Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0017] according to Figures 1 to 3 As shown, one embodiment of the present invention provides a jig tracking powder cleaning device 200 for a coating production line. The coating production line includes a first conveyor line 100, and the first conveyor line 100 is suitable for conveying a coating jig 300 for carrying a workpiece, and a powder cleaning station is arranged on the conveying path of the first conveyor line 100. The powder cleaning station includes a first position and a second position arranged downstream of the first position along the extension direction of the conveying path.

[0018] according to Figure 5 and Figure 6 As shown, in this embodiment, the first conveyor line 100 is a ground conveyor chain (or ground chain conveyor), and the workpiece to be operated is a car wheel hub. The first conveyor line 100 includes a conveying track 101, a conveying chain 102 and a first driving mechanism (not shown in the figure), the conveying chain 102 is movably arranged on the conveying track 101, the painting jig 300 is installed on the conveying chain 102, and the first driving mechanism is connected to the conveying chain 102 in a transmission manner and is suitable for driving the conveying chain 102 to move along the conveying track 101. Among them, the first driving mechanism is a conveying motor. The painting jig 300 includes a jig seat 301, a jig rod 302 and a support portion 303, the jig seat 301 is fixedly supported on the conveying chain 102, the jig rod 302 extends in the up and down direction and is rotatably arranged on the jig seat 301, the support portion 303 is fixedly supported on the upper end of the jig rod 302 and is suitable for supporting the workpiece, and the lower end of the jig rod 302 is fixedly installed with a transmission sprocket 304.

[0019] The first conveyor line 100 conveys the coating jig 300 for carrying the automobile wheel hub to the powder cleaning station along the conveying path of the conveyor track 101 , and the coating jig 300 moves from the first position to the second position of the powder cleaning station.

[0020] according to Figures 7 to 9 As shown, the jig tracking powder cleaning device 200 includes a support frame 201, a movable seat 202, an air blowing nozzle 203 and a reset mechanism 204. The movable seat 202 is movably arranged on the support frame 201 between a first position and a second position. The movable seat 202 is constructed to be driven by the coating jig 300 to move to the second position when the coating jig 300 moves to the first position, and to be disengaged from the coating jig 300 when the coating jig 300 leaves the second position. The air blowing nozzle 203 is arranged on the movable seat 202 and is suitable for blowing the coating jig 300. The air blowing nozzle 203 is constructed to be suitable for airflow communication with an air source (not shown in the figure). The reset mechanism 204 is transmission-connected to the movable seat 202 and is constructed to drive the movable seat 202 to return from the second position to the first position when the coating jig 300 leaves the second position and is disengaged from the movable seat 202.

[0021] By setting a powder cleaning station on the conveying path of the first conveyor line 100, the jig tracking powder cleaning device 200 is arranged at the powder cleaning station, the powder cleaning station has a first position and a second position extending along the conveying path of the first conveyor line 100 and arranged downstream of the first position, the movable seat 202 of the jig tracking powder cleaning device 200 can reciprocate between the first position and the second position, and the movable seat 202 is provided with a blowing nozzle 203 suitable for blowing the coating jig 300. When the coating jig 300 moves to the first position, the movable seat 202 is driven to move to the second position together, during which the coating jig 300 is blown by the blowing nozzle 203, and the coating jig 300 is disengaged from the movable seat 202 when the coating jig 300 leaves the second position, so that when the coating jig 300 passes through the powder cleaning station, the blowing nozzle 203 can automatically track the coating jig 300 and blow the coating jig 300, and the cleaning effect is better.

[0022] Specifically, according to Figures 8 to 12As shown, the support frame 201 is provided with a moving track 211 extending from the first position to the second position, and the bottom of the moving seat 202 is provided with a moving wheel 226, which is supported on the moving track 211 and can move along the moving track 211. The moving seat 202 is provided with a blocking member 222, which extends outward along a direction perpendicular to the moving track 211 (that is, the second direction, which is perpendicular to the first direction and the second direction is a direction extending forward and backward) so that the coating jig 300 is blocked by the blocking member 222 when it moves to the first position, thereby driving the moving seat 202 to move together. In this embodiment, the blocking member 222 is supported on the moving seat 202 by a sliding module 223 and connected to the moving seat 202 by a spring 227. Among them, the sliding module 223 includes two pulleys 225 rotatably arranged on the moving seat 202, and the blocking member 222 is slidably matched between the two pulleys 225 through a slide plate 224. This facilitates the blocking member 222 to be able to be extended and disengaged when encountering obstacles in the second direction. For example, when the painting jig 300 moves to the second position and disengages from the blocking member 222 of the movable seat 202, it can avoid the blocking member 222 and the painting jig 300 from getting stuck. In other embodiments, the sliding module 223 may also be a structure of a slide rail slider or a slide groove guide rail, or the sliding module 223 may not be provided, and the blocking member 222 may be directly fixed on the movable seat 202, which is not specifically limited.

[0023] The movable seat 202 is fixedly supported with a purge rack 216, and has a plurality of air blowing nozzles 203, which are arranged on the purge rack 216 and communicated with the air source airflow through the air blowing pipe, and the plurality of air blowing nozzles 203 are distributed on opposite sides of the coating jig 300. In other embodiments, only one air blowing nozzle 203 may be provided; and the distribution of the plurality of air blowing nozzles 203 on the purge rack 216 may be all arranged on one side of the purge rack 216, or evenly distributed on opposite sides of the purge rack 216, so as to facilitate uniform purge of the coating jig 300, and there is no specific limitation.

[0024] according to Figure 4 and Figure 7 As shown, the reset mechanism 204 includes a reset frame 212, a rope 213, a plurality of fixed pulleys 214 and a counterweight 215. The plurality of fixed pulleys 214 are rotatably arranged on the reset frame 212. One end of the rope 213 passes through the plurality of fixed pulleys 214 and is connected to the movable seat 202. The other end of the rope 213 is connected to the counterweight 215.

[0025] When the painting jig 300 moves to the first position, it is blocked by the blocking member 222 on the moving seat 202, thereby driving the moving seat 202 to move from the first position to the second position. During this period, the blowing nozzle 203 on the moving seat 202 blows at the painting jig 300 to clean the dust on the painting jig 300. At the same time, the moving seat 202 pulls the counterweight 215 up through the rope 213. When the painting jig 300 moves and leaves the second position, the painting jig 300 is disengaged from the blocking member 222 on the moving seat 202, and the counterweight 215 falls back under the action of its own gravity, thereby pulling the moving seat 202 to move in the opposite direction. The moving seat 202 drives the blowing nozzle 203 to return from the second position to the first position, preparing to blow the next painting jig 300 that moves to the first position.

[0026] according to Figure 7 , Fig. 9 and Fig.13 As shown, when the coating jig 300 moves from the first position to the second position and purges dust through the air nozzle 203 during the movement, in order to facilitate driving the coating jig 300 to rotate, the purging is more thorough. The jig tracking powder cleaning device 200 also includes a tracking rotation mechanism 205 suitable for driving the jig rod 302 to rotate, and the tracking rotation mechanism 205 includes a driving motor 206, a driving sprocket 207, a plurality of driven sprockets 208 and a transmission chain 209. The driving sprocket 207 is mounted on the driving motor 206, and the plurality of driven sprockets 208 are rotatably arranged on the support frame 201. The transmission chain 209 is connected between the driving sprocket 207 and the plurality of driven sprockets 208. The transmission chain 209 is constructed to mesh with the transmission sprocket 304 when the coating jig 300 moves to the first position, and to disengage from the transmission sprocket 304 when the coating jig 300 leaves the second position.

[0027] In this embodiment, in order to facilitate the arrangement of the transmission chain 209 and enable the transmission chain 209 to move better and mesh with the transmission sprocket 304 on the coating jig 300, a chain track 210 extending from a first position to a second position is provided on the support frame 201, and the transmission chain 209 is supported on the chain track 210. There are multiple driven sprockets 208, and two chain tracks 210 are provided. The two chain tracks 210 are arranged on the support frame 201 at intervals, and multiple driven sprockets 208 are distributed around the support frame 201. In other embodiments, only one driven sprocket 208 can be provided, and the transmission chain 209 can be connected between the driving sprocket 207 and the driven sprocket 208, and there is no specific limitation.

[0028] When the painting jig 300 moves to the first position, the drive sprocket 304 on the painting jig 300 engages with the drive chain 209 of the tracking rotation mechanism 205, so that when the painting jig 300 moves from the first position to the second position, the drive chain 209 of the tracking rotation mechanism 205 drives the painting jig 300 to rotate, and the air blowing nozzle 203 blows and cleans the rotating painting jig 300, which has a better cleaning effect on the painting jig 300.

[0029] according to Figures 1 to 3 as well as Fig.14 As shown, in order to facilitate the collection of dust and dirt blown off the painting jig 300, the jig tracking powder cleaning device 200 also includes a dust collection mechanism 217, and the dust collection mechanism 217 includes a collection frame 218, a collection shell 219 and an exhaust duct 220. The collection shell 219 is supported on the collection frame 218 and has a collection chamber 221 for the painting jig 300 to pass through. The collection chamber 221 extends from a first position to a second position, and one end of the exhaust duct 220 is connected to the collection chamber 221 in an airflow manner, and the other end is connected to a negative pressure source (not shown in the figure).

[0030] In this embodiment, an opening is provided on the collection shell 219, and a portion of the purge rack 216 is provided through the opening and extends the air blowing nozzle 203 into the collection chamber 221 of the collection shell 219. The negative pressure source is an air compressor. In other embodiments, the air blowing nozzle 203 and the purge rack 216 can also be completely accommodated in the collection chamber 221, and the negative pressure source can also be a negative pressure fan, a vacuum pump, etc., which is not specifically limited.

[0031] When the painting jig 300 moves from the first position to the second position, the painting jig 300 is purged through the blowing nozzle 203, and the dust blown off is collected by the collecting chamber 221 and sucked away by the negative pressure source through the exhaust duct 220. The cleaned dust can be sucked away in time to avoid polluting the workshop environment.

[0032] In order to save energy, the driving motor 206, the negative pressure source and the air source can be turned on again when the coating jig 300 passes through the powder cleaning station. The jig tracking powder cleaning device 200 also includes a control system, which includes a controller, a first sensor and a second sensor. The first sensor is set at a first position and is used to detect whether the coating jig 300 has reached the first position. The second sensor is set at a second position and is used to detect whether the coating jig 300 has left the second position. The controller is connected to the first sensor and the second sensor by signal and is constructed to control the air source, the driving motor 206 and the negative pressure source to start based on the detection signal of the first sensor, and to control the air source, the driving motor 206 and the negative pressure source to stop based on the detection signal of the second sensor.

[0033] In this embodiment, the controller is a PLC controller, and the first sensor and the second sensor are position sensors, such as photoelectric sensors. In other embodiments, the controller may also be a control chip, a microcontroller, etc., and the first sensor may also be an infrared sensor, a proximity switch, etc., without specific limitation.

[0034] When the painting jig 300 moves to the first position and moves from the first position to the second position, the first sensor sends a detection signal to the controller, and the controller controls the drive motor 206, the negative pressure source and the air source to start respectively. The painting jig 300 is transported by the first conveyor line 100 and rotates at the same time. The air blowing nozzle 203 performs a blowing operation on the rotating painting jig 300, and the negative pressure source generates a negative pressure airflow from the collection chamber 221 into the exhaust duct 220, and extracts the dust blown into the collection chamber 221.

[0035] When the coating jig 300 leaves the second position, the second sensor sends a detection signal to the controller, and the controller controls the driving motor 206, the negative pressure source and the air source to stop respectively. The coating jig 300 is transported by the first conveyor line 100 and continues to move downstream.

[0036] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
