DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0037] Please refer to Figures 1-4 The present application proposes a pad printing system 1, which can effectively reduce or even avoid the harm of volatile gas to the operator's body.

[0038] The pad printing system 1 includes a conveying module 10, a first pad printing module 20 and a first feeding and discharging module 30. The conveying module 10 includes a support 11, a conveying line 12, a jig 13 and an operation table 14; the conveying line 12 is installed on the support 11; the jig 13 is arranged on the conveying line 12 and is used to carry the product to be processed; and the operation table 14 is installed on the support 11. The first pad printing module 20 is configured to perform pad printing processing on the first surface of the product to be processed. The first pad printing module 20 and the operation table 14 are separately arranged on the two sides of the support 11 along a direction intersecting the conveying direction of the conveying line 12. The first feeding and discharging module 30 is installed on the support 11. The first feeding and discharging module 30 is configured to transfer the product to be processed from the jig 13 to the first pad printing module 20, and transfer the product with one side pad printing completed from the first pad printing module 20 to the empty jig 13.

[0039] The specific structure of the pad printing system 1 is described below. Figures 1-10 The specific structure of the pad printing system 1 is described below.

[0040] As Figures 1-4As shown, the pad printing system 1 includes a conveying module 10, a first pad printing module 20, and a first loading and unloading module 30.

[0041] The conveying module 10 serves as the transmission module of the pad printing system 1. The conveying module 10 includes a support 11, a conveying line 12, a fixture 13, and an operating table 14.

[0042] The support frame 11 serves as the frame for the conveying module 10. The specific structure of the support frame 11 is not limited here, and designers can make reasonable designs according to actual needs; for example, the support frame 11 can be, but is not limited to, a multi-layered structure with upper and lower layers in a long strip shape.

[0043] Conveyor line 12 serves as the assembly line for conveyor module 10. The specific structure of conveyor line 12 is not limited here; designers can design it reasonably according to actual needs. For example, conveyor line 12 includes an upper conveyor (not shown in the figure) and a lower conveyor (not shown in the figure) mounted on support 11. The conveying direction of the upper conveyor is opposite to that of the lower conveyor (e.g., if the upper conveyor moves in the forward direction along the X-axis, the lower conveyor moves in the reverse direction along the X-axis). The upper and lower conveyors are connected by a lifting unit (not shown in the figure). The lifting unit includes a lifting plate and a lifting cylinder. The lifting plate is mounted on the extension rod of the lifting cylinder. The extension rod of the lifting cylinder extends the lifting plate. The lifting cylinder retracts to connect with the end of the upper line, and the lifting plate connects with the end of the lower line by retracting the cylinder's telescopic rod. Thus, the fixture 13 on the upper line transitions from the tail end of the upper line to the lifting plate. The lifting cylinder retracts to connect with the tail end of the lower line, and the fixture 13 on the lifting plate transitions to the tail end of the lower line. The fixture 13 on the lower line transitions from the head end of the lower line to the lifting plate, and the lifting cylinder retracts to connect with the head end of the upper line. The fixture 13 on the lifting plate transitions to the head end of the upper line, thus realizing the cyclic reciprocating motion of the fixture 13.

[0044] The conveyor line 12 is mounted on the bracket 11. The specific connection method between the conveyor line 12 and the bracket 11 is not limited here. Designers can make reasonable designs according to actual needs. In this embodiment, the conveyor line 12 and the bracket 11 can be detachably connected by means of screws, snaps, or plugs, which facilitates the effective replacement of damaged conveyor lines 12 in the future.

[0045] like Figures 1-4 As shown, fixture 13 serves as the carrier of conveying module 10 to hold the product to be processed. The specific structure of fixture 13 is not limited here; designers can design fixture 13 to match the shape of the product to be processed.

[0046] The jig 13 is arranged on the conveying line 12 to be conveyed by the conveying line 12.

[0047] The operation table 14 is used as a worktable of the conveying module 10 to provide sufficient operation space for the operator, and is installed on the support 11. Here, the specific connection mode between the operation table 14 and the support 11 is not limited, and the designer can reasonably design according to the actual needs; for example, the operation table 14 can be, but is not limited to, detachably connected with the support 11 by at least one of screwing, clamping or inserting; for another example, the operation table 14 can also be, but is not limited to, non-detachably connected with the support 11 by welding or riveting.

[0048] The first pad printing module 20 is one of the pad printing modules of the pad printing system 1, and is configured to perform pad printing processing on the first surface of the product to be processed; the specific structure of the first pad printing module 20 will be introduced below.

[0049] The first pad printing module 20 and the operation table 14 are arranged on the two sides of the support 11 along a direction intersecting the conveying direction of the conveying line 12.

[0050] The first pad printing module 20 is one of the pad printing modules of the pad printing system 1, and is configured to perform pad printing processing on the first surface of the product to be processed; the specific structure of the first pad printing module 20 will be introduced below.

[0051] The first pad printing module 20 is one of the pad printing modules of the pad printing system 1, and is configured to perform pad printing processing on the first surface of the product to be processed; the specific structure of the first pad printing module 20 will be introduced below.

[0052] Based on the pad printing system 1 in the embodiment of the present application, the operator stands in front of the operation table 14 and places the product to be processed on the jig 13, the conveying line 12 moves the jig 13 to a suitable position, at this time, the first feeding and discharging module 30 moves the product to be processed from the jig 13 to the first pad printing module 20, the first pad printing module 20 performs pad printing processing on the first surface of the product to be processed, after the pad printing of the first surface of the product to be processed is completed, the first feeding and discharging module 30 moves the product on which the pad printing is completed on one side from the first pad printing module 20 to the empty jig 13; in this way, the first feeding and discharging module 30 replaces manual operation to realize the feeding operation of the product to be processed between the jig 13 and the first pad printing module 20 and the discharging operation of the product on which the pad printing is completed on one side between the first pad printing module 20 and the jig 13, and the operation table 14 and the first pad printing module 20 are separated by the conveying line 12, so the operator does not need to be close to the first pad printing module 20, but only needs to stand in front of the operation table 14 and place the product to be processed on the jig 13, so that the harm of volatile gas generated when the first pad printing module 20 works to the operator's body can be effectively reduced or even avoided.

[0053] As shown in Figures 1-4 , the first pad printing module 20 and the operation table 14 are arranged on the two sides of the support 11 along the direction perpendicular to the conveying direction of the conveying line 12. The conveying direction of the conveying line 12 can be but not limited to the X-axis direction. By arranging the first pad printing module 20 and the operation table 14 on the two sides of the support 11 along the direction perpendicular to the conveying direction of the conveying line 12, the operator standing in front of the operation table 14 can observe the pad printing situation of the product to be processed at any time, so that the operator can timely respond to abnormal situations such as alarm suspension.

[0054] The first pad printing module 20 includes a pad printing machine body 22 and an exhaust hood (not shown in the figure), and the exhaust hood is arranged on the top of the pad printing machine body 22. By designing the exhaust hood, the exhaust hood can timely exhaust the volatile gas generated in the process of the pad printing machine body 22 performing pad printing processing on the product to be processed, so that the harm of the volatile gas to the operator's body can be further effectively reduced or even avoided.

[0055] The operation table 14 is provided with double start buttons 15. After the operator places the product to be processed on the jig 13, the operator can trigger the double start buttons 15 with both hands, and the system can operate normally; the advantage of arranging the double start buttons 15 is that the possibility of accidental operation caused by the operator accidentally triggering one of the buttons can be avoided.

[0056] The operation table 14 is provided with an emergency stop button 16. During the operation of the system, if an accident occurs, the operator can trigger the emergency stop button 16 to make the system immediately in a suspended state, so that the loss caused by the accident can be reduced.

[0057] AsFigures 5-7 As shown, the first pad printing module 20 comprises a pad printing table 21 for carrying the products to be processed.

[0058] The first conveying mechanism 31 is a transmission structure of the first feeding and discharging module 30, and the specific structure of the first conveying mechanism 31 will be described below.

[0059] The first carrier 32 is an intermediate connecting structure of the first feeding and discharging module 30, and the first clamping mechanism 33 and the second clamping mechanism 34 are connected with the driving end of the first conveying mechanism 31 via the first carrier 32. The specific structure of the first carrier 32 is not limited here, and the designer can reasonably design according to actual needs; for example, the first carrier 32 can be but is not limited to a plate structure or a frame structure. The specific connection mode between the first carrier 32 and the driving end of the first conveying mechanism 31 is not limited here, and the designer can reasonably design according to actual needs; for example, the first carrier 32 can be but is not limited to detachably connected with the driving end of the first conveying mechanism 31 by at least one of screwing, clamping or inserting; for another example, the first carrier 32 can also be but is not limited to non-detachably connected with the driving end of the first conveying mechanism 31 by welding or riveting.

[0060] The first clamping mechanism 33 is one of the clamping mechanisms of the first feeding and discharging module 30, and the specific structure of the first clamping mechanism 33 will be described below.

[0061] The second clamping mechanism 34 is another clamping mechanism of the first feeding and discharging module 30. The specific structure of the second clamping mechanism 34 will be described below.

[0062] The operator stands in front of the operation table 14 and places the product to be processed on the jig 13. The conveying line 12 moves the jig 13 to a suitable position. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move so as to move the first clamping mechanism 33 to the top of the jig 13. At this time, the first clamping mechanism 33 can grab the product to be processed from the jig 13. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move so as to move the second clamping mechanism 34 to the top of the pad printing table 21. At this time, the second clamping mechanism 34 can grab the product with one-side pad printing completed from the pad printing table 21. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move so as to move the first clamping mechanism 33 to the top of the pad printing table 21. At this time, the first clamping mechanism 33 can place the product to be processed on the pad printing table 21 (the pad printing machine body 22 of the first pad printing module 20 can perform pad printing processing on the first surface of the product to be processed). Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move so as to move the second clamping mechanism 34 to the top of the jig 13. At this time, the second clamping mechanism 34 can place the product with one-side pad printing completed on the empty jig 13. In this way, the batch production is realized through the circulation.

[0063] Specifically, as shown in Figures 5-7 At least one of the first clamping mechanism 33 and the second clamping mechanism 34 includes a first driving member 351 and a first grabbing member 352. The first driving member 351 is installed on the first carrier 32. The first grabbing member 352 is installed on the driving end of the first driving member 351. The driving end of the first driving member 351 can move downward along the Z-axis direction to drive the first grabbing member 352 to move downward along the Z-axis direction to the first preset taking and placing position. In the first preset taking and placing position, the first grabbing member 352 is configured to grab the product to be processed from the jig 13, place the product to be processed on the pad printing table 21, and / or in the first preset taking and placing position, the first grabbing member 352 is configured to grab the product with one-side pad printing completed from the pad printing table 21, and place the product with one-side pad printing completed on the empty jig 13.

[0064] The first driving member 351 is a power source of the first clamping mechanism 33 and / or the second clamping mechanism 34, and is used to drive the first grabbing member 352 to move along the Z-axis direction. Here, the specific form of the first driving member 351 is not limited, and the designer can reasonably design according to the actual needs. For example, the first driving member 351 can include but is not limited to a pneumatic cylinder or a linear motor.

[0065] The first driving member 351 is installed on the first bearing member 32. The specific connection mode between the first driving member 351 and the first bearing member 32 is not limited here, and a designer can reasonably design according to actual needs; for example, the first driving member 351 can be, but is not limited to, detachably connected with the first bearing member 32 in at least one of screwing, clamping or inserting; for another example, the first driving member 351 can also be, but is not limited to, fixedly connected with the first bearing member 32 by riveting.

[0066] The first grab 352 is a clamping mechanism of the first clamping mechanism 33 and / or the second clamping mechanism 34, and the first grab 352 is an electric grab.

[0067] The first grab 352 is installed on the driving end of the first driving member 351. The specific connection mode between the first grab 352 and the driving end of the first driving member 351 is not limited here, and a designer can reasonably design according to actual needs; for example, when the first driving member 351 includes a pneumatic cylinder, the telescopic rod of the pneumatic cylinder is connected with the first grab 352 as the driving end, and the first grab 352 can be fixedly connected with the telescopic rod of the pneumatic cylinder by the mounting bracket 353 through screwing; for another example, when the first driving member 351 includes a linear motor, the mover of the linear motor is connected with the first grab 352 as the driving end, and the first grab 352 can be fixedly connected with the mover of the linear motor by the mounting bracket 353 through screwing.

[0068] The operator stands in front of the operation table 14 and places the product to be processed on the jig 13. The conveying line 12 moves the jig 13 to the appropriate position. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move the first clamping mechanism 33 to the position directly above the jig 13. At this time, the driving end of the first driving part 351 of the first clamping mechanism 33 moves downward along the Z-axis direction to drive the first gripper 352 to move downward along the Z-axis direction to the first preset picking and placing position. The first gripper 352 can pick the product to be processed from the jig 13. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move the second clamping mechanism 34 to the position directly above the pad printing table 21. At this time, the driving end of the first driving part 351 of the second clamping mechanism 34 moves downward along the Z-axis direction to drive the first gripper 352 to move downward along the Z-axis direction to the first preset picking and placing position. The first gripper 352 can pick the product with one side pad printing completed from the pad printing table 21. Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move the first clamping mechanism 33 to the position directly above the pad printing table 21. At this time, the driving end of the first driving part 351 of the first clamping mechanism 33 moves downward along the Z-axis direction to drive the first gripper 352 to move downward along the Z-axis direction to the first preset picking and placing position. The first gripper 352 can place the product to be processed on the pad printing table 21 (the pad printing machine body 22 of the first pad printing module 20 can perform pad printing processing on the first surface of the product to be processed). Then the driving end of the first conveying mechanism 31 drives the first carrier 32 to move the second clamping mechanism 34 to the position directly above the jig 13. At this time, the driving end of the first driving part 351 of the second clamping mechanism 34 moves downward along the Z-axis direction to drive the first gripper 352 to move downward along the Z-axis direction to the first preset picking and placing position. The first gripper 352 can place the product with one side pad printing completed on the empty jig 13. This cycle is repeated to realize batch production.

[0069] It should be noted that after the first gripping mechanism 33 completes the operation of picking up the product to be processed from the jig 13 and placing the product to be processed on the pad 21 at the first preset picking and placing position, the driving end of the first driving member 351 of the first gripping mechanism 33 moves upward along the Z-axis direction to drive the first gripping mechanism 33 to move to a suitable position along the Z-axis direction, so as to effectively avoid the interference between the product to be processed and other components during the movement of the driving end of the first conveying mechanism 31 driving the first bearing member 32. Similarly, after the first gripping mechanism 352 of the second gripping mechanism 34 completes the operation of picking up the product on which one-side pad printing is completed from the pad 21 and placing the product on which one-side pad printing is completed on the empty jig 13 at the first preset picking and placing position, the driving end of the first driving member 351 of the second gripping mechanism 34 also moves upward along the Z-axis direction to drive the first gripping mechanism 352 of the second gripping mechanism 34 to move upward along the Z-axis direction to a suitable position, so as to effectively avoid the interference between the product on which one-side pad printing is completed and other components during the movement of the driving end of the first conveying mechanism 31 driving the first bearing member 32.

[0070] As shown in Figures 5-7 , the first conveying mechanism 31 comprises a first conveying unit 311 and a second conveying unit 312; the first conveying unit 311 is installed on the support 11, the second conveying unit 312 is installed on the driving end of the first conveying unit 311, and the first bearing member 32 is installed on the driving end of the second conveying unit 312; the driving end of the first conveying unit 311 moves along the Y-axis direction, and the driving end of the second conveying unit 312 moves along the Z-axis direction.

[0071] The movement of the first bearing member 32 is driven by the movement of the driving end of the first conveying unit 311 along the Y-axis direction and the movement of the driving end of the second conveying unit 312 along the Z-axis direction, so as to move the first gripping mechanism 33 to the upper side of the jig 13 or move the first gripping mechanism 33 to the upper side of the pad 21, thereby facilitating the loading and unloading operation of the product to be processed; the movement of the first bearing member 32 is driven by the movement of the driving end of the first conveying unit 311 along the Y-axis direction and the movement of the driving end of the second conveying unit 312 along the Z-axis direction, so as to move the second gripping mechanism 34 to the upper side of the pad 21 or move the second gripping mechanism 34 to the upper side of the empty jig 13, thereby facilitating the loading and unloading operation of the product on which one-side pad printing is completed.

[0072] Specifically, as shown in Figures 5-7As shown, the first conveying unit 311 comprises a cross beam 3111 and a first linear motor 3112, the cross beam 3111 is arranged across the support 11 along the Y-axis direction, and the first linear motor 3112 is installed on the cross beam 3111.

The first pad printing module 20 further comprises a pad printing machine body 22 and a second conveying mechanism 23; the pad printing table 21 is connected with the pad printing machine body 22 via the second conveying mechanism 23, the second conveying mechanism 23 is configured to drive the pad printing table 21 to move along the X-axis direction, so as to switch the pad printing table 21 between the first position and the second position; in the first position, the pad printing machine body 22 performs pad printing processing on the first surface of the product to be processed carried on the pad printing table 21; in the second position, the second clamping mechanism 34 grabs the product with one-side pad printing completed from the pad printing table 21, and the first clamping mechanism 33 places the product to be processed on the pad printing table 21.

[0074] By designing the second conveying mechanism 23, the second conveying mechanism 23 drives the pad printing table 21 to move along the X-axis direction, so as to switch the pad printing table 21 between the first position and the second position, so as to provide sufficient operation space for the second clamping mechanism 34 to grab the product with one-side pad printing completed from the pad printing table 21, and provide sufficient operation space for the first clamping mechanism 33 to place the product to be processed on the pad printing table 21.

[0075] Specifically, as shown in the drawings, Figures 5-7 The second conveying mechanism 23 comprises a conveying track 231 and a second driving member 232; the conveying track 231 is installed on the pad printing machine body 22 and extends along the X-axis direction, and the pad printing table 21 is slidably connected with the conveying track 231; the second driving member 232 is installed on the pad printing machine body 22, and the driving end of the second driving member 232 is fixedly connected with the pad printing table 21. The second driving member 232 can drive the pad printing table 21 to move along the X-axis direction relative to the conveying track 231, so as to switch the pad printing table 21 between the first position and the second position.

[0076] The conveying track 231 is a sliding rail of the second conveying mechanism 23. The specific connection mode between the conveying track 231 and the pad printer body 22 is not limited here, and a designer can reasonably design according to actual needs. For example, the conveying track 231 can be, but is not limited to, detachably connected with the pad printer body 22 by at least one of the following modes such as screwing, clamping or inserting. For another example, the conveying track 231 can also be, but is not limited to, fixedly connected with the pad printer body 22 by riveting.

[0077] The second driving member 232 is a power source of the second conveying mechanism 23, and is used to drive the pad printing table 21 to move along the X-axis direction relative to the conveying track 231. The specific form of the second driving member 232 is not limited here, and a designer can reasonably design according to actual needs. For example, the second driving member 232 can include a pneumatic cylinder, the telescopic rod of the pneumatic cylinder is fixedly connected with the pad printing table 21 as a driving end, and the telescopic rod of the pneumatic cylinder drives the pad printing table 21 to move along the X-axis direction relative to the conveying track 231 by telescopic motion. For another example, the second driving member 232 can also include a linear motor, the mover of the linear motor is fixedly connected with the pad printing table 21 as a driving end, and the mover of the linear motor drives the pad printing table 21 to move along the X-axis direction relative to the conveying track 231 by reciprocating motion. The specific connection mode between the pad printing table 21 and the driving end of the second driving member 232 is not limited here, and a designer can reasonably design according to actual needs. For example, the pad printing table 21 can be, but is not limited to, detachably connected with the driving end of the second driving member 232 by at least one of the following modes such as screwing, clamping or inserting. For another example, the pad printing table 21 can also be, but is not limited to, fixedly connected with the driving end of the second driving member 232 by riveting.

[0078] By designing the second driving member 232 and the conveying track 231, the second driving member 232 can drive the pad printing table 21 to move along the X-axis direction relative to the conveying track 231 to the first position, so that the pad printer body 22 can perform pad printing processing on the first surface of the product to be processed carried on the pad printing table 21. The second driving member 232 can drive the pad printing table 21 to move along the X-axis direction relative to the conveying track 231 to the second position, so that the second clamping mechanism 34 can grab the product with one side of the pad printing completed from the pad printing table 21, and the first clamping mechanism 33 can place the product to be processed on the pad printing table 21. In this way, the effective replacement between the product with one side of the pad printing completed and the product to be processed is realized, and batch processing is realized.

[0079] As Figure 4 , Figures 8-10As shown, the pad printing system 1 further comprises a baking module 40, a turnover module 50, a second pad printing module 60 and a second feeding and discharging module 70; the baking module 40 has a baking area, and the part of the conveying line 12 downstream of the first feeding and discharging module 30 is arranged in the baking area; the turnover module 50 is installed on the support 11, and the turnover module 50 is located downstream of the baking module 40; the turnover mechanism is configured to pick up the single-side pad printing completed product after baking from the jig 13, and place the single-side pad printing completed product after baking on the jig 13 again after turning over by a preset angle; the second pad printing module 60 is configured to perform pad printing processing on the second surface of the single-side pad printing completed product after turning over; the second feeding and discharging module 70 is installed on the support 11, and the second feeding and discharging module 70 is configured to transfer the single-side pad printing completed product after turning over from the jig 13 to the second pad printing module 60, and transfer the double-side pad printing completed product from the second pad printing module 60 to the discharging end.

[0080] By designing the baking module 40, when the single-side pad printing completed product carried on the jig 13 flows through the baking area of the baking module 40 under the action of the conveying line 12, the baking module 40 can effectively bake the single-side pad printing completed product to avoid the pattern printed on the single-side pad printing completed product sticking to the jig 13 after being turned over by the turnover module 50. By designing the turnover module 50, the turnover module 50 can pick up the single-side pad printing completed product after baking from the jig 13, and place the single-side pad printing completed product after baking on the jig 13 again after turning over by a preset angle, replacing manual turning over with mechanical automatic operation, which is efficient and can reduce labor costs. By designing the second feeding and discharging module 70 and the second pad printing module 60, the conveying line 12 transfers the jig 13 carrying the single-side pad printing completed product after baking to a suitable position, at which time the second feeding and discharging module 70 transfers the single-side pad printing completed product after baking from the jig 13 to the second pad printing module 60, the second pad printing module 60 performs pad printing processing on the second surface of the single-side pad printing completed product after baking, and after the pad printing processing on the second surface of the single-side pad printing completed product after baking is completed, the second feeding and discharging module 70 transfers the double-side pad printing completed product from the second pad printing module 60 to the discharging end; in this way, the second feeding and discharging module 70 replaces manual operation to realize the feeding operation of the single-side pad printing completed product after baking between the jig 13 and the second pad printing module 60, and realize the discharging operation of the double-side pad printing completed product between the second pad printing module 60 and the discharging end.
