The stitch repair and shaping device includes: a frame seat 1, and a back plate 2 is fixed on the top thereof, a microscope 3 is fixed on the back plate 2, and a repair table 6 is arranged below the microscope 3, and a concave frame 4 is arranged above the frame seat 1, and a support column 5 is fixed on the bottom inner wall of the concave frame 4, and its top end is fixedly connected to the repair table 6, and linkage shafts 10 are rotatably installed on the inner walls of both sides of the concave frame 4, and a rectangular frame 11 is fixed on the ends of the two linkage shafts 10 that are close to each other, and two connecting bars 13 are arranged between the two rectangular frames 11, and a fixing rod 14 and a fixing rod 2 15 are fixed on the sides of the two connecting bars 13 that are close to each other, that is, the shape It is composed of two fixing rods 14 and two fixing rods 2 15, wherein, in the initial state, the fixing rod 2 15 is located directly below the fixing rod 14, and a straight-edge splint 16 is fixed to one end of the two fixing rods 14 close to each other, and an arc-edge splint 17 is fixed to one end of the two fixing rods 2 15 close to each other, and the bottom of the straight-edge splint 16 and the top of the arc-edge splint 17 are flush with the top and bottom of the repair table 6 respectively, that is, the spacing between the straight-edge splint 16 and the arc-edge splint 17 is the same as the thickness of the repair table 6, thereby ensuring that the straight-edge splint 16 and the arc-edge splint 17 can move horizontally on the repair table 6.
[0022] In the above method, in order to be able to adjust the height of the repair table 6 while allowing the straight-edge clamp 16 and the arc-edge clamp 17 to rise and fall with it, two support plates are fixed on the top of the frame seat 1, and the same insertion rod 9 is slidably installed on the two support plates, and a sliding column 7 is slidably installed on the top of the frame seat 1, and its top end is fixedly connected to the concave frame 4, and a plurality of insertion holes 8 are opened on the sliding column 7. In the initial state, the insertion rod 9 passes through the uppermost insertion hole 8 and contacts with its inner wall, that is, the two are in a plug-in relationship, and the insertion rod 9 is inserted into the insertion hole 8 to firmly hold the concave frame 4 at a specified height.
[0023] In the present method, in order to be able to clamp and fix the probe card by using two straight-edge clamps 16 or two arc-edge clamps 17, cylinders 12 are fixed on the inner walls of the two rectangular frames 11 on one side close to each other, and the output shafts of the two cylinders 12 are respectively fixedly connected to the two connecting strips 13, and the output shafts of the cylinders 12 are movably connected to the rectangular frames 11, and the probe card is fixed by the extension and retraction of the output shafts of the cylinders 12. In addition, two guide rods are slidably installed on the top of the frame seat 1, and the top ends of the two guide rods are fixedly connected to the concave frame 4. Through the design of the guide rods, the concave frame 4 can only be lifted and lowered linearly.
[0024] In this embodiment, in order to make the straight edge clamp plate 16 and the arc edge clamp plate 17 alternate positions, and at the same time, in order to make the two linkage shafts 10 rotate simultaneously, the same transmission rod 18 is rotatably installed on the inner walls of both sides of the concave frame 4, and the transmission rod 18 penetrates the support column 5 and is movably connected to the support column 5, and horizontal platforms are fixed on the inner walls of both sides of the concave frame 4, and connecting rods 19 are rotatably installed on the two horizontal platforms, and two bevel teeth 1 are fixedly sleeved on the transmission rod 18, and bevel teeth 2 are fixed at the bottom ends of the two connecting rods 19, and the two bevel teeth 1 are respectively meshed with the two bevel teeth 2, and are fixed on the top ends of the two connecting rods 19. There are three bevel teeth, and the two linkage shafts 10 are fixedly provided with four bevel teeth, and the two bevel teeth three are respectively meshed with the two bevel teeth four. In addition, in order to provide rotational power for the transmission rod 18, a central rotating shaft is rotatably installed on the support column 5, and the central rotating shaft and the transmission rod 18 are fixedly provided with round teeth, and the two round teeth are meshed with each other. A motor is fixed on one side of the support column 5, and its output shaft is fixedly connected to one end of the central rotating shaft. In this way, the two linkage shafts 10 can be rotated simultaneously by starting the motor, under the meshing of the round teeth, the meshing of the bevel teeth one and the bevel teeth two, and the meshing of the bevel teeth three and the bevel teeth four.
[0025] In this method, in order to prevent the output shaft of the cylinder 12 from rotating, two limiting rods are slidably installed on the side where the two rectangular frames 11 are close to each other, and one end of the two corresponding limiting rods is fixedly connected to the corresponding connecting strips 13. The limiting rods are used to indirectly limit the cylinder 12 to ensure that the connecting strip 13 can only perform linear horizontal movement.
[0026] The working principle of the stitch repair and shaping device provided by the utility model is as follows:
[0027] When repairing the pins of the rectangular probe card, the rectangular probe card is first placed on the repair table 6, and then the output shafts of the two cylinders 12 are started to extend, and the two straight-edge clamping plates 16 are moved towards each other under the drive of the connecting strip 13 until the two straight-edge clamping plates 16 are in contact with the probe card, and the rectangular probe card is clamped and fixed. Then, the pins can be repaired under the observation of the microscope 3 and with the help of tools;
[0028] In subsequent use, when it is necessary to repair the pins of the circular probe card, the circular probe card is placed on the repair table 6, and then the motor is started in the forward direction, and its output shaft drives the central shaft to rotate. At this time, through the meshing between the two round teeth, the transmission rod 18 can be driven to rotate, and then under the meshing of the bevel teeth 1 and 2, the two connecting rods 19 are driven to rotate, and then, under the meshing of the bevel teeth 3 and 4, the two linkage shafts 10 are driven to rotate, which will lead the two rectangular frames 11 to rotate. After the rectangular frame 11 rotates 180°, the motor is turned off. At this time, the straight edge clamp 16 and the arc edge clamp 17 alternate positions, that is, at this time, the arc edge clamp 17 is directly above the straight edge clamp 16, and then the output shafts of the two cylinders 12 are started to extend, and the circular probe card can be clamped and fixed by the two arc edge clamps 17, and then the repair can be carried out. Afterwards, when it is necessary to change back to the straight edge clamp 16, it is only necessary to start the motor in the reverse direction to rotate the rectangular frame 11 180°.
[0029] In addition, during use, if it is necessary to adjust the height of the repair table 6 according to actual conditions, in order to ensure that the straight-edge splint 16 and the arc-edge splint 17 rise or fall with it, the plug rod 9 can be pulled out first, so that the slide column 7 loses the clamping restriction, and then the concave frame 4 is lifted up, so that the repair table 6 and the straight-edge splint 16 and the arc-edge splint 17 rise together. After rising to the approximate height position, the position of the slide column 7 is slightly adjusted so that the socket 8 closest to the position is horizontally aligned with the plug rod 9, and then the plug rod 9 is inserted into it.
[0030] Compared with the related art, the stitch repair and shaping device provided by the utility model has the following beneficial effects:
[0031] The utility model provides a pin repair and shaping device. By setting a rotatable rectangular frame 11, the straight-edge clamping plate 16 and the arc-edge clamping plate 17 designed one above and one below can be replaced in position, so that when repairing the pins of a rectangular probe card, the straight-edge clamping plate 16 can be activated, and when repairing the pins of a circular probe card, the arc-edge clamping plate 17 can be activated, thereby improving the overall application range of the device and enhancing its universality. In addition, by fixing the repair table 6 in the concave frame 4, the repair table 6 can be raised or lowered together with the concave frame 4, so as to ensure that the straight-edge clamping plate 16 and the arc-edge clamping plate 17 can be adjusted synchronously with the repair table 6, and their normal use will not be delayed.
