Description

Technical Field

[0001] The invention relates to the technical field of chip placement machine trays, and in particular to an anti-collision mechanism for a chip placement machine tray. Background Art

[0002] Chip placement machines play an important role in automated chip assembly and are commonly used for chip placement. As shown in the figure, in existing chip placement machines, the chips to be placed are placed in a matrix on a jig plate, which is mounted on a tray. Trays containing different jig plates are placed layer by layer in a tray cabinet. To access and place different chips in the tray cabinet, the tray cabinet is equipped with a lift and a lifting mechanism that controls the lift to different heights. When a chip needs to be removed, the lift mechanism drives the lift to the corresponding height, and then a pull-out mechanism on the lift pulls out the corresponding tray. The suction head then picks up the chip from the jig plate for use. When the jig plate needs to be returned to the tray cabinet, the pull-out mechanism pushes the tray back into the tray cabinet.

[0003] In actual use, when the above-mentioned suction head absorbs patches, it is inevitable that the patches will fall onto the jig plate due to unstable suction. When this happens, the patches are likely to collide with adjacent trays when the tray is pushed back into the tray cabinet, causing malfunctions. At the same time, the patches scattered on the jig plate will affect the suction head's next attempt to absorb patches, further causing unstable suction. To address the above problems, the present invention provides a tray anti-collision mechanism for a placement machine. Summary of the Invention

[0004] In response to the above-mentioned technical deficiencies, the purpose of the present invention is to provide an anti-collision mechanism for the tray of a patch machine.

The tray 2 is placed on the platform 3 or pushed back into the tray cabinet 1; specifically, a number of pallet pairs are evenly installed between the opposite side walls of the tray cabinet 1, and the pallet pair includes two symmetrical pallets 11. The upper surface of the pallet 11 is provided with a strip-shaped limiting groove 111, and the tray 2 is slidably installed in the corresponding two strip-shaped limiting grooves 111 to ensure that the tray 2 is stably and evenly installed in the tray cabinet 1 and can be stably slid out and pushed in; in fact, the tray cabinet 1, the lifting mechanism 31 and the two-way telescopic rod 4 for locking the tray 2 are all existing technologies in this field and will not be described in detail here.

[0045] See also Figure 2 、 Figure 3 as well as Figure 9 、 Figure 15 、 Figure 16As shown, a horizontal cleaning brush 6 is slidably mounted on the front upper surface of the lifting platform 3; the two-way telescopic rod 4 is rotatably mounted to the receiving plate 7 via two struts 41; a collection box 71 is mounted on the rear of the lifting platform 3. In this embodiment, the end of the component closest to the pallet cabinet 1 is defined as the front end, and the end away from the pallet cabinet 1 is defined as the rear end; the horizontal cleaning brush 6 is located behind the front protrusion 36. Specifically, the strut 41 is a curved rod or an inclined rod, the lower end of which is fixedly connected to the outer wall of the two-way telescopic rod 4. The receiving plate 7 has two parallel grooves 71 on its lower bottom surface, extending through the front end of the receiving plate 7. The upper end of the strut 41 is hinged between the two side walls of the groove 71. A protruding plate 72 is provided at the front of the receiving plate 7, which matches the notch 21. The height of the support rod 41 is designed to be reasonable. Under the support of the support rod 41, when the receiving plate 7 is horizontal, the lower surface of the receiving plate 7 is coplanar with the upper surface of the side top plate 34, and the upper surface of the receiving plate 7 is coplanar with the upper surface of the tray 2. The protruding plate 72 is matched and installed in the notch 21. In fact, the receiving plate 7 and the protruding plate 72 are elastic plates connected as one piece, and an arc surface is provided below the front end of the protruding plate 72 to facilitate the matching or separation of the protruding plate 72 with the notch 21. The collection box 71 is installed on the upper surface of the rear end of the bottom plate 32. The front side plate of the collection box 71 is lower than the rear side plate. The left and right side plates of the collection box 71 are trapezoidal plates. The high end of the trapezoidal plate is connected to the rear side plate of the collection box 71, and the low end of the trapezoidal plate is connected to the front side plate of the collection box 71. The collection box 71 is wider than the receiving plate 7, which makes it easy for the protruding plate 72 to extend into the collection box 71 after rotation and tilting, so as to collect the patches. In addition, the two sides of the receiving plate 7 are integrally connected to the limiting plates 73, and the two limiting plates 73 are located outside the tray 2; they limit the patches in the receiving plate 7 to prevent them from scattering during movement.

[0046] See also Figure 5 、 Figure 11 、 Figure 15 、 Figure 16 as well as Figure 19As shown, when the two-way telescopic rod 4 pulls out the tray 2, the horizontal cleaning brush 6 moves upward under the drive of the driving mechanism, so that the horizontal cleaning brush 6 is away from the jig plate 5; that is, when the tray 2 is dragged out of the tray cabinet 1, the horizontal cleaning brush 6 does not contact the jig plate 5, so as not to affect the extraction of the tray 2. When the two-way telescopic rod 4 pushes the tray 2 back, the horizontal cleaning brush 6 moves downward under the drive of the driving mechanism, so that the horizontal cleaning brush 6 contacts the cleaning jig plate 5; that is, when the tray 2 begins to be pushed back into the tray cabinet 1, the horizontal cleaning brush 6 contacts the jig plate 5, thereby cleaning the patches scattered on the jig plate 5. As the jig plate 5 moves into the tray cabinet 1, the scattered patches are cleaned into the receiving plate 7, so as to prevent the scattered patches from hitting the adjacent tray 2. When the bidirectional telescopic rod 4 is located at the rear of the lifting platform 3, since the lower side of the front of the receiving plate 7 is hinged to the high end of the support rod 41, under the action of the gravity of the receiving plate 7, the receiving plate 7 tilts downward and transports the cleaned patches 51 into the collection box 71; when the bidirectional telescopic rod 4 moves from the rear to the front of the lifting platform 3, the receiving plate 7 gradually rotates and is spliced ​​with the tray 2 to form a complete plane, which is used to receive the patches 51 swept down by the horizontal cleaning brush 6.

A connecting groove 221 is provided at the inner end of the rubber block 22. The two output ends of the two-way telescopic rod 4 extend into the connecting groove 221 to achieve locking. When the two-way telescopic rod 4 slides on the upper surface of the center top plate 33, the tray 2 slides on the upper surface of the two side top plates 34.
