[0002] The accumulation and release chain production line for power capacitors is an automated intelligent production line that integrates capacitor cleaning, storage, testing, shot blasting, spraying, and drying. When spraying paint on the outer surface of the product, it is necessary to spray one side of the capacitor product, then rotate it 180°, and the robot will automatically spray paint on the other side. However, sometimes the product may not rotate into place, or even only rotate 90°, that is, when spraying the product, it is very easy to cause the spray gun on the robot to be damaged. Spare parts for spray gun repairs are expensive, and the downtime for maintenance is long, which seriously affects production output. In the existing technology, the gear is engaged by the cylinder to suspend the trolley gear in place, and the spring force controls the clamping force, which is prone to tooth jumping, resulting in misrotation; in addition, the backstop at the rear end of the trolley is not effective, which can also cause tooth jumping, resulting in misrotation.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. As used herein, "one" not only means "only one" but also "more than one."

[0052] The following is a detailed description of a rotation positioning device for a suspension trolley proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0053] Example

[0054] 1 to 7 , this embodiment provides a rotation positioning device for a suspension trolley, the main body of which includes: a link track, a suspension trolley, a stop assembly, and a rotation positioning assembly.

[0055] As shown in Figures 1 and 2, the link track is the transmission device of this embodiment. It includes an accumulation track located above and a travel track located below. The accumulation track and the travel track are arranged in a completely corresponding manner. The stop assembly is located on the accumulation track, the suspension trolley travels on the travel track, and the rotation positioning assembly is located on both sides of the entire link track.

[0056] Referring to Figures 1 and 2, the suspension trolley specifically includes a crossbeam, a trolley rotating rod, a passive gear, a first traveling trolley, a second traveling trolley, a first connecting member, a second connecting member, and a supporting member. A detailed description will now be provided based on the accompanying drawings, beginning with the crossbeam of the suspension trolley. The interior of the crossbeam is a hollow structure, with its two ends connected to one end of the first connecting member and one end of the second connecting member, respectively. The other end of the first connecting member extends upward through the crossbeam to connect to the first traveling trolley, while the other end of the second connecting member extends upward through the crossbeam to connect to the second traveling trolley. The first and second traveling trolleys can then travel within the traveling track. The trolley rotating rod serves as the central axis of the crossbeam and is rotationally connected to the crossbeam. The upward end of the trolley rotating rod extends above the crossbeam and is fitted with a passive gear secured with a nut. Rotation of the passive gear drives the trolley rotating rod to rotate synchronously. The other end of the trolley rotating rod extends below the crossbeam and is fixedly connected to the supporting member, which is used to carry the capacitor to be sprayed.

[0057] Referring to Figures 1 to 3, in this embodiment, a rotary positioning assembly is located on either side of the link track, cooperating with the passive gear of the suspension trolley to position and rotate the suspension trolley. Specifically, the rotary positioning assembly comprises a rotating assembly and a positioning assembly, each located on either side of the link track. The positioning assembly first positions the passive gear, and then the rotating assembly drives the passive gear, thereby driving the capacitor to rotate around the trolley's rotating rod.

[0058] The rotating assembly is now explained. It is divided into a rotating drive assembly, a rotating push assembly, and a rotating slide assembly, according to their respective functions. These three components work together to rotate the passive gear. The rotating drive assembly is connected to the rotating slide assembly. The rotating push assembly is located to one side of the rotating drive assembly, away from the link track. The rotating push assembly is connected to the rotating slide assembly. The rotating push assembly pushes the rotating slide assembly, sliding the rotating drive assembly to the hanging trolley, thereby rotating the passive gear.

[0059] The rotary slide assembly consists of a first slider, a first guide rail, and a first base plate. The first guide rail is actually composed of two parallel rails. The two first sliders are slidably connected to the top of the first guide rails, and the first base plate is connected above the two first sliders. The first base plate can move forward or backward under the action of the rotary push assembly. Forward moves it closer to the accumulation track, and backward moves it away from the accumulation track.

[0060] The rotary drive assembly includes a drive motor and a drive gear. The drive motor is fixed to the upper end surface of the first base plate. The drive motor is actually a combined drive mechanism with a motor and a gearbox in one. The drive output end of the drive motor is provided with a drive gear. As can be seen from the figure, the output shaft of the drive motor is provided with the drive gear after passing through the first base plate. The drive gear and the passive gear need to be located on the same horizontal plane so that the drive gear and the passive gear can be successfully engaged and the passive gear can be driven by the drive motor to rotate. The connection setting of the drive gear is supported by a coupling connecting the spindle, bearings and bearing seats. The drive gear is locked by a round nut and a basket washer, and a key pin is provided to prevent the gear from sliding on the shaft.

[0061] The rotary pushing assembly includes a first linear cylinder, a first cylinder connecting plate and a cylinder rod floating connecting piece. The output end of the first linear cylinder is set toward the link track. The cylinder rod floating connecting piece connects the cylinder rod of the first linear cylinder to one end of the first cylinder connecting plate. The other end of the first cylinder connecting plate is fixedly connected to the upper end surface of the first base plate. The first linear cylinder pushes the first base plate forward, so that the driving gear is pressed into the passive gear to realize gear meshing.

[0062] Next, referring to Figures 1, 2, and 7, the positioning assembly is described. The positioning assembly can be separated into a positioning gear assembly, a positioning pusher assembly, and a positioning rail assembly according to their functions. The positioning gear assembly is connected to the positioning rail assembly, which in turn is connected to the positioning rail assembly. The positioning pusher assembly pushes the positioning rail assembly, thereby sliding the positioning gear assembly to the suspension trolley to position the passive gear.

[0063] Similar in design to the rotating slide assembly, the positioning slide assembly includes a second slider, a second guide rail, and a second base plate. The second guide rail consists of two parallel rails, with two second sliders slidingly connected to the top of each second guide rail. The second base plate is connected above the two second sliders. The positioning push assembly allows the second base plate to move forward or backward.

[0064] The positioning pushing assembly includes a second linear cylinder, a second cylinder connecting plate and a cylinder rod floating connecting piece. The output end of the second linear cylinder faces the link track. The cylinder rod floating connecting piece is respectively connected to the output shaft of the second cylinder and one end of the second cylinder connecting plate. The other end of the second cylinder connecting plate is fixedly connected to the upper end surface of the second base plate. The second linear cylinder pushes the second base plate forward, so that the positioning gear is pressed into the passive gear to achieve V-shaped positioning.

[0065] The positioning gear assembly is fixed to the lower end surface of the second base plate and consists of two small gears, two spindles, key pins, gears, gear fixing plates, etc. The positioning gears are locked by round nuts and basket washers. The two positioning gears and the passive gear are located on the same horizontal plane and are driven by the positioning push assembly to achieve V-shaped positioning with the passive gear.

[0066] Preferably, in order to achieve control of the rotation angle, taking Figure 2 as an example, an elastic positioning assembly is also provided inside the crossbeam of this embodiment. The elastic positioning assembly includes a fixed rod, a detection rod, an elastic member (spring), and a detection unit. The fixed rod is arranged vertically, with its ends bolted to the upper and lower end faces of the crossbeam. The detection rod extends through the fixed rod and is arranged toward the trolley rotating rod. An elastic member is provided at one end of the detection rod near the trolley rotating rod, and a detection unit is provided at the other end of the elastic member, which is arranged against the trolley rotating rod. The connection between the trolley rotating rod and the detection unit is a square journal. During the rotation of the trolley rotating rod, the position of the detection unit will change, causing the length of the spring to change, and thus the elastic pressure of the spring to continuously change. Due to the square journal structure design of the trolley rotating rod, the elastic pressure is the same when the trolley rotating rod rotates 90°, 180°, 270°, and 360°, thereby achieving rotational positioning. Of course, in this embodiment, only 180° rotation positioning is required during spraying. After the trolley rotating rod rotates 180°, the relevant electrical control drive mechanism is used to disengage the rotating assembly and the positioning assembly from the passive gear. After the subsequent spraying is completed, the suspension trolley is restarted and sent to the next process.

[0067] 2 , the stop assembly is provided on the link track and is located in the capacitor spraying area, and is used to stop the introduced suspension trolley in the spraying area.

[0068] Specifically, referring to Figure 4, in this embodiment, the stop assembly includes a stopper, which is located on one side of the travel track. The stopper comprises a cylinder, a cylinder joint, a stopper connecting plate, a stopper plate, and a stopper frame. The stopper connecting plate is welded to one side of the travel track, and the stopper frame is secured to the stopper connecting plate with four screws. The stopper frame is connected to the cylinder via the cylinder joint. The stopper plate is driven by the cylinder to retract and extend. When extended, it blocks the trolley; when retracted, it allows the trolley to pass normally.

[0069] Specifically, referring to Figure 5, the stop assembly includes a backstop, which is installed on one side of the running track and is used to prevent the suspended trolley from moving backward. It is mainly composed of a backstop connecting plate, a rotating shaft, a buffer pad, a bracket, a backstop plate, a counterweight block, and a backstop connecting piece. When the front end of the front wheel of the advancing suspended trolley hits the guide part of the backstop plate, the inner hole of the backstop plate rotates a certain angle on the rotating shaft, and the backstop plate is lifted. When it reaches the rear end of the rear wheel of the suspended trolley, the backstop plate falls due to the counterweight force, stopping the trolley from moving backward. The size of the counterweight force determines whether the trolley returns to its position in time, achieving the effect of preventing back movement.

[0070] Referring to Figure 6, preferably, this embodiment is further provided with a number issuing device, which includes a rotating rod, a pin shaft, a issuing base, and a proximity switch. The issuing base is arranged on one side of the running track, one end of the pin shaft is arranged in the issuing base, one end of the rotating rod is sleeved on the other end of the pin shaft and is rotatably connected to the pin shaft, and the other end of the rotating rod is located on the travel path of the issuing rod of the hanging trolley. The issuing rod is a cylindrical, horizontally mounted long rod installed near the rear wheel of the hanging trolley. When the hanging trolley moves to the trigger signal, the issuing rod pushes the rotating rod to rotate around the pin shaft. The proximity switch detects the rotation of the rotating rod and generates a sensing signal, which is sent to the stopper. The stopper extends the stop plate to block the hanging trolley. The pin shaft and the issuing rod are parallel to each other and perpendicular to the travel direction of the hanging trolley. The rotating rod is arranged perpendicular to the pin shaft and the issuing rod.

[0071] Preferably, in this embodiment, a protective cover is installed on each side of the link track, and the contact part with the suspension trolley is blocked with a brush strip to prevent paint powder from splashing onto the positioning rotating assembly.

[0072] Finally, the working steps of this embodiment are briefly described:

[0073] First, the accumulation chain runs in a straight line on the accumulation track located above. The push head pulls the suspended trolley on the running track below to run in a straight line together. The trolley's front wheel triggers the backstop plate to lift, and the trolley moves forward. The trolley's signal rod lifts the signal device's crossbar upward, and the induction switch sends a signal to the stopper. The stop plate is extended by the cylinder, and the trolley continues to move forward. After the trolley lifting claw inserts into the stopper's inclined surface, the lifting and lowering pressure is pressed down, the trolley stops, the backstop returns to its position, and the backstop plate falls, blocking the trolley's rear wheel. Then, the positioning gear is extended by the second linear cylinder, positioned in a V shape on the driven gear, and the first linear cylinder pushes the driving gear and the driven gear into gear meshing. Finally, the robot sprays paint on half of the capacitor surface, stops spraying, and returns to its original position. The motor and reduction gear of the drive mechanism drive the drive gear to rotate and stop running at about 180°. During this process, the sliding column (detection unit) and spring positioning of the elastic positioning assembly of the suspension trolley are used to position the trolley 180° tightly to prevent the suspension trolley from continuing to rotate. The robot continues to spray paint on the remaining part of the capacitor surface. After the painting is completed, the suspension trolley continues to move forward and enters the next process.
