Description

Positioning jig set

Technical Field

The present invention relates to a positioning jig set, and more particularly to a positioning jig set providing a unique reference for positioning a product.

Background

In recent years, with the development of the scientific and technological industry, information products such as electronic devices including notebook computers (notebook computers), tablet computers (tablet computers), and mobile phones (mobile phones) have been widely used in daily life. The electronic devices are more and more diversified in form and function, and the convenience and practicability make the electronic devices more popular, and the requirements for the assembly quality of the electronic devices are also increasing.

The positioning fixture used in the assembling process of the electronic device has great influence on improving the quality of the electronic device. In an electronic device, such as a notebook computer, a conventional positioning fixture is dedicated to a single product, and a limit block is usually added around a carrier for general positioning. When the carrier moves to the base, the carrier is accurately positioned through jacking of the base and fixing of the pushing and supporting unit. Generally, a conventional positioning fixture is provided with two pushing units with stronger rigidity and two pushing units with weaker rigidity, and the pushing units with weaker rigidity push one side of the pushing units with stronger rigidity, so that the notebook computer is fixed to approximately the same position each time.

However, in the conventional positioning jig, the base and the abutting unit are moving parts, and the notebook computer has no real unique reference relative to the base after being positioned. In other words, the conventional positioning jig can only fix the notebook computer to substantially the same position each time the notebook computer is fixed, and in fact, the position where the notebook computer is fixed is slightly different each time. The error affects the assembly precision of the notebook computer, so that the assembly quality of the notebook computer cannot be improved.

In addition, the conventional positioning jig can only be used for notebook computers with similar appearances and sizes, and notebook computers with different appearances and sizes cannot share the same carrier. Therefore, when manufacturing various notebook computers on the same production line, various carriers need to be designed and replaced regularly. The above-mentioned problems make the assembly precision of the notebook computer difficult to promote, and the assembly process of the notebook computer is time-consuming and the production cost is difficult to reduce.

Disclosure of Invention

The invention aims to provide a positioning jig set, which can improve the assembly precision of a notebook computer, save the assembly time of the notebook computer and reduce the production cost.

In order to achieve the above object, the positioning fixture set of the present invention includes a base, a stopper, a carrier, and at least one pushing unit. The stop block is fixed on the base. The carrier is used for being placed on the base and bearing a product, wherein the carrier is provided with a notch and a bearing area, when the carrier is placed on the base, the stop block penetrates through the notch to position the carrier, and the stop block is positioned on the first side outside the bearing area. The at least one pushing unit is arranged on the base, when the carrier is placed on the base, the at least one pushing unit is located on the second side outside the bearing area, the first side and the second side are located on two opposite sides of the bearing area, and the movable portion of the at least one pushing unit is used for pushing a product borne by the carrier towards the stop block.

In an embodiment of the invention, the carrier further has a plurality of stoppers, and the stoppers are located at edges of the carrying region.

In an embodiment of the invention, the positioning fixture set further includes a lifting unit disposed under the base for lifting the base.

In an embodiment of the invention, the carrier further has a plurality of elastic members, and the plurality of elastic members are respectively disposed in the notches for contacting the product.

In an embodiment of the present invention, the stopper includes a plurality of sub-stoppers separated from each other.

In an embodiment of the present invention, the stopper is L-shaped.

In an embodiment of the invention, the at least one pushing unit includes two pushing units, and the movable portions of the two pushing units are respectively used for pushing the product carried by the carrier toward two sides of the L-shaped stopper.

Based on the above, when the positioning jig set of the invention fixes the product each time, since the carrier and the product are positioned on the only basis relative to the base, the positioning accuracy of the positioning jig is higher than that of the conventional positioning jig, so that the assembly accuracy of the product is improved. In addition, the positioning jig can be suitable for products with different appearances and sizes, so that the assembly time of the products is saved, and the production cost can be reduced.

Detailed Description

Fig. 1A is a schematic view illustrating a positioning jig set according to an embodiment of the present invention for fixing a large-sized product. Fig. 1B is a schematic view of the positioning jig set of fig. 1A fixing a small-sized product. Fig. 2 is a schematic view of the carrier of fig. 1A. Fig. 3 is a schematic view of the positioning fixture of fig. 1A. Referring to fig. 1A, fig. 2 and fig. 3, the positioning fixture assembly 100 of the present embodiment includes a base 110, a stopper 120, a carrier 130 and at least one pushing unit 140. In the present embodiment, the product a and the product B are exemplified by a notebook computer, but not limited thereto. In addition, the base 110, the stopper 120 and the at least one pushing unit 140 form a positioning fixture 100A according to an embodiment of the invention.

In this embodiment, the stopper 120 is fixed to the base 110. Further, the stop 120 is a bearing edge of the product a when being positioned, and the position and shape of the stop 120 do not move or change relative to the base 110, so the stop 120 can provide a unique reference of the product a relative to the base 110.

The carrier 130 is used for placing on the base 110 and carrying the product a. Thus, the product a can be safely and stably transported to the base 110 of each positioning jig set 100 in the production line. Carrier 130 has a gap 132 and a carrying area 134. When carrier 130 is placed on base 110, stopper 120 passes through notch 132 to position carrier 130, and stopper 120 is located on first side S1 outside carrying area 134.

In detail, the pair of notches 132 is located at the stopper 120. Accordingly, the notch 132 is also located on the first side S1 outside the bearing area 134. When stopper 120 passes through notch 132, carrier 130 is restricted by the contour of notch 132 to move or rotate, so that carrier 130 is fixed relative to base 110. Overall, the contour of the notch 132 is the same as the contour of the stopper 120, and the contour of the notch 132 may be slightly larger than the contour of the stopper 120, so that the stopper 120 can smoothly pass through the notch 132 and still be limited in movement or rotation by the contour of the notch 132.

At least one pushing unit 140 is disposed on the base 110. When carrier 130 is placed on base 110, at least one pushing unit 140 is located on second side S2 outside carrying area 134. The first side S1 and the second side S2 are located at two opposite sides of the carrying region 134. The movable portion 142 of the pushing unit 140 is used to push the product a carried by the carrier 130 toward the stopper 120. The types and the number of the pushing units 140 can be set or increased or decreased according to actual requirements. For example, the pushing units 140 of the present embodiment are two, and the driving mechanism of the pushing unit 140 is a cylinder, but not limited thereto. The movable portion 142 of the present embodiment is a rectangular flat plate, and in other embodiments, the movable portion may have a different shape, to which the present invention is not limited.

Further, the first side S1 can be regarded as a bearing side, and the stopper 120 for bearing the product a is disposed on the first side S1. The second side S2 can be regarded as a force application side, and the pushing unit 140 for applying force to the product a is disposed on the second side S2. The first side S1 and the second side S2 are located at two opposite sides of the carrying region 134, for example, the carrying region 134 of the embodiment is rectangular, the first side S1 is located outside two adjacent sides of the rectangle, and the second side S2 is located outside two other adjacent sides of the rectangle, so that the first side S1 and the second side S2 are located at two ends separated by a diagonal line of the rectangle and are opposite to each other.

The pushing units 140 and the stoppers 120 of the present embodiment are respectively located on two opposite sides of the carrying region 134, and the pushing units 140 apply force to the movable portion 142 toward the stoppers. Further, each pushing unit 140 may apply a force to each movable portion 142 in a direction not departing from the stopper 120, however, the product a is pushed toward the stopper 120 by the pushing of the movable portions 142 due to the resultant force direction from the movable portions 142 toward the stopper 120, and the final product a is supported by the stopper 120 and is fixed.

In the present embodiment, the stopper 120 includes a plurality of sub-stoppers 122 separated from each other, wherein the respective sub-stoppers 122 can be arranged in different shapes. For example, the two sub-stoppers 122 of the present embodiment are arranged to form an L-shape, which can provide a stable bearing surface for the product a in two directions. In other embodiments, the sub-stops may be arranged in any shape that provides a stable product bearing surface, and the invention is not limited thereto. In addition, the stopper 120 of the present embodiment includes two sub-stoppers 122 separated from each other, and in other embodiments, the stopper may be integrally formed, but the present invention is not limited thereto.

The carrier 130 of the present embodiment further has a plurality of limiting blocks 136, and the limiting blocks 136 are respectively located at the edge of the carrying area 134. In detail, each limiting block 136 is disposed to avoid a moving path of each abutting unit 140, so as to avoid interference between the limiting block 136 and the abutting unit 140, and each abutting unit 140 can abut the product against the stopper 122 without being obstructed. The stoppers 136 are used to limit the movement or rotation of the product a, so as to prevent the product a from being separated from the carrier 130 by external force when the product a is carried by the carrier 130.

On the other hand, the carrier 130 further includes a plurality of elastic members 138 disposed in the gap 132 for contacting the product a. For example, each elastic element 138 is aligned with each recess 124 on the block 120, so as to prevent the elastic elements 138 and the block 120 from interfering with each other when the carrier 130 is placed on the base 110. The resilient member 138 projects slightly beyond the stop 120 toward the bearing region 134. When the product a is pushed by the movable member 142 and moves toward the stop block 120, the elastic member 138 can contact the product a first and reduce the impact generated when the product a is pushed to the stop block 120, thereby preventing the product a from being damaged by an excessive impact force.

In the present embodiment, the positioning fixture set 100 is suitable for fixing products with different sizes. For example, referring to fig. 1A and 1B, the volume and area of the product a shown in fig. 1A is larger than the product B shown in fig. 1B. However, the carrying area 134 of the present embodiment can accommodate the products a and B. As shown in fig. 1A and 1B, the movable portion 142 pushes the products a and B against the stopper 120, and both the products a and B are stably fixed. In other words, the positioning fixture 100A of the present embodiment can fix products with different sizes. In addition, carrier 130 does not need to be replaced when securing different sized products.

The following illustrates the detailed process of fixing the product by the positioning fixture. FIG. 4 is a schematic view of the pedestal of FIG. 1A before jacking. FIG. 5 is a schematic diagram of the pedestal of FIG. 1A after jacking. Referring to fig. 4 and fig. 5 together and referring to fig. 1A, in the present embodiment, the positioning fixture set 100 further includes a lifting unit 150 disposed under the base 110 for lifting the base 110. The positioning fixture 100A may also include a jacking unit 150. In fig. 4, carrier 130 carries product a and is positioned above base 110, and jacking unit 150 has not yet jacked base 110. At this time, carrier 130 can move relative to base 110, and position notch 132 at stop 120.

After the alignment between the notch 132 and the stopper is completed, as shown in fig. 5, the base 110 is pushed by the lifting unit 150 to move toward the carrier 130 and abut against the carrier 130. At this time, the stopper 120 passes through the notch 132, the carrier 130 and the base 110 are positioned, and the carrier 130 and the base 110 cannot move or rotate relatively.

As shown in fig. 1A, after the positioning of the carrier 130 and the base 110 is completed, each movable portion 142 of each pushing unit 140 starts to operate, so that each movable portion 142 moves toward the stopper 120 and pushes against the product a. Finally, the movable portion 142 pushes the product a against the stopper 120 and the movable portion 142 and the stopper 120 fix the product a together. In the above process, when the movable portion 142 pushes the product against the stopper 120 and the movable portion 142 and the stopper 120 fix the product a together, the elastic member 138 is impacted by the product a to retract and absorb a part of the impact force, so as to prevent the product a from being damaged by an excessive impact force. At this time, the product a is fixed to the base 110 by the movable portions 142 and the stopper 120 on a single reference.

Based on the above, in the positioning jig set of the embodiment of the invention, the carrier can be positioned relative to the base, and the product can also be positioned relative to the base. Therefore, the positioning fixture set of the embodiment of the invention can position and fix the carrier and the product relative to the base every time the product is fixed. Compared with the prior art, the positioning jig set of the embodiment of the invention has higher positioning precision, so that the assembly precision of the product is improved. In addition, the carrier and the positioning jig can be suitable for products with different appearances and sizes, so that the assembly time of the products is saved, and the production cost can be reduced.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
