Description

Technical Field

[0001] This utility model relates to a transport device, and more particularly to a workpiece transport device for a coating production line. Background Technology

[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 items. However, for shorter-distance transfers, 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 the conveyor roller beds is also time-consuming and labor-intensive. Therefore, a workpiece transport device for coating production lines is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0021] Example 1:

[0022] like Figure 1-6 As shown, the present invention provides a workpiece transport device for a coating production line, comprising: a control box 1, a base plate 11, a transport roller conveyor, a transport mechanism, a clamping and lifting mechanism, and a blocking mechanism; the base plate 11 is located below the transport roller conveyor; the transport roller conveyor is used to transport the transport mechanism; the transport mechanism is used to provide fixed-point support for the workpiece; the clamping and lifting mechanism and the blocking mechanism are both installed on the upper side of the base plate 11; the blocking mechanism is used to block the transport mechanism on the transport track; the clamping and lifting mechanism is used to lift the transport mechanism blocked by the blocking mechanism; the control box 1 is installed on the transport roller conveyor; a controller and a wireless communication module electrically connected to the controller are provided inside the control box 1; multiple operation buttons 2 electrically connected to the controller are provided on the control box 1; the transport roller conveyor, the clamping and lifting mechanism, and the blocking mechanism are all driven and controlled by the controller.

[0023] The workpiece is supported at a fixed point by the transport mechanism, which can adapt to the support of workpieces of different shapes. The controller controls the transport rollers to move the transport mechanism. The blocking mechanism blocks the transport mechanism on the transport rollers and can stop the transport mechanism at a designated position as needed. The clamping and lifting mechanism clamps and lifts the transport mechanism away from the transport rollers to prevent the transport mechanism from jumping due to the action of the transport rollers. After a period of time, the clamping and lifting mechanism puts the workpiece back on the transport rollers, and the blocking mechanism no longer blocks the transport mechanism, allowing the transport rollers to transport the workpiece to the next processing step. It can be well applied to the coating production line, eliminating the need to repeatedly start and stop the transport rollers or manually stop them, thus improving the automation level of the coating production line. The operation button 2 allows the operator to directly control the transport rollers, clamping and lifting mechanism and blocking mechanism through the controller.

[0024] Furthermore, the conveyor roller conveyor includes a mounting frame 3, a conveyor drive motor 8, a drive chain transmission pair, and multiple synchronous chain transmission pairs; the drive chain transmission pair includes a driving sprocket 9, a driven sprocket, and a drive chain 10; the synchronous chain transmission pair includes a synchronous chain 7 and two synchronous sprockets 6; support feet 4 are provided at the four corners of the mounting frame 3; multiple idler rollers 5 are rotatably connected between the frame rods in the two length directions of the mounting frame 3; the two synchronous sprockets 6 of the synchronous chain transmission pair are respectively installed on the ends of two adjacent idler rollers 5, and the synchronous chain 7 is driven and connected to the two synchronous sprockets 6; each pair of adjacent idler rollers 5 is connected by a synchronous chain transmission pair; the conveyor drive motor 8 is installed on a support foot 4 and is electrically connected to the controller through a conveyor drive circuit; the driving sprocket 9 is installed on the output shaft of the conveyor drive motor 8; the driven sprocket is synchronously rotated and installed on the outermost idler roller 5; the drive chain 10 is driven and connected to the driving sprocket 9 and the driven sprocket.

[0025] The conveyor drive motor 8 operates under the control of the controller. The conveyor drive motor 8 drives the outermost idler roller 5 to rotate through the drive chain transmission pair. Each idler roller 5 rotates synchronously under the drive of each synchronous chain transmission pair, thereby realizing the transportation of the consignment mechanism.

[0026] Furthermore, the blocking mechanism includes a blocking drive unit, a swing rod 16, and a blocking plate 17; the blocking drive unit includes a blocking drive motor 12, a blocking guide tube 13, and a blocking internal thread tube 14; a hinge seat 20 is provided on the base plate 11; one end of the swing rod 16 is rotatably mounted on the hinge seat 20, and the other end is fixed to the lower edge of the blocking plate 17; the blocking guide tube 13 is swingably mounted on the upper side of the base plate 11; the blocking internal thread tube 14 is telescopically mounted on the blocking guide tube 13; two hinge rods 15 are swingably mounted on the end of the blocking internal thread tube 14, and the ends of the two hinge rods 15 are respectively hinged to the base plate 11 and the swing rod 16; the blocking drive motor 12 is mounted on the blocking guide tube 13, drives the blocking internal thread tube 14 to telescopically extend and retract along the blocking guide tube 13 through the blocking drive screw, and is electrically connected to the controller through the blocking drive circuit; a flexible pad 18 is provided on the upper edge of the blocking plate 17; a position sensor 19 electrically connected to the controller is provided on the blocking plate 17.

[0027] The blocking drive motor 12 drives the blocking drive screw to rotate under the control of the controller. The blocking internal thread tube 14 extends and retracts along the blocking guide tube 13. The two hinged rods 15 swing under the drive of the blocking internal thread tube 14 and drive the swing rod 16 to swing. When the swing end of the swing rod 16 is at the highest point, the upper edge of the blocking plate 17 is higher than the idler roller 5, which is used to block the transport mechanism. The position sensor 19 helps the controller detect the transport mechanism. When the position sensor 19 detects the transport mechanism and waits for a period of time, the controller controls the clamping and lifting mechanism to lift and clamp the transport mechanism.

[0028] Furthermore, the clamping and lifting mechanism includes a lifting drive unit and two sets of clamping and lifting units; the lifting drive unit includes a lifting drive motor 26, a lifting drive screw 25, and two drive shafts 22; both drive shafts 22 are rotatably mounted on the upper side of the base plate 11 via a rotating seat 21, and the two drive shafts 22 are parallel to each other; a rotary drive rod 23 is fixed to the end of each of the two drive shafts 22; a rotary internal thread tube 24 and a rotary drive tube are respectively oscillatingly mounted on the end of the two rotary drive rods 23; the lifting drive motor 26 is fixed on the rotary drive tube and electrically connected to the controller through a lifting drive circuit; the lifting drive screw 25 is mated to the output shaft of the lifting drive motor 26, threaded onto the rotary internal thread tube 24, and rotatably passes through the rotary drive tube; both sets of clamping and lifting units are mounted on the two drive shafts 22 and are used to clamp and lift the transport mechanism.

[0029] The lifting drive motor 26 drives the lifting drive screw 25 to rotate under the control of the controller. The rotating internal thread tube 24 moves closer to or away from the rotating drive tube, which increases or decreases the included angle between the two rotating drive rods 23. This causes the two drive shafts 22 to rotate relative to each other. The two drive shafts 22 drive the two clamping lifting units to move closer to each other, thereby lifting and clamping the transport mechanism.

[0030] Furthermore, the clamping and lifting unit includes a clamping guide rod 29, two clamping drive rods 27, and two lifting supports 28; the lower ends of the two clamping drive rods 27 are respectively fixed to two drive shafts 22, and the upper ends are respectively hinged to the lower sides of the two lifting supports 28; guide holes are provided along the length direction on both lifting supports 28; the two ends of the clamping guide rod 29 are slidably inserted into the two guide holes; limiting screws extending out of the corresponding side guide holes are coaxially provided on both ends of the clamping guide rod 29; limiting bolts 30 are threaded onto the extended ends of the two limiting screws; multiple support wheels 33 that travel on the bottom surface of the transport mechanism are rotatably installed on the upper edges of the vertical sides of the two length directions of the lifting supports 28; clamping seats 32 for clamping the transport mechanism are provided on both lifting supports 28; the two lifting supports 28 are always located within the mounting frame 3 in the top view.

[0031] By utilizing the cooperation between the clamping guide rod 29 and the two lifting supports 28, the two lifting supports 28 are always positioned on the same straight line. The two drive shafts 22 drive the two lifting supports 28 to move closer to each other through the two clamping drive rods 27, so that the two clamping seats 32 can clamp the transport mechanism. By utilizing the cooperation between the limiting screw and the limiting bolt 30, the clamping guide rod 29 can be prevented from disengaging, and the movement range of the two lifting supports 28 can be limited to prevent the two lifting supports 28 from disengaging from the mounting frame 3.

[0032] Furthermore, the shipping mechanism includes a shipping plate 34 and multiple shipping units; each shipping unit includes a support base 35, an adjusting shaft 36, and a support pin 39; the lower end of the support base 35 is fixed to the shipping plate 34; a rotating adjusting screw 37 that horizontally penetrates the support base 35 is coaxially fixed to one end of the adjusting shaft 36, and the support pin 39 slides through the other end of the adjusting shaft 36; an adjusting bolt 38 for pressing against the support base 35 is threaded onto the adjusting screw 37, and when the adjusting bolt 38 is pressed against the support base 35, the support pin 39 is pressed tightly against the vertical side of the support base 35; the end of the support pin 39 is a pointed tip.

[0033] By utilizing the cooperation between the support base 35, adjusting shaft 36, support pin 39, adjusting screw 37, and adjusting bolt 38, the height of the tip of the support pin 39 can be adjusted, as can the rotation angle of the support pin 39, so that the support pin 39 can be supported at the bottom recess or edge of the workpiece, improving the stability of the support, and can be adapted to different shapes of workpieces, while allowing the sprayed material to cover the lower edge of the workpiece.

[0034] In the workpiece transport device for coating production lines provided by this utility model, the controller adopts an existing single-chip microcomputer control module; the conveying drive motor 8, the blocking drive motor 12, and the lifting drive motor 26 all adopt existing stepper motors; and the position sensor 19 adopts an existing position sensor.

[0035] 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.
