The following describes a method for using the rapid jig 1 for surface mounting devices, comprising the steps of:
step S1, as shown in fig. 16 to 18, opens the cover case 3, rolls the carrier tape 9 carrying the surface mount device into the placement slot 41, and draws the head of the carrier tape 9 from the placement opening 411 to the step roller 5S, so that the synchronization protrusion 53S of the step roller 5S is inserted into the corresponding carrier hole 92 of the carrier tape 9, and at the same time, removes a part of the cover film 93 on the base 90 of the carrier tape 9, and draws the cover film 93 from the pull-up window 25, and passes through the base tape channel 113 of the top tray 111 of the drawing assembly M, and finally, the cover film 93 is clamped by the pair of drawing resilient tabs 12 of the drawing assembly M, as shown in fig. 23. Note that the coating film 93 on the substrate 90 of the carrier tape 9 covers only the surface mount devices 91 and does not cover the carrier holes 92;
step S2, as shown in fig. 27, the user presses the depressing rack 8 by hand, as shown in the direction P, whereupon the depressing rack 8 slides down in the direction F1 until the bottom of the rack body 81 compresses the return spring 6S to the maximum extent without further compression, and during the sliding down of the rack body 81, the drive gear 3G rotates counterclockwise, as shown in the direction R3, and at the same time, the one-way ratchet 4G rotates clockwise, as shown in the direction R4. The one-way ratchet 4G synchronously drives the stepping rotating wheel 5S to rotate clockwise through the connecting roller 5, the carrier tape 9 is pulled out from between the second traction window 31 and the first traction window 24 by the stepping rotating wheel 5S through the matching of the synchronous protrusion 53S and the carrying hole 92, and at this time, a user can take down the surface mounting device 91 of the carrier tape 9 by using tweezers or a vacuum chuck for use.
The pulling member M is moved in the direction F2 by the engagement of the driving gear 3G with the lower rack gear 102 of the lower tray portion 10 of the pulling member M while the driving gear 3G is rotated counterclockwise. In the process that the pulling assembly M moves in the direction F2, as shown in fig. 26 and 27, the abutting pieces 122 of the pair of pulling springs 12 tightly abut against two side surfaces of the film 93 under the action of the spring springs 13, so that the film 93 moves in the direction F2 synchronously with the pulling assembly M, and then the film 93 continues to be peeled off from the substrate 90 of the carrier tape 9, and a new surface mount device 91 is exposed;
in step S3, the user releases the push-down rack 8, the return spring 6S starts to return, the push-down rack 8 moves upward, and the drive gear 3G rotates clockwise, so that the drive gear 3G engages with the lower rack 102 of the lower tray portion 10 of the pulling unit M, thereby returning the pulling unit M to the initial position close to the pull-up window 25 as shown in fig. 24. When the driving gear 3G rotates clockwise, the one-way ratchet 4G rotates counterclockwise freely, and due to the characteristic of one-way rotation of the one-way ratchet 4G, the rotation of the one-way ratchet 4G cannot synchronously drive the connecting roller 5, so that the stepping rotating wheel 5S remains stationary, the carrier tape 9 also remains stationary, and no new surface mount device 91 is sent out.
It should be noted that the quick clamp 1 for surface mount devices uses the connecting flange 28 and the flange screw hole 281, and a user can fix the clamp to any material such as wood, iron, etc. by using screws.
In addition, the pulling member M is an optional member for the quick clamp for surface mount devices 1, and can be removed by a user.
In addition, the user can finely adjust the descending stroke of the pressing rack 8 by adjusting the screw rod 71, so that the stepping numerical value of the stepping rotating wheel 5S is changed, and the loading holes 92 with different intervals are easily matched. And step-by-step runner 5S also can carry out quick replacement, convenient and fast.
Because single manual feeding is adopted, the carrier tape automatically peels off the coated film, the operation is easy, and the method is particularly suitable for welding and taking materials of surface-mounted devices.
As shown in fig. 28 and 29, a second embodiment of the rapid jig for surface mounting devices according to the present invention is provided, in which a first auxiliary opening 2K is provided on the outer wall of the bottom case 2 and a second auxiliary opening 3K is provided on the outer wall of the cover case 3. When it is necessary to convey a large roll of the carrier tape, the carrier tape can be directly fed from the first auxiliary opening 2K and the second auxiliary opening 3K to the stepping reel 5S without passing through the placement groove 41.
As shown in fig. 30 to 33, there is a third embodiment of the rapid jig for a surface mount device according to the present invention. At this time, an elongated base S2 is provided, a sinking groove S21 is provided in the middle of the base S2, a plurality of front bayonets S22 are provided at one side of the sinking groove S21, a plurality of rear bayonets S23 are provided at the other side of the sinking groove S21, and the positions of the rear bayonets S23 correspond to the front bayonets S22 one by one. A fixed clip column S221 is arranged in the front bayonet S22, a jack S232 is arranged in the rear bayonet S23, and a zipper S25 and a zipper spring S24 are arranged in the jack S232.
The user snaps the connection flange 28 of the quick clamp for surface mount devices 1 between the corresponding front and rear bayonets S22 and S23 and pulls the zipper S25, so that the zipper S25 is pushed into the flange screw hole 281 of the corresponding connection flange 28, and quick mounting and dismounting are easily achieved. This embodiment is suitable for multiple material selection.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
