[0035] At present, the assembly process of ultra-thin cards is extremely cumbersome. It not only requires employees to hold the product for a long time and stably during the assembly process to perform fine assembly with tweezers, but also requires employees to apply pressure on a small plane for a long time and frequently, and use the tip of the tweezers to squeeze the ultra-thin sheet for assembly. The assembly process is cumbersome, and the requirements for employees are high, making it difficult to ensure the yield of the product. Therefore, the present invention proposes a button assembly jig 100, which can improve work efficiency, increase product yield, and reduce the work intensity of employees.

[0036] Reference below Figures 1 to 5 A key assembly jig 100 according to an embodiment of the present invention is described.

[0037] The button assembly jig 100 of the embodiment of the present invention includes: a limit module and a drive module, the limit module includes a positioning mechanism 120 and a pre-pressing mechanism, the pre-pressing mechanism is movably mounted on the positioning mechanism 120, and the positioning mechanism 120 is used to fix the product; a pressing claw 141 is provided on the driving end of the drive module, and the drive module is used to drive the pressing claw 141 to approach or move away from the pre-pressing mechanism, and the pressing claw 141 approaches the pre-pressing mechanism so that the pre-pressing mechanism presses the button on the product and then highlights the button position. After the positioning mechanism 120 fixes the product, the pressing claw 141, driven by the drive module, applies downward pressure to the pre-pressing mechanism, and applies force to the pre-pressing mechanism so that the pre-pressing mechanism presses the button on the product and then highlights the button position. The setting of this button assembly jig 100 improves product yield, improves work efficiency, and reduces the work intensity of employees.

[0038] It should be noted that the driving module is connected to the air control valve, and the air volume entering the driving module is controlled by the air control valve, so as to drive the pressing claw 141 to approach or move away from the pre-pressing mechanism.

[0039] It should be noted that, refer to Figure 1The driving module is a cylinder 140, and a pressing claw 141 is provided on the driving end of the cylinder 140. After the positioning mechanism 120 fixes the product, the air control valve is opened, and the pressing claw 141, driven by the cylinder 140, applies downward pressure to the pre-pressing mechanism. By applying force to the pre-pressing mechanism, the pre-pressing mechanism presses the button on the product to highlight the button position. At this time, the ultra-thin card installed on the insert pen 200 is aligned with the button position to install the ultra-thin card.

[0040] Reference Figure 4 In some embodiments, the pre-stressing mechanism is provided with at least two screws, and the positioning mechanism 120 is provided with screw adjustment holes corresponding to the screws of the pre-stressing mechanism, and the pre-stressing mechanism is detachably mounted on the positioning mechanism 120 by at least two screws.

[0041] It should be noted that because the pressure exerted by the pre-pressing mechanism on the product buttons is not enough to make the buttons on the product protrude out of the button position, a driving module is provided, and the driving end of the driving module provides sufficient pressure for the pre-pressing mechanism to press the buttons on the product to protrude out of the button position.

[0042] Reference Figure 1 and Figure 5 It can be understood that the button assembly jig 100 further includes a base 110, a first groove 111 is provided on the base 110, a positioning mechanism 120 is provided in the first groove 111, and a driving module is provided on the base 110. The first groove 111 is provided for fixing and limiting the positioning mechanism 120, and the base 110 also supports the driving module and the limiting module.

[0043] In some embodiments, reference Figure 5 A fourth groove 112 is also provided on the base 110, and the driving module is arranged in the fourth groove 112. The fourth groove 112 is used to fix and limit the driving module.

[0044] Reference Figure 2 It can be understood that a limit block 121 and a positioning block 122 are convexly provided on the surface of the positioning mechanism 120, the limit block 121 is a gear-shaped convex portion, the limit block 121 and the positioning block 122 are adjacently arranged, and both the limit block 121 and the positioning block 122 are used to clamp and fix the product.

[0045] It should be noted that the product is annular in shape and is provided with a plurality of different concave and convex structures. The shape and structure of the limit block 121 correspond to the product and are used to fix and limit the product. The positioning block 122 is a triangular convex portion, and the product is clamped and fixed by the limit block 121 and the positioning block 122 to prevent the product from rotating and fix the product.

[0046] Reference Figure 1 and Figure 3It can be understood that a limiting groove 124 is opened on one side of the positioning mechanism 120, and the pre-pressing mechanism includes a pre-pressing plate 130, and the pressing claw 141 is close to the pre-pressing plate 130 so that the pre-pressing plate 130 is clamped in the limiting groove 124.

[0047] It should be noted that the product is fixed on the positioning mechanism 120. At this time, the air control valve has not been opened, and the pressing claw 141 on the driving module is away from the pre-stressing plate 130. The pre-stressing plate 130 is turned to other directions not facing the limiting groove 124, and then the button and the spring are installed in the groove of the product. Then the pre-stressing plate 130 is turned to the direction of the limiting groove 124, and the air control valve is opened. Driven by the driving module, the pressing claw 141 applies downward pressure to the pre-stressing mechanism, and the driving module provides pressure for the pre-stressing mechanism, so that the pre-stressing plate 130 is stuck in the limiting groove 124.

[0048] Reference Figure 3 and Figure 4 It can be understood that the positioning mechanism 120 is further provided with a second groove 126 and a first through hole 125, the second groove 126, the first through hole 125 and the limiting groove 124 are sequentially connected, and the pre-pressing mechanism further includes a rivet 132, one end of which is arranged in the second groove 126, and the other end of which is movably arranged in the first through hole 125 and connected to the pre-pressing plate 130, and one end of the rivet 132 is provided with a chassis. This structural arrangement allows the rivet 132 and the pre-pressing plate 130 to move up and down, so that the pre-pressing plate 130 can press the button on the product.

[0049] It should be noted that, refer to Figure 3 The positioning mechanism 120 is a plate, the second groove 126 and the first through hole 125 are located on the same side of the positioning mechanism 120 , the positioning block and the limiting block are located on the other side of the positioning mechanism 120 , and the limiting groove 124 is located at the top position of the positioning mechanism 120 .

[0050] It should be noted that a second through hole corresponding to the rivet 132 is provided at one end of the pre-compression plate 130, and one end of the rivet 132 is connected to the pre-compression plate 130 by passing through the second through hole; the diameter of the chassis is larger than the diameter of the first through hole 125, and when the chassis moves up and down with the rivet 132, it will maintain a certain distance from the side wall of the second groove 126.

[0051] Reference Figure 1 It can be understood that a pressing block 131 is also provided on the pre-pressing plate 130, and the pressing block 131 is used to press the button on the product to highlight the button position.

[0052] It should be noted that the pressing block 131 and the rivet 132 are respectively located at the two ends of the pre-pressing plate 130, and the pressing block 131 is located at a position corresponding to the button on the product, which is convenient for pressing the button on the product to highlight the button position.

[0053] It is understandable that the pre-pressing mechanism further includes an elastic component, which is disposed in the second groove 126 and sleeved on one end of the pull pin 132; one end of the elastic component is located on the bottom plate of the pull pin 132, and the other end abuts against the side wall of the second groove 126. With this arrangement of the elastic component, when the pre-pressing plate 130 turns to align with the direction of the limiting groove 124, the elastic component exerts a downward pulling force on the pre-pressing plate 130 and the pull pin 132, forcing the pre-pressing mechanism to press downward, so as to press the button on the product, and the button is further pressed to protrude into position under the further pressure of the driving module.

[0054] It should be noted that when the air control valve has not yet opened, the pressing claw 141 on the driving module is away from the pre-stressing plate 130. When the pre-stressing plate 130 is turned to other directions not facing the limiting groove 124, the pre-stressing plate 130 is located at the notch of the limiting groove 124 or above the notch. At this time, the elastic component will be compressed between the chassis of the rivet 132 and the side wall of the second groove 126. Therefore, when the pre-stressing plate 130 is turned to align with the direction of the limiting groove 124, the elastic component will exert a downward pulling force on the pre-stressing plate 130 and the rivet 132. Under the action of the elastic component, the pre-stressing plate 130 moves toward the bottom of the limiting groove 124, forcing the pre-stressing mechanism to press downward so as to press the button on the product and highlight the button position under further pressure from the driving module.

[0055] It can be understood that the elastic component is a linear spring, has a stable and linear dynamic response, and provides elastic force.

[0056] Reference Figure 3 and Figure 4 It can be understood that the positioning mechanism 120 is further provided with a third groove 127, the bottom of the third groove 127 is connected to the first through hole 125, the pre-pressing mechanism further includes a mounting plate 133, the mounting plate 133 is arranged in the third groove 127, the positioning mechanism 120 is detachably connected to the mounting plate 133, and the mounting plate 133 is arranged adjacent to the rivet 132. The mounting plate 133 is used to fix and limit the rivet 132, limit the rivet 132 in the first through hole 125, and prevent the rivet 132 from swinging in the horizontal direction, so that the rivet 132 can only move up and down.

[0057] It should be noted that, refer to Figure 3 The third groove 127 , the second groove 126 and the first through hole 125 are located on the same side of the positioning mechanism 120 , and the second groove 126 , the third groove 127 and the limiting groove 124 are connected in sequence.

[0058] It should be noted that the positioning mechanism 120 is connected to the mounting plate 133 by screws. Figure 4Two screws are provided on the mounting plate 133, and screw adjustment holes corresponding to the two screws are provided on one side of the positioning mechanism 120, and the mounting plate 133 and the positioning mechanism 120 are connected together by the two screws.

[0059] Reference Figure 1 and Figure 4 The limit module further includes at least two brackets 123, one end of each bracket 123 is connected to the side of the positioning mechanism 120 away from the product, the brackets 123 are located on both sides of the driving module, and the other end of the brackets 123 is in the same horizontal plane as one side of the base 110. The brackets 123 and the side of the base 110 in the same horizontal plane play a supporting role.

[0060] It should be noted that first, the base 110 is used as a supporting surface to fix the product on the positioning mechanism 120. After the button and the spring are installed in the groove of the product, the pre-stressing plate 130 is turned to align with the direction of the limiting groove 124, and the air control valve is opened. The pressing claw 141, driven by the driving module, applies downward pressure to the pre-stressing mechanism. By applying pressure to the pre-stressing mechanism, the pre-stressing plate 130 is clamped in the limiting groove 124 and the button on the product is pressed to highlight the button position. After completing the above operations, in order to facilitate the installation of the ultra-thin card, the button assembly jig 100 is turned over so that the two brackets 123 and one side of the base 110 on the same horizontal plane are used as supporting surfaces, and the ultra-thin card is installed on the pen insert 200. The ultra-thin card installed on the pen insert 200 is aligned with the button position, and the assembly can be completed by applying a slight force.
