DETAILED DESCRIPTION

[0027] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0028] Please refer to Figures 1 to 8 The utility model discloses a round pipe bottom cover assembling mechanism, which comprises a rack 1, a first bearing plate 11 arranged on the rack 1 and used for placing a round pipe, a positioning mechanism 2 for positioning the round pipe on the first bearing plate 11, a glue coating mechanism 3 for coating glue on the bottom of the round pipe positioned by the positioning mechanism 2, a carrying mechanism 4 for carrying the round pipe with a bottom cover into the round pipe coated with glue by the glue coating mechanism 3, and a pressing mechanism 5 for pressing and pasting the round pipe with the bottom cover.

[0029] In actual use, the positioning mechanism 2 is provided with two second bearing plates 21 matched with the first bearing plate 11, and two groups of rotating rubber wheel groups 22 are arranged on the second bearing plates 21. The rubber wheel groups 22 can abut against the outer wall of the circular pipe to accurately position the circular pipe, ensure the position accuracy of the circular pipe in subsequent processes such as glue coating, bottom cover mounting and pressing, and improve the assembly precision and quality. The driving motor 23 drives the two groups of rubber wheel groups 22 to rotate the circular pipe, and cooperates with the glue coating mechanism 3 to uniformly coat the bottom of the circular pipe. Uniform coating can ensure that the bottom cover and the circular pipe are more firmly and reliably pasted, avoid problems such as poor pasting and poor sealing caused by uneven coating, and improve the quality and performance of the product.

[0030] The assembly mechanism integrates multiple functional modules such as positioning, glue coating, carrying, bottom cover mounting and pressing, and the mechanisms work cooperatively to reduce manual operation links and improve the automation degree of production. This not only can improve the production efficiency, but also can reduce the labor cost and the influence of human factors on product quality, and ensure the stability of product quality. The rubber wheel groups 22 contact and position the outer wall of the circular pipe and drive the circular pipe to rotate. Compared with other positioning methods, the friction between the rubber wheels and the circular pipe is more uniform, and the rubber wheels themselves have a certain elasticity, which can adapt to circular pipes within a certain size range, making the circular pipe more stable during rotation, which is conducive to glue coating and subsequent processes. Since the design of the rubber wheel groups 22 can adapt to circular pipes with certain size changes, the assembly mechanism can be applied to the assembly of circular pipe bottom covers of various specifications, has good universality and flexibility, and can meet the production needs of different customers or different products.

[0031] Specifically, the carrying mechanism 4 has a first support plate 41 reciprocally arranged on the rack 1, a first driver 42 for driving the first support plate 41 to reciprocate, a second support plate 43 reciprocally arranged on the first support plate 41, a second driver 44 for driving the second support plate 43 to reciprocate, the moving direction of the first support plate 41 and the moving direction of the second support plate 43 are cross arranged, and an inclined positioning clamp 45 is installed on the second support plate 43. The inclined positioning clamp 45 is used for adsorbing the bottom cover and inclining the bottom cover, the center axis direction of the bottom cover is cross arranged with the moving direction of the second support plate 43, and the two drivers cooperatively drive the two support plates to reciprocate to incline the bottom cover adsorbed by the inclined positioning clamp 45 and put it into the circular pipe.

[0032] In actual use, the carrying mechanism 4 is provided with an inclined positioning clamp 45, which can adsorb the bottom cover and make it inclined, and the central axis direction of the bottom cover is crosswise arranged with the movement direction of the second supporting plate 43. This design can realize the inclined placement of the bottom cover into the circular pipe, meeting the specific assembly requirements. For example, in some cases, placing the bottom cover obliquely is more conducive to subsequent pressing and pasting, making the combination of the bottom cover and the circular pipe more tightly and stably, and improving the overall quality of the product. The first supporting plate 41 and the second supporting plate 43 are respectively driven by the first driver 42 and the second driver 44, and the reciprocating directions of the two are crosswise arranged. Through the cooperative driving of the two drivers and the two supporting plates, the inclined positioning clamp 45 can be accurately controlled, so that the adsorbed bottom cover can be accurately carried above the circular pipe and obliquely placed into the circular pipe. This ensures the position accuracy of the bottom cover in the assembly process, reduces the assembly errors or product quality problems caused by inaccurate placement.

[0033] The carrying mechanism 4 realizes the automatic carrying and placement of the bottom cover through the cooperation of the two drivers and the two supporting plates, reducing the manual intervention. This not only improves the production efficiency, but also reduces the errors and uncertainties caused by manual operation, making the entire circular pipe bottom cover assembly process more automated and intelligent, which is beneficial to improve the stability and consistency of production. The crosswise movement of the first supporting plate 41 and the second supporting plate 43, and the independent driving of the respective drivers, make the carrying mechanism 4 have high spatial movement flexibility. It can accurately move and position in different directions, can adapt to circular pipes of different specifications and positions, has better adaptability and universality for different production requirements, and expands the application range of the equipment.

[0034] Specifically, the inclined positioning clamp 45 has a carrying rod 46, one end of the carrying rod 46 is installed on the second supporting plate 43, the other end is provided with an inclined suction cup 47, the carrying rod 46 is provided with a pneumatic connector 48 for connecting an external vacuum generator, the pneumatic connector 48 is in communication with the inclined suction cup 47, and the central axis direction of the inclined suction cup 47 is crosswise arranged with the central axis direction of the carrying rod 46.

[0035] In actual use, the central axis direction of the inclined suction cup 47 is arranged transversely to the central axis direction of the carrying rod 46, and the pneumatic joint 48 is connected to the external vacuum generator. The bottom cover can be adsorbed by the generated vacuum adsorption force, and the adsorbed bottom cover can be in an inclined state due to the inclined design, thereby meeting the assembly requirement of placing the bottom cover into the circular pipe in an inclined manner, providing necessary conditions for accurate assembly of the bottom cover and the circular pipe, and ensuring the process requirement of product assembly. The external vacuum generator is connected through the pneumatic joint 48, and the vacuum adsorption principle is used. The inclined suction cup 47 can stably and firmly adsorb the bottom cover. Compared with other adsorption methods, the vacuum adsorption has high adsorption force and stability, and can ensure that the bottom cover does not fall or shift during the carrying process, thereby realizing accurate adsorption positioning of the bottom cover, laying a foundation for subsequent accurate placement of the bottom cover into the circular pipe, and improving the assembly precision and reliability.

[0036] Specifically, the glue applying mechanism 3 is located below the first bearing plate 11, and the first bearing plate 11 is provided with a glue applying through hole 12 for applying glue to the bottom of the circular pipe. The glue applying mechanism 3 has a glue applying gun 31 reciprocally arranged on the rack 1, and a glue applying driver 32 for driving the glue applying gun 31 to reciprocate. The direction in which the glue applying gun 31 sprays glue liquid is arranged transversely to the central axis direction of the circular pipe, and the glue applying driver 32 drives the glue applying gun 31 to pass through the glue applying through hole 12 to apply glue to the inner wall of the bottom of the rotating circular pipe.

[0037] In actual use, the glue applying mechanism 3 is located below the first bearing plate 11, and the direction in which the glue applying gun 31 sprays glue liquid is arranged transversely to the central axis direction of the circular pipe. At the same time, the glue applying gun 31 can pass through the glue applying through hole 12 to apply glue to the inner wall of the bottom of the rotating circular pipe. This unique design can accurately apply glue to the inner wall of the bottom of the circular pipe, meet the specific glue applying position requirement when the circular pipe is assembled with the bottom cover, ensure that the bottom cover is firmly pasted to the inner wall of the circular pipe, and improve the assembly quality and sealing performance of the product. The glue applying gun 31 reciprocally moves under the driving of the glue applying driver 32, and the glue liquid can be uniformly applied to the inner wall of the bottom of the circular pipe. Uniform glue application can avoid the situation that the glue liquid is accumulated or not applied in place, ensure the consistency of the pasting effect between the bottom cover and the circular pipe, and improve the overall quality of the product.

[0038] The gluing mechanism 3 drives the gluing gun 31 to reciprocate through the gluing driver 32, realizes the automatic gluing process, reduces the workload and human factors of manual gluing. The automatic gluing not only improves the gluing efficiency, but also ensures the relative stability of the position and the amount of glue each time, improves the consistency and reliability of production, and is beneficial to large-scale production. The reciprocating movement of the gluing gun 31 and the intersection with the center axis of the circular pipe enable it to adapt to the gluing needs of circular pipes of different specifications. For circular pipes of different diameters or lengths, only the movement parameters and position of the gluing gun 31 need to be adjusted appropriately, and effective gluing of the inner wall of the bottom of the circular pipe can be realized, improving the versatility and application range of the equipment and reducing the cost of replacing equipment for enterprises.

[0039] Specifically, the pressing mechanism 5 has a pressing support 51 arranged on the rack 1, and the pressing support 51 is provided with a reciprocating pressing plate 52, a pressing driver 55 for driving the pressing plate 52 to reciprocate, the pressing plate 52 is provided with a guide rod 53 in sliding fit with the pressing support 51, the center axis direction of the guide rod 53 is consistent with the reciprocating direction of the pressing plate 52, one end of the guide rod 53 is connected with the pressing plate 52, and the other end passes through the pressing support 51 and is provided with a pressing head 54 for pressing the bottom cover and the circular pipe, and the outer diameter of the pressing head 54 is smaller than the inner diameter of the circular pipe.

[0040] In actual use, the pressing mechanism 5 drives the pressing plate 52 to reciprocate through the pressing driver 55, and then drives the pressing head 54 to press the bottom cover and the circular pipe. Since the guide rod 53 in sliding fit with the pressing support 51 is arranged on the pressing plate 52, and the center axis direction of the guide rod 53 is consistent with the reciprocating direction of the pressing plate 52, this enables the pressing head 54 to accurately apply pressure to the bottom cover in a fixed direction during the pressing process, ensuring that the bottom cover and the circular pipe accurately fit in the vertical direction, improving the precision and quality of pressing, and ensuring that the connection between the two is firm and reliable. The guide rod 53 provides stable guiding for the reciprocating movement of the pressing plate 52. During the pressing process, the pressing plate 52 can move smoothly along the guide rod 53, reducing the possibility of shaking and deviation, so that the pressing head 54 can uniformly apply pressure to the bottom cover, avoiding problems such as bottom cover deformation or loose connection caused by uneven pressing. This stable movement characteristic helps to improve the pass rate of products and improve the overall assembly quality.

[0041] Specifically, the rubber wheel group 22 has two parallel arranged positioning rubber wheels 24, the output shaft of the driving motor 23 is provided with a first gear 25, the second bearing plate 21 is provided with two rotating second gears 26 and a tensioning wheel 27, the outer periphery of the first gear 25, the two second gears 26 and the tensioning wheel 27 is sleeved with a belt 28, the two second gears 26 and the two positioning rubber wheels 24 are coaxially arranged, and the four positioning rubber wheels 24 of the two rubber wheel groups 22 are in contact around the outside of the circular pipe.

[0042] In actual use, the rubber wheel set 22 adopts two positioning rubber wheels 24 arranged in parallel, and the circular pipe is positioned between the four positioning rubber wheels 24 of the two rubber wheel sets 22. This symmetrical positioning mode can uniformly apply pressure to the circular pipe, so that the circular pipe is stably fixed in the middle position, avoids deviation or shaking of the circular pipe during positioning and rotation, ensures the accuracy and stability of subsequent processes such as rubber coating, bottom cover installation and pressing, and improves the assembly quality of the product. The driving motor 23 transmits power to the positioning rubber wheel 24 through the first gear 25, the belt 28 and the second gear 26. The belt 28 transmission has the effects of buffering and vibration absorption, which can effectively reduce the impact and vibration in the power transmission process, so that the rotation of the positioning rubber wheel 24 is more stable. At the same time, the setting of the tensioning wheel 27 can maintain the tension of the belt 28, ensure the reliability of power transmission, avoid the phenomenon of belt 28 slipping, and ensure that the circular pipe can rotate stably at the predetermined speed and direction, which is beneficial to realize uniform rubber coating and other operations.

[0043] Due to the use of belt 28 transmission, the rubber wheel set 22 can adapt to circular pipes of different diameters to a certain extent. When the diameter of the circular pipe changes, by adjusting the tension of the belt 28 or replacing the belt 28 of different specifications, and appropriately adjusting the position of the positioning rubber wheel 24, the positioning and driving rotation of circular pipes of different diameters can be realized, which improves the versatility and application range of the equipment and meets the diversified production needs of enterprises.

[0044] Specifically, the two second bearing plates 21 are reciprocatingly arranged on the rack 1, and the rack 1 is provided with two positioning drives 29 for driving the two bearing plates to reciprocate, and the two positioning drives 29 cooperatively drive the two second bearing plates 21 to approach each other, so that the two rubber wheel sets 22 are in contact with the outer wall of the circular pipe located on the first bearing plate 11 to position the circular pipe.

[0045] In actual use, the two positioning drives 29 cooperatively drive the two second bearing plates 21 to approach each other, so that the two rubber wheel sets 22 can be in contact with the outer wall of the circular pipe located on the first bearing plate 11, thereby realizing accurate positioning of the circular pipe. This adjustable positioning mode can flexibly adjust the distance and pressure between the rubber wheel set 22 and the circular pipe according to the different diameters of the circular pipe, so that circular pipes of different specifications can be stably and accurately positioned, and the adaptability and versatility of the equipment to different products are improved. The positioning drive 29 is used to drive the second bearing plate 21, which realizes the automation of the positioning of the circular pipe. Manual adjustment of the position of the rubber wheel set 22 is not required for positioning the circular pipe, which reduces the manual operation link, improves the production efficiency, and also reduces the risk of inaccurate positioning caused by improper manual operation, thereby ensuring the stability and consistency of product quality.

[0046] When the two second bearing plates 21 are driven by the positioning drives 29 to approach each other, the two sets of rubber wheel groups 22 can closely adhere to the outer wall of the circular tube, providing stable support for the circular tube. This close adhesion and stable support helps the circular tube to maintain a fixed position during subsequent rotation, glue application, bottom cover installation, and pressing processes, avoiding the impact on product assembly quality caused by the shaking or displacement of the circular tube. The automated positioning process enables the circular tube to quickly enter the positioning state, saving time for subsequent glue application, transportation, pressing, and other processes, and improving the production efficiency of the entire circular tube bottom cover assembly process. At the same time, accurate positioning also reduces the rework or scrap rate caused by inaccurate positioning, further improving production efficiency and economic benefits. The two positioning drives 29 work cooperatively to make the movement of the two second bearing plates 21 more synchronized and stable, thereby ensuring that the positioning force of the two sets of rubber wheel groups 22 on the circular tube is evenly distributed. This stable positioning method helps to improve the stability of the entire equipment during operation, reduces equipment vibration and noise caused by unstable positioning, and prolongs the service life of the equipment.

[0047] Specifically, the circular tube bottom cover assembly mechanism further comprises a power source system for driving the intermittent movement of the first bearing plate 11, and the number of rubber wheel groups 22 is set to multiple, and the multiple rubber wheel groups 22 are arranged on the second bearing plate 21 along the moving direction of the first bearing plate.

[0048] In actual use, through intermittent motion control, the circular tube bottom cover can be accurately stopped at each station during assembly, ensuring the synchronization of processing or assembly actions and improving process connection efficiency. At the same time, mechanical vibration is reduced, and positioning error is reduced. The linear distribution of multiple rubber wheel groups 22 on the second bearing plate 21 forms a continuous guide and support surface, evenly disperses the load of the circular tube bottom cover, and avoids local stress concentration. This design can adapt to the transmission needs of bottom covers of different sizes, enhancing the compatibility of the mechanism. The first bearing plate 11 is responsible for intermittent conveying, and the second bearing plate 21 provides stable support with rubber wheel groups. The division of labor is clear. This layout optimizes the power transmission path, reduces the risk of motion component interference, and prolongs the service life of the equipment. The elastic material of the rubber wheel group 22 can buffer the impact during intermittent start and stop, prevent the displacement or overturning of the bottom cover, and is especially suitable for maintaining running stability at high production rhythm, reducing the rate of defective products.

[0049] Specifically, the rack 1 is also provided with a visual detection mechanism 6, which has a detection bracket 61, a camera unit 62, and a ring-shaped light source 63 cooperating with the camera unit 62. The camera unit 62 takes pictures of the circular tube and transmits the captured images to the control system of the circular tube bottom cover assembly mechanism. The control system analyzes the image information transmitted by the camera unit 62 and controls the coordinated operation between the mechanisms.

[0050] In actual use, the detection support 61 is fixed on the rack 1 to provide a rigid mounting reference for the camera unit 62 and the annular light source 63, ensuring the positional stability of the optical assembly during detection and avoiding imaging errors caused by vibration or deviation. The camera unit 62 captures high-resolution images of the bottom cover positioning, assembly gap, and sealing surface state in real time through multi-dimensional shooting at vertical or inclined angles, realizing non-contact detection, replacing traditional manual visual inspection, and improving detection efficiency and accuracy. The annular light source 63 is coaxially arranged around the camera unit 62, which can eliminate the interference of the curved surface reflection of the circular tube, uniformly illuminate the detection area, and enhance the image edge contrast, especially suitable for identifying scratches on the metal bottom cover surface or the uniformity of the adhesive layer. After the image data is transmitted to the control system in real time, the algorithm analyzes the parameters such as the position of the circular tube and the assembly deviation of the bottom cover, and automatically adjusts the docking position of the first bearing plate 11 or the pressing force of the rubber wheel set 22, forming a "detection- correction-execution" closed loop to reduce the assembly defect rate. The visual detection results are linked with the power source system and the rubber wheel set, etc. execution mechanism, for example, when the bottom cover is detected to be tilted, the mechanism is triggered to pause and reset, avoiding continuous scrap caused by single-point failure, and ensuring the stability of the overall beat of the production line.

[0051] Specifically, the rack 1 is also provided with a feeding mechanism 7, which has a rotating feeding conveying line 71, a feeding drive 72 for driving the feeding conveying line 71 to rotate, the feeding conveying line 71 is provided with a feeding bin 73 for feeding the bottom covers one by one, and a V-shaped stop edge 74 for cooperating with the carrying mechanism 4, the feeding bin 73 has a bin support 731 reciprocally arranged on the feeding conveying line 71, a bin drive 732 for driving the bin support 731 to reciprocate, and the movement direction of the bin support 731 is crosswise arranged with the transportation direction of the feeding conveying line 71; the bin support 731 is provided with two limiting plates 733 limiting the two ends of the circular tube along the vertical direction of the feeding conveying line 71, and a pressing head 734 for pressing a plurality of bottom covers on the feeding conveying line 71, and a gap is provided between the bin support 731 and the feeding conveying line 71 for a single bottom cover to pass through, a plurality of bottom covers are limited on the feeding conveying line 71 by the limiting plates 733 and the pressing head 734, the feeding conveying line 71 transports the bottom cover at the lowermost end of the feeding bin 73 to the V-shaped stop edge 74 one by one, and the V-shaped stop edge 74 positions the bottom cover on the feeding conveying line 71 to cooperate with the carrying mechanism 4 to carry the bottom cover above the circular tube.

[0052] In actual use, the feeding conveying line 71 is continuously rotated by the feeding driver 72, and cooperates with the reciprocating movement of the hopper support 731 (driven by the hopper driver 732) to form the beat control of "dynamic feeding-static sorting". The movement direction of the hopper support 731 is crosswise arranged with the conveying direction of the conveying line, which not only avoids movement interference, but also can be flexibly adapted to the feeding frequency of bottom covers of different sizes by adjusting the stroke. The limiting plate 733 limits the two ends of the bottom cover along the direction perpendicular to the conveying direction, and the pressure head 734 applies vertical pressure to the stacked bottom cover, so as to ensure that the bottom cover is aligned during conveying. The gap between the hopper support 731 and the conveying line is designed to allow only a single bottom cover to pass, and the balance between gravity and friction is used to realize single feeding, which effectively prevents multiple feeding or jamming.

[0053] The V-shaped stop edge 74 at the end of the conveying line forms a bevel contact with the edge of the bottom cover, which automatically corrects the planar position and angular deviation of the bottom cover before being grabbed by the carrying mechanism 4, so as to ensure that the bottom cover is accurately guided to a position coaxial with the circular pipe, thereby reducing the risk of assembly misplacement. The horizontal limiting (restricting X / Y direction displacement) of the limiting plate 733 and the vertical pressure holding (restricting Z direction jumping) of the pressure head 734 form three-dimensional limiting, which can maintain the stability of the bottom cover stack even when the conveying line is running at high speed. When the pressure head 734 is made of elastic material, it can adapt to the thickness fluctuation of the bottom cover and reduce mechanical damage. After the feeding conveying line 71 conveys the bottom cover at the bottom end to the V-shaped stop edge 74, the carrying mechanism 4 (such as a mechanical hand) can accurately grab based on visual or sensor signals. This design realizes the beat synchronization of feeding-positioning-carrying by matching the conveying line speed and the reciprocating period of the hopper support 731, thereby improving the overall assembly efficiency. The modular design of the feeding hopper 73 allows quick replacement of the spacing of the limiting plate 733 or the pressure parameters of the pressure head 734, which is suitable for bottom covers of different diameters / thicknesses. The separated structure of the conveying line and the hopper support 731 facilitates separate maintenance and reduces downtime.

[0054] In this embodiment, the inclined suction cup 47 is detachably connected with the carrying rod 46.

[0055] In actual use, through the detachable structure, different inclination and material of the suction cup can be replaced according to the size or surface curvature of the bottom cover, for example, a flexible inclined suction cup 47 is used for the arc-shaped bottom cover, and a rigid suction cup is used for the flat bottom cover. This design avoids replacing the overall carrying mechanism 4, significantly improving the versatility of the equipment. As a consumable, the suction cup can be independently detached, cleaned or replaced without disassembling the main body structure of the carrying rod 46. Using magnetic fast disassembly or buckle locking mechanism, the single operation time can be shortened to 30 seconds, reducing the production line downtime loss caused by the wear of the suction cup. The installation angle of the inclined suction cup 47 can be finely adjusted (such as ± 15°), so that it is aligned with the normal direction of the bottom cover curved surface, ensuring the vertical action of the negative pressure adsorption force, preventing slipping or falling during carrying due to angle deviation, especially suitable for grabbing high smoothness metal bottom cover. The detachable connection can be integrated with a buffer gasket or damping mechanism to absorb the inertial impact when the carrying rod 46 moves at high speed, reduce the vibration transmitted to the suction cup, and avoid scratches on the surface of the precision bottom cover caused by mechanical vibration.
