DETAILED DESCRIPTION

[0044] The following are specific embodiments of the present application and further describe the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0045] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The application provides an assembling device of a cover and a pipe fitting, which is used for assembling the pipe fitting 200 on the cover 100, and the assembling device comprises a gluing mechanism 300, a feeding mechanism 400, a displacement mechanism 500, a jacking mechanism 600 and a pressing mechanism 700.

[0046] The gluing mechanism 300 is used for applying glue on the cover 100, and the gluing mechanism 300 is a basic step in the whole assembling process of the cover 100 and the pipe fitting 200, which ensures that the glue can be accurately and appropriately distributed on the specified position of the cover 100, and provides bonding conditions for the subsequent assembly of the pipe fitting 200.

[0047] The feeding mechanism 400 is used for conveying the pipe fitting 200 to the position on the cover 100 where the glue is applied, so as to ensure the effective contact of the pipe fitting 200 with the glue on the cover 100 and to prepare for the subsequent pressing process.

Through the driving action of the first driving member 510, the sliding member 520 can be switched between the two stations, so that the whole assembling device can accurately move the cover 100 to the corresponding operation position in different working stages, and meet the requirements of different processes of gluing and pressing.

[0049] The jacking mechanism 600 comprises a second driving member 610 and a supporting member 620, the supporting member 620 is arranged on the sliding member 520, and the supporting member 620 is used for supporting the cover 100, when the sliding member 520 is in the pressing station, the second driving member 610 is connected with the supporting member 620 and drives the supporting member 620 to lift. The jacking mechanism 600 adjusts the height position of the cover 100 according to the needs in the pressing process, ensures that the pipe fitting 200 can be smoothly and accurately pressed into the cover 100, and can also withstand the impact force in the pressing process, so that the cover 100 and the pipe fitting 200 are stably pressed.

[0050] The pressing mechanism 700 comprises a third driving member 710 and a pressing member 720, the third driving member 710 is connected with the pressing member 720 and drives the pressing member 720 to press the pipe fitting 200 into the cover 100. The pressing mechanism 700 is an execution unit for applying vertical pressure to complete the assembly of the pipe fitting 200, and can realize controllable pressure output by adopting a hydraulic cylinder cooperating with a pressing head structure.

[0051] Specifically, after the cover 100 is fixed on 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 mounting the pipe fitting 200, and the gluing mechanism 300 is used to apply glue to the hole wall of the mounting hole 110. Then the sliding member 520 switches to the pressing station, and the jacking mechanism 600 drives the support 620 to move the cover 100 upward. The feeding mechanism 400 delivers the pipe fitting 200 into the mounting hole 110 on the cover 100, and the pressing member 720 of the pressing mechanism 700 is pressed to press the pipe fitting 200 tightly in the mounting hole 110, so as to complete the assembly of the cover 100 and the pipe fitting 200. The whole process realizes seamless connection of the gluing and pressing processes through station switching, avoiding positioning errors caused by multiple clamping of the cover 100.

[0052] In this application, through the cooperation of the gluing mechanism 300, the feeding mechanism 400, the displacement mechanism 500, the jacking mechanism 600 and the pressing mechanism 700, an automatic assembly process is formed. The gluing mechanism 300 realizes automatic glue application, the feeding mechanism 400 accurately delivers the pipe fitting 200, the displacement mechanism 500 realizes automatic switching of the gluing and pressing stations, the jacking mechanism 600 and the pressing mechanism 700 cooperate to complete the pressing of the cover 100 and the pipe fitting 200, and the whole assembly process does not need frequent manual intervention, greatly shortening the assembly time, significantly improving the production efficiency compared with the traditional manual assembly method, and meeting the needs of large-scale production.

[0053] Among them, the gluing mechanism 300 can accurately control the amount and position of glue application, ensuring the stable and reliable bonding quality between the cover 100 and the pipe fitting 200. The feeding mechanism 400 can accurately deliver the pipe fitting 200 to the specified position, and the displacement mechanism 500 and the jacking mechanism 600 can accurately adjust the position and height of the cover 100, providing good working conditions for the pressing mechanism 700. Through the accurate control of the third driving member 710, the pressing mechanism 700 can press the pipe fitting 200 into the cover 100 with appropriate pressure, avoiding problems such as damage to the pipe fitting 200 and insecure bonding caused by excessive or insufficient pressure, thereby ensuring the quality stability of the whole assembly process.

[0054] Since the whole assembly process is automated, the operator only needs to be responsible for the start, monitoring and simple maintenance of the equipment, without the need for complex manual operations such as gluing, handling of the pipe fitting 200 and pressing, greatly reducing the labor intensity. At the same time, the dependence on a large number of skilled workers is reduced, and the labor cost of the enterprise is reduced.

[0055] Reference Figures 3-8The support 620 comprises a first support base 621, a guide rod 622 and a first connecting base 623, the guide rod 622 and the first connecting base 623 are arranged on the first support base 621, and the guide rod 622 is movably connected with the sliding part 520; the output shaft of the second driving part 610 is connected with a second connecting base 611, one of the first connecting base 623 and the second connecting base 611 is provided with a clamping groove 623a, and the other is provided with a clamping block 611a, when the sliding part 520 is in the press-fitting station, the clamping block 611a is clamped in the clamping groove 623a. Wherein, the guide rod 622 is a rod-shaped structure for guiding the motion track of the sliding part 520, and axial sliding is realized by cooperating with the guide hole on the sliding part 520. The first connecting base 623 is a connecting component for transmitting lifting power, which can be fixed on the first support base 621 by bolts. The clamping groove 623a is a groove structure for accommodating the clamping block 611a, which can adopt a U-shaped groove or a T-shaped groove structure, and the opening direction thereof matches the motion track of the clamping block 611a. The clamping block 611a is a protruding structure which forms a plug-in fit with the clamping groove 623a, which can adopt a rectangular metal block and is fixed on the second connecting base 611 by welding or bolts.

[0056] Specifically, when the sliding part 520 moves to the press-fitting station, the second driving part 610 drives the second connecting base 611 to move in the vertical direction, so that the clamping block 611a forms a plug-in fit with the clamping groove 623a on the first connecting base 623. At this time, the guide rod 622 keeps sliding contact with the guide hole of the sliding part 520, ensuring that the support 620 does not deviate during lifting. The second driving part 610 transmits driving force through the clamping structure of the second connecting base 611 and the first connecting base 623, drives the first support base 621 and the cover 100 to perform precise lifting action, and provides stable support reference for subsequent press-fitting process.

[0057] The present application realizes the quick docking of the displacement mechanism 500 and the jacking mechanism 600 through the clamping structure, so that the support 620 can be displaced under the drive of the first driving part 510 to switch between the coating station and the press-fitting station, and can be lifted under the drive of the second driving part 610 to cooperate with the press-fitting mechanism 700 to realize the press-fitting of the cover 100 and the pipe 200, so that the movement of the support 620 in two directions is relatively independent, and the problem of press-fitting displacement of the pipe 200 caused by the deflection of the support 620 is inhibited.

[0058] In the embodiment of the present application, the clamping groove 623a is arranged on the first connecting seat 623, the clamping block 611a is arranged on the second connecting seat 611, the clamping groove 623a penetrates the first connecting seat 623 along the first direction X, and the lifting direction of the supporting piece 620 is the second direction Y; the clamping groove 623a and the clamping block 611a have a gap in the second direction Y and / or the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. The clamping groove 623a is a groove structure arranged on the first connecting seat 623, which can be realized by a rectangular groove or a dovetail groove, and is used to accommodate the insertion of the clamping block 611a. The clamping block 611a is a protruding structure arranged on the second connecting seat 611, which can be realized by a metal block matched with the shape of the clamping groove 623a, and is used to form a separable clamping relationship with the clamping groove 623a. The gap is the space reserved between the inner wall of the clamping groove 623a and the outer surface of the clamping block 611a, which allows the clamping block 611a to displace in the second direction Y or the third direction Z within the clamping groove 623a. The first direction X, the second direction Y and the third direction Z are perpendicular to each other, that is, the three spatial coordinate axes are orthogonal to each other, for example, the first direction X is a horizontal longitudinal direction, the second direction Y is a vertical direction, and the third direction Z is a horizontal transverse direction.

[0059] Specifically, when the sliding piece 520 moves to the press-fitting station, the clamping block 611a on the second connecting seat 611 is inserted into the clamping groove 623a of the first connecting seat 623. Since the clamping groove 623a penetrates the first connecting seat 623 along the first direction X, the clamping block 611a can freely enter or exit the clamping groove 623a in the first direction X. During the lifting process of the supporting piece 620, the second driving piece 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 clamping groove 623a and the clamping block 611a in the second direction Y or the third direction Z allows the supporting piece 620 to produce a slight offset during lifting, avoiding rigid collision at the clamping part due to machining errors or assembly deviations. And make the clamping block 611a can smoothly enter and exit the clamping groove 623a, can effectively compensate the assembly deviation of the first connecting seat 623 and the second connecting seat 611, avoid the wear or deformation of the clamping part caused by stress concentration.

[0060] The assembly device of the cover and the pipe fitting further comprises a rack 800, the rack 800 comprises a workbench 810 and a support frame 820, the workbench 810 is provided with a sliding rail 811 extending along the first direction X, the sliding piece 520 is provided with a sliding seat 521 and a first through hole 522, the sliding seat 521 is slidably connected to the sliding rail 811, and the first connecting seat 623 passes through the first through hole 522 and is connected with the second connecting seat 611. The rack 800 is the basic bearing structure of the whole device, which can be realized by welding a metal frame and a plate.

[0061] The workbench 810 is a horizontal bearing platform of the rack 800, the slide rail 811 is a guiding component extending along the first direction X, which can be implemented by a linear guide rail or a V-shaped groove structure, and is used for constraining the moving track of the sliding part 520. The sliding seat 521 is a sliding component matched with the slide rail 811, which is used for reducing the frictional resistance when the sliding part 520 moves. The first through hole 522 is a through hole provided on the sliding part 520, which can be implemented by a circular or rectangular hole structure, and is used for allowing 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 workbench 810 along the first direction X, and the sliding seat 521 is connected with the bottom of the sliding part 520 through bolts, so that the sliding part 520 can reciprocate along the slide rail 811 in the first direction X. The second connecting seat 611 is connected with the second driving part 610 through the first connecting seat 623 passing through the first through hole 522, so as to push the support part 620 to lift when the second driving part 610 is started. The cooperation of the slide rail 811 and the sliding seat 521 can ensure that the sliding part 520 remains stable when switching between the gluing station and the press-fitting station, and the arrangement of the first through hole 522 makes the power transmission path of the jacking mechanism 600 avoid the main body structure of the sliding part 520, so as to avoid motion interference.

[0063] The gluing mechanism 300 includes a fourth driving part 310, a mounting seat 320, a glue throwing device 330 and a glue injector 340. The fourth driving part 310 is arranged on the support frame 820, the mounting seat 320 is connected with the output shaft of the fourth driving part 310, the glue throwing device 330 and the glue injector 340 are both arranged on the mounting seat 320, and the glue injector 340 is used for injecting glue into the glue throwing disc 331 of the glue throwing device 330. When the sliding part 520 is in the gluing station, the fourth driving part 310 drives the mounting seat 320 to move downward, so that the glue throwing disc 331 of the glue throwing device 330 approaches the cover 100, and the glue throwing disc 331 of the glue throwing device 330 rotates to coat glue on the cover 100. The fourth driving part 310 is a power device capable of providing linear motion, which can be implemented by a pneumatic cylinder or an electric push rod, and is used for controlling the lifting action of the mounting seat 320. The glue throwing device 330 is a device with a rotating glue throwing disc 331, which can be implemented by a high-speed rotating disc structure driven by a motor, and the glue is uniformly thrown out by centrifugal force. The glue injector 340 is a device capable of quantitatively delivering glue, which can be implemented by a metering pump or a needle cylinder type glue injection device, and is used for injecting a predetermined amount of glue into the glue throwing disc 331. The mounting seat 320 is a bearing structure for fixing the glue throwing device 330 and the glue injector 340, which can be implemented by a metal plate or a frame structure.

[0064] Specifically, when the cover 100 is conveyed to the gluing station, the fourth driving member 310 pushes the mounting seat 320 to descend in the vertical direction, so that the glue throwing disc 331 of the glue throwing device 330 extends into the mounting hole 110 of the cover 100. The glue injector 340 quantitatively injects glue into the glue throwing disc 331, and the glue throwing disc 331 rotates at high speed under the driving of the motor, and the glue is uniformly coated on the hole wall of the mounting hole 110 of the cover 100 under the action of centrifugal force. The lifting action of the mounting seat 320 can avoid the collision between the glue throwing disc 331 and the cover 100.

[0065] The fourth driving member 310 is used to control the lifting of the mounting seat 320, so that the distance between the glue throwing disc 331 and the cover 100 can be flexibly adjusted to adapt to the gluing requirements of workpieces of various specifications. The automatic control of the glue coating process is realized, the uniformity of the glue film is significantly improved, and the unstable problem of the glue amount caused by manual operation is avoided.

The fifth driving member 350 is arranged on the support frame 820, and the collection box 360 is connected with the output shaft of the fifth driving member 350. The fifth driving member 350 is connected with the collection box 360 and drives the collection box 360 to move in the third direction Z, so that the collection box 360 can be located below the glue throwing disc 331 of the glue throwing device 330 after the glue throwing of the glue throwing device 330 is completed. The fifth driving member 350 is a device for providing linear or rotary power, which can be realized by using a cylinder or a servo motor. The output shaft of the fifth driving member 350 is connected with the collection box 360, so as to control the position movement of the collection box 360. After the glue throwing device 330 completes the glue coating, the fourth driving member 310 drives the glue throwing device 330 to move upward, and then the fifth driving member 350 is started to drive the collection box 360 to move in the third direction Z to be directly below the glue throwing disc 331. At this time, the residual glue or the dripping glue liquid splashed by the glue throwing disc 331 when rotating is received by the collection box 360, so as to avoid the pollution of the workbench 810 or the surface of the cover 100 by the glue. The position switching of the collection box 360 is synchronized with the glue throwing action, and the collection box 360 is moved to the predetermined position immediately after the gluing stage is completed, so as to ensure the timeliness of the glue recovery, reduce the frequency of manual intervention, and improve the cleanliness and overall assembly efficiency of the gluing process.

[0067] In the embodiment of the present application, the rack 800 further comprises a second support seat 830, which is arranged on the workbench 810 and located between the workbench 810 and the support frame 820. The second support seat 830 is provided with a second through hole 831 through which the pressing assembly 720 passes. The second driving member 610 drives the machine cover 100 on the support member 620 to abut against the second support seat 830, so that the machine cover 100 communicates with the second through hole 831. The feeding mechanism 400 comprises a vibrating disc 410, a material channel 420, a feeding member 430 and a sixth driving member 440. The material channel 420 is used for receiving the pipe member 200 conveyed by the vibrating disc 410 and conveying the pipe member 200 to the feeding member 430. The sixth driving member 440 is connected with the feeding member 430 and drives the feeding member 430 to move, so as to convey the pipe member 200 on the feeding member 430 into the second through hole 831.

[0068] The second support seat 830 is a supporting structure arranged between the workbench 810 and the support frame 820, which is used for providing support for the upper part of the machine cover 100 during the pressing process. The vibrating disc 410 is a feeding device with a directional sorting function. The automatic arrangement and conveying of the pipe member 200 can be realized by electromagnetic driving, which solves the problem of low efficiency of manual feeding. The material channel 420 is a transmission channel connecting the vibrating disc 410 and the feeding member 430. The curved slide rail 811 structure can be used to assist the pipe member 200 to slide to the feeding member 430 by gravity. The sixth driving member 440 is a power element for driving the feeding member 430 to perform linear motion, which can be a pneumatic cylinder or an electric push rod. The second through hole 831 is a guide channel penetrating through the second support seat 830, and the inner diameter of the second through hole 831 is slightly larger than the outer diameter of the pipe member 200, which is used for guiding the pipe member 200 to enter the mounting hole 110 of the machine cover 100.

[0069] Specifically, when the machine cover 100 is lifted by the jacking mechanism 600 to abut against the bottom of the second support seat 830, the second through hole 831 and the assembly hole of the machine cover 100 are coaxially aligned. After the vibrating disc 410 automatically sorts the disordered pipe members 200, the pipe members 200 are conveyed one by one into the feeding hole 431 of the feeding member 430 through the material channel 420. The sixth driving member 440 drives the feeding member 430 to move along the predetermined track, so that the pipe member 200 falls from the feeding hole 431 into the second through hole 831 and enters the mounting hole 110 of the machine cover 100 through the second through hole 831. In this process, the second support seat 830 not only provides a stable support plane for the machine cover 100, but also restricts the falling path of the pipe member 200 through the second through hole 831, so as to avoid the deviation of the pipe member 200 during the conveying process.

[0070] The application realizes the automatic connection of the pipe 200 conveying and pressing process by the automatic sequencing conveying of the vibration disc 410 and the material channel 420, in combination with the feeding member 430 driven by the sixth driving member 440, and eliminates the positioning errors caused by manual operation. The cooperation of the second support seat 830 and the feeding mechanism 400 enables the pipe 200 to accurately enter the mounting hole 110 of the machine cover 100, avoiding the pressing failure caused by the inclination or deviation of the pipe 200.

[0071] With reference to Figure 5 , Figure 8 , Figure 9 and Figure 10 , the feeding mechanism 400 further comprises a guide sleeve 450, one end of the guide sleeve 450 is inserted into the second through hole 831, the other end of the guide sleeve 450 is inserted into the machine cover 100, and the inner diameter of the guide sleeve 450 gradually decreases from the end away from the machine cover 100 to the end close to the machine cover 100. The guide sleeve 450 is a tubular structure with a tapered inner hole, which is used to guide the movement track of the pipe 200 during conveying, so that the pipe 200 can automatically adjust the position before entering the machine cover 100, and ensure the centering with the mounting hole 110 of the machine 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 machine cover 100. When the pipe 200 is pushed into the guide sleeve 450 by the feeding member 430, the pipe 200 first enters the end with a larger inner diameter, and gradually moves to the small-diameter end as the conveying process proceeds. Due to the continuous change of the inner diameter, the pipe 200 is radially constrained during movement, and its axis gradually coincides with the axis of the mounting hole 110 on the machine cover 100. In the pressing stage, the small-diameter end of the guide sleeve 450 tightly fits with the hole wall of the mounting hole 110 of the machine cover 100, forming a positioning reference, which ensures that the pipe 200 is pressed into the machine cover 100 along the predetermined path, and improves the pressing precision of the pipe 200 and the machine cover 100.

[0073] The jacking mechanism 600 further comprises a clamping assembly 630, which is arranged on the first support seat 621. The clamping assembly 630 comprises a plurality of clamping members 631, which are arranged at intervals in the circumferential direction of the machine cover 100. The clamping assembly 630 is a device for fixing the position of the machine cover 100, which can be realized by a pneumatic clamping jaw or a mechanical clamp, and the opening and closing actions of the clamping members 631 constrain the edge of the machine cover 100. The clamping member 631 is a component that directly contacts the machine cover 100 and applies a clamping force, which can be realized by a metal clamping block with a rubber contact surface to avoid scratching the surface of the machine cover 100. The plurality of clamping members 631 are arranged at intervals in the circumferential direction to form multi-point positioning, which suppresses the rotation deviation of the machine cover 100 during assembly.

[0074] Specifically, when the support 620 is lifted under the action of the second driving member 610, the plurality of clamping members 631 in the clamping assembly 630 act on the outer edge of the cover 100 synchronously. During the lifting process, the clamping members 631 remain in a closed state and offset the lateral displacement of the cover 100 through the circumferential distribution of clamping force. 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 deviating due to stress during the press-fitting process. After the press-fitting is completed, the clamping members 631 are released from the clamping state so as to take out the assembled cover 100.

[0075] In an embodiment, the second support seat 830 is provided with a plurality of elastic abutting members 840, which are arranged circumferentially around the second through hole 831. Each elastic abutting member 840 includes a mounting sleeve 841 and an abutting head 842 connected in an extendable manner. The mounting sleeve 841 is fixedly arranged on the second support seat 830, and the abutting head 842 is arranged to abut against the cover 100. The elastic abutting member 840 is a component that achieves a cushioned contact through an extendable structure, which can be implemented by a spring and sleeve structure. The abutting head 842 can adapt to the shape change of the cover 100 through the extension and retraction movement, and provide a cushion for the abutment between the cover 100 and the second support seat 830.

[0076] Specifically, when the second driving member 610 drives the cover 100 on the support 620 to rise and contact the second support seat 830, the outer edge of the cover 100 contacts the abutting head 842 of the plurality of elastic abutting members 840. Since the abutting head 842 and the mounting sleeve 841 are connected in an extendable manner, the abutting head 842 can adaptively extend and retract according to the shape of the cover 100 during the pressing process of the cover 100, so as to avoid local stress concentration caused by rigid contact. At the same time, the circumferentially distributed elastic abutting members 840 form an annular support region, so that the cover 100 can maintain a horizontal state during the press-fitting process, preventing deviation or deformation due to uneven stress.

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

[0078] The cap and pipe assembling device provided by the application integrates a plurality of functional mechanisms such as a gluing mechanism 300, a feeding mechanism 400, a displacement mechanism 500, a jacking mechanism 600, and a press-fitting mechanism 700, each mechanism automatically operates according to a preset program, without frequent manual intervention, realizes continuous automatic production of the cap 100 and the pipe 200 assembling, greatly shortens the assembling cycle, and improves the production efficiency. The first driving member 510 of the displacement mechanism 500 drives the sliding member 520 to accurately switch between the gluing station and the press-fitting station, ensures that the gluing and press-fitting operations are performed at the correct positions, and improves the positioning accuracy of the assembling. The guide sleeve 450 of the feeding mechanism 400 is inserted into the second through hole 831 at one end and is inserted into the cap 100 at the other end, and the inner diameter gradually decreases, which provides accurate guidance for the pipe 200 to enter the cap 100, avoids the deviation of the pipe 200 during the press-fitting process, and ensures the assembling accuracy of the pipe 200 and the cap 100. The elastic abutting member 840 on the second support seat 830 is circumferentially arranged around the second through hole 831. When the jacking mechanism 600 drives the cap 100 to abut against the second support seat 830, the elastic abutting member 840 can provide uniform elastic support force, so that the cap 100 remains stable during the press-fitting process, and the assembling quality of the cap 100 and the pipe 200 is further improved.
