Description

Technical Field

[0001] This utility model belongs to the field of pad printing equipment technology, and in particular relates to a pad printing robot. Background Technology

[0002] Pad printing robots are core automated equipment in pad printing production lines. They are mainly used for gripping and transferring workpieces, enabling automated transfer of workpieces between the pad printing station and subsequent processing / unloading stations, and greatly improving the efficiency and automation of pad printing operations.

[0003] Traditional pad printing robots generally use a single-jaw structure for workpiece gripping. This structure can meet basic operational needs when gripping workpieces of standard size and regular shape, but it has the following shortcomings when gripping relatively slender workpieces (such as long strip-shaped hardware parts, plastic profiles, pen barrels, etc.):

[0004] The length dimension of a slender workpiece is much larger than its width / diameter dimension. A single gripper can only hold the workpiece at a single point. The center of gravity of the workpiece is prone to deviate from the gripping point, and the workpiece is prone to imbalance. This causes the workpiece to shake, tilt, or even fall out of the gripper during the transfer process, making it impossible to complete a stable workpiece transfer. Utility Model Content

[0042] In one embodiment of this utility model, such as Figures 1-8 As shown, a pad printing robot is provided, including a housing 1, a frame 2, an electrical control box 3, a clamping mechanism 4, a conveying mechanism 5, and a drying mechanism 6. The frame 2 and the electrical control box 3 are both fixed to the housing 1. The electrical control box 3 is electrically connected to the clamping mechanism 4, the conveying mechanism 5, and the drying mechanism 6 respectively. The clamping mechanism 4 is fixed to the frame 2 and is located above the conveying mechanism 5. The conveying mechanism 5 is fixed to the housing 1 and passes through the drying mechanism 6. The drying mechanism 6 is fixed to the conveying mechanism 5.

[0043] The clamping mechanism 4 includes a pushing component 41, a guiding component 42, a lifting component 43, and a clamping component 44. The pushing component 41 is fixed to the frame 2. The guiding component 42 is fixed to both the frame 2 and the pushing component 41. The lifting component 43 is fixed to the guiding component 42. The clamping component 44 is fixed to the lifting component 43. The clamping component 44 includes a first pneumatic gripper 441 and a second pneumatic gripper 442. The first pneumatic gripper 441 and the second pneumatic gripper 442 are arranged in parallel and at intervals, and are both fixed to the lifting component 43. The first pneumatic gripper 441 and the second pneumatic gripper 442 are both electrically connected to the electrical control box 3.

[0044] In another embodiment of this utility model, the pushing component 41 includes a pushing cylinder 411 and a pushing plate 412. The pushing cylinder 411 is fixedly connected to the frame 2, and the pushing plate 412 is fixedly connected to the pushing cylinder 411 and the guide component 42 respectively. The pushing cylinder 411 is electrically connected to the electrical control box 3. The guide component 42 includes a guide cylinder 421 and a guide rod 422. The guide cylinder 421 is fixedly connected to the pushing plate 412 and slidably connected to the guide rod 422. Two guide components 42 are provided, and both are fixedly connected to the frame 2. The lifting component 43 includes a lifting base plate 431, a lifting cylinder 432, and a lifting plate 433. The lifting base plate 431 is fixedly connected to the pushing plate 412, the lifting cylinder 432 is fixedly connected to the lifting base plate 431, and the lifting plate 433 is fixedly connected to the lifting cylinder 432. The first pneumatic gripper 441 and the second pneumatic gripper 442 are both fixedly connected to the lifting plate 433. The lifting cylinder 432 is electrically connected to the electrical control box 3.

[0045] The clamping mechanism 4 operates as follows: The electrical control box 3, acting as the control core, sends action commands to the pushing component 41, the lifting component 43, and the clamping component 44; the lifting cylinder 432 (electrically connected to the electrical control box 3) extends and retracts upon command, causing the first and second pneumatic grippers 442, fixed to the lifting plate 433, to rise and fall synchronously until the grippers descend to the preset height of the workpiece to be clamped; the electrical control box 3 controls the two pneumatic grippers to close, stably clamping the workpiece (two-point support for the double grippers prevents the center of gravity of slender workpieces from shifting); the pushing cylinder 411 (electrically connected to the electrical control box 3) extends and retracts upon command, causing the pushing plate 412, fixed to its output end, to move horizontally; simultaneously, the pushing... The guide cylinder 421 at the bottom of the feeding plate 412 (slidably connected to the guide rod 422 of the guide assembly 42, and the guide rod 422 is fixed to the frame 2) slides along the guide rod 422 to ensure that the pushing plate 412 and the lifting assembly 43 and clamping assembly 44 (including the workpiece) move horizontally and stably, avoiding tilting and deviation; when the assembly is moved to the target station (such as above the conveyor belt 56), the electrical control box 3 controls the lifting cylinder 432 to extend again, driving the gripper and workpiece down to the preset placement height, and then controls the gripper to open to complete the workpiece placement; each assembly moves in the opposite direction (the lifting cylinder 432 retracts and the pushing cylinder 411 resets), waiting for the next clamping command, and enters the cycle.

[0046] In another embodiment of this utility model, the conveying mechanism 5 includes a conveying bracket 51, a conveying motor 52, a driving pulley 53, a driven pulley 54, a conveying belt 55, a conveying roller, and a conveying belt 56. The conveying bracket 51 is fixed to the housing 1, the conveying motor 52 is fixed to the conveying bracket 51, the driving pulley 53 is fixed to the conveying motor 52, the driven pulley 54 is rotatably connected to the conveying bracket 51, and the conveying belt 55 is fixedly wound around the driving pulley 53 and the driven pulley 54 respectively. The conveying roller is fixed to the driven pulley 54 and rotatably connected to the conveying bracket 51. The conveying belt 56 is fixedly wound around the conveying roller and is disposed below the first pneumatic gripper 441 and the second pneumatic gripper 442.

[0047] The conveying mechanism 5 operates as follows: The conveying motor 52, which is electrically connected to the control box 3, starts after receiving a command, driving the drive pulley 53, which is fixed to its output shaft, to rotate synchronously. The drive pulley 53 transmits power to the driven pulley 54, which is rotatably connected to the conveying bracket 51, through the conveying belt 55, so that the driven pulley 54 rotates in the same direction as the drive pulley 53. Since the conveying roller is fixed to the driven pulley 54, the driven pulley 54 rotates synchronously, driving the conveying roller (rotatably connected to the conveying bracket 51) to rotate. The conveying belt 56, which is wound around the conveying roller, moves smoothly in a preset direction (towards the drying mechanism 6) under the rotation drive of the conveying roller. The conveying belt 56 is located below the first pneumatic gripper 441 and the second pneumatic gripper 442. After receiving the workpiece placed by the gripper, it stably conveys the workpiece to the subsequent station (such as the drying mechanism 6), completing the conveying operation.

[0048] In another embodiment of this utility model, the drying mechanism 6 includes an insulation shell 61, an insulation cover 62, a first electric heating tube 63, and a second electric heating tube 64. The insulation shell 61 and the insulation cover 62 are both fixed to the conveyor support 51. The insulation cover 62 is disposed inside the insulation shell 61. The first electric heating tube 63 and the second electric heating tube 64 are sequentially fixed inside the insulation cover 62 and arranged in parallel and symmetrically. The first electric heating tube 63 and the second electric heating tube 64 are disposed above the conveyor belt 56. A drying component 7 is disposed on one side of the drying mechanism 6. The drying component 7 is fixed to the insulation shell 61. The drying component 7 includes a ventilation cover 71 and a fan 72. The ventilation cover 71 is fixed to the insulation shell 61 and is provided with multiple ventilation holes 711. Two fans 72 are provided and are both fixed to the ventilation cover 71. The fans 72 are disposed below the ventilation holes 711.

[0049] The drying mechanism 6 and the air-drying component 7 operate as follows: The workpiece (placed on the conveyor belt 56 by the clamping mechanism 4) moving with the conveyor belt 56 enters the closed drying space formed by the insulation shell 61 (fixed to the conveyor support 51) and the internal insulation cover 62 through the opening of the insulation shell 61. The insulation shell 61 and the insulation cover 62 work together to reduce heat loss and maintain the stability of the drying environment. The electrical control box 3 sends instructions to the first heating tube 63 and the second heating tube 64. The two heating tubes (fixed sequentially inside the insulation cover 62, parallel and symmetrical, and located above the conveyor belt 56) start and release heat to heat the workpiece in stages during the conveying process. The workpiece is first preheated by the first heating tube 63 and then deeply dried by the second heating tube 64 to ensure that the pad printing ink is heated evenly and avoid localized heating. If the workpiece is not fully dried or overheated; when the workpiece has completed heating and drying and moves with the conveyor belt 56 to the air drying component 7 on one side of the drying mechanism 6, the control box 3 controls the two fans 72 on the ventilation hood 71 (fixed to the heat insulation shell 61) to start; the fans 72 (located below the ventilation holes 711) rotate to generate airflow, which accelerates the air circulation in the drying space through the multiple ventilation holes 711 of the ventilation hood 71. On the one hand, it quickly removes excess heat from the surface of the workpiece to prevent the ink from being damaged by continuous high temperature, and on the other hand, it further strengthens the adhesion of the ink. At the same time, the ventilation holes 711 balance the air pressure in the drying space to avoid the accumulation of hot air and uneven heating of the workpiece. After heating, drying and air drying, the workpiece continues to move with the conveyor belt 56 and leaves the drying mechanism 6 from the other end of the heat insulation shell 61 to the unloading stage.

[0050] In another embodiment of this utility model, a feeding assembly 8 is provided on one side of the conveyor belt 56. The feeding assembly 8 includes a feeding seat 81, an adjusting bolt 82, an adjusting plate 83, a feeding hopper 84, and a feeding shaft 85. The feeding seat 81 is fixed to the conveyor bracket 51, and the adjusting bolt 82 is threadedly connected to the feeding seat 81. The adjusting plate 83 is fixedly connected to the adjusting bolt 82 and the feeding hopper 84 respectively. The feeding hopper 84 is provided on one side of the conveyor belt 56 and fixed to the feeding shaft 85. The feeding shaft 85 is rotatably connected to the feeding seat 81.

[0051] The working process of the feeding component 8 is as follows:

[0052] According to the dimensions (length, weight) of the slender workpiece to be unloaded, rotate the adjusting bolt 82 threaded to the unloading base 81. The adjusting bolt 82 drives the adjusting plates 83 fixed at both ends to move up and down. Since the unloading hopper 84 is fixed to the unloading shaft 85 rotatably connected to the unloading base 81, the adjusting plates 83 pull the unloading hopper 84 to rotate synchronously around the unloading shaft 85 until the tilt angle of the unloading hopper 84 (e.g., 30-60°) matches the smooth sliding requirement of the workpiece, completing the pre-adjustment. The workpiece after being processed by the drying mechanism 6 moves to the output end with the conveyor belt 56. Since the unloading hopper 84 is set on one side of the conveyor belt 56, the workpiece naturally transitions from the surface of the conveyor belt 56 into the unloading hopper 84. The arc structure of the unloading hopper 84 can avoid the workpiece from being damaged by impact. The workpiece falling into the unloading hopper 84 slides along the pre-adjusted tilt angle and finally slides smoothly into the collection container below, completing the entire unloading operation. If the workpiece specifications are changed later, the angle of the unloading hopper 84 can be adjusted to ensure adaptability.

[0053] The pad printing robot provided in this application operates as follows:

[0054] Workpiece clamping: The electric control box 3 controls the piston rod of the lifting cylinder 432 to extend, driving the lifting plate 433 and the first pneumatic gripper 441 and the second pneumatic gripper 442 to descend to the position to clamp the slender workpiece; then the electric control box 3 controls the two pneumatic grippers to close synchronously, clamping the workpiece at two positions in the length direction, forming two-point support to ensure the stability of the workpiece's center of gravity.

[0055] Workpiece transfer: The control box 3 controls the piston rod of the lifting cylinder 432 to retract, which drives the clamped workpiece to rise to the preset height; then controls the piston rod of the pushing cylinder 411 to extend, which drives the pushing plate 412 to move horizontally along the guide rod 422, and transfers the workpiece to the top of the conveyor belt 56.

[0056] Workpiece placement: The control box 3 controls the piston rod of the lifting cylinder 432 to extend again, placing the workpiece on the conveyor belt 56, and then controls the two pneumatic grippers to open, completing the workpiece placement;

[0057] Conveying and Drying: The electrical control box 3 controls the start of the conveyor motor 52, which drives the drive pulley 53 to rotate. The drive pulley 54 and the conveyor roller rotate through the conveyor belt 55, which in turn drives the conveyor belt 56 to move and convey the workpiece into the heat preservation cover 62 of the drying mechanism 6. The electrical control box 3 controls the first heating tube 63 and the second heating tube 64 to heat the workpiece and dry it in stages. At the same time, it controls the fan 72 to rotate, accelerate the air circulation in the drying chamber, and improve the drying efficiency.

[0058] Workpiece unloading: After drying, the workpiece moves to the output end with the conveyor belt 56 and falls into the unloading hopper 84. By adjusting the tilt angle of the unloading hopper 84, the workpiece can be smoothly slid into the collection container to complete the entire operation process.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
