Description

Technical Field

[0001] This invention relates to the field of engine parts manufacturing and assembly technology, and in particular to a continuous assembly equipment for engine bends and sealing rings. Background Technology

[0002] The Volkswagen EA211C6 1.5T air duct bend, as an important component of the automotive engine, mainly consists of a sealing ring and an injection-molded bend. (Refer to...) Figure 1 The injection-molded bend includes two pipe parts 1, left and right. A buckle 12 is integrally formed on the outer wall of either end of the left or right pipe part. A groove adapted to the buckle 12 is provided on the outer wall of the other pipe part 1. The two pipe parts 1 are connected by the buckle 12 and the groove and other connecting parts. At the connection position, the left and right pipe parts are provided with mounting grooves 11 for embedding sealing rings on the inner wall edge of the pipe part 1. There are two sealing rings, which overlap and fill the connection position of the two pipe parts 1 of the bend.

[0003] Currently, the assembly process for this product is entirely manual, using auxiliary tooling. During assembly, the sealing ring is manually oiled and assembled, and then auxiliary tooling is used to apply force to press the two parts of the pipe fitting 1 together, causing them to snap together at the joint. However, in this manual assembly process, there is a high probability that the assembly is carried out while the injection-molded product is still cooling. This makes it easy for the clips 12 on the pipe fitting 1 to break at the connection point during assembly. It also easily leads to defective products failing the airtightness test due to the omission of the sealing ring. As a result, the manual assembly process results in a low product qualification rate, a high product scrap rate, and high labor intensity for workers, leading to high input costs. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, the present invention provides a continuous assembly device for engine bends and sealing rings.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A continuous assembly device for engine pipe bending and sealing rings is provided, including a frame, a first mounting seat for placing a left pipe and a right pipe on the frame, the first mounting seat being horizontally slidably mounted on the frame, a vibratory feeder for placing and conveying the sealing ring on both sides of the frame, a material dropping seat and a spreading assembly being sequentially arranged on both sides of the sliding path of the first mounting seat on the frame, the discharge end of the vibratory feeder being connected to the material dropping seat, the spreading assembly being used to expand the sealing ring, a first gripping assembly for gripping the sealing ring and moving it between the material dropping seat and the spreading assembly being arranged on the frame, and a second gripping assembly for gripping the sealing ring from the spreading assembly and fitting it onto the pipe, and a pressing assembly for bringing the left and right pipes closer together and connecting them into a product on the first mounting seat.

[0007] Furthermore, the expansion assembly includes a second mounting base, on which a plurality of support blocks for abutting against the inner ring of the sealing ring are evenly spaced around the circumference. The second mounting base is provided with a first driving member for driving the plurality of support blocks to slide synchronously along the radial direction of the second mounting base, so that they move closer to or further away from each other.

[0008] Furthermore, the first gripping component includes a first mounting frame slidably mounted on the frame along the arrangement direction of the material drop seat and the spreading component. The frame is provided with a first driving cylinder for driving the first mounting frame to slide. A first movable frame is vertically slidably connected to the first mounting frame via a second driving cylinder. The bottom of the first movable frame is provided with a first electric gripper and at least two vacuum suction heads, which are arranged in a circumferential manner.

[0009] Furthermore, the second gripping assembly includes a second mounting frame slidably mounted on the frame between the spreading assembly and the first mounting base moving path. The frame is provided with a third drive cylinder for driving the second mounting frame to move. A fourth drive cylinder is rotatably connected to the second mounting frame via a first rotary cylinder. The piston rod end of the fourth drive cylinder is connected to a second movable frame. A rubber ring seat is provided on the second movable frame. The outer wall of the rubber ring seat is provided with a connecting step for the sealing ring to be fitted.

[0010] Furthermore, the pressing assembly includes a fifth drive cylinder. The first mounting base is provided with a left mounting base for installing the left pipe fitting and a right mounting base for installing the right pipe fitting. The right mounting base is slidably connected to the first mounting base. The fifth drive cylinder is disposed on the first mounting base to drive the right mounting base to slide closer to / away from the left mounting base.

[0011] Furthermore, the pressing assembly also includes a pressing fastener, which includes a fixed fastener and a movable fastener. A fixed cylinder and a movable cylinder are provided on the frame. The fixed cylinder is used to drive the fixed fastener to descend vertically and engage with the left pipe on the left mounting seat. The movable cylinder is slidably mounted on the frame parallel to the sliding direction of the right mounting seat. The movable cylinder is used to drive the movable fastener to descend vertically and engage with the right pipe on the right mounting seat.

[0012] Furthermore, both the left and right mounting bases are rotatably connected to pipe fitting seats via a second rotary cylinder for installing pipe fittings.

[0013] Furthermore, a first linear screw module is horizontally arranged on the frame, and a first mounting base is slidably connected to the frame through the first linear screw module.

[0014] Furthermore, a third mounting base is provided on the frame, which is located above the first mounting base. The third mounting base is provided with a transfer base for receiving the left and right pipe fittings taken out of the forming machine by the robot arm. The frame is provided with a third gripping component for gripping the pipe fittings from the third mounting base and transferring them to the first mounting base.

[0015] Furthermore, the third gripping component includes a third mounting frame, on which a second linear screw module is vertically mounted. The third mounting frame is vertically slidably mounted on the frame via the second linear screw module. The third mounting frame is equipped with two sets of second electric grippers, which are used to grip the pipe fittings.

[0016] The beneficial effects of this invention are as follows: After injection molding, the pipe fittings are directly and promptly transferred to the assembly equipment (before the product cools down). The left and right pipe fittings are installed on the first mounting base, and the sealing rings are poured into the vibratory feeder. Lubricating oil is sprayed into the vibratory feeder. As the sealing rings are sent out one by one in the vibratory feeder, they are evenly coated with lubricating oil on their own surface. After the sealing rings move to the material drop seat, they are gripped by the first gripping component and then by the spreading component. The sealing rings are expanded and pressure-held to shape. During the horizontal sliding of the first mounting base on the frame, the second gripping component grips the expanded sealing rings and presses them into the mounting groove of the sealing ring at the end of the pipe fitting. Finally, the first mounting base moves to the pressing component and moves the left and right pipe fittings closer together until the left and right pipe fittings are fitted together to form the product. While the pipe fittings still have a relatively high temperature after injection molding, the pipe fittings are assembled. This effectively avoids the breakage of the snap-fit ​​connection on the pipe fittings and effectively avoids the situation of missing sealing rings or forgetting to apply oil to the sealing rings in the product, thus improving the yield rate.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This invention provides a continuous assembly device for engine pipe bending and sealing rings, including a frame 2. A first mounting seat 3 is provided on the frame 2, sliding along the horizontal X-axis. A left mounting seat 31 and a right mounting seat 32 are sequentially arranged along the horizontal Y-axis on the first mounting seat 3, respectively supporting the left and right pipe fittings in the product being installed. Vibratory feeders 4 are provided on both sides of the frame 2, each containing a sealing ring to be installed. Material droppers 41 are provided on both sides of the sliding path of the first mounting seat 3 on the frame 2. The discharge end of the vibratory feeder 4 is connected to the top of the material dropper 41 via a discharge track, allowing the sealing rings vibrating and being fed out one by one by the vibratory feeder 4 to fall onto the material dropper 41.

[0028] On the frame 2, on both sides of the sliding path of the first mounting seat 3, there are also spreading components 6. On the frame 2, above the material drop seat 41, there is a first gripping component 5. The first gripping component 5 is used to grip the sealing ring from the material drop seat 41 and move it to place it in the spreading component 6. The spreading component 6 is used to expand the sealing ring. The frame 2 is also provided with a second gripping component 7 for gripping the sealing ring from the spreading component 6 and putting it on the pipe fitting. The first mounting seat 3 is provided with a pressing component 8 for moving any one of the left mounting seat and the right mounting seat 32 or both of them at the same time, so that the left pipe fitting and the right pipe fitting are brought closer to each other and connected to form the product.

[0029] In actual operation, after the worker inserts the sealing ring into the vibratory feeder 4, lubricating oil is poured / sprayed into the vibratory feeder 4. During the vibration feeding process of the vibratory feeder 4 into the frame 2, the surface of the sealing ring inside the vibratory feeder 4 is also evenly coated with lubricating oil. However, in the traditional manual installation of sealing rings, it is easy for the sealing ring to be missed or unevenly coated with oil, resulting in some areas of the sealing ring without lubricating oil. When the two pipe fittings are squeezed together later, the parts of the sealing ring without lubricating oil are easily squeezed out, or the sealing ring is exposed outside the joint of the pipe fittings on the product, causing the product to fail to seal at the joint, resulting in product scrap or product defects.

[0030] After the left and right pipe fittings to be installed are placed on the first mounting base 3, the first gripping component 5 grips the rubber ring from the material drop seat 41 and places the rubber ring into the spreading component 6. After the spreading component 6 spreads the rubber ring, the second gripping component 7 installs the rubber ring into the pipe fitting. Then, the left and right pipe fittings are moved closer together for compression assembly, thus completing the entire product installation process. There is no need for manual installation and oiling of the sealing ring, which automates the product production, greatly improves production efficiency, ensures product quality, and effectively reduces the scrap rate.

[0031] In this embodiment, a sensor can be installed on the material drop seat 41. The sensor can be a photoelectric sensor or a pressure sensor, used to detect whether a sealing ring exists on the material drop seat 41. The first gripping assembly 5 includes a first mounting frame 51 and a first movable frame 53. The first mounting frame 51 is located above the material drop seat 41 and is horizontally slidably mounted on the frame 2 via a slide rail. A track is provided on the first mounting frame 51 along the Z-axis, and the first movable frame 53 is slidably connected to the track on the first mounting frame 51. A first drive cylinder 52 is fixedly mounted on the frame 2, and the piston rod of the first drive cylinder 52 is fixedly connected to the first mounting frame 51. A second drive cylinder 56 is fixedly mounted on the first mounting frame 51, and the piston rod of the second drive cylinder 56 is fixedly connected to the first movable frame 53.

[0032] The bottom of the first movable frame 53 is connected to a first electric gripper 54 and two vacuum suction heads 55. The first electric gripper 54 and the vacuum suction heads 55 are arranged in a circle. The first electric gripper 54 is used to hold the rubber ring, and the two vacuum suction heads 55 are used to suction the rubber ring away from the first electric gripper 54. Through the first electric gripper 54 and the two vacuum suction heads 55, the rubber ring can be held horizontally and moved.

[0033] The expansion component 6 includes a second mounting base 61, on which a plurality of support blocks 62 are arranged at uniform intervals around the circumference. In this embodiment, there are four support blocks 62. A step 64 is provided on the top wall of each support block 62 away from the center of the circumference. The four support blocks 62 are slidably mounted on the second mounting base 61 along the radial direction of the circumference. The second mounting base 61 is provided with a first driving member for driving the plurality of support blocks 62 to slide synchronously along the radial direction of the second mounting base 61, so as to move closer to or further away from each other. Specifically, a rubber ring is simultaneously fitted onto the step 64 of the four support blocks 62, and the first driving member drives the four support blocks 62 to slide synchronously away, thereby expanding the size of the rubber ring. Specifically, the first driving component includes a first motor 63 and a driving disk (not shown in the figure). The driving disk is provided with vortex teeth. The first motor 63 is used to drive the driving disk to rotate. The second mounting base 61 is provided with a sliding groove for the support block 62 to slide horizontally and linearly within it. The bottom of the support block 62 is provided with teeth that cooperate with the driving disk. The support block 62 meshes with the driving disk. By driving the driving disk to rotate forward and backward by the first motor 63, the four support blocks 62 can be made to move closer or further away synchronously.

[0034] The second gripping component 7 includes a second mounting frame 71 and a second movable frame 75. A track is provided on the frame 2 between the spreading component 6 and the first mounting base 3. The second mounting frame 71 is slidably mounted on the track on the frame 2. A third drive cylinder 72 is provided on the frame 2 to drive the second mounting frame 71 to move. A first rotary cylinder 73 is fixedly mounted on the second mounting bracket 71. The rotation axis of the first rotary cylinder 73 is horizontally set. A fourth drive cylinder 74 is fixedly connected to the output end of the first rotary cylinder 73. The piston rod end of the fourth drive cylinder 74 is fixedly connected to the second movable bracket 75. A rubber ring seat 76 is provided on the second movable bracket 75. A connecting step 761 for the sealing ring to be fitted is provided on the outer wall of the rubber ring seat 76. The size of the connecting step 761 should be smaller than the inner diameter of the pipe fitting. The pipe fitting has an installation groove 11 at the rubber ring installation position, and a raised ring is provided at intervals on the side of the installation groove 11 near the outside of the pipe fitting to abut against the side wall of the rubber ring facing the outside of the pipe fitting. A clearance groove 762 is opened on the rubber ring seat 76 to allow the support block 62 to pass through.

[0035] After the expansion component 6 expands the rubber ring, the first gripping component 5 moves away, and the second gripping component 7 moves above the expansion component 6. The first rotary cylinder 73 rotates until the second movable frame 75 and the rubber ring seat 76 are vertically aligned with the expansion component 6. The third drive cylinder 72 drives the rubber ring seat 76 to descend and inserts the connecting step 761 into the rubber ring. The four support blocks 62 on the expansion component 6 move and tighten into the relief groove 762 on the rubber ring seat 76, so that the sealing ring is fitted onto the connecting step 761 on the rubber ring seat 76. Next, the first rotary cylinder 73 and the third drive cylinder 72, etc., move to align the rubber ring seat 76 with the end opening of the pipe fitting, push the rubber ring seat 76 into the end opening of the pipe fitting, push the rubber ring into the mounting groove 11 inside the pipe fitting and between the convex ring. Then, the rubber ring seat 76 is removed from the pipe fitting, and the rubber ring is removed from the connecting step 761 on the rubber ring seat 76 through the convex ring inside the pipe fitting, thus completing the installation of the rubber ring. An auxiliary clamping cylinder 22 is also fixed on the frame 2. The auxiliary clamping cylinder 22 is set vertically, and its piston rod end is connected to a clamping block 23. When the pipe fitting on the first mounting seat 3 is being installed into the sealing ring, the auxiliary clamping cylinder 22 can push the clamping block 23 to clamp and fix the pipe fitting on the first mounting seat 3, so as to report the installation quality of the sealing ring.

[0036] The pressing assembly 8 may include a fifth drive cylinder 81. A left mounting seat 31 is fixedly connected to the first mounting seat 3, and a right mounting seat 32 is slidably mounted on the first mounting seat 3 along the horizontal Y-axis. The fifth drive cylinder 81 is fixedly mounted on the first mounting seat 3, and its piston rod is fixedly connected to the right mounting seat 32. When connecting the left and right pipe fittings, the right mounting seat 32 is moved closer to the left mounting seat 31 to connect the left and right pipe fittings.

[0037] To improve the stability of the pipe fittings on the left mounting base 31 and right mounting base 32 when connecting the left and right pipe fittings, the pressing assembly 8 also includes a pressing fastener. The pressing fastener includes a fixed fastener 82 and a movable fastener 84, which are located directly above the left mounting base 31 and right mounting base 32, respectively. The frame 2 is equipped with a fixed cylinder 83 and a movable cylinder 85 for driving the fixed fastener 82 and movable fastener 84 to move vertically. The fixed cylinder 83 is fixedly connected to the frame 2, and the movable cylinder 85 is slidably mounted on the frame 2 along the horizontal Y-axis via a sliding seat. After the fixed fastener 82 and movable fastener 84 are pressed onto the left mounting base 31 and right mounting base 32 to fix the left and right pipe fittings, the right mounting base 32 moves on the frame 2, causing the movable fastener 84 to move with the right mounting base 32. Both the fixed fastener 82 and the movable fastener 84 are provided with fastening grooves 86 that are adapted to the left and right pipe fittings, so that the two fasteners can cooperate with the left mounting base 31 and the right mounting base 32 respectively to stably press the pipe fittings together.

[0038] In order to drive the first mounting base 3 to move on the frame 2, a first linear screw module 21 is horizontally arranged on the frame 2. The first linear screw module 21 includes a first screw arranged along the horizontal X-axis. The first screw passes through the first mounting base 3 and is threadedly engaged with the first mounting base 3. A servo motor is installed on the frame 2 to drive the first screw to rotate forward / reverse.

[0039] To enable the second gripping component 7 to quickly and accurately embed the rubber ring into the end of the pipe fitting, in this embodiment, a second rotary cylinder 33 is installed on both the left mounting base 31 and the right mounting base 32. The output end of the second rotary cylinder 33 is connected to a pipe fitting seat 34 for installing the pipe fitting. After the pipe fitting is placed on the pipe fitting seat 34, when the first moving seat moves to one side of the second gripping component 7, the second rotary cylinder 33 drives the pipe fitting seat 34 to rotate, causing the end of the pipe fitting to be fitted with the rubber ring to rotate towards the second gripping component 7. After the rubber ring is installed, the pipe fitting seat 34 rotates again until the ends of the left and right pipe fittings that need to be connected are aligned, so that the pressing component 8 can connect the two pipe fittings into a product, thereby improving production efficiency.

[0040] In existing manual product installation operations, the pipe fittings are still hot after injection molding, making it impossible for manual workers to directly press-fit two fittings together. The fittings must be allowed to cool down before connection. However, during actual assembly, this can easily cause jamming between fittings and cracks at the connection point with the outer edge of the pipe opening due to compression, resulting in a high scrap rate (approximately 35%). Therefore, in this embodiment, a continuous assembly equipment is connected downstream of the injection molding machine. After the pipe fittings are injection molded, a robotic arm removes them from the injection molding machine and places them directly on the assembly equipment. Assembly is completed promptly while the fittings are still at a relatively high injection temperature and before they have completely cooled down, reducing the product scrap rate.

[0041] Specifically, the frame 2 is provided with a third mounting base 9, which is located above the first mounting base 3 and is horizontally slidably mounted on the frame 2. A third linear screw module 92 is fixedly mounted on the frame 2, and the output end of the third linear screw module 92 is connected to the third mounting base 9, which can drive the third mounting base 9 to move along the X-axis on the frame 2. By using the third mounting base 9 at a higher position, the range of motion of the robot arm outside the injection molding equipment is satisfied, allowing the robot arm to place the pipe fittings onto the assembly equipment. The third mounting base 9 is equipped with an adapter 91 for receiving the pipe fittings taken out of the molding equipment by the robot arm. The frame 2 is also provided with a third gripping assembly 10 for gripping the pipe fittings from the third mounting base 9 and transferring them to the first mounting base 3.

[0042] The third gripping component 10 includes a third mounting frame 101, which is vertically slidably mounted on the frame 2. A second linear screw module 102 is vertically mounted on the frame 2. The second linear screw module 102 includes a second screw and a second servo motor that drives the second screw to rotate. The second screw is set along the Z-axis and rotatably connected to the frame 2. The second screw passes through the third mounting frame 101 and is rotatably connected to the third mounting frame 101. Two sets of second electric grippers 103 are fixedly mounted on the third mounting frame 101. The two sets of second electric grippers 103 are directly opposite to the two adapter seats 91 on the first mounting base 3. The frame 2 has a clearance opening 93 for the third mounting frame 101 and the second electric grippers 103 to grip the pipe fitting vertically and move up and down. After the third mounting frame 101 rises and clamps the pipe fitting on the adapter seat 91, the adapter seat 91 moves away from under the second electric grippers 103, and the third mounting base 91 descends to place the pipe fitting on the first mounting base 3.

[0043] The adapter 91 can be connected to the third mounting bracket 101 via the seventh drive cylinder, allowing the adapter 91 to be raised and lowered vertically. On one side of the adapter 91, the third rotary cylinder can be horizontally slidably connected via the eighth drive cylinder. The output end of the third rotary cylinder is connected to the third electric gripper, which can be used to flip the pipe fittings on the adapter 91. The pipe fittings can be rotated to an angle that matches the pipe fitting seat 34 on the first mounting bracket 3, thereby improving the automation of pipe fitting assembly.

[0044] Those skilled in the art will understand that although preferred embodiments of the invention have been described, those skilled in the art, once they understand the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention. Clearly, those skilled in the art can make various alterations and modifications to the invention without departing from its spirit and scope. Thus, if these modifications and modifications of the invention fall within the scope of the claims of the invention and their equivalents, the invention also intends to include these modifications and modifications.
