Detailed Description
The following description of the embodiments of the present invention will be made more clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Furthermore, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.
The material of the sheet material belt described herein may be a thin metal sheet material belt (such as copper, nickel, silver, gold, etc.), or a thermoplastic polymer such as plastic, but is not limited thereto. Each sheet material strip has a plurality of connected workpieces, with adjacent two workpieces being identical in shape and size.
In view of the technical drawbacks of the related art, the present embodiment provides a sheet material tape splicing method and a sheet material tape splicing apparatus that can perform the sheet material tape splicing method. The sheet material belt splicing equipment is provided with a receiving rail, a feeding mechanism, a welding mechanism, a station to be processed and a control unit. The method of splicing the sheet material web performed when the sheet material web splicing apparatus is operated is controlled by a control unit of the sheet material web splicing apparatus. Of course, certain links in the operation of the sheet material web splicing apparatus may also be manually operated. The control processes hereinafter are performed by the control unit of the sheet-material-belt splicing apparatus for the sake of easy understanding. It will be appreciated that when a certain process is performed, the control unit will also control the mechanical device corresponding to the process.
Fig. 1 shows a flow of a method for splicing a sheet material tape according to the present embodiment, and it should be noted that the method for splicing a sheet material tape according to the present embodiment is applicable when the sheet material tape splicing apparatus of the present embodiment continues to perform feeding of a next batch of sheet material tape after feeding of a first batch of sheet material tape is completed.
The method for splicing the thin sheet material belts in the embodiment comprises the following steps:
step S101, positioning a first sheet material belt in a receiving track. Illustratively, to perform this step, after the nth batch of sheet material strips completely leaves the feeding mechanism after the sheet material strip splicing apparatus is started, the control unit controls the processing waiting position to suspend processing, so that the nth batch of sheet material strips is not pulled by the processing waiting position and is thus retained on the receiving rail. Alternatively, the position of the nth batch of sheet material strips may be determined by clamping the nth batch of sheet material strips by a specially configured clamping hand and making the nth batch of sheet material strips and the receiving track relatively stationary.
Step S102, the second sheet material belt is moved into the material receiving track, and the second sheet material belt is controlled to move, so that a preset overlapping area is formed between the workpiece of the first sheet material belt and the workpiece of the second sheet material belt. When the step is executed, the control unit controls the feeding mechanism to connect the n+1th batch of sheet material belts into the material receiving track and continuously push the n+1th batch of sheet material belts, so that the n+1th batch of sheet material belts and the n+1th batch of sheet material belts are subjected to relative displacement, and a preset overlapping area is formed between the workpiece of the n batch of sheet material belts and the workpiece of the n+1th batch of sheet material belts.
Step S103, welding a preset overlapping area. When a preset overlapping area is formed between the workpiece of the nth batch of sheet material belts and the workpiece of the n+1th batch of sheet material belts, the control unit controls the feeding mechanism to stop pushing the n+1th batch of sheet material belts, so that the current preset overlapping area is maintained between the workpiece of the nth batch of sheet material belts and the workpiece of the n+1th batch of sheet material belts. And then the control unit continuously controls the welding mechanism to weld the workpiece of the nth batch of sheet material belts and the workpiece of the n+1th batch of sheet material belts in the preset overlapping area, so that the nth batch of sheet material belts and the n+1th batch of sheet material belts are connected with each other.
The method for splicing the sheet material belts can automatically weld the tail end of the front sheet material belt and the head end of the rear sheet material belt, so that when the front sheet material belt is pulled by processing equipment in a to-be-processed position, the rear sheet material belt is driven, and the head end of the replaced sheet material belt is not required to be pulled to the to-be-processed position manually, thereby facilitating the splicing operation of the sheet material belts.
In some embodiments, the controlling the movement of the second sheet material strip of step S102 to form a predetermined overlap region between the workpiece of the first sheet material strip and the workpiece of the second sheet material strip includes:
the relative displacement between the first sheet material strip and the second sheet material strip is monitored by CCD visual positioning. Wherein, set up the locating hole on every work piece of thin slice material area, a work piece corresponds a locating hole, therefore when the relative displacement between the thin slice material area of adjacent batch (nth batch and n+1th batch), the locating hole of a thin slice material area work piece is sheltered from by other parts of another thin slice material area work piece to be difficult for observing. When two workpieces of adjacent batches of sheet material belts are completely overlapped, the positioning holes of one sheet material belt workpiece and the positioning holes of the other sheet material belt workpiece are mutually aligned, so that the hollowed-out areas of the positioning holes are easily observed, and when the mutual alignment of the positioning holes of the workpieces of different sheet material belts is monitored, the complete overlapping of the workpieces of different sheet material belts can be determined, and a preset overlapping area is formed.
For example, the preset overlap area may be determined according to the processing type of the to-be-processed bit, for example: when the workpiece is subjected to electroplating treatment, only the sheet material strips are required to pass through the electroplating tank, so that the pulling force on the sheet material strips is weak, and the welding area between the sheet material strips in adjacent batches is not required to be excessively large. For example, when the processing type of the processing station is electroplating, only one workpiece is overlapped and welded in the adjacent batch of sheet material bands, the previous batch of sheet material bands and the next batch of sheet material bands can be simultaneously driven under the pulling of the processing station. Therefore, when the CCD visual positioning monitors that the pair of positioning holes of the workpieces of different sheet material belts are mutually aligned, the preset overlapping area is formed between the workpieces of the sheet material belts.
Of course, the number of the overlapped welded workpieces can be multiple according to actual needs. Another example is: when the processing type of the processing position is the imprinting, two pairs of workpieces are required to be welded, and therefore when the CCD visual positioning monitors that the two pairs of positioning holes of the workpieces of different sheet material belts are mutually aligned, the preset overlapping area is formed between the workpieces of the sheet material belts.
In some embodiments, in the process of executing step S103, the control unit controls the clamping arm of the welding mechanism to clamp the workpiece of the nth batch of sheet material strips and the workpiece of the n+1th batch of sheet material strips forming the preset overlapping area, so as to press the two workpieces to tightly fit the two workpieces, and reduce the gap between the two workpieces. And then the laser welder welds the two workpieces under the control of the control unit, so that the connection between the adjacent batches of sheet material belts is completed.
In some embodiments, before forming the predetermined overlap region between the workpiece of the first sheet material strip and the workpiece of the second sheet material strip, further comprising:
the workpiece on the end side of the previous batch of sheet material strips and/or the workpiece on the head end side of the next batch of sheet material strips in the adjacent batches of sheet material strips are sheared. Because the ends of some sheet strips are folded and deformed during transportation, etc., trimming is required to make the weld of the predetermined overlap area formed between two adjacent batches of sheet strips more orderly and complete. According to practical situations, the cutting object may be a workpiece at the end side of a previous batch of sheet material strips in the adjacent batch of sheet material strips, or may be a workpiece at the end side of a subsequent batch of sheet material strips. The number of the workpieces to be sheared off is determined according to the actual situation, and is not limited herein. The shearing tool for shearing may be pneumatic scissors, but is not limited thereto.
In some embodiments, as shown in fig. 2, after step S103, further includes:
and step S104, conveying the welded sheet material belt to a to-be-processed position to process the workpiece. And after the adjacent batches of sheet material belts are welded and connected, the control unit restarts the to-be-processed position to pull the nth batch of sheet material belts, and processes the workpieces of the nth batch of sheet material belts. At this time, the n+1-th lot of sheet material tape is pulled toward the processing station along with the n-th lot of sheet material tape. In the process, the feeding mechanism can provide driving force for the n+1th batch of sheet material belts and can also be in a stop state.
Step S105, coiling the processed sheet material belt to form a tray. The sheet material strips processed by the processing position to be processed are coiled to form the material tray under the action of the material receiving mechanism, and as a plurality of processed sheet material strips are coiled in the coiling process, the material receiving efficiency is improved, and the storage space of the material receiving tray is saved.
It will be understood that, after the control unit detects that the n+1 batch of sheet material strips completely leaves the feeding mechanism, the control unit will at least execute the processes of step S101 to step S103 again, that is, position the n+1 batch of sheet material strips in the receiving track, then move the n+2 batch of sheet material strips into the receiving track, and control the n+2 batch of sheet material strips to move, so that a preset overlapping area is formed between the workpiece of the n+1 batch of sheet material strips and the workpiece of the n+2 batch of sheet material strips, and finally weld the preset overlapping area, so that the control unit repeatedly executes the splicing method of the sheet material strips according to the embodiment according to the input instruction.
In some embodiments, a sheet material tape splicing apparatus is also provided, as shown in fig. 3, and the sheet material tape splicing apparatus of this embodiment includes a feeding mechanism 200, a receiving rail 100, a welding mechanism 300, and a station to be processed (not shown). Illustratively, the loading mechanism 200 of the present embodiment is a tray loading mechanism 200, which is typically used for feeding a sheet material onto a tray.
The feeding mechanism 200 is used to feed a sheet material strip into the receiving track 100, and if the sheet material strip is fed for the nth batch, the sheet material strip needs to be pulled along the receiving track 100 by a person or a corresponding device into a position to be processed (not shown in the figure).
In this embodiment, the receiving track 100 is used to guide the movement of the sheet material strips, and continues to support the batch of sheet material strips F1 when the batch is completely disengaged from the feeding mechanism 200 and is not pulled by the station to be processed. At this time, when the sheet material band F2 of the next batch is fed into the feeding track 100 through the feeding mechanism 200, the sheet material band F1 of the previous batch is relatively moved by the pushing of the feeding mechanism 200, so that a predetermined overlapping area a is formed between the workpiece B of the sheet material band F1 of the previous batch and the workpiece B of the sheet material band F2 of the next batch. It should be noted that, when the sheet material tape F2 of the subsequent batch is fed into the receiving rail 100, the to-be-processed position should stop pulling the sheet material tape, so that a predetermined overlap area a can be formed between the workpiece B of the sheet material tape F1 of the previous batch and the workpiece B of the sheet material tape F2 of the subsequent batch.
At this time, the welding mechanism 300 welds the preset overlapping area a formed between the workpiece B of the previous batch of sheet material tape F1 and the workpiece B of the next batch of sheet material tape F2, so that the workpieces B of two adjacent batches of sheet material tapes are connected to each other, and the previous batch of sheet material tape F1 is driven to the next batch of sheet material tape F2 when being pulled by the processing equipment at the processing position.
That is, when the receiving rail 100 retains the nth batch of sheet material tapes, the feeding mechanism 200 inserts the (n+1) th batch of sheet material tapes into the receiving rail 100 so that a predetermined overlap area a is formed between the workpieces B of the adjacent batches of sheet material tapes. The welding mechanism 300 welds the preset overlapping area a formed between the workpieces B of the adjacent batches of sheet material strips, so that the adjacent batches of sheet material strips are connected into a whole, and pulled by the processing equipment at the position to be processed, thereby avoiding manually pulling the head end of the replaced sheet material strip to the position to be processed and improving the working efficiency.
With continued reference to fig. 3, the sheet material web splicing apparatus further includes a CCD camera 400. The CCD camera 400 is used to monitor the movement of the next batch of sheet material strip F2 to form the predetermined overlap area A.
When the CCD camera 400 detects that the preset overlap area a is formed, the feeding mechanism 200 is stopped to continue pushing the sheet material strips, so that the sheet material strip F2 of the next batch and the sheet material strip F1 of the previous batch are no longer relatively moved, thereby maintaining the preset overlap area a in a desired state, and then the welding mechanism 300 welds the preset overlap area a, thereby completing the interconnection between two sheet material strips of the adjacent batches.
With continued reference to fig. 3, in some embodiments, in order to reduce the occurrence of wobble in the sheet material band F1 of the previous batch during the formation of the predetermined overlap area a between two sheet material bands of adjacent batches, a first gripper (not shown) is provided on the receiving track 100, and the first gripper grips the sheet material band F1 of the previous batch to maintain a stable state when the predetermined overlap area a is formed between two sheet material bands of adjacent batches. After a predetermined overlap area a is formed between two adjacent batches of sheet material strips and the welding operation of the welding mechanism 300 is completed, the first gripper releases the previous batch of sheet material strip F1.
With continued reference to FIG. 3, in some embodiments, to enhance the welding effect, the welding mechanism 300 includes a second clamp and a laser welder (not shown). When the laser welder welds the preset overlapping area A, the second clamping hand clamps the preset overlapping area A, so that two thin sheet material strips forming the preset overlapping area A are tightly attached. When the welding is completed, the second clamping hand releases the preset overlapping area A, so that the two fused sheet material bands connected integrally can be moved. When a laser welder is used, a meltable sheet material strip is taken as an example of copper material: the power of the laser welding process should be between 50W and 80W, and the processing speed should be between 50mm and 100mm/s.
With continued reference to fig. 4, in some embodiments, to enable the meltable sheet material strip to move stably in the receiving rail 100, the receiving rail 100 of this embodiment includes a rail body 110 and a baffle 130. The rail body 110 is provided with a sliding groove 120 extending along the length direction of the rail body 110, and two end surfaces of the rail body 110 are respectively provided with an input port and an output port which are communicated with the sliding groove 120 and are respectively used for inputting and outputting a sheet material belt. The baffle 130 is located at an edge of the chute 120 and is formed to extend along a length direction of the rail body 110. The strip of meltable sheet material is restrained from rocking by the stop 130 as it moves in the receiving track 100.
With continued reference to fig. 3, in some embodiments, to provide a more orderly and complete weld of the predetermined overlap area a formed between two sheets of adjacent batches, the sheet-material-strip splicing apparatus of the present embodiment further includes a shearing mechanism 500 positioned between the loading mechanism 200 and the receiving track 100. In actual production, the end morphology of the sheet material strip, such as copper, may not be uniform and therefore requires trimming. The form of the predetermined overlap area a formed between two adjacent batches of sheet material strips is more complete by shearing the sheet material strips by the shearing mechanism 500. Illustratively, the shearing mechanism 500 of the present embodiment includes a pneumatic shears 510 and a lifting assembly 520. The pneumatic shears 510 are used to shear a strip of sheet material so that burrs are not produced on the shearing face. The lifting assembly 520 is used to adjust the position of the pneumatic shears 510 such that the pneumatic shears 510 are closer to or farther away from the sheet material web.
In this embodiment, the processing device in the station to be processed may be one of a gold plating device, an etching device, a polishing device, an imprinting device, and a coloring device, but is not limited thereto. The processing apparatus of this embodiment may further include a material receiving mechanism for coiling the sheet material strip processed by the processing device, so as to facilitate the material receiving work of the sheet material strip processed into a semi-finished product.
The above description of the preferred embodiments of the present invention should not be taken as limiting the scope of the invention, but rather should be understood to cover all modifications, variations and adaptations of the present invention using its general principles and the following detailed description and the accompanying drawings, or the direct/indirect application of the present invention to other relevant arts and technologies.
