Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, specifically to an assembly device for a hood and tubing. Background Technology

[0002] In the field of machinery manufacturing and assembly, the assembly of engine covers and fittings is a critical step in the production process of many products, and its assembly quality directly affects the product's performance, sealing performance, and service life. For example, in the production of equipment such as automobile engines and industrial pump bodies, the precise and reliable assembly of engine covers and fittings is of paramount importance.

[0003] Existing assembly methods for machine covers and fittings largely rely on manual operation, which easily leads to glue waste or insufficient application, affecting the sealing effect of the assembly. Furthermore, manual pressing is inefficient and cannot meet the needs of large-scale production. Alternatively, some automated equipment only has single functions such as glue application and fitting conveying, failing to achieve integrated operation of glue application, feeding, and pressing processes. This necessitates the transfer of workpieces between multiple machines during assembly, increasing the complexity and time cost of the production process, and also raising the scrap rate due to workpiece collisions and damage during transfer. Summary of the Invention

[0004] The purpose of this application is to provide an assembly device for machine cover and pipe fittings, which solves the problems of low automation and poor assembly quality in the assembly of machine cover and pipe fittings.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] In a first aspect, this application provides an assembly device for a cover and a pipe, comprising:

[0007] An adhesive applicator is used to apply adhesive to the cover.

[0008] A feeding mechanism for conveying the pipe fitting to the part of the machine cover coated with glue;

[0009] The displacement mechanism includes a first driving member and a slidable sliding member. The sliding member has an adhesive application station and a pressing station. The first driving member is connected to the sliding member and drives the sliding member to switch between the adhesive application station and the pressing station.

[0010] The lifting mechanism includes a second driving member and a support member. The support member is disposed on the sliding member and is used to support the machine cover. When the sliding member is in the pressing position, the second driving member is connected to the support member and drives the support member to rise and fall.

[0011] The pressing mechanism includes a third driving component and a pressing component, wherein the third driving component is connected to the pressing component and drives the pressing component to press the pipe into the machine cover.

[0012] In one embodiment, the support member includes a first support base, a guide rod, and a first connecting base. The guide rod and the first connecting base are both disposed on the first support base, and the guide rod is movably connected to the sliding member.

[0013] The output shaft of the second drive member is connected to a second connecting seat. One of the first connecting seat and the second connecting seat is provided with a slot, and the other of the two is provided with a locking block. When the sliding member is in the pressing position, the locking block is engaged in the slot.

[0014] In one embodiment, the slot is disposed on the first connecting seat, the block is disposed on the second connecting seat, the slot passes through the first connecting seat along a first direction, and the lifting direction of the support member is a second direction;

[0015] In the second direction and / or the third direction, the slot and the card block have a gap, and the first direction, the second direction and the third direction are perpendicular to each other.

[0016] In one embodiment, the assembly device for the cover and the fitting further includes a frame, the frame including a worktable and a support frame, the worktable being provided with a slide rail extending along the first direction, the sliding member being provided with a slide seat and a first through hole, the slide seat being slidably connected to the slide rail, and the first connecting seat passing through the first through hole and connected to the second connecting seat.

[0017] In one embodiment, the glue application mechanism includes a fourth driving member, a mounting base, a glue spinner, and a glue injector. The fourth driving member is mounted on the support frame, and the mounting base is connected to the output shaft of the fourth driving member. The glue spinner and the glue injector are both mounted on the mounting base, and the glue injector is used to inject glue into the glue spinner's spinning tray.

[0018] When the sliding member is in the glue application station, the fourth driving member drives the mounting base to move down so that the glue-spinning disc of the glue-spinning device approaches the machine cover, and the glue-spinning disc of the glue-spinning device rotates to apply glue to the machine cover.

[0019] In one embodiment, the glue application mechanism further includes a fifth driving member and a collection box. The fifth driving member is disposed on the support frame, and the collection box is connected to the output shaft of the fifth driving member. The fifth driving member is connected to the collection box and drives the collection box to move along the third direction, so that the collection box can be located below the glue-spinning disc of the glue-spinning device after the glue-spinning device has finished spinning the glue.

[0020] In one embodiment, the frame further includes a second support base, which is disposed on the worktable and located between the worktable and the support frame. The second support base is provided with a second through hole for the press-fitting component to pass through.

[0021] The second driving member drives the cover on the support member to abut against the second support base, so that the cover communicates with the second through hole;

[0022] The feeding mechanism includes a vibratory feeder, a feed channel, a feeding component, and a sixth driving component. The feed channel is used to receive the pipes transported by the vibratory feeder and convey them to the feeding component. The sixth driving component is connected to the feeding component and drives the feeding component to move, so as to convey the pipes on the feeding component into the second through hole.

[0023] In one embodiment, the feeding mechanism further includes a guide sleeve, one end of which is inserted into the second through hole, and the other end of which is inserted into the machine cover. The inner diameter of the guide sleeve gradually decreases from the end furthest from the machine cover to the end closest to the machine cover.

[0024] In one embodiment, the lifting mechanism further includes a clamping assembly disposed on the first support base. The clamping assembly includes a plurality of clamping members, which are spaced apart in the circumferential direction of the cover.

[0025] In one embodiment, the second support base is provided with a plurality of elastic abutment members, which are arranged circumferentially around the second through hole. Each elastic abutment member includes a retractable mounting sleeve and an abutment head. The mounting sleeve is fixed on the second support base, and the abutment head is used to abut against the cover.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] 1. In this application, an automated assembly process is formed by the coordinated operation of an adhesive application mechanism, a feeding mechanism, a displacement mechanism, a lifting mechanism, and a pressing mechanism. The adhesive application mechanism automatically applies adhesive, the feeding mechanism precisely delivers the pipe fittings, the displacement mechanism automatically switches between the adhesive application and pressing stations, and the lifting and pressing mechanisms work together to press the cover and pipe fittings together. The entire assembly process requires no frequent manual intervention, greatly shortening the assembly time. Compared with traditional manual assembly methods, it can significantly improve production efficiency and meet the needs of large-scale production.

[0028] 2. In this application, the adhesive application mechanism can precisely control the amount and location of adhesive application, ensuring stable and reliable bonding quality between the cover and the fitting. The feeding mechanism can accurately transport the fitting to the designated position, and the displacement and lifting mechanisms can precisely adjust the position and height of the cover, providing good working conditions for the pressing mechanism. Through precise control of the third drive component, the pressing mechanism can press the fitting into the cover with appropriate pressure, avoiding assembly quality problems caused by excessive or insufficient pressure, such as fitting damage or weak bonding, thereby ensuring the quality stability of the entire assembly process.

[0029] 3. In this application, because the entire assembly process is automated, operators only need to be responsible for starting up the equipment, monitoring it, and performing simple maintenance. Complex manual operations such as applying adhesive, handling pipe fittings, and pressing are no longer required, significantly reducing labor intensity. At the same time, it reduces reliance on a large number of skilled workers, lowering the company's labor costs.

[0030] 4. In this application, a snap-fit ​​structure is used to achieve quick docking between the displacement mechanism and the lifting mechanism, so that the support can be displaced under the drive of the first drive to switch between the painting station and the pressing station, and can also be lifted and lowered under the drive of the second drive to cooperate with the pressing mechanism to press the cover and the pipe. This makes the movement of the support relatively independent in the two directions, and suppresses the problem of misalignment of the pipe pressing caused by the skewness of the support.

Detailed Implementation

[0044] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0045] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides an assembly device for machine cover and pipe fitting, for assembling pipe fitting 200 onto machine cover 100. The assembly device includes an adhesive applicator 300, a feeding mechanism 400, a displacement mechanism 500, a lifting mechanism 600, and a pressing mechanism 700.

[0046] The glue application mechanism 300 is used to apply glue to the cover 100. The glue application mechanism 300 is a basic step in the entire assembly process of the cover 100 and the pipe fitting 200, ensuring that the glue can be accurately and appropriately distributed in the designated position of the cover 100, so as to provide bonding conditions for the subsequent assembly of the pipe fitting 200.

[0047] The feeding mechanism 400 is used to transport the pipe fitting 200 to the part of the cover 100 coated with glue, ensuring effective contact between the pipe fitting 200 and the glue on the cover 100, and preparing for the subsequent pressing process.

[0048] The displacement mechanism 500 includes a first driving member 510 and a slidable sliding member 520. The sliding member 520 has an adhesive application station and a pressing station. The first driving member 510 is connected to the sliding member 520 and drives the sliding member 520 to switch between the adhesive application station and the pressing station. Through the driving action of the first driving member 510 itself, the sliding member 520 can switch between these two stations, allowing the entire assembly device to accurately move the cover 100 to the corresponding operating position at different working stages, meeting the needs of different processes such as adhesive application and pressing.

[0049] The lifting mechanism 600 includes a second driving member 610 and a support member 620. The support member 620 is mounted on the sliding member 520 and supports the cover 100. When the sliding member 520 is in the pressing position, the second driving member 610 is connected to the support member 620 and drives the support member 620 to rise and fall. The function of the lifting mechanism 600 is to adjust the height of the cover 100 as needed during the pressing process, ensuring that the pipe 200 can be pressed smoothly and accurately into the cover 100. It can also withstand the impact force during the pressing process, making the cover 100 and the pipe 200 press-fit securely.

[0050] The pressing mechanism 700 includes a third driving component 710 and a pressing component 720. The third driving component 710 is connected to the pressing component 720 and drives the pressing component 720 to press the pipe fitting 200 into the machine cover 100. The pressing mechanism 700 is an execution unit that applies vertical pressure to complete the assembly of the pipe fitting 200. A hydraulic cylinder combined with a pressure head structure can be used to achieve controllable pressure output.

[0051] Specifically, after the cover 100 is fixed to the support 620 of the sliding member 520, the displacement mechanism 500 drives it to move to the gluing station. The cover 100 is provided with a mounting hole 110 for installing the pipe fitting 200, and the gluing mechanism 300 is used to apply glue to the hole wall of the mounting hole 110. Subsequently, the sliding member 520 switches to the pressing station, and the lifting mechanism 600 drives the support 620 to move the cover 100 upward. The feeding mechanism 400 conveys the pipe fitting 200 into the mounting hole 110 on the cover 100, and the pressing member 720 of the pressing mechanism 700 presses down to press the pipe fitting 200 into the mounting hole 110, thereby completing the assembly of the cover 100 and the pipe fitting 200. The entire process achieves seamless connection between the gluing and pressing processes through station switching, avoiding positioning errors caused by multiple clamping of the cover 100.

[0052] In this application, an automated assembly process is formed by the coordinated operation of an adhesive application mechanism 300, a feeding mechanism 400, a displacement mechanism 500, a lifting mechanism 600, and a pressing mechanism 700. The adhesive application mechanism 300 automatically applies adhesive, the feeding mechanism 400 precisely delivers the pipe fitting 200, the displacement mechanism 500 automatically switches between the adhesive application and pressing positions, and the lifting mechanism 600 and the pressing mechanism 700 work together to press the cover 100 and the pipe fitting 200 together. The entire assembly process requires no frequent manual intervention, greatly shortening the assembly time. Compared with traditional manual assembly methods, it can significantly improve production efficiency and meet the needs of large-scale production.

[0053] The adhesive application mechanism 300 precisely controls the amount and location of adhesive application, ensuring stable and reliable bonding quality between the cover 100 and the pipe fitting 200. The feeding mechanism 400 accurately delivers the pipe fitting 200 to the designated position, while the displacement mechanism 500 and lifting mechanism 600 precisely adjust the position and height of the cover 100, providing favorable working conditions for the pressing mechanism 700. Through the precise control of the third drive component 710, the pressing mechanism 700 presses the pipe fitting 200 into the cover 100 with appropriate pressure, avoiding assembly quality problems caused by excessive or insufficient pressure, such as damage to the pipe fitting 200 or weak bonding, thus ensuring the quality stability of the entire assembly process.

[0054] Because the entire assembly process is automated, operators only need to be responsible for starting up the equipment, monitoring it, and performing simple maintenance. They no longer need to perform complex manual operations such as applying adhesive, handling pipe fittings, and pressing, significantly reducing labor intensity. At the same time, it reduces reliance on a large number of skilled workers, lowering the company's labor costs.

[0055] refer to Figures 3-8The support member 620 includes a first support base 621, a guide rod 622, and a first connecting base 623. Both the guide rod 622 and the first connecting base 623 are mounted on the first support base 621. The guide rod 622 is movably connected to the sliding member 520. A second connecting base 611 is connected to the output shaft of the second drive member 610. One of the first connecting base 623 and the second connecting base 611 has a slot 623a, and the other has a locking block 611a. When the sliding member 520 is in the pressing position, the locking block 611a engages with the slot 623a. The guide rod 622 is a rod-shaped structure used to guide the movement trajectory of the sliding member 520, achieving axial sliding by cooperating with a guide hole on the sliding member 520. The first connecting base 623 is a connecting component used to transmit lifting power, specifically fixed to the first support base 621 by bolts. The slot 623a is a recessed structure for accommodating the block 611a. Specifically, it can be a U-shaped slot or a T-shaped slot, and its opening direction matches the movement trajectory of the block 611a. The block 611a is a protruding structure that forms an interlocking fit with the slot 623a. Specifically, it can be a rectangular metal block, which is fixed to the second connecting seat 611 by welding or bolting.

[0056] Specifically, when the sliding member 520 moves to the pressing station, the second driving member 610 drives the second connecting seat 611 to move vertically, so that the locking block 611a and the locking groove 623a on the first connecting seat 623 form an insertion engagement. At this time, the guide rod 622 maintains sliding contact with the guide hole of the sliding member 520, ensuring that the support member 620 does not shift during the lifting process. The second driving member 610 transmits driving force through the locking structure between the second connecting seat 611 and the first connecting seat 623, driving the first support seat 621 and the cover 100 to perform precise lifting actions, providing a stable support reference for the subsequent pressing process.

[0057] This application achieves rapid docking between the displacement mechanism 500 and the lifting mechanism 600 through a snap-fit ​​structure, enabling the support member 620 to move under the drive of the first drive member 510 to switch between the painting station and the pressing station, and to rise and fall under the drive of the second drive member 610 to cooperate with the pressing mechanism 700 to press the cover 100 and the pipe 200. This makes the movement of the support member 620 relatively independent in two directions, suppressing the problem of misalignment of the pipe 200 during pressing due to the skewness of the support member 620.

[0058] In this embodiment, a slot 623a is disposed on a first connecting seat 623, and a locking block 611a is disposed on a second connecting seat 611. The slot 623a penetrates the first connecting seat 623 along a first direction X, and the lifting direction of the support member 620 is a second direction Y. In the second direction Y and / or the third direction Z, the slot 623a and the locking block 611a have gaps, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The slot 623a is a groove structure formed on the first connecting seat 623, specifically a rectangular groove or a dovetail groove, used to accommodate the insertion of the locking block 611a. The locking block 611a is a protrusion structure disposed on the second connecting seat 611, specifically a metal block matching the shape of the slot 623a, used to form a separable locking relationship with the slot 623a. The gap is the space reserved between the inner wall of the slot 623a and the outer surface of the block 611a, allowing the block 611a to be displaced within the slot 623a along the second direction Y or the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged in a mutually orthogonal spatial coordinate layout, with each pair of perpendicular axes. For example, the first direction X is the horizontal longitudinal direction, the second direction Y is the vertical direction, and the third direction Z is the horizontal transverse direction.

[0059] Specifically, when the sliding member 520 moves to the pressing station, the locking block 611a on the second connecting seat 611 inserts into the locking groove 623a of the first connecting seat 623. Since the locking groove 623a passes through the first connecting seat 623 along the first direction X, the locking block 611a can freely enter or exit the locking groove 623a in the first direction X. During the lifting and lowering process of the support member 620, the second driving member 610 drives the first connecting seat 623 to move along the second direction Y through the second connecting seat 611. At this time, the gap between the locking groove 623a and the locking block 611a in the second direction Y or the third direction Z allows the support member 620 to produce a slight offset during lifting and lowering, avoiding rigid collision of the locking part due to processing errors or assembly deviations. It also allows the locking block 611a to smoothly enter and exit the locking groove 623a, which can effectively compensate for the assembly deviation between the first connecting seat 623 and the second connecting seat 611, and avoid wear or deformation of the locking part due to stress concentration.

[0060] The assembly device for the cover and fittings also includes a frame 800, which includes a worktable 810 and a support frame 820. The worktable 810 is provided with a slide rail 811 extending along the first direction X. The sliding member 520 is provided with a slide seat 521 and a first through hole 522. The slide seat 521 is slidably connected to the slide rail 811. The first connecting seat 623 passes through the first through hole 522 and is connected to the second connecting seat 611. The frame 800 is the basic load-bearing structure of the entire device, and can be implemented by welding a metal frame and sheet metal together.

[0061] The worktable 810 is a horizontal support platform of the frame 800. The slide rail 811 is a guide component extending along the first direction X, which can be implemented as a linear guide rail or a V-groove structure, used to constrain the movement trajectory of the sliding member 520. The slide block 521 is a sliding component that cooperates with the slide rail 811, used to reduce the frictional resistance when the sliding member 520 moves. The first through hole 522 is a through hole provided on the sliding member 520, which can be implemented as a circular or rectangular hole structure, used to allow the first connecting seat 623 to pass through and form a connection with the second connecting seat 611.

[0062] Specifically, the slide rail 811 is fixed to the surface of the worktable 810 along the first direction X, and the slide block 521 is connected to the bottom of the sliding member 520 by bolts, allowing the sliding member 520 to reciprocate along the slide rail 811 in the first direction X. The second connecting seat 611 is connected to the second driving member 610 through the first connecting seat 623 passing through the first through hole 522, thereby pushing the support member 620 to rise and fall when the second driving member 610 is activated. The cooperation between the slide rail 811 and the slide block 521 ensures that the sliding member 520 remains stable when switching between the gluing station and the pressing station. The setting of the first through hole 522 ensures that the power transmission path of the lifting mechanism 600 avoids the main structure of the sliding member 520, avoiding motion interference.

[0063] The glue application mechanism 300 includes a fourth drive component 310, a mounting base 320, a glue-spinning device 330, and a glue injector 340. The fourth drive component 310 is mounted on a support frame 820, and the mounting base 320 is connected to the output shaft of the fourth drive component 310. Both the glue-spinning device 330 and the glue injector 340 are mounted on the mounting base 320. The glue injector 340 is used to inject glue into the glue-spinning disc 331 of the glue-spinning device 330. When the sliding member 520 is in the glue application position, the fourth drive component 310 drives the mounting base 320 to move downward, so that the glue-spinning disc 331 of the glue-spinning device 330 approaches the cover 100. The glue-spinning disc 331 of the glue-spinning device 330 rotates to apply glue to the cover 100. The fourth drive component 310 is a power device capable of providing linear motion, which can be implemented by a cylinder or an electric push rod, and is used to control the lifting and lowering action of the mounting base 320. The glue-spinning device 330 is a device with a rotating glue-spinning disc 331, which can be implemented using a high-speed rotating disc structure driven by a motor, and uses centrifugal force to evenly spin out the glue. The glue-dispensing device 340 is a device that can quantitatively deliver glue, which can be implemented using a metering pump or a syringe-type glue-dispensing device, and is used to inject a predetermined amount of glue into the glue-spinning disc 331. The mounting base 320 is a supporting structure for fixing the glue-spinning device 330 and the glue-dispensing device 340, which can be implemented using a metal plate or a frame structure.

[0064] Specifically, when the cover 100 is conveyed to the glue application station, the fourth drive unit 310 pushes the mounting base 320 downwards in the vertical direction, so that the glue-spinning disc 331 of the glue-spinning device 330 is inserted into the mounting hole 110 of the cover 100. The glue injector 340 injects a measured amount of glue into the glue-spinning disc 331, which rotates at high speed under the drive of the motor. Under the action of centrifugal force, the glue is evenly coated on the hole wall of the mounting hole 110 of the cover 100. The lifting and lowering action of the mounting base 320 can prevent the glue-spinning disc 331 from colliding with the cover 100.

[0065] This application controls the lifting and lowering of the mounting base 320 via the fourth drive component 310, which allows for flexible adjustment of the distance between the glue-spraying disc 331 and the machine cover 100, adapting to the glue coating needs of various workpiece specifications. It also achieves automated control of the glue coating process, significantly improving the uniformity of the glue film and avoiding the problem of unstable glue application caused by manual operation.

[0066] The glue application mechanism 300 also includes a fifth drive component 350 and a collection box 360. The fifth drive component 350 is mounted on the support frame 820, and the collection box 360 is connected to the output shaft of the fifth drive component 350. The fifth drive component 350 is connected to the collection box 360 and drives the collection box 360 to move along the third direction Z, so that the collection box 360 is positioned below the glue-spinning disc 331 of the glue-spinning device 330 after the glue-spinning device 330 has finished applying the glue. The fifth drive component 350 is a device for providing linear or rotational power, specifically a cylinder or servo motor. Its output shaft is connected to the collection box 360, thereby controlling the position movement of the collection box 360. After the glue-spinning device 330 completes the glue application, the fourth drive component 310 drives the glue-spinning device 330 to move upwards, and then the fifth drive component 350 is activated, pushing the collection box 360 to move along the third direction Z to directly below the glue-spinning disc 331. At this time, residual glue splashed or dripping from the rotating glue-spraying tray 331 is collected by the collection box 360, preventing glue from contaminating the workbench 810 or the machine cover 100 surface. The position switching of the collection box 360 is synchronized with the glue-spraying action, and it immediately moves to the predetermined position after the glue application stage is completed, ensuring timely glue recovery, reducing the frequency of manual intervention, and improving the cleanliness of the glue application process and overall assembly efficiency.

[0067] In this embodiment, the frame 800 further includes a second support base 830, which is disposed on the workbench 810 and located between the workbench 810 and the support frame 820. The second support base 830 is provided with a second through hole 831 through which the pressing component 720 passes. The second driving component 610 drives the cover 100 on the support component 620 to abut against the second support base 830, so that the cover 100 communicates with the second through hole 831. The feeding mechanism 400 includes a vibratory feeder 410, a feed channel 420, a feeding component 430, and a sixth driving component 440. The feed channel 420 is used to receive the pipe 200 transported by the vibratory feeder 410 and transport it to the feeding component 430. The sixth driving component 440 is connected to the feeding component 430 and drives the feeding component 430 to move so as to transport the pipe 200 on the feeding component 430 into the second through hole 831.

[0068] The second support base 830 is a supporting structure located between the workbench 810 and the support frame 820, providing support for the upper part of the cover 100 during the pressing process. The vibratory feeder 410 is a feeding device with directional sorting function, specifically using electromagnetic drive to automatically arrange and convey the pipe fittings 200, solving the problem of low efficiency in manual feeding. The material channel 420 is a transmission channel connecting the vibratory feeder 410 and the feeding component 430, specifically employing a curved slide rail 811 structure, utilizing gravity to assist the pipe fittings 200 in sliding to the feeding component 430. The sixth driving component 440 is a power element that drives the feeding component 430 to perform linear motion, specifically employing a cylinder or electric push rod. The second through hole 831 is a guide channel penetrating the second support base 830, with an inner diameter slightly larger than the outer diameter of the pipe fitting 200, used to guide the pipe fitting 200 into the mounting hole 110 of the cover 100.

[0069] Specifically, when the cover 100 is lifted by the lifting mechanism 600 to abut against the bottom of the second support 830, the second through hole 831 and the mounting hole of the cover 100 are coaxially aligned. The vibratory feeder 410 automatically sorts the randomly stacked pipes 200 and then conveys them one by one through the material channel 420 into the feeding hole 431 of the feeding member 430. The sixth drive member 440 pushes the feeding member 430 along a predetermined trajectory, causing the pipes 200 to fall from the feeding hole 431 into the second through hole 831 and through the second through hole 831 into the mounting hole 110 of the cover 100. During this process, the second support 830 not only provides a stable support plane for the cover 100 but also constrains the falling path of the pipes 200 through the second through hole 831, preventing the pipes 200 from shifting during transport.

[0070] This application achieves automated connection between the conveying and pressing processes of the pipe fitting 200 through the automatic sorting and conveying of the vibratory feeder 410 and the material channel 420, combined with the feeding component 430 driven by the sixth driving component 440, thus eliminating positioning errors caused by manual operation. The synergistic effect of the second support 830 and the feeding mechanism 400 ensures that the pipe fitting 200 can accurately enter the mounting hole 110 of the cover 100, avoiding pressing failure caused by tilting or offset of the pipe fitting 200.

[0071] refer to Figure 5 , Figure 8 , Figure 9 and Figure 10 The feeding mechanism 400 also includes a guide sleeve 450. One end of the guide sleeve 450 is inserted into the second through hole 831, and the other end is inserted into the cover 100. The inner diameter of the guide sleeve 450 gradually decreases from the end furthest from the cover 100 to the end closest to the cover 100. The guide sleeve 450 is a tubular structure with a tapered inner hole. This structure guides the movement trajectory of the pipe fitting 200 during conveying, allowing the pipe fitting 200 to automatically adjust its position before entering the cover 100, ensuring alignment with the mounting hole 110 of the cover 100.

[0072] Specifically, one end of the guide sleeve 450 is inserted into the second through hole 831 of the second support seat 830, and the other end extends into the mounting hole 110 of the cover 100. When the feeder 430 pushes the pipe 200 into the guide sleeve 450, the pipe 200 first enters the end with the larger inner diameter and gradually moves towards the smaller diameter end as the conveying process progresses. Due to the continuous change in inner diameter, the pipe 200 is radially constrained during its movement, and its axis gradually coincides with the axis of the mounting hole 110 on the cover 100. During the pressing stage, the smaller diameter end of the guide sleeve 450 fits tightly with the hole wall of the mounting hole 110 of the cover 100, forming a positioning reference to ensure that the pipe 200 is pressed into the cover 100 along a predetermined path, thereby improving the pressing accuracy of the pipe 200 and the cover 100.

[0073] The lifting mechanism 600 also includes a clamping assembly 630, which is mounted on the first support base 621. The clamping assembly 630 includes multiple clamping elements 631, which are spaced apart circumferentially on the cover 100. The clamping assembly 630 is a device for fixing the position of the cover 100, and can be implemented using pneumatic grippers or mechanical clamps. The opening and closing action of the clamping elements 631 constrains the edges of the cover 100. The clamping elements 631 are components that directly contact the cover 100 and apply clamping force; they can be implemented using metal clamps with rubber contact surfaces to prevent scratching the surface of the cover 100. The multiple clamping elements 631 spaced apart circumferentially form multi-point positioning, suppressing rotational displacement of the cover 100 during assembly.

[0074] Specifically, when the support member 620 moves up and down under the action of the second drive member 610, multiple clamping members 631 in the clamping assembly 630 act synchronously on the outer edge of the cover 100. During the lifting process, the clamping members 631 remain in a closed state, and the circumferentially distributed clamping force counteracts any lateral displacement that the cover 100 may experience. When the cover 100 is lifted to contact the second support seat 830, the clamping members 631 continue to maintain the clamping state to prevent the cover 100 from rotating or shifting due to force during the pressing process. After the pressing is completed, the clamping members 631 release the clamping state to allow the assembled cover 100 to be removed.

[0075] In one embodiment, the second support base 830 is provided with a plurality of elastic abutment members 840, which are arranged circumferentially around the second through hole 831. Each elastic abutment member 840 includes a telescopically connected mounting sleeve 841 and an abutment head 842. The mounting sleeve 841 is fixed to the second support base 830, and the abutment head 842 is used to abut against the cover 100. The elastic abutment member 840 is a component that achieves buffered contact through a telescopic structure, specifically by employing a spring and sleeve combination. The abutment head 842 adapts to changes in the surface shape of the cover 100 through telescopic movement and provides buffering for the contact between the cover 100 and the second support base 830.

[0076] Specifically, when the second driving member 610 drives the cover 100 on the support member 620 to rise and contact the second support seat 830, the outer edge of the cover 100 contacts the abutment joints 842 of multiple elastic abutment members 840. Because the abutment joints 842 and the mounting sleeve 841 adopt a telescopic connection structure, during the pressing process of the cover 100, the abutment joints 842 can adaptively expand and contract according to the surface shape of the cover 100, avoiding localized stress concentration caused by rigid contact. Simultaneously, the circumferentially distributed elastic abutment members 840 form an annular support area, keeping the cover 100 horizontal during the pressing process and preventing displacement or deformation due to uneven force.

[0077] This application, by setting multiple elastic abutment members 840, can effectively eliminate the risk of hard collision between the cover 100 and the second support 830, reduce the problem of misalignment of the pipe fitting 200 caused by the pressure deformation of the cover 100, and improve assembly accuracy and product qualification rate. The adaptive adjustment function of the elastic abutment members 840 can be compatible with cover 100 of different sizes or with slight deformation, reducing the dependence on the machining accuracy of the cover 100.

[0078] The assembly device for the cover and fittings provided in this application integrates multiple functional mechanisms, including an adhesive applicator 300, a feeding mechanism 400, a displacement mechanism 500, a lifting mechanism 600, and a pressing mechanism 700. Each mechanism operates automatically according to a preset program, requiring no frequent manual intervention. This achieves continuous automated production of the assembly of the cover 100 and fittings 200, significantly shortening the assembly cycle and improving production efficiency. The first drive component 510 of the displacement mechanism 500 drives the sliding component 520 to accurately switch between the adhesive applicator station and the pressing station, ensuring that the adhesive applicator and pressing operations are performed in the correct positions, thus improving the positioning accuracy of the assembly. One end of the guide sleeve 450 of the feeding mechanism 400 is inserted into the second through hole 831, and the other end is inserted into the cover 100, with its inner diameter gradually decreasing. This provides precise guidance for the fittings 200 to enter the cover 100, preventing the fittings 200 from shifting during the pressing process and ensuring the assembly accuracy of the fittings 200 and the cover 100. The elastic abutment member 840 on the second support seat 830 is arranged circumferentially around the second through hole 831. When the lifting mechanism 600 drives the cover 100 to abut against the second support seat 830, the elastic abutment member 840 can provide uniform elastic support force, so that the cover 100 remains stable during the press-fitting process, and further improves the assembly quality of the cover 100 and the pipe fitting 200.
