Detailed Implementation

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Example 1: refer to Figure 1-5A fixture for clamping various types of short strip materials in a chip mounter includes a base plate 1, a cover plate 2 on the top of the base plate 1, several recessed grooves 3 of different widths inside the base plate 1, a first through groove 4 at the bottom of the recessed grooves 3, several positioning pins 5 fixedly connected to the top of the recessed grooves 3, several first magnetic blocks 6 fixedly sleeved inside the base plate 1, a second through groove 7 adapted to the first through grooves 4 inside the cover plate 2, a second magnetic block 8 adapted to the first magnetic blocks 6 fixedly sleeved inside the cover plate 2, and a fixture adapted to the positioning pins 5 inside the cover plate 2. Two support blocks 13 are provided at the bottom of the bottom plate 1 of the clearance groove 9. The top of the support block 13 is provided with a stepped bearing surface 14. A third magnetic block 15 is fixedly sleeved on both sides of the bottom of the support block 13. By setting two support blocks 13 at the bottom of the bottom plate 1, the bottom plate 1 is raised to a certain height, thereby reserving sufficient space for the bottom of the material strip protruding from the first through groove 4 of the bottom plate 1. By setting the third magnetic block 15, the support block 13 can form a stable adsorption with the tray and stably clamp the bottom plate 1, preventing the tooling from shifting or falling off due to equipment vibration during the feeding process.

[0014] Specifically, the device uses several recessed grooves 3 on the base plate 1 to accommodate various types of short strips. The circular hole on one side of the strip is accurately fitted onto the surface of the positioning pin 5, achieving rapid positioning and stable placement of the strip, effectively preventing the strip from shifting during feeding. The cover plate 2, through the precise cooperation of the positioning hole 11 and the positioning pin 10, can quickly and accurately fit with the base plate 1, greatly improving clamping efficiency. The first magnetic block 6 on the base plate 1 and the second magnetic block 8 on the cover plate 2 attract each other, making the cover plate 2 tightly pressed against the top of the base plate 1, making opening and closing convenient and facilitating frequent replacement of different types of strips. The device is easy to operate, improving feeding reliability and production efficiency, and is especially suitable for the rapid clamping and feeding needs of short strips in multi-variety, small-batch production scenarios.

[0015] refer to Figure 3 and Figure 4 Positioning pins 10 are fixedly sleeved on both sides of the top of the base plate 1. Positioning holes 11 that match the positioning pins 10 are opened inside the cover plate 2. By fixing the positioning pins 10 on both sides of the top of the base plate 1 and opening the positioning holes 11 that match them in the cover plate 2, the cover plate 2 and the base plate 1 can be quickly inserted and positioned, ensuring the positional accuracy of the two when the mold is closed and avoiding misalignment.

[0016] refer to Figure 3 The base plate 1 has two square holes 12 inside. By opening two square holes 12 inside the base plate 1, the overall weight of the base plate 1 is effectively reduced, making the tooling easier for the operator to hold and move.

[0017] refer to Figure 3There are four sinking grooves 3, with widths of 8 mm, 12 mm, 16 mm and 24 mm respectively, which allows the same tooling to be adapted to a variety of standard specifications of short strips without the need to change special fixtures for each strip, thus significantly improving the versatility of the tooling.

[0018] Brief description of the usage process: Place the round hole at the end of the material strip onto the surface of the positioning pin 5, so that the material strip is placed on the top of the sink trough 3. Then place the cover plate 2 on the top of the base plate 1. The cover plate 2 is quickly positioned and attached through the cooperation of the positioning hole 11 and the positioning pin 10. The base plate 1 and the cover plate 2 are tightly attached and fixed through the cooperation of the first magnetic block 6 and the second magnetic block 8, which facilitates the clamping and feeding of various types of short material strips.
