Detailed Description
To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
As shown in fig. 1 to 3, the printing reflow jig for preventing scratching of a hand in the embodiment includes a supporting plate body 1 and a pressing sheet 2 for pressing a product; the pressing sheet 2 is provided with a window 3 for external equipment to process products; the edge of the pressing sheet 2 is provided with a frame 4; an annular groove 5 for placing the pressing sheet 2 is formed in the supporting plate body 1; and a product placing area 6 for placing products is arranged on the annular groove 5.
Traditional printing backward flow tool, it is on layer board body 1 that it directly places compressing tightly piece 2, then sets up magnetic part 12 through the bottom at layer board body 1 to reach the purpose of holding compressing tightly piece 2. However, the edge of the pressing piece 2 is relatively sharp, so that the hand of an operator is easily cut, and the safety performance is low. Through having set up frame 4, then can avoid the operator to point the sharp edge that direct contact compressed tightly piece 2 to lead to the finger to cut. Through set up on layer board body 1 with the annular groove 5 of frame 4 assembly, can install frame 4 together with compact heap 2 in the exact position fast, be convenient for improve the speed of installation assembly. The utility model discloses can ensure operator's safety, and can not have any negative effects to the technical use, improve operator's operating speed simultaneously, promote production efficiency.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching hand of this embodiment, two sides of the annular groove 5 are provided with grabbing holes 7 extending outwards for facilitating taking the pressing sheet 2.
Specifically, the grasping holes 7 are provided in communication with the annular groove 5, and the perpendicular projection of the grasping holes 7 partially overlaps the perpendicular projection of the annular groove 5. When the operator need take off pressing plate 2 from layer board body 1, only need stretch into earlier the finger and snatch hole 7, then the finger belly of finger just can contact frame 4 naturally, the operator only need with frame 4 together with pressing plate 2 withhold in the lump can afterwards.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching, the frame 4 is provided with a positioning hole 8; a positioning column 9 is arranged on the annular groove 5 corresponding to the positioning hole 8; the positioning column 9 is located in the positioning hole 8.
In order to accurately press the product, the positioning hole 8 is arranged, so that the pressing sheet 2 cannot run out of position in the moving process.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching hand of the embodiment, the number of the positioning holes 8 and the number of the positioning pillars 9 are two; the two positioning holes 8 are respectively positioned at two sides of the frame 4; the two positioning holes 8 are arranged in a staggered manner; the two positioning columns 9 are respectively arranged corresponding to the two positioning holes 8.
Because two locating holes 8 are dislocation set, that is to say that the position of two locating holes 8 is not on same water flat line, so, when the operator mistake will compress tightly piece 2 reverse compress tightly the product, then can be because locating hole 8 on the frame 4 can not normally overlap on the reference column 9 on layer board body 1, then can indicate that the operator is put at present and is turned over, need readjust the direction.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching, the supporting plate body 1 is provided with a direction mark 10.
Through setting up direction identification 10, the operator can distinguish the direction of layer board body 1 fast to with layer board body 1 according to the quick blowing of direction identification 10.
As shown in fig. 1 to 3, in the printing reflow jig for preventing hands from being scratched according to the embodiment, the direction indicator 10 is formed by laser engraving.
If the direction indicator 10 is marked by spraying or the like, the wear resistance is insufficient.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching hand of the embodiment, the bottom of the supporting plate body 1 is provided with a plurality of magnetic grooves 11; each magnetic groove 11 is provided therein with a magnetic member 12.
The magnetic piece 12 is arranged to further prevent the compressing piece 2 from moving because the compressing piece 2 is made of a stainless steel sheet with magnetism. And because magnetic part 12 all sets up in magnetic slot 11, can protect magnetic part 12, avoid being collided with to drop at the in-process that removes layer board body 1.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching hand of the embodiment, an assembling groove 13 for assembling the pressing sheet 2 is formed on the frame 4.
The mode of pressing the groove is adopted, so that the universality is strong, the processing is convenient, the process is simple, and the production cost is low.
As shown in fig. 1 to 3, in the printing reflow jig for preventing scratching, the pressing sheet 2 and the frame 4 are connected by glue.
The glue connection mode is adopted, so that the universality is strong, the processing is convenient, the process is simple, and the production cost is low.
The above is only a preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the protection scope of the present invention.
