Description

Technical Field

[0001] The present invention relates to the technical field of fuse processing, and in particular to a fuse processing device and method. Background Art

[0002] During the wire bonding process, the two wire ends of the pin wire need to be staggered up and down first, and then the two pin ends of the pin wire need to be crossed up and down through the staggered bending of the equipment. When the ceramic sheet is assembled with the bent pin wire, the ceramic sheet needs to be horizontally squeezed and inserted between the pin wires that are staggered up and down, and the staggered pin wires clamp and fix the two sides of the ceramic sheet, and the conveying structure conveys the soldering unit for soldering and fixation. Since the ceramic sheet has a certain thickness, when the spacing between the two pin wires that are staggered up and down is too small, the ceramic sheet is easy to be pressed against the upper bent pin wire end during assembly. When pushing the assembly, it is easy to bend the upper pin wire, and it is impossible to accurately assemble and align. When the spacing between the two pin ends that are staggered up and down is too large, the ceramic sheet can be easily assembled between the two staggered pin wire ends, but due to the large staggered spacing, the clamping force between the two pin wire ends becomes loose. When conveying to the soldering unit, the pin wire and the ceramic sheet need to be flipped into a vertical state. When the clamping force becomes loose, the ceramic sheet is easy to fall off under the slight vibration of the machine operation, resulting in assembly failure.

[0003] Therefore, a device and method for processing a fuse are invented. Summary of the invention

[0004] The object of the present invention is to provide a processing device and method for a fuse, so as to solve the above-mentioned problem that when the clamping force becomes loose, the ceramic piece is easy to fall off under the slight vibration of the machine operation, resulting in assembly failure.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a processing device for a fuse, comprising a machine tool and a feeding tape for bonding and fixing a lead wire, an assembly device is arranged on one side of the machine tool, the assembly device is used to assemble the lead wire with a ceramic sheet, the assembly device comprises a pushing device and an assembly mold for assembling the ceramic sheet, a plurality of expansion plates are hinged on the assembly mold, one end of each expansion plate is connected to the assembly mold by a spring, a plurality of flip pressing plates are arranged at the front end of the assembly mold, the flip pressing plates are installed on the assembly mold by a driving member, an upper pressing component connected to the machine tool by a bracket is arranged above the assembly mold, and the upper pressing component comprises a corresponding flip pressing plate The movable pressing block is arranged to be tilted and adjusted by the expansion plate during the pushing process of the ceramic sheet, so as to perform a spread-out assembly on the first and second wire ends of the pin wire, ensuring that each assembled ceramic sheet can be smoothly pushed between the first and second wire ends, effectively preventing the first wire end and the ceramic sheet from being pressed against each other, causing the first wire end to be squeezed and deformed and resulting in assembly failure; the assembled pin wire and ceramic sheet are clamped by the movable pressing block and the flip pressing plate; when the movable pressing block and the flip pressing plate are slightly rotated, the pin wire is slightly twisted to increase the torque between the first and second wire ends, so that the ceramic sheet is clamped more tightly, preventing the ceramic sheet from falling off during the twisting vertical feeding of the feeding tape, resulting in assembly failure.

[0006] Preferably, the assembly equipment also includes a disc loader and a feeding device. The disc loader is arranged on one side of the feeding device and is used for discharging ceramic sheets. Four discharge ports are arranged at the adjacent ends of the disc loader and the feeding device.

The adsorption member includes two rows of adsorption tubes symmetrically arranged for adsorption and feeding of ceramic sheets. The four discharge ports can discharge four ceramic sheets at a time. In conjunction with the assembly mold, four pin lines can be assembled with the ceramic sheets at one time, thereby improving the assembly efficiency. The two rows of adsorption tubes are respectively used for loading eight ceramic sheets in batches. While the front row of adsorption tubes is aligned with the assembly mold for loading, the rear row of adsorption tubes is aligned with the pushing bracket to place the ceramic sheets on the pushing bracket. During reciprocating loading, the front row of adsorption tubes is used to load the ceramic sheets on the pushing bracket into the assembly mold, and the rear row of adsorption tubes loads the ceramic sheets on the discharge port onto the pushing bracket, thereby improving the loading accuracy.

[0007] Preferably, the assembly mold is provided with four limiting feed troughs, and the pushing device includes a pushing bracket, on which are arranged four push rods corresponding to the feed troughs, and a moving platform for driving the pushing bracket to move horizontally is arranged under the pushing bracket. The four limiting feed troughs are used to limit the ceramic sheet. When the push rods push the ceramic sheet to move, the limiting feed troughs ensure that the ceramic sheet moves horizontally, thereby ensuring that the ceramic sheet can be accurately aligned with the pin line, thereby improving the installation quality.

[0008] Preferably, the expansion plate and the spring connection end are tilted upward, and the other end of the expansion plate is in contact with the upper end surface of the assembly mold. The spacing between the expansion plate at the spring end and the assembly mold is greater than the thickness of the ceramic sheet. In the original state, the one end plate surface of the expansion plate is higher than the ceramic sheet, so that the ceramic sheet is always located below the expansion plate. When the ceramic sheet is moved by thrust, the upper end surface of the ceramic sheet contacts the lower end surface of the expansion plate. During continuous movement, the other end of the expansion plate is pushed open. The expansion plate is used to expand the first line end. Since the expansion plate is always located between the first line end and the ceramic sheet when the first line end is assembled, the ceramic sheet is effectively prevented from being against the first line end.

[0009] Preferably, a two-axis movable platform is provided below the assembly mold, an inner groove for accommodating a driving member is provided inside the assembly mold, and the two-axis movable platform is used to drive the assembly mold to move.

When the movable pressure block and the flip pressure plate clamp the pin wire and the ceramic sheet, the movable pressure block can rotate together with the flip pressure plate.

[0012] Preferably, the pin wire has two wire ends, namely a first wire end and a second wire end. The machine tool is provided with a material guide roller group for guiding and flipping the feeding tape. A soldering device is provided on one side of the material guide roller group.

[0014] The present invention provides the following technical solution: a method for using a fuse processing device, comprising the following steps:

[0015] S1: The arc-shaped end of the lead wire is adhered to the feeding tape. When the lead wire is wired, the first wire end and the second wire end are bent toward each other and staggered up and down. The first wire end is staggered at the upper end of the second wire end. The lead wire moves to the assembly mold with the feeding tape to be assembled with the ceramic sheet.

[0016] S2: After the pin line is moved and aligned, the assembly mold moves upward under the drive of the two-axis moving platform, so that the pin line wire end contacts the surface of the assembly mold, and the first wire end is located above one end of the expansion plate;

[0017] S3: The adsorption tube on the feeding device adsorbs the four ceramic sheets onto the four limited feeding troughs on the assembly mold. At this time, the other end of the expansion plate is located above the ceramic sheet. The pushing bracket moves horizontally under the drive of the mobile platform. The four push rods contact the ceramic sheet and push the ceramic sheet along the feeding trough. During the movement of the ceramic sheet, the expansion plate is supported to move the end of the expansion plate and the first line end upward to open the first line end. Under the action of pushing, the ceramic sheet is smoothly pushed between the first line end and the second line end.

[0018] S4: The upper pressing assembly and the movable pressing block are pressed downward to press the movable pressing block and the ceramic sheet, the pushing bracket drives the push rod to reset, and the assembly mold moves in the same direction as the pushing bracket under the drive of the two-axis moving platform, so that the flip pressing plate moves to the position corresponding to the movable pressing block, and the movable pressing block and the flip pressing plate press the first wire end and the second wire end and the ceramic sheet in between;

[0019] S5: The four shafts rotate slightly, driving the flip pressure plate to rotate, and cooperate with the movable pressure block to rotate and twist the first wire end and the second wire end, thereby increasing the torque of the first wire end and the second wire end in the opposite directions, so that the first wire end and the second wire end can clamp the ceramic sheet more tightly, and the assembly mold moves downward. The assembled ceramic sheet and lead wires move with the feeding tape, and the assembly mold is reset again to assemble the next batch of lead wires and ceramic sheets.

[0020] Technical effects and advantages of the present invention:

[0021] The present invention performs a spread-out assembly of the first and second wire ends of the pin wire by tilting and adjusting the expansion plate during the pushing process of the ceramic sheet, ensuring that each assembled ceramic sheet can be smoothly pushed between the first and second wire ends, effectively preventing the first wire end from abutting against the ceramic sheet, causing the first wire end to be squeezed and deformed and resulting in assembly failure, and clamping the assembled pin wire and the ceramic sheet by a movable pressure block and a flip pressure plate. When the movable pressure block and the flip pressure plate are slightly rotated, the pin wire is slightly twisted to increase the torque between the first and second wire ends, so that the pin wire is clamped more tightly to the ceramic sheet, preventing the ceramic sheet from falling off during the twisting vertical feeding of the feeding tape, resulting in assembly failure, and by slightly twisting the pin wire, the two ends of the pin wire are screwed together, solving the problem of excessive spacing between the first and second wire ends due to wiring.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1, reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a processing device for fuses, including a machine tool, and a feeding tape for bonding and fixing pin wires. An assembly device 1 is arranged on one side of the machine tool. The assembly device 1 is used for assembling the pin wires and ceramic sheets. The pin wires have two wire ends, namely a first wire end and a second wire end. The assembly device 1 includes a pushing device 2 and an assembly mold 3 for assembling ceramic sheets. A plurality of expansion plates 31 are hinged on the assembly mold 3. One end of each expansion plate 31 is connected to the assembly mold 3 through a spring. A plurality of flip pressing plates 32 are arranged at the front end of the assembly mold 3. The flip pressing plate 32 is installed on the assembly mold 3 through a driving member. An upper pressing component 5 connected to the machine tool through a bracket is arranged above the assembly mold 3. The upper pressing component 5 includes a movable pressing block 51 arranged corresponding to the flip pressing plate 32. 31 is tilted and adjusted during the pushing process of the ceramic sheet, and the first and second wire ends of the pin wire are spread out for assembly, ensuring that each assembled ceramic sheet can be smoothly pushed between the first and second wire ends, effectively preventing the first wire end from hitting the ceramic sheet, causing the first wire end to be squeezed and deformed, resulting in assembly failure. The assembled pin wire and ceramic sheet are clamped by the movable pressure block 51 and the flip pressure plate 32. When the movable pressure block 51 and the flip pressure plate 32 are slightly rotated, the pin wire is slightly twisted to increase the torque between the first and second wire ends, so that it clamps the ceramic sheet more tightly, preventing the ceramic sheet from falling off during the vertical feeding of the feeding tape, resulting in assembly failure. By slightly twisting the pin wire, the two ends of the pin wire are screwed together, solving the problem of excessive spacing between the first and second wire ends due to wiring.

[0034] The assembly equipment 1 also includes a disc loader 6 and a feeding device 7. The disc loader 6 is arranged on one side of the feeding device 7 and is used for discharging ceramic sheets. The disc loader 6 includes two feeding discs, and the two feeding discs are driven by a group of motors. Four discharge ports are arranged at the adjacent ends of the disc loader 6 and the feeding device 7. The feeding device 7 includes a three-axis mobile platform 71, and an adsorption member 72 fixed on the three-axis mobile platform 71. The adsorption member 72 includes two rows of adsorption tubes symmetrically arranged for adsorption and feeding of ceramic sheets. The adsorption member 72 also includes an air suction system and a movable plate for installing the two rows of adsorption tubes. The air suction system is fixed on the three-axis mobile platform 71, and the movable plate is installed on the three-axis mobile platform 71. The air suction system is controlled by two air The tube is connected to the movable plate, and there are two ventilation grooves interconnected with the two air pipes in the movable plate. The two rows of adsorption tubes are respectively interconnected with the two ventilation grooves. The four rows of feeding ports can discharge four ceramic sheets at a time. In conjunction with the assembly mold 3, four pin lines can be assembled with the ceramic sheets at a time to improve the assembly efficiency, and the two rows of adsorption tubes are used for loading eight ceramic sheets in batches. While the front row of adsorption tubes is aligned with the assembly mold 3 for loading, the rear row of adsorption tubes is aligned with the pushing bracket 21 to place the ceramic sheets on the pushing bracket 21. During reciprocating loading, the front row of adsorption tubes is used to load the ceramic sheets on the pushing bracket 21 into the assembly mold 3, and the rear row of adsorption tubes loads the ceramic sheets on the discharge port onto the pushing bracket 21, thereby improving the loading accuracy.

The four limiting feed troughs 33 are used to limit the ceramic sheets. When the push rods 211 push the ceramic sheets to move, the limiting feed troughs 33 ensure that the ceramic sheets move horizontally, ensure that the ceramic sheets can be accurately aligned with the pin lines, and improve the installation quality.

[0036] The expansion plate 31 is tilted upwardly at the connection end with the spring, and the other end of the expansion plate 31 is fitted with the upper end surface of the assembly mold 3. The distance between the expansion plate 31 at the spring end and the assembly mold 3 is greater than the thickness of the ceramic sheet. In the original state, the plate surface of one end of the expansion plate 31 is higher than the ceramic sheet, so that the ceramic sheet is always located below the expansion plate 31. When the ceramic sheet is moved by the thrust, the upper end surface of the ceramic sheet contacts the lower end surface of the expansion plate 31. When the movement continues, the other end of the expansion plate 31 is pushed open. The expansion plate 31 is used to expand the first line end. Since the expansion plate 31 is always located between the first line end and the ceramic sheet when the first line end is assembled, it can effectively prevent the ceramic sheet from being against the first line end.

[0037] A two-axis movable platform is arranged below the assembly mold 3. An inner groove for accommodating a driving component is opened inside the assembly mold 3. The two-axis movable platform is used to drive the assembly mold 3 to move. The driving component includes four shafts connected by chains. One ends of the four shafts are respectively connected to the flip pressure plate 32, and one of the shafts is connected to the motor. The motor can drive the shaft to rotate. The four shafts are connected by chains, thereby driving the four shafts to rotate together.

[0038] The upper pressure assembly 5 also includes a main support plate 52, the lower end surface of the main support plate 52 is provided with a groove for accommodating the movable pressure block 51, and the upper end surface of the movable pressure block 51 is hinged to the main support plate 52, the main support plate 52 is fixed to a bracket connected to the machine tool through a cylinder, and the movable pressure block 51 is hinged to the main support plate 52.

The plate surface of the limiting support plate 92 located in the concave position is arranged in the soldering box 91. A plurality of row rods are connected below the plate surface of the limiting support plate 92 located in the concave position, and the plate bodies at both ends of the limiting support plate 92 are arranged on the outer sides of both ends of the soldering box 91. The limiting support plate 92 is connected to a two-axis driving module below, and a driver for lifting the soldering box 91 is installed below the machine tool.

S4: the upper pressing assembly (5) and the movable pressing block (51) are pressed downward, so that the movable pressing block (51) is pressed against the ceramic sheet, the pushing bracket (21) drives the push rod (211) to reset, and the assembly mold (3) moves in the same direction as the pushing bracket (21) under the drive of the two-axis moving platform, so that the flip pressing plate (32) moves to a position corresponding to the movable pressing block (51), and the movable pressing block (51) and the flip pressing plate (32) press the first wire end, the second wire end and the ceramic sheet therebetween; S5: The four shafts rotate slightly, driving the flip pressure plate (32) to rotate, and cooperate with the movable pressure block (51) to rotate and twist the first wire end and the second wire end, thereby increasing the torque of the first wire end and the second wire end in the opposite directions, so that the first wire end and the second wire end clamp the ceramic sheet more tightly, and the assembly mold (3) moves downward, and the assembled ceramic sheet and lead wires move with the feeding tape, and the assembly mold (3) is reset again to assemble the next batch of lead wires and ceramic sheets.
