[0005] This utility model discloses a universal quick-change suction cup structure, including: a suction cup part, a suction cup base plate, a suction cup mounting rod, a first locking member, a locking seat, a second locking member, a universal ball and a connecting seat;

[0006] The suction cup part is mounted on the suction cup base plate, and the suction cup base plate is mounted on one end of the suction cup mounting rod;

[0007] The other end of the suction cup mounting rod is placed in the receiving groove of the locking end of the locking seat. The first locking member is sleeved on the outside of the suction cup mounting rod, and one end of the first locking member is screwed onto the external thread of the locking end of the locking seat. By screwing the first locking member into the locking seat in the forward or reverse direction, the suction cup mounting rod can be tightened or loosened.

[0008] The fixed end of the locking seat is fixed to the universal ball, and the universal ball is accommodated in the ball cavity formed by the second locking member and the connecting seat. The second locking member is provided with a clearance hole for the locking seat to pass through. The second locking member is screwed to the connecting seat. Loosening the second locking member allows the universal ball to float in all directions within a preset range. Tightening the second locking member clamps and fixes the universal ball.

[0009] As a further improvement of this utility model, the suction cup part is fixedly installed on one side of the suction cup base plate by countersunk screws, and the suction cup mounting rod is screwed and fixed on the other side of the suction cup base plate.

[0014] As a further improvement of this utility model, the connecting seat and the locking seat are provided with wrench grooves.

[0015] As a further improvement of this utility model, the outer surfaces of the first locking member and the second locking member are knurled.

[0016] As a further improvement of this utility model, the suction cup base plate, suction cup mounting rod, first locking member, locking seat, second locking member, universal ball and connecting seat are provided with channels that communicate with the suction holes of the suction cup part.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] When the first locking member is screwed into the thread on the locking seat, the groove wall (opening piece) of the receiving groove of the locking seat is squeezed and retracted towards the axis to hold the suction cup mounting rod tightly, which improves the convenience of suction cup replacement and achieves a rigid connection between the suction cup and the equipment after replacement.

[0019] This invention places the universal ball in the ball cavity formed between the connecting seat and the second locking member. After the suction cup is leveled, the universal ball is locked by the second locking member, which enables convenient adjustment of the level after the suction cup is replaced.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings:

[0028] like Figures 1-4 As shown, this utility model provides a universal quick-change suction cup structure, which enables quick replacement of the suction cup when it needs to be compatible with chips of different sizes on chip mounting equipment; it includes: suction cup part 1, suction cup base plate 2, suction cup mounting rod 4, first locking member 5, locking seat 6, second locking member 7, universal ball 8 and connecting seat 9; wherein, the suction cup part 1, suction cup base plate 2, suction cup mounting rod 4, first locking member 5, locking seat 6, second locking member 7, universal ball 8 and connecting seat 9 are axially arranged from one side to the other side.

[0029] Specifically:

[0030] The suction cup part 1 of this utility model is fixedly installed on one side of the suction cup base plate 2 by countersunk screws 3. That is, the suction cup base plate 2 is provided with threaded holes, and the suction cup part 1 is provided with corresponding threaded holes or countersunk screw through holes. The countersunk screws 3 are screwed and fixed in the threaded holes of the suction cup base plate 2, and the screw head of the countersunk screws 3 is inserted into the threaded holes or countersunk screw through holes of the suction cup part 1. Preferably, the suction cup part 1 is provided with two threaded holes or countersunk screw through holes, and the two threaded holes or countersunk screw through holes are located on both sides of the "I"-shaped suction hole. The suction cup mounting rod 4 is screwed and fixed on the other side of the suction cup base plate 2. The installed suction cup can be replaced according to the usage requirements. That is, one end of the suction cup mounting rod 4 is provided with external threads, and the other side of the suction cup base plate 2 is provided with matching internal threaded holes, so that the suction cup mounting rod 4 is screwed and fixed on the suction cup base plate 2. The suction cup part 1 of this utility model has a preset number of suction holes and avoidance points arranged on one side of the suction surface according to the chip adsorption process requirements; the mounting surface side of the suction cup part 1 has a certain number of acupoints arranged to connect and communicate with each suction hole.

[0031] The other end of the suction cup mounting rod 4 of this utility model is placed in the receiving groove of the locking end of the locking seat 6. The first locking member 5 is sleeved on the outside of the suction cup mounting rod 4, and one end of the first locking member 5 is screwed onto the external thread of the locking end of the locking seat 6. By screwing the first locking member 5 into the locking seat 6 in the forward or reverse direction, the suction cup mounting rod 4 can be tightened or loosened.

[0032] In one embodiment, the locking end of the locking seat 6 has a receiving groove. The groove wall is a thin-walled structure (with a certain elasticity, it can converge towards the center when compressed and return to its original position when released). The groove wall also has an axial notch to facilitate its convergence towards the center. An external thread is formed on the outer circumferential surface of the groove wall to mate with the internal thread of the first locking member 5. The internal thread hole of the first locking member 5 has a gradually narrowing internal thread hole structure from the open end inwards. Figure 2 As shown; when the first locking member 5 rotates toward the locking seat 6, the groove wall of the receiving groove of the locking seat 6 is squeezed towards the center by the internal threaded hole wall of the first locking member 5, thereby clamping and fixing the suction cup mounting rod 4, thus completing the fixation of the suction cup mounting rod 4. Reversing the rotation of the first locking member 5 moves it away from the locking seat 6, and the groove wall of the receiving groove of the locking seat 6 slowly returns to its original position, thereby releasing the clamping and fixing of the suction cup mounting rod 4, thus completing the disassembly of the suction cup mounting rod 4.

[0033] The fixed end of the locking seat 6 of this utility model is screwed into the internal threaded hole of the universal ball 8. The universal ball 8 is accommodated in the ball cavity formed by the second locking member 7 and the connecting seat 9. The second locking member 7 is provided with a clearance hole for the locking seat 6 to pass through. The external thread of the second locking member 7 is screwed and fixed to the internal thread of the connecting seat 9. When the second locking member 7 is loosened, the universal ball 8 can float in all directions within a preset range. During the floating process, the flatness of the suction cup installed on the patch device can be changed. When the second locking member 7 is tightened, the universal ball 8 is clamped and fixed.

[0034] The connector 9 of this utility model is equipped with a flat-headed set screw 10, which is used to install the universal quick-change suction cup structure on the automated chip placement equipment.

[0035] The connecting seat 9 and locking seat 6 of this utility model are provided with wrench grooves, and the outer surfaces of the first locking member 5 and the second locking member 7 are knurled to facilitate installation, replacement and adjustment.

[0036] The suction cup base plate 2, suction cup mounting rod 4, first locking member 5, locking seat 6, second locking member 7, universal ball 8 and connecting seat 9 of this utility model have a channel that communicates with the suction hole of the suction cup part 1. This channel is a negative pressure channel. At the same time, the suction hole of the suction cup part 1 can also be directly connected to an external negative pressure pipeline to complete the negative pressure adsorption.

[0037] The advantages of this utility model are:

[0038] After the suction cup is replaced, this utility model uses a threaded connection to lock the parts, which improves the overall height of the quick-change structure and can be applied to situations where the surface mount technology (SMT) has higher precision requirements.

[0039] When the first locking member is screwed into the thread on the locking seat, the groove wall (opening piece) of the receiving groove of the locking seat is squeezed and retracted towards the axis to hold the suction cup mounting rod tightly, which improves the convenience of suction cup replacement and achieves a rigid connection between the suction cup and the equipment after replacement.

[0040] This invention places the universal ball in the ball cavity formed between the connecting seat and the second locking member. After the suction cup is leveled, the universal ball is locked by the second locking member, which enables convenient adjustment of the level after the suction cup is replaced.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
