first waste collection box 44.
[0056] In practical applications, the roof of the factory building housing the existing engine block assembly line has windows that allow light to pass through. When the sunlight is too intense, it can easily affect the normal operation of the vision camera 134, causing it to be unable to accurately identify the position of the cylinder liner. Therefore, the cylinder liner loading device 1 needs to be modified. Please refer to... Figure 11 The cylinder liner feeding device 1 provided by the present invention includes a fence 111, in which a cardboard recycling cart 191 and a cylinder liner transport cart 192 are arranged side by side; a vertical frame 112 is provided on the fence 111, and a top frame 113 is provided on the top of the vertical frame 112; a storage platform 12 is fixed on the fence 111, and a second multi-axis transport robot 131 is provided on the storage platform 12; a support arm 132 is installed on the clamping end of the second multi-axis transport robot 131. The support arm 132 is equipped with a quick-change connector 133 and a vision camera 134 located next to the quick-change connector 133. The vertical frame 112 is provided with a clamp placement platform 14. The clamp placement platform 14 is provided with a cylinder liner gripper 15, a layer paper gripper 16, and a separator paper gripper 17 that can be connected to the quick-change connector 133. The top frame 113 is horizontally covered with colored glass 114 for reducing sunlight. The vertical frame 112 is provided with a baffle 115.
[0057] During operation, the second multi-axis transport robot 131 connects to the cylinder liner gripper 15 via a quick-connect coupling 133. The cylinder liner gripper 15, driven by the second multi-axis transport robot 131, enters the cylinder liner transfer carriage 192. Then, the vision camera 134 accurately identifies the position of the cylinder liner to be gripped. Subsequently, the cylinder liner gripper 15 grips the cylinder liner 92, and the second multi-axis transport robot 131 transports the cylinder liner 92 to the cylinder liner transfer device 2. By adding a top frame 113 and tinted glass 114, and utilizing the good light-filtering properties of the tinted glass 114, the technical problem of strong sunlight affecting the normal recognition of the vision camera 134 is solved. Furthermore, the placement platform 12 is located on the side and top of the fence 111, cleverly utilizing the support of the fence 111 for its placement, and also giving the second multi-axis transport robot 131 a height advantage, allowing it to more flexibly enter the cylinder liner transfer carriage 192 for gripping.
[0058] After all cylinder liners 92 on the same layer have been picked up, there are no cylinder liners 92 in any of the cylinder liner placement cavities of the separator paper. The second multi-axis transport robot 131 removes the cylinder liner gripper 15 and connects to the separator paper gripper 17 via quick-change connector 133. After the separator paper gripper 17 picks up the separator paper, it puts the separator paper into the cardboard recycling cart 191. Next, the second multi-axis transport robot 131 removes the separator paper gripper 17 and connects to the layer paper gripper 16 via quick-change connector 133. After the layer paper gripper 16 picks up the layer paper, it puts the layer paper into the cardboard recycling cart 191. At this time, the next layer of cylinder liners 92 to be transported appears in the cylinder liner transport cart 192. Then, the second multi-axis transport robot 131 removes the layer paper gripper 16 and connects to the cylinder liner gripper 15 via quick-change connector 133 to continue the batch transport of cylinder liners 92.
[0059] Furthermore, the tinted glass 114 specifically uses brown or bronze heat-absorbing glass with even lower light transmittance, allowing only 25% of sunlight to pass through.
[0060] For details, please refer to Figure 1 , Figure 14 and Figure 15 The cylinder liner transfer device 2 includes a fixed base plate 21, a fixed shaft 22 vertically arranged on the fixed base plate 21, a sleeve 23 sleeved on the fixed shaft 22 and rotatably connected to the fixed shaft 22, a swing arm 24 fixed on the sleeve 23, and a drive device 25 for driving the sleeve 23 to rotate; the swing arm 24 is horizontally arranged with a support plate 29 and a vertically arranged door plate 26, and the support plate 29 is provided with a plurality of positioning seats 28 for placing cylinder liners and a detection mechanism 27 for detecting whether a cylinder liner is placed on the positioning seat 28.
[0061] When the cylinder liner transfer device 2 is to receive the cylinder liner 92, the drive device 25 drives the sleeve 23 to rotate, so that the pallet 29 and the positioning seat 28 on the swing arm 24 move from the die casting area 93 to the cylinder liner loading device 1. Then the cylinder liner loading device 1 picks up the cylinder liners 92 one by one and places them on the positioning seats 28. When the detection mechanism 27 detects that all the positioning seats 28 are carrying cylinder liners 92, the drive device 25 drives the sleeve 23 to rotate in the opposite direction, so that the pallet 29, the positioning seat 28 and the cylinder liners 92 on the swing arm 24 turn back to the die casting area 93. At the same time, the door panel 26 blocks the connection between the cylinder liner loading device 1 and the die casting area 93. Finally, the second multi-axis robot 131 in the die casting area waits for the cylinder liners to be picked up and placed into the mold of the casting equipment 3 to realize the casting of the cylinder body. In this embodiment, the rotation range of the swing arm 24 is 90°, that is, the transfer path of the positioning seat 28 and the cylinder liner 92 is an arc. Compared with the straight transfer path, it better matches the actual position of the cylinder liner feeding device 1 and the second multi-axis robot 131. That is, the cylinder liner feeding device 1 places the cylinder liner 92 on the positioning seat 28 in a better manner, and the second multi-axis robot 131 grasps the cylinder liner 92 on the positioning seat 28 in a better manner. Therefore, the cylinder liner transfer device 2 provided by this utility model not only realizes the transfer of the cylinder liner 92 in position, but also plays the role of a transfer platform.
