[0027] Please refer to Figure 1 Figure 4 The embodiment provides a large-capacity nozzle clamping jig, comprising:

[0028] The connecting bottom plate 1 is internally provided with a weight-reducing through hole, a plurality of support strips 110 connected with the frame of the connecting bottom plate 1 are arranged in the weight-reducing through hole, and the support strips 110 divide the weight-reducing through hole into a plurality of weight-reducing sub-holes 120.

[0029] The weight-reducing through hole avoids the use of a whole solid plate body for the connecting bottom plate 1, thereby reducing the weight of the connecting bottom plate 1 and lowering the cost of the connecting bottom plate 1. Meanwhile, the support strips 110 play a connecting and supporting role.

[0030] The nozzle positioning plate 2 is provided with a plurality of nozzle accommodating holes, and a cover plate (not shown) is slidably connected to the nozzle positioning plate 2.

[0031] The structure of the nozzle positioning plate 2 is basically the same as the structure and function of the nozzle jig in the prior art. For example, a plurality of nozzle accommodating holes are arranged on the nozzle positioning plate 2, and a cover plate (not shown) is slidably connected to the nozzle positioning plate 2. The cover plate is provided with a corresponding gourd-shaped locking hole corresponding to each nozzle accommodating hole. The nozzle positioning plate 2 plays a connecting role with the lower clamping seat, that is, corresponding to the connecting bottom plate 1, a new structure scheme is adopted.

[0032] The support strip 110 is provided with a plurality of connecting portions 111, and a plurality of clamping members 3 are connected with the connecting portions 111, respectively.

[0033] By reasonably arranging the plurality of clamping holes 210 and clamping members 3, the nozzle positioning plate 2 is installed and fixed to the connecting bottom plate 1, thereby avoiding the use of traditional screws and pressing blocks to fix the nozzle positioning plate 2 and the connecting bottom plate 1, which is time-consuming and laborious, and then using a side edge overturning type pressing mechanism to press the nozzle positioning plate 2 and the connecting bottom plate 1 together, which has a complex structure and high cost. ​

[0034] The clamp tool corresponds to the upper and lower lifting mold closing mode suction nozzle cleaning machine (not shown), and the upper half and the lower half of the cleaning machine are closed to form a cleaning chamber, and the suction nozzle positioning plate 2 and the connecting bottom plate 1 are pressed and fixed together.

[0035] The prying member 4 is rotationally connected with the connecting bottom plate 1, and after the suction nozzle positioning plate 2 is connected with the connecting bottom plate 1 through the clamping member 3, the prying member 4 includes a prying plate 410 located at the lower end of the bottom surface of the suction nozzle positioning plate 2 and a pressing portion 420 located beside the side wall of the suction nozzle positioning plate 2.

[0036] When the suction nozzle is cleaned by the cleaning machine, the pressing portion 420 can be pressed, and since the prying member 4 is rotationally connected with the connecting bottom plate 1, the prying plate 410 moves in the direction opposite to the pressing portion 420, naturally prying the bottom surface of the suction nozzle positioning plate 2, so that the clamping member 3 is separated from the clamping hole 210, the connection between the suction nozzle positioning plate 2 and the connecting bottom plate 1 is released, and the suction nozzle positioning plate 2 is conveniently taken out one by one.

[0037] Through the above structure, at least two suction nozzle positioning plates 2 can be fixed to one connecting bottom plate 1, and the connecting bottom plate 1 connected with the driving connecting bottom plate 1 and the suction nozzle positioning plate 2 can also be provided with only one conveying device for moving and switching between the feeding station and the cleaning feeding station, so that more suction nozzles to be cleaned can be conveyed, and the cost is saved. At the same time, the connection and disconnection of the suction nozzle positioning plate 2 and the connecting bottom plate 1 is flexible and convenient to operate, and the suction nozzle positioning plate 2 is not designed as a large structure with at least two separate suction nozzle positioning plates 2, so that a large capacity of suction nozzles to be cleaned can be obtained, and the suction nozzle positioning plate 2 can be taken out and put in individually, so that the weight is not heavy and the operation of manual or automatic equipment is convenient.

[0038] Please refer to Figure 1 and Figure 3 , the connecting portion 111 is a nut column, and the clamping member 3 is provided with a threaded rod 310 matched with the threaded hole of the nut column.

[0039] This connection is stable, and when the clamping member 3 is worn, it can be easily disassembled and replaced individually, thereby enhancing the convenience of maintenance, reducing the cost of maintenance, and avoiding the replacement of the entire connecting bottom plate 1.

[0040] Please refer to Figure 2 and Figure 4 , the clamping member 3 is provided with a snap type connector 320, and the clamping hole 210 is a snap hole.

[0041] The snap is also called as the snap fastener, the snap type connector 320 is also the part of the male head in the snap, which includes the expansion part 321 similar to the ball head, and the neck-in concave part 322 connecting the expansion part 321 and the threaded rod 310.

[0042] Please refer to Figure 4 , the clamping piece 3 is provided with a screwing groove 330.

[0043] The screwing groove 330 can be a character-shaped groove, or a cross-shaped or inner hexagonal hole which can be operated by a common screwdriver tool. Through the screwing groove 330, the threaded rod 310 is conveniently screwed into or out of the threaded hole of the nut column.

[0044] Please refer to Figure 1 and Figure 3 , the prying piece 4 includes an elastic sheet 430, one end of which is connected with the connecting bottom plate 1, and the other end of which is connected with the prying plate 410.

[0045] Preferably, the elastic sheet 430 is a straight plate-shaped elastic metal sheet, which can be made of steel. The prying piece 4 is rotationally connected with the connecting bottom plate 1 through the elastic sheet 430, and after the pressing part 420 is cancelled, the elastic sheet 430 automatically keeps the prying piece 4 reset through elasticity.

[0046] Please refer to Figure 3 , the elastic sheet 430 is detachably connected with the connecting bottom plate 1 through a screw.

[0047] The elastic sheet 430 is provided with a screw connecting hole. Such a detachable structure through a screw facilitates the replacement of the elastic sheet 430 after the fatigue strength is reached.

[0048] Please refer to Figure 1 and Figure 3 , the guide positioning rod 5 is connected with the support strip 110, and the suction nozzle positioning plate 2 is provided with a guide positioning hole 220 corresponding to the guide positioning rod 5.

[0049] Preferably, the end of the guide positioning rod 5 is chamfered, which facilitates the connection and alignment of the suction nozzle positioning plate 2 with the connecting bottom plate 1.

[0050] Please refer to Figure 1 and Figure 3 , the number of the suction nozzle positioning plates 2 is three.

[0051] Please refer to Figure 1 and Figure 2 , the projection profile of the suction nozzle positioning plate 2 is rectangular, and one corner of the suction nozzle positioning plate 2 is provided with an avoidance groove 230 avoiding the prying piece 4.

[0052] The structure is reasonable in layout, so that the overall outer contour of the connecting bottom plate 1 is a regular rectangle, and there is no need to additionally design a position for arranging the prying member 4.
