Technical Field

[0001] The present application relates to the technical field of vacuum nozzles, and in particular to a universal vacuum nozzle base structure. Background Art

[0002] In the process of semiconductor packaging, the tray needs to be transported and assembled in multiple steps to complete the processing of the workpiece.

[0003] In order to fix the tray for processing, a vacuum chassis is usually used to grab and fix the adsorbable part of the tray, so that the equipment can proceed to the next operation. The vacuum effect generated by the nozzle base can firmly adsorb the tray on the platform surface. In order to achieve the corresponding grabbing effect, the nozzle base needs to be customized according to the number of unit matrix arrangements on the tray, and the corresponding distribution of nozzles is used to accurately adsorb and fix each unit to prevent vacuum leakage.

[0004] However, the distribution of units on the tray varies due to different batches or designs. For example, there will be a slight shift in some local areas, and such shifts often require re-customization, which is very inconvenient. Utility Model Content

[0005] In order to facilitate adaptation to material trays with different layouts, the present application provides a universal vacuum nozzle base structure.

[0007] By adopting the above technical solution, the seat body part will become an adjustable adsorption area, and an adsorption groove is set in the adsorption area. The adjustment block is mainly used to fix the suction nozzle. In the adsorption groove, the adjustment block itself is slidably adjusted along the first direction, and the suction nozzle moves along the second direction on the adjustment block. In this way, the suction nozzle can be relatively adjusted to various positions in the adsorption groove to adapt to different material tray unit positions and be adjusted according to different material trays, which can form convenient adaptation and adjustment.

[0008] Preferably, the adsorption groove is rectangular, wherein the first direction is parallel to one of the side walls, and the second direction is parallel to another adjacent side wall.

[0009] By adopting the above technical solution, specifically, the adjustment movement is performed along two mutually perpendicular side walls in the adsorption groove, so that the suction nozzle can be fixedly adjusted at any position in the adsorption groove in theory.

[0010] Preferably, two slide rails are arranged in parallel along the first direction in the adsorption groove, and both ends of the adjustment block respectively have fixed ends for fixing to the slide rails, and the lower side of the adjustment block and located between the two fixed ends has a positioning portion embedded between the two slide rails.

[0011] By adopting the above technical solution, the positioning part on the adjusting block is used to be clamped between the two slide rails to form a sliding positioning effect, and after sliding to a determined position, the position of the adjusting block is fixed by the fixed end.

[0012] Preferably, the slide rail has a first slide groove along its length direction, the first slide groove has a rectangular sliding block, and the sliding block is provided with a first stud extending out of the slide rail and used for connecting to the fixed end.

[0018] Preferably, both ends of the positioning portion close to the slide rail are provided with elastic pressing members for pressing against the outer wall of the slide rail.

[0019] By adopting the above technical solution, since the positioning portion may be separated from the adsorption groove upward during the adjustment process, the elastic abutting member is used to initially position the position of the positioning portion, thereby forming a good pre-positioning effect.

[0021] By adopting the above technical solution, the spring has an outward force on the clamping column, and the end of the clamping column can act on the outer wall of the slide rail, thereby forming a limiting effect on the adjustment block between the slide rails, but the adjustment block can still be taken out.

In this way, the suction nozzle can be relatively adjusted in various positions in the adsorption groove to adapt to different material tray unit positions. It can be adjusted according to different material trays, which can form a convenient adaptation adjustment;

[0028] 2. The abutting columns arranged at both ends of the positioning part can apply appropriate abutting pressure to the outer wall of the slider, thereby limiting the positioning part during sliding, which is convenient for adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. Example

[0035] A universal vacuum nozzle base structure, referring to Figure 1 , including a seat body 100, one side of the seat body 100 has no less than two adsorption areas, and in this embodiment, three adsorption areas are used as an example, and each adsorption area corresponds to a unit position where the material tray mainly needs to be adsorbed. Specifically, the adsorption area has a concave adsorption groove 110, and in this embodiment, the adsorption groove 110 is rectangular, and an adjustment block 111 that slides along a first direction is arranged in the adsorption groove 110, and a suction nozzle 200 is arranged on the adjustment block 111, and the suction nozzle 200 can slide positionably along a second direction, and the first direction is perpendicular to the second direction.

[0036] Reference Figure 1 , Figure 2 Specifically, in this embodiment, the adsorption groove 110 is a rectangular groove, wherein the first direction is a direction parallel to one of the side walls, and the second direction is a direction parallel to the other side wall, and the two directions correspond to two adjacent side walls. Two slide rails 112 are arranged side by side in the adsorption groove 110 along the first direction, and the two ends of the adjustment block 111 have fixed ends 113 for fixing to the slide rails 112, respectively. The lower side of the adjustment block 111 and located between the two fixed ends 113 has a positioning portion 114 embedded between the two slide rails 112.

[0037] The positioning portion 114 is mainly embedded between the two slide rails 112, and the fixed end 113 is fixed to the slide rail 112 after sliding. Specifically, the slide rail 112 has a first slide groove 120 arranged along the length direction, and the upper side of the first slide groove 120 passes through the slide rail 112, so as to facilitate the fixing of the fixed end 113. The first slide groove 120 has a rectangular slider 121, which can slide in the first slide groove 120 and will be circumferentially limited inside, and the slider 121 is integrally provided with a first stud 122, which extends outward from the upper opening, and correspondingly, the fixed end 113 has a connecting hole 115 for the first stud 122 to pass through, and the first screw block 123 is threadedly connected to the first stud 122. When adjusting the position of the suction nozzle 200 in the first direction, the adjustment block 111 can slide in the first direction through the cooperation of the first stud 122 and the connecting hole 115. After moving to a suitable position, tighten the first screw block 123 so that the slider 121 is pressed against the inner wall to fix the adjustment block 111 in the first direction.

[0038] The adjusting block 111 has an adjusting groove 130 along the second direction, and the suction nozzle 200 has a second screw 131 embedded in the adjusting groove 130 , and the second screw 131 is connected to a second screw block 132 , so as to adjust the position of the suction nozzle 200 in the second direction.

[0039] The implementation principle of Example 1 of the present application is: in the adsorption area, according to the unit arrangement position of the material tray this time, first remove the adjustment block 111, adjust the position of the suction nozzle 200 in the second direction, tighten the second screw block 132, and then place the adjustment block 111 on the first stud 122. At this time, do not tighten the first screw block 123, slide it along the first direction, and then tighten the first screw block 123 to determine the position of the suction nozzle 200 in the adsorption area. Example

[0040] The difference from Example 1 is that, referring to Figure 3 , Figure 4 In this embodiment, elastic abutting members for abutting against the outer wall of the slide rail 112 are provided at both ends of the positioning portion 114 close to the slide rail 112. Specifically, the elastic abutting member includes a spring 140 and a abutting column. A abutting groove 142 for placing the spring 140 is provided at the end of the positioning portion 114. The spring 140 is located in the abutting groove 142, and the abutting column includes a first portion 143 and a second portion 144. The first portion 143 is slidably disposed in the abutting groove 142, and the second portion 144 is used to extend outward and abut against the outer wall of the slide rail 112. A fixing block 145 is threadedly connected to the end of the abutting groove 142, and the second portion 144 will pass through the fixing block 145. The abutting column is located between the fixing block 145 and the spring 140.

[0041] The first part 143 will be limited in the tightening groove 142 by the fixing block 145, and the second part 144 is used for tightening. Since the fixing block 145 in this embodiment is threadedly connected in the tightening groove 142, in order to avoid affecting the spring 140 during the tightening process, in this embodiment, the fixing block 145 is rotatably connected to the end of the first part 143 with a follower block 146.

[0042] At the same time, the end of the second part 144 is set to be cylindrical, and the side wall of the slide rail 112 is also provided with an embedded groove 147 along the first direction, so that when the adjustment block 111 moves along the first direction, the second part 144 can keep the adjustment block 111 unchanged in the vertical direction and will not separate from between the two slide rails 112, but the adjustment block 111 can also be taken out by pressing, forming a good limiting effect only during the adjustment process, which is convenient for overall position adjustment.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
