[0002] A coating line is a production line that performs a series of operations. Its process flow includes pretreatment, powder coating, and heat curing. For long-distance transport, conveyor belts are typically used for transferring goods. However, for shorter-distance transport, the use of conveyor belts is wasteful, and rollers are usually used instead. On a coating line, various processes are usually connected by conveyor roller beds. In some processes, workpieces may need to stop, but repeatedly starting and stopping the conveyor roller beds is impractical for continuous production. Manually stopping them is time-consuming and labor-intensive. Therefore, a workpiece blocking and lifting device for coating conveyor roller beds is proposed. Utility Model Content

[0018] Example 1:
[0019] like Figure 1-4 As shown, the present invention provides a workpiece blocking and lifting device for a coating conveyor roller bed, comprising: a base plate 1, a blocking mechanism, and a lifting mechanism; the base plate 1 is located below the conveyor roller bed; the lifting mechanism includes a lifting drive unit and four lifting execution units; the blocking mechanism, the lifting drive unit, and the four lifting execution units are all mounted on the base plate 1; the blocking mechanism is used to block the workpiece on the conveyor roller bed; the upper end of the lifting execution unit extends between two adjacent idler rollers 29 on the conveyor roller bed, and is used to lift the workpiece blocked by the blocking mechanism and remove it from the idler rollers 29; the lifting drive unit is used to drive the four lifting execution units to lift and lower synchronously.
[0020] The blocking mechanism blocks the workpiece on the conveyor roller bed, stopping it at a designated position to facilitate the lifting execution unit to lift the workpiece upwards. The lifting drive unit synchronously drives four lifting execution units to rise and fall, lifting the workpiece upwards and allowing it to detach from the idler roller 29 for a period of time as needed. Afterwards, the four lifting drive units place the workpiece back onto the idler roller 29, and the blocking mechanism no longer blocks the workpiece, allowing the conveyor roller bed to continue transporting the workpiece to the next process flow. This method can be well applied to coating production lines, eliminating the need for repeated starting and stopping of the conveyor roller bed or manual stopping, thus improving the automation level of the coating line.
[0021] Furthermore, the lifting drive unit includes a lifting drive motor 9, a lifting drive tube 8, a lifting internal thread tube 6, and a U-shaped fork 2;
[0022] Two parallel rods of the U-shaped fork 2 are rotatably mounted through the fork, and two lifting protrusions 4 are provided on the two parallel rods of the U-shaped fork 2. The vertical sidewall of the lifting protrusion 4 is set as a ramp 5. A drive wheel 14 that travels laterally on the U-shaped fork 2 is rotatably mounted on the lower end of the four lifting execution units. The four drive wheels 14 travel to the corresponding lifting protrusions 4 through the four ramps 5 respectively.
[0023] The lifting drive tube 8 is horizontally fixed on the base plate 1; the lifting internal thread tube 6 is telescopically mounted on the lifting drive tube 8, and the other end is fixed to the middle of the connecting rod of the U-shaped fork 2; a drive guide groove 7 is provided on the lifting internal thread tube 6 along the axial direction; a drive guide slider that slides in cooperation with the drive guide groove 7 is provided on the inner wall of the lifting drive tube 8; the lifting drive motor 9 is mounted on the lifting drive tube 8; a lifting drive screw threaded on the lifting internal thread tube 6 is connected to the output shaft of the lifting drive motor 9.
[0024] The four lifting bosses 4 on the U-shaped fork 2 can be used to synchronously drive the four lifting execution units. The lifting drive motor 9 drives the lifting drive screw to rotate, causing the lifting internal thread tube 6 to extend and retract along the lifting drive tube 8, thereby driving the U-shaped fork 2 to move laterally. During the lateral movement of the U-shaped fork 2, the four drive wheels 14 travel to the corresponding lifting bosses 4 via the four ramps 5, or travel from the corresponding lifting bosses 4 to the upper side of the U-shaped fork 2 via the four ramps 5, thereby realizing the lifting and lowering drive of the lifting execution units. The drive wheels 14 can reduce friction and wear.
[0025] Furthermore, the lifting execution unit includes a lifting guide tube 11, a lifting internal thread tube 12, and a lifting screw 16; multiple support rods 10 with their lower ends fixed to the base plate 1 are vertically fixed on the lifting guide tube 11, and the lifting guide tube 11 is axially vertical; the lifting internal thread tube 12 is slidably installed through the lifting guide tube 11; a lifting guide groove 13 is provided on the lifting internal thread tube 12 along the axial direction; a lifting guide slider that slides in cooperation with the lifting guide groove 13 is provided on the inner wall of the lifting guide tube 11; the lifting screw 16 is threaded onto the upper end of the lifting internal thread tube 12, and an anti-loosening nut 15 for preventing loosening is threaded onto the lifting screw 16; the upper end of the lifting screw 16 is used to extend between two adjacent idlers 29 on the conveyor roller bed; a support plate 17 is fixed on the upper end of the lifting screw 16; and a drive wheel 14 is rotatably installed on the lower end of the lifting internal thread tube 12.
[0026] The lifting guide tube 11 provides a vertical guide for the lifting internal thread tube 12; the cooperation between the lifting internal thread tube 12, the lifting screw 16 and the anti-loosening nut 15 can adjust the height of the support plate 17 as needed, ensuring that the workpiece can be removed from the roller 29 after the support plate 17 moves up and lifts the workpiece, and preventing the workpiece from jumping due to repeated action of the roller 29.
[0027] Furthermore, the blocking mechanism includes a swing plate 24, a blocking plate 25, and a blocking drive unit; two hinge seats 18 are fixed on the base plate 1; one side edge of the swing plate 24 is rotatably mounted on the two hinge seats 18 via a rotating shaft 28; the blocking drive unit is mounted on the base plate 1 and is used to drive the swing plate 24 to swing; the lower end of the blocking plate 25 is fixed on the swing plate 24, and the upper edge is used to extend between two adjacent idlers 29 on the conveyor roller bed, and the upper edge of the blocking plate 25 is higher than the idlers 29; a position sensor 27 and a flexible pad 26 are installed on the upper edge of the blocking plate 25.
[0028] The oscillating plate 24, driven by the blocking drive unit, drives the blocking plate 25 to swing. When the swing end of the oscillating plate 24 is at its highest point, the upper edge of the blocking plate 25 is higher than the idler roller 29, allowing the blocking plate 25 to block the workpiece on the transport roller bed. The position sensor 27 detects the position of the workpiece. When the position sensor 27 detects the workpiece, the lifting drive unit drives four lifting execution units to rise and lift the workpiece. After the lifting execution units lower the workpiece, the position sensor 27 detects the workpiece again. At this time, the blocking drive unit drives the oscillating plate 24 to move the blocking plate 25 downward, so that the workpiece is transported by the transport roller bed to the next process flow. After a period of time, the blocking drive unit drives the oscillating plate 24 to reset the blocking plate 25 and continue to block the next workpiece.
[0029] Furthermore, the blocking drive unit includes a blocking drive motor 19, a blocking guide tube 20, a blocking internal thread tube 21, and two hinge rods 23; the blocking guide tube 20 is oscillatingly mounted on the base plate 1; the blocking drive motor 19 is mounted on the blocking guide tube 20; one end of the blocking internal thread tube 21 is telescopically mounted on the blocking guide tube 20; a blocking limiting groove 22 is provided along the length direction on the blocking internal thread tube 21, and a blocking limiting slider that slides in cooperation with the blocking limiting groove 22 is provided on the inner wall of the blocking guide tube 20; a blocking drive screw threaded onto the blocking internal thread tube 21 is connected to the output shaft of the blocking drive motor 19; one end of each of the two hinge rods 23 is respectively hinged to the base plate 1 and the swing plate 24, and the other end is oscillatingly mounted on the other end of the blocking internal thread tube 21.
[0030] The blocking drive motor 19 drives the blocking drive screw to rotate, the blocking internal thread tube 21 extends and retracts along the blocking guide tube 20, and the two hinge rods 23 are linked with the blocking internal thread tube 21 to realize the swing drive of the swing plate 24.
[0031] In the workpiece blocking and lifting device for coating conveyor roller bed provided by this utility model, both the lifting drive motor 9 and the blocking drive motor 19 are existing stepper motors; the position sensor 27 is an existing position sensor.
[0032] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
