DETAILED DESCRIPTION

[0030] Combine the following Figure 1-Figure 11 The present invention is described in detail.

[0031] Embodiment 1:

[0032] The water meter assembly line with a loading and positioning function of the present invention comprises a ring cover positioning module 2, a loading module 4, a transfer module 6, a press-fitting module 8, a meter body positioning module 9, a storage module 1 and a ring cover positioning and loading module 3.

[0033] like Figure 2 The material storage module 1 is used for storing materials. The material storage module 1 can adopt a box body. The material storage module 1 is provided with a ring cover support 11 for stably placing the ring cover 5. The ring cover support 11 can be formed of plastic so that the ring cover 5 can be stably placed in the material storage module 1, and the placed ring covers 5 are arranged horizontally and vertically.

[0034] like Figure 4The ring cover positioning and loading module 3 includes a material picking displacement drive component and a material picking mechanism 34. The material picking mechanism 34 is used to grab the material in the storage module 1. The grabbing method is a clamping claw or a negative pressure suction method. The material picking displacement drive component is used to drive the material picking mechanism 34 to transfer the material. The material picking displacement drive component includes an X-axis translation mechanism 31, a Y-axis translation mechanism 32 and a Z-axis translation mechanism 33. The material picking mechanism 34 includes a material picking rotating body 341 and a material picking arm 342. The material picking arm 342 is connected to the material picking rotating body 341. Two mutually perpendicular material picking claws 343 are arranged on the material picking arm 342, which can grab two ring covers 5 to improve the loading efficiency.

[0035] The material picking rotating body 341 can be driven by a motor or pneumatically. When grabbing, the lower side material picking claw 343 is first used to descend and grab. After moving, the other side material picking claw 343 rotates to grab. The grabbing process of the other side material picking claw 343 can be carried out synchronously when moving toward the ring cover positioning module 2, thereby improving efficiency.

[0036] like Figure 3 Two groups of ring cover positioning modules 2 are set to receive the two materials transferred by the ring cover positioning and feeding modules 3 to further improve efficiency. The ring cover feeding and positioning system also includes a feeding module 4. The feeding module 4 is used to grab the positioned ring cover and transfer it. The feeding module 4 is preferably a manipulator, which can be set in one group or two groups. When two groups are set, they are used for loading the surface body and the ring cover respectively. The feeding module 4 grabs the ring cover 5 that has been positioned in the ring cover positioning module 2 and transfers it to the subsequent workstation.

[0037] The ring cover positioning module 2 comprises a rotation positioning mechanism 21 and an in-position detection mechanism 22 .

[0038] The rotation positioning mechanism 21 includes a turntable 211, a clamping mechanism 212 and a driving mechanism 213. The driving mechanism 213 includes a rotation drive for driving the turntable 211 and a clamping drive for driving the clamping mechanism 212 to move the clamping jaws. The rotation drive can be driven by a motor, and the clamping jaw drive can be driven by a motor or a pneumatic drive. The clamping mechanism 212 is installed on the turntable 211. The clamping mechanism 212 is used to clamp the material. The clamping mechanism 212 is configured as an outward-expanding three-claw structure. The outside of the three clamping claws are provided with a flat plate structure for placing the ring cover 5. The clamping claws are in contact with the inner wall of the ring cover to achieve centering and fixation.

[0039] The in-place detection mechanism 22 includes a detection component 223 , and the detection component 223 is mounted on a detection bracket 221 .

[0040] The detection component 223 includes a sensor component 2234, which can detect whether the ring cover 5 is rotated to a set angle. The sensor component 2234 can be selected as one or more of an infrared sensor, a photoelectric sensor, and an ultrasonic sensor, or an image sensor can also be used. The sensor component 2234 identifies the positioning groove 51 of the ring cover 5 to determine whether the ring cover 5 is adjusted to a set angle. After the ring cover 5 is adjusted to the set angle, the sensor component sends an in-position instruction to the control module, and the control module sends a stop rotation instruction to the turntable 211.

[0041] The transfer module 6 includes a transfer body and a tool 62, such as Figure 8 The transfer body is a circular turntable 61, which is connected to a transfer driving mechanism 64. A plurality of tooling 62 are evenly arranged on the turntable 61. In this embodiment, five groups of tooling 62 are provided to realize multi-station synchronous operation and achieve high-efficiency production effects.

[0042] like Fig.10 , Fig.11 The tooling 62 includes a watch body clamping body 621 and a clamping drive. The watch body clamping body 621 is provided with at least two groups, which are respectively used to clamp the two sides of the watch body 10. The clamping drive includes a driving rod 622, a sliding body 623, a bottom plate 624 and a watch body support plate 625. The bottom plate 624 is connected to the turntable 61. The sliding bodies 623 and the watch body clamping bodies 621 are provided with the same number and are connected to each other. The sliding bodies 623 are slidably installed on the bottom plate 624. The driving rod 622 and the sliding bodies 623 are connected by transmission. The distance between the sliding bodies 623 is adjusted by the action of the driving rod 622.

[0043] Optionally, a transmission structure such as a crank rocker structure, an inclined plane transmission mechanism, etc. can be used between the driving rod 622 and the sliding body 623 to control the movement of the sliding body 623 through the left and right movement of the driving rod 622 .

[0044] In this embodiment, Fig.11 The sliding body 623 is provided with an inclined hole structure, and the driving rod 622 is provided with a transmission pin. When the driving rod 622 moves, the transmission pin transmits the inclined hole structure to make the sliding bodies 623 approach or move away from each other.

[0045] The watch body support plate 625 is disposed on the upper side of the sliding body 623 for supporting components. The contour of the watch body clamping body 621 preferably matches the contour of the watch body 10 to facilitate achieving a better clamping effect.

[0046] like Fig.10The watch body positioning module 9 includes a clamping positioning drive mechanism 92, which is the power of the driving rod 622. The clamping positioning drive mechanism 92 is separately arranged from the driving rod 622. After the watch body 10 is clamped by the watch body clamping body 621, the fixing effect of the watch body 10 is guaranteed in the subsequent transfer process. At the same time, since the clamping positioning drive mechanism 92 and the tooling 62 are separately arranged, there is no need to set a clamping drive on each tooling 62, which saves costs and reduces the control difficulty. When the subsequent press-fitting is completed and reaches the unloading station, a clamping positioning drive mechanism 92 can also be set at the unloading station to control the release of the watch body 10.

[0047] The clamping and positioning drive mechanism 92 can adopt a cylinder, and the piston rod of the cylinder completes the clamping action by pushing or pulling the drive rod 622. When pulling is used to achieve clamping, an electromagnet or a suction cup needs to be set at the end of the piston rod to achieve connection with the drive rod 622.

[0048] The watch body positioning module 9 includes an initial positioning mechanism 91, which is used to initially return the watch body 10 to a correct position or to make it approach or reach a correct position, thereby avoiding a large scratch problem during the subsequent clamping process.

[0049] like Fig.10 The initial positioning mechanism 91 includes a rotating body 914 and an initial positioning clamping plate 915 connected to the rotating body 914. At least two groups of rotating bodies 914 are arranged and installed on a rotating base. Two groups of corresponding initial positioning clamping plates 915 are also arranged. The two groups of rotating bodies 914 adjust the separation and clamping state switching of the two groups of initial positioning clamping plates 915 by rotation. When the initial positioning clamping plates 915 are in the separated state, they are not on the transfer route of the tooling 62 and do not affect the movement of the tooling 62.

[0050] Specifically, the initial positioning mechanism 91 also includes a rack drive assembly 912 and a rack 913. The rack drive assembly 912 can use a cylinder. The rack drive assembly 912 is used to drive the rack 913 to move up and down. A gear 916 meshing with the rack 913 is provided on the rotating body 914. The rotation of the rotating body 914 is controlled by the action of the rack 913. When not clamped, the rotating body 914 is in an unfolded state, and the tooling 62 can be transferred to this workstation.

[0051] The initial positioning mechanism 91 further includes a supporting connecting body 911 , which is connected to the mounting support 81 , and a rack driving assembly 912 and a rotating base in the initial positioning mechanism 91 are mounted on the supporting connecting body 911 .

[0052] When positioning the parts, the parts are first clamped by the initial positioning clamp 915 to make the initial adjustment of the position of the parts in the tooling 62, and then the parts are clamped by the watch body clamping body 621. The parts and accessories are transferred to the press-fitting module 8 by the transfer body and press-fitted by the press-fitting module 8.

[0053] like Figure 8 The press-fitting module 8 includes a press-fitting driving mechanism 82 and a press-fitting body 83 , both of which are mounted on the mounting support portion 81 . The press-fitting driving mechanism 82 can be a cylinder or a hydraulic cylinder, and the surface contour of the press-fitting body 83 matches the contour of the ring cover 5 .

[0054] The press-fitting module 8 also includes a bottom support mechanism 84 , which is correspondingly arranged to the press-fitting body 83 and respectively arranged on the upper and lower sides of the turntable 61 . The bottom support mechanism 84 is used to support the bottom of the turntable 61 to prevent structural deformation caused by downward pressure.

[0055] The unloading module 7 can adopt a manipulator, a clamping mechanism, etc., and can grab the product in the tooling and place the product on the unloading conveyor line or the unloading station or the subsequent station.

[0056] The water meter press-fitting method comprises the following steps:

[0057] Loading step: using the loading module 4 to place the meter body 10 between the meter body clamping bodies 621 of the tooling 62, and using the transfer body to transfer the tooling 62 to the meter body positioning station;

[0058] The step of positioning the watch body: driving the rotating body 914 to rotate, so that the initial positioning clamping plate 915 clamps the end position of the watch body 10, so that the watch body 10 is as close to the correct position as possible in the tooling 62, and the watch body clamping body 621 is used to clamp the watch body 10 to complete the positioning of the watch body 10, and ensure that the position of the watch body 10 in the tooling 62 is fixed during the subsequent transfer process;

[0059] Press-fitting step: the loading module 4 places the ring cover 5 on the meter body 10, uses the transfer body to transfer the tooling 62 to the press-fitting station, and uses the press-fitting module 8 to perform press-fitting;

[0060] Unloading step: Use the transfer body to transfer the tooling 62 to the unloading station, and use the unloading module 7 to grab the product to complete the unloading.

[0061] Embodiment 2:

[0062] On the basis of Example 1, in this embodiment, the in-place detection mechanism 22 also includes a detection lifting drive 224. The detection lifting drive 224 and the detection component 223 are both installed on the detection bracket 221. The detection lifting drive 224 is connected to the detection component 223 through the support arm 222. The detection lifting drive 224 can use a pneumatic cylinder or an electric cylinder.

[0063] The detection component 223 also includes a negative pressure component 2232. The detection component 223 is connected to a detection lifting drive 224. The detection lifting drive 224 is used to drive the detection component 223 to move up and down.

[0064] Since the ring cover 5 is placed at a random angle on the clamping mechanism 212, its positioning groove 51 is blocked by the clamping claw. At this time, the detection lifting drive 224 drives the negative pressure component 2232 to contact the bottom surface of the ring cover 5, and generates negative pressure to absorb the ring cover 5, so that the clamping mechanism 212 can rotate alone, and the clamping claw of the clamping mechanism 212 shrinks. The platform of the shrunken clamping claw still supports the ring cover 5, and the turntable 211 rotates a certain angle, generally 10-20°, so that the positioning groove 51 and the clamping claw can be staggered, which is convenient for subsequent re-positioning.

[0065] Optionally, the detection component 223 further includes a blowing component 2233. There may be impurities in the positioning groove 51 of the ring cover 5, such as foam particles during transportation, which affect the positioning. The blowing component 2233 can blow away the impurities.

[0066] Optionally, the negative pressure suction of the negative pressure component 2232 can also be used for cleaning.

[0067] The negative pressure component 2232 and the sensor component 2234 can be separately provided or can be provided on the same structure.

[0068] The negative pressure assembly 2232 is not limited to being provided in one group.

[0069] The ring cover feeding and positioning method comprises the following steps:

[0070] Material picking steps: Use the material picking displacement drive component to drive the material picking mechanism 34 to grab the material in the storage module 1, and transfer the material to the clamping mechanism 212 of the ring cover positioning module 2. When grabbing, first use the lower side material picking claw 343 to descend and grab. After moving, the other side material picking claw 343 rotates to grab. The grabbing process of the other side material picking claw 343 can be carried out synchronously while moving in the direction of the ring cover positioning module 2 to improve efficiency.

[0071] Positioning steps: Use the turntable 211 to drive the clamping mechanism 212 to rotate, so that the material rotates, and use the sensor component 2234 to detect whether the material has reached the set angle. When the material rotates to the set angle, the sensor component 2234 sends an in-position command, and the turntable 211 stops rotating; when the material is still not positioned after rotating one circle, use the detection lifting drive 224 to make the negative pressure component 2232 contact with the material. After the clamping mechanism 212 rotates the set angle alone, the negative pressure component 2232 separates from the material, and the turntable 211 drives the material to rotate for repositioning.

[0072] Loading step: The positioned ring cover is grabbed by the loading module 4 and transferred to the subsequent assembly station.

[0073] The loading module 4 generally adopts a robot arm to grab the ring cover 5 and the table body 10 for loading.

[0074] Embodiment 3:

[0075] On the basis of Example 2, Figure 6 , the detection component 223 also includes a column 2231, Figure 6 It is a schematic diagram of the top surface structure of the column 2231, the negative pressure component 2232, the blowing component 2233 and the sensor component 2234 are all installed on the column 2231, and an image sensor is preferably arranged, wherein the negative pressure component 2232 includes a plurality of suction cup structures arranged in the outer circle, the blowing component 2233 and the sensor component 2234 are arranged in the middle position, and the column 2231 has a non-smooth surface. When there are burrs or impurities that are difficult to blow away in the positioning groove 51, the detection lifting drive 224 drives the column 2231 to extend into the positioning groove 51 to scrape off the impurities, burrs and other structures on its surface.

[0076] Embodiment 4:

[0077] Based on any of the above embodiments, the bottom support mechanism 84 includes a support roller 841 and a movable support assembly 842. The movable support assembly 842 uses a spring or a pneumatic cylinder to ensure that the support roller 841 has a certain degree of floating distance.

[0078] The bottom plate 624 is connected to the contact body 63, and the contact body 63 is installed in the installation hole on the turntable 61. The bottom of the contact body 63 protrudes from the bottom surface of the turntable 61, and the support roller 841 rolls in contact with the bottom of the turntable 61. When in contact with the bottom surface of the contact body 63, the support roller 841 drops to a certain height, and the dropped height is slightly smaller than the height of the bottom of the contact body 63 protruding from the bottom surface of the turntable 61, so that the bottom support mechanism 84 can withstand most of the downward pressure and reduce the force on the turntable 61. In order to keep the tooling 62 stable when the bottom support mechanism 84 supports the contact body 63, a floating support or an elastic support may be provided on the upper end surface of the turntable 61.

[0079] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
