Description

Technical Field

[0001] The invention relates to a non-contact smart card manufacturing device, in particular to a plate material positioning and conveying device. Background Art

[0002] With the development of contactless smart card technology, the production and processing requirements for smart cards are getting higher and higher. In the manufacturing process of contactless smart cards, first a rectangular coil is wound on the sheet, then the chip is welded to the antenna of the coil and packaged, and finally another layer of sheet is covered on the packaged layer to ensure that the coil and chip are not exposed. Usually, in the manufacturing process of contactless energy cards, the premise is that the placement accuracy must be accurate during the handling and transportation of the sheet, otherwise it will affect a series of subsequent problems, such as reducing the winding coil accuracy, the composite welding processing accuracy, and the repeated bonding accuracy between the sheets, which ultimately leads to a high scrap rate.

[0003] Since the smart card production sheets and cover sheets have the characteristics of large area, thin thickness, good softness and easy damage, it is very difficult to position and transport the smart card production sheets or cover sheets, and it is easy to cause inaccurate positioning, reducing the accuracy of subsequent composite welding processing. At the same time, the sheets are easily damaged during the transportation process, reducing the product yield. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned problems and provide a sheet positioning and handling device, which is used to accurately position the sheet material used as raw material during the handling process before the processing and manufacturing of smart cards, so that the sheet material can be accurately positioned at the two workstations before and after the handling, thereby improving the product yield.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A sheet material positioning and transporting device comprises a frame, a sheet material transporting mechanism arranged on the frame, and a transverse driving mechanism for driving the sheet material transporting mechanism to reciprocate between a front station and a rear station of the sheet material transporting; wherein:

[0007] The sheet material handling mechanism includes a mounting frame, a suction cup assembly arranged on the mounting frame, at least two groups of positioning assemblies and a vertical power mechanism for driving the suction cup assembly and the positioning assembly to perform vertical movement; the suction cup assembly includes a plurality of suction cups for sucking the sheet material, and the positioning assembly includes a positioning member for positioning the positioning hole portion of the sheet material; the positioning member is provided with an avoidance groove for avoiding the positioning pin on the sheet material placement table that passes through the positioning hole, and the bottom surface of the positioning member is also provided with suction holes for sucking the surrounding portion of the positioning hole of the sheet material.

[0008] The working principle of the above-mentioned sheet material positioning and handling device is:

[0009] In the process of sheet material handling, the sheets are first stacked on the sheet material placement table, which is arranged below the sheet material handling mechanism. The positioning pins on the sheet material placement table are installed on the sheet material placement table and extend out of the table surface of the sheet material placement table, wherein the positioning pins on the sheet material placement table correspond to the positioning holes on the sheets one by one. Before the sheets are handled, the sheets are first stacked on the sheet material placement table, and the positioning pins on the sheet material placement table are forced to pass through the positioning holes on the sheets, thereby completing the precise positioning of the sheets before handling. In the process of stacking sheets, it is necessary to ensure that the height of the stacked sheets is lower than the height of the positioning pins. After the stacking is completed, the lateral driving mechanism then drives the sheet material transporting mechanism to move to the position above the sheet material placement table corresponding to the sheet material. At this time, the position of the positioning piece on the sheet material transporting mechanism is located directly above the positioning pin on the sheet material placement table and the positioning hole of the sheet material, and the positions correspond to each other. Driven by the vertical power mechanism, the suction cup assembly and the positioning assembly move downward at the same time and contact the surface of the sheet material. The avoidance groove of the positioning piece avoids the positioning pin on the sheet material placement table, and the bottom surface of the positioning piece presses against the surrounding part of the positioning hole of the sheet material, and the suction hole absorbs the surrounding part of the positioning hole on the sheet material, tensioning the sheet material around the positioning hole, pressing the sheet material, and under the action of the two positioning pieces, the position of the sheet material is accurately fixed, and then the suction cup absorbs the sheet material, and the vertical power mechanism drives the suction cup and the positioning piece that absorb the sheet material upward again. Movement, through the lateral drive of the lateral drive mechanism, the sheet is transported to the workbench for making smart cards, and the workbench is provided with positioning pins corresponding to the positioning holes on the sheet. When the sheet moves to the corresponding positions of the positioning holes on the sheet and the positioning pins on the workbench, the sheet moves downward under the drive of the vertical power mechanism, and the suction cup, the positioning piece and the adsorbed sheet move downward at the same time. Under the precise positioning of the positioning piece adsorption, the positioning hole of the sheet is accurately matched with the positioning pin on the workbench, so that the positioning pin on the workbench passes through the positioning hole on the sheet. As the vertical drive mechanism continues to work, the sheet transporting mechanism presses the sheet against the workbench, and finally the suction cup and the positioning piece release the sheet at the same time, thereby realizing the precise transport of the sheet to the workbench, thereby completing the transport of the post-transportation workstation.

[0010] During the process of sheet material transportation, the position of the positioning pin on the sheet material placement table corresponds to the position of the positioning pin on the workbench. By providing positioning holes in the sheet material, the sheet material positioning and transportation device of the present invention uses the positioning holes on the sheet material as the positioning precision during the process of transporting the sheet material. By ensuring that the position of the positioning holes on the sheet material remains unchanged during the transportation process, the positioning holes on the sheet material can cooperate with the positioning pins on the workbench, so that the sheet material can no longer be displaced in the horizontal direction after being placed on the workbench, thereby realizing precise positioning of the sheet material on the workbench.

[0011] Preferably, there are multiple suction holes, which are evenly distributed along the axis of the avoidance groove. The purpose is that when the vertical drive mechanism drives the suction cup assembly and the suction cup assembly to move vertically to transport the sheet material, when the bottom of the positioning member contacts the surface of the sheet material, the suction holes are evenly adsorbed along the portion around the positioning holes of the sheet material, which is conducive to the sheet material located around the suction holes being in a tensioned state under the suction force of the suction holes, so that this part of the sheet material will not be flexibly deformed during the transportation process, and at the same time, the positioning holes in this part will not change their positions due to the flexible deformation of the sheet material, thereby ensuring the accuracy of the position of the positioning holes.

[0012] In a preferred embodiment of the present invention, the plurality of suction cups are arranged in a matrix on the mounting frame, and the mounting frame is provided with an adjustment slot at a position corresponding to each suction cup, and the adjustment slot extends along the direction of the sheet material transportation. A plurality of suction cups are provided and arranged evenly, so as to be more conducive to adsorbing the sheet material. Since the mounting plate is provided with an adjustment slot at a position corresponding to each suction cup, the position of the adjacent suction cups can be adjusted to adapt to the transportation of sheets of different sizes.

The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said bolt has a round shank to contact with said linking rod. By setting the above structure, it is not only conducive to the positioning member to operate more stably during the plate positioning process, but also conducive to better making the bottom surface of the positioning member close to the plate, thereby improving the positioning accuracy, and the elastic element can play a buffering role during the contact between the positioning member and the plate, thereby preventing the positioning member from being overly pressurized and damaging the plate. Among them, a sliding mechanism can also be set between the positioning member and the mounting frame to guide the vertical movement of the positioning member, and the sliding mechanism can be a slider rail mechanism or a slide rod mechanism.

[0014] Furthermore, the lower end of the guide slide rod is provided with an avoidance hole for avoiding the positioning pin of the workbench or the sheet material placement table; the avoidance hole and the avoidance groove are located on the same axis. By providing the avoidance hole, interference between the guide slide rod and the positioning pin can be avoided.

[0015] Preferably, the bottom surface of the positioning member is lower than the bottom surface of the suction cup. Its function is that, in the process of lifting the sheet from the sheet placement, since the positioning surface of the positioning member is lower than the bottom surface of the suction cup, the positioning member will first contact the surface of the sheet, and the suction hole of the positioning member will absorb the part of the sheet located around the positioning hole, so that the absorbed part of the sheet is in a tensioned state, so that the two precise positioning points (i.e., the two positioning holes) on the sheet will not move in position due to the flexible deformation of the sheet during the subsequent handling process, thereby ensuring that the positioning holes of the sheet can smoothly pass through the positioning pins on the workbench, thereby achieving accurate positioning of the sheet. In the process of placing the sheet on the workbench, since the positioning surface of the positioning piece is lower than the bottom surface of the suction cup, the positioning piece will first contact the positioning pin in the workbench, so that the positioning pin on the workbench passes through the positioning hole on the sheet, so that the positions of the two positioning holes on the sheet are determined, and thus the position of the entire sheet is also determined. In the subsequent process of the suction cup placing the sheet on the workbench, since the two positioning holes on the sheet have been accurately positioned, the entire sheet will no longer be offset, thereby achieving accurate positioning of the sheet on the workbench.

[0016] Preferably, the elastic element is a spring, which is sleeved on the guide rod, one end of which acts on the mounting frame, and the other end of which acts on the positioning slide. The above spring can put the positioning member in a tight state, which is conducive to better pressing the positioning member against the sheet material during the positioning and transportation process, improving the positioning accuracy, and playing a buffering role in the soft contact process between the positioning member and the sheet material, ensuring that the sheet material is not damaged.

[0017] Preferably, the vertical power mechanism includes a vertical fixed seat, a vertical motor arranged on the vertical fixed seat, a screw transmission mechanism and a synchronous transmission mechanism for transmitting the power of the vertical motor to the screw transmission mechanism, wherein the screw transmission mechanism is composed of multiple groups, and the multiple groups of screw transmission mechanisms are distributed around the mounting frame; each group of screw transmission mechanisms includes a screw and a screw nut cooperating with the screw, one end of the screw is fixed on the mounting frame, and the other end extends vertically upward; the screw nut is rotatably connected to the vertical fixed seat; the synchronous transmission mechanism includes a first active driving wheel, a first driven driving wheel and a first transmission belt, wherein the first active driving wheel is arranged on the main shaft of the vertical motor, the first driven driving wheel is multiple, and are respectively arranged on the screw nut of each group of screw transmission mechanisms, and rotate synchronously with the screw nut, and the first transmission belt is sequentially wrapped around the first active driving wheel and multiple first driven driving wheels. By adopting the above structure, the upward and downward movement of the suction cup assembly and the positioning assembly can be realized through the vertical power mechanism; the specific process is: first, the vertical motor drives the first active driving wheel to rotate, and drives the first driven driving wheel to rotate through the first transmission belt, thereby driving the screw nut to rotate, and then driving the vertical screw to move upward or downward in a straight line, and finally driving the suction cup assembly and the positioning assembly on the mounting frame to move upward or downward in a straight line. In addition, since the vertical motor drives the first active driving wheel to rotate, the first driven driving wheel on the screw nut of the screw transmission mechanism located around the mounting frame also rotates synchronously, so that the lifting speed of each position on the mounting frame can be kept consistent, so that multiple suction cups installed on the suction cup assembly can contact the sheet material at the same time, so that the sheet material handling is smoother and more accurate.

[0018] Preferably, a tensioning wheel for tensioning the first transmission belt is provided between the first active driving wheel and the first driven driving wheel, and the tensioning wheel is connected to the vertical fixing seat. By designing the tensioning wheel, the transmission efficiency of the first driving belt can be improved.

[0019] Preferably, the transverse drive mechanism includes a transverse motor and a transverse transmission mechanism arranged at one end of the frame, wherein the transverse transmission mechanism includes a second active drive wheel arranged on the frame and connected to the transverse motor, a second driven drive wheel arranged at the other end of the frame, and a second transmission belt connected between the second active drive wheel and the second driven drive wheel; the vertical fixed seat is fixed to one side of the second transmission belt through a fixing assembly. The second active drive wheel is driven to rotate by the transverse motor, thereby driving the second transmission belt between the second active drive wheel and the second driven drive wheel to move, thereby driving the fixing assembly to move, so that the vertical fixed seat moves horizontally, and the horizontal movement of the sheet material handling mechanism is realized.

[0020] Preferably, the transverse driving mechanism further comprises a transverse guide assembly disposed between the vertical fixing seat and the frame, wherein the transverse guide assembly comprises a transverse guide rail disposed at the bottom of the frame and a transverse slider disposed on the vertical fixing seat and matching with the transverse guide rail. By providing the transverse guide assembly, the stability of the transverse slider can be maintained when the transverse slider moves relative to the transverse guide rail, while ensuring the stability of the operation of the sheet material handling mechanism and improving the positioning accuracy. In addition, by providing the transverse guide assembly, it can be used to bear the weight of the sheet material handling mechanism, so that the second transmission belt only needs to drive the sheet material handling mechanism to make a transverse movement, and does not need to bear the weight of the sheet material handling mechanism, which can extend the service life of the second transmission belt.

[0021] Furthermore, the lateral guide components are in two groups and are respectively located on both sides of the conveying direction of the second transmission belt.

[0022] Further, the fixing assembly includes a first clamping piece arranged on the vertical fixing seat and a second clamping piece clamping the second transmission belt on the first clamping piece, wherein the first clamping block or the second clamping block is provided with a groove matched with the synchronous teeth of the second transmission belt. The fixing assembly is clamped and fixed with the second transmission belt, so that the second transmission belt drives the lateral movement of the vertical fixing seat through the fixing assembly.

[0023] Preferably, the vertical fixing seat is also provided with a first detection piece, and the frame is provided with a first photoelectric sensor, wherein there are two first photoelectric sensors, which are respectively located above the sheet material placement table and above the workbench; the first detection piece passes through the first photoelectric sensor along with the movement trajectory of the vertical fixing seat in the horizontal movement. The purpose is that in the process of the horizontal driving mechanism driving the sheet material handling mechanism to make a horizontal movement, when the first photoelectric sensor on the frame detects the first detection piece on the vertical fixing seat, the control system controls the horizontal driving mechanism to stop working, so that the horizontal driving mechanism can accurately drive the sheet material handling mechanism to move above the sheet material placement table and the workbench, thereby improving the handling accuracy.

There are two second photoelectric sensors, which are vertically arranged on the vertical fixed seat; the second detection piece passes through the second photoelectric sensor along the motion trajectory of the vertical movement of the mounting frame.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1.

Correspondingly, the number of positioning pins on the workbench and the sheet placing table and the number of positioning holes on the sheet also correspond one-to-one to the number of the positioning members. By realizing the coordination between the positioning holes on the sheet and the positioning pins on the workbench, the horizontal displacement of the sheet is limited, thereby further improving the positioning accuracy of the sheet.

[0043] See also Figure 6 There are multiple suction holes 5-12, and they are evenly distributed along the axis of the avoidance groove 5-11. The purpose is that when the vertical power mechanism drives the suction cup assembly 4 and the suction cup assembly 4 to make vertical movements to transport the sheet material 7, when the bottom of the positioning member 5-1 contacts the surface of the sheet material 7, the suction holes 5-12 are evenly adsorbed along the surrounding part of the positioning hole 7-1 of the sheet material 7, which is conducive to the sheet material 7 located around the suction hole 5-12 being in a tensioned state under the suction force of the suction hole 5-12, so that the sheet material 7 in this part will not be flexibly deformed during the transportation process, and the positioning hole 7-1 in this part will not change its position due to the flexible deformation of the sheet material 7, thereby ensuring the accuracy of the position of the positioning hole 7-1.

[0055] See also Fig.10The fixing assembly includes a first clamping piece 3-5 disposed on the vertical fixing seat 6-2 and a second clamping piece 3-6 clamping the second transmission belt 3-4 on the first clamping piece 3-5, wherein the first clamping block or the second clamping block is provided with a groove that matches with the synchronous teeth of the second transmission belt 3-4. The fixing assembly is clamped and fixed with the second transmission belt 3-4, so that the belt drives the lateral movement of the vertical fixing seat 6-2 through the fixing assembly.

[0056] See also Figure 1 , the vertical fixed seat 6-2 is also provided with a first detection piece 9, and the frame 1 is provided with a first photoelectric sensor 10, wherein the number of the first photoelectric sensors 10 is two, which are respectively located above the sheet material placement table 13 and above the workbench 15; the first detection piece 9 passes through the first photoelectric sensor 10 along with the movement trajectory of the vertical fixed seat 6-2 in the horizontal movement. The purpose is that in the process of the horizontal driving mechanism 3 driving the sheet material handling mechanism to make a horizontal movement, when the first photoelectric sensor 10 on the frame 1 detects the first detection piece 9 on the vertical fixed seat 6-2, the control system controls the horizontal driving mechanism 3 to stop working, so that the horizontal driving mechanism 3 can accurately drive the sheet material handling mechanism to move to the top of the sheet material placement table 13 and the workbench 15, thereby improving the handling accuracy.

[0057] See also Fig.11 A second photoelectric sensor 12 is also provided on the vertical fixed seat 6-2, and a second detection piece 11 is provided on the mounting frame 2. There are two second photoelectric sensors 12, which are vertically arranged on the vertical fixed seat 6-2; the second detection piece 11 passes through the second photoelectric sensor 12 along the motion trajectory of the vertical movement of the mounting frame 2.

[0058] See also Figure 1-Figure 6 The working principle of the sheet material positioning and handling device of the present invention is:

[0059] During the transportation of sheet material 7, sheet material 7 is first stacked on sheet material placement table 13, which is arranged below the sheet material transportation mechanism, and positioning pins 14 on sheet material placement table 13 are installed on sheet material placement table 13 and extend out of the table surface of sheet material placement table 13, wherein the positioning pins 14 on sheet material placement table 13 correspond to the positioning holes 7-1 on sheet material 7 one by one. Before the transportation of sheet material 7, sheet material 7 is first stacked on sheet material placement table 13, and the positioning pins 14 on sheet material placement table 13 are caused to pass through the positioning holes 7-1 on sheet material 7, thereby completing the precise positioning of sheet material 7 before transportation. During the process of stacking sheet material 7, it is necessary to ensure that the height of the stacked sheet material 7 is lower than the height of the positioning pins 14. After stacking is completed, the lateral driving mechanism 3 then drives the sheet material transporting mechanism to move to a position above the sheet material placement table 13 corresponding to the sheet material 7. At this time, the position of the positioning member 5-1 on the sheet material transporting mechanism is located directly above the positioning pin 14 on the sheet material placement table 13 and the positioning hole 7-1 of the sheet material 7, and the positions correspond to each other. Driven by the vertical power mechanism 6, the suction cup assembly 4 and the positioning assembly 5 move downward at the same time and contact the surface of the sheet material 7. The avoidance groove 5-1 of the positioning member 5-1 1 avoids the positioning pin 14 on the sheet placing table 13, the bottom surface of the positioning member 5-1 presses against the surrounding part of the positioning hole 7-1 of the sheet 7, and the suction hole 5-12 absorbs the surrounding part of the positioning hole 7-1 on the sheet 7, tensioning the sheet 7 around the positioning hole 7-1, pressing the sheet 7, under the action of the two positioning members 5-1, the position of the sheet 7 is accurately fixed, and then the suction cup 4-1 absorbs the sheet 7, and the vertical power mechanism 6 drives the suction cup 4-1 and the positioning member 5-1 that absorb the sheet 7 again The sheet material 7 moves upward and is transported to the workbench 15 for making smart cards through the lateral drive of the lateral drive mechanism 3. The workbench 15 is provided with a positioning pin 14 corresponding to the positioning hole 7-1 on the sheet material 7. When the sheet material 7 moves to the corresponding position of the positioning hole 7-1 on the sheet material 7 and the positioning pin 14 of the workbench 15, the sheet material 7 moves downward under the drive of the vertical power mechanism 6, and the suction cup 4-1, the positioning member 5-1 and the adsorbed sheet material 7 move downward at the same time. Under the precise positioning by the positioning member 5-1, the positioning hole 7-1 of the sheet material 7 is accurately matched with the positioning pin 14 on the workbench 15, so that the positioning pin 14 on the workbench 15 passes through the positioning hole 7-1 on the sheet material 7. As the vertical power mechanism continues to work, the sheet material transporting mechanism presses the sheet material 7 against the workbench 15. Finally, the suction cup 4-1 and the positioning member 5-1 release the sheet material 7 at the same time, thereby realizing the precise transport of the sheet material 7 to the workbench 15, thereby completing the transport of the post-transportation workstation.

[0060] During the transportation of the sheet material 7, the position of the positioning pin 14 on the sheet material placement table 13 corresponds to the position of the positioning pin 14 on the workbench 15. By providing a positioning hole 7-1 in the sheet material 7, the sheet material positioning and transportation device of the present invention uses the positioning hole 7-1 on the sheet material 7 as the positioning precision during the transportation of the sheet material 7. By ensuring that the position of the positioning hole 7-1 on the sheet material 7 remains unchanged during the transportation process, the positioning hole 7-1 on the sheet material 7 can cooperate with the positioning pin 14 on the workbench 15, so that the sheet material 7 can no longer be displaced in the horizontal direction after being placed on the workbench 15, thereby realizing the precise positioning of the sheet material 7 on the workbench 15.

Through the slider rail mechanism, the running stability of the positioning member 5-1 during the positioning process can also be guaranteed, and the bottom surface of the positioning member 5-1 can be better pressed against the sheet material 7, thereby improving the positioning accuracy.
