Description

Technical Field

[0001] This application relates to the field of molds, and in particular to a metal part assembly gripper assembly and installation method. Background Technology

[0002] In industrial product parts, metal components need to be assembled and fixed into plastic parts to form industrial parts such as connectors and sensor assemblies. Due to the requirements of equipment and functions, these industrial parts have various shapes and cannot be installed using a single universal mounting device. For example, as shown in the attached... Figure 8 and Figure 9 As shown, metal part C needs to be pressed into plastic part D. Due to the special structure of metal part C and its large total length, as well as its relatively thin material thickness, it is very easy for it to bend and deform during assembly by pressing, and even some irreversible plastic deformation may occur, which may lead to damage.

[0003] Therefore, an installation device needs to be designed to enable the crimping assembly of such long, irregularly shaped metal parts. Summary of the Invention

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] To ensure greater accuracy in the full description of this application, all references to directions should be made using the format provided. Figure 2 For reference, the direction of the X-axis is defined as the left-right direction; the direction of the Y-axis is defined as the up-down direction; and the direction of the Z-axis is defined as the front-back direction, with the positive direction of the Z-axis being the back.

[0026] Please refer to the reference. Figures 1 to 7 The image shows a metal part assembly gripper assembly disclosed in this application, comprising a first support platform 1, a support block 3 stacked on the upper surface of the first support platform 1, and a second support platform 2 stacked on the upper surface of the support block 3. The metal part assembly gripper assembly further includes a plurality of in-line positioning pins 41, each of which has a first abutment portion 411 formed at its lower end. The lower edge of the in-line positioning pin 41 is supported on the upper surface of the first support platform 1. The first abutment portion 411 is abutted upwards in a countersunk hole (not shown) formed in the lower surface of the support block 3. The upper end of the in-line positioning pin 41 passes upwards through the support block 3 and the second support platform 2 and protrudes above the upper surface of the second support platform 2.

[0027] The metal part assembly gripper assembly also includes a transverse fixing pin assembly 5. The transverse fixing pin assembly 5 includes a shaped positioning pin 51 and a drive mechanism 52. The shaped positioning pin 51 includes a first arm 511 extending in the left-right direction and a second arm 512 fixed to the first arm 511 and extending in the up-down direction. The first arm 511 passes through the support block 3 in the left-right direction (in other embodiments, the first arm 511 can also be designed to pass through the first support platform 1 in the left-right direction). The drive mechanism 52 is fixed to the first support platform 1. In a preferred embodiment, the drive mechanism 52 is fixed to one side of the first support platform 1 in the left-right direction. The drive shaft of the drive mechanism 52 is fixed to the first arm 511 and drives the shaped positioning pin 51 to move entirely in the left-right direction.

[0028] Furthermore, the second arm 512 extends upward through the bearing block 3 and the second bearing 2. The upper edge of the second arm 512 also forms a hook portion 5121 extending in the left-right direction, which protrudes upward above the upper surface of the second bearing platform 2. When using the metal part assembly gripper assembly of this application, the metal part C is first placed on the second bearing platform 2. Specifically, the metal part C is positioned in the left-right and front-back directions by multiple inline positioning pins 41. Then, the drive mechanism 52 drives the irregular positioning pins 51 to move in the left-right direction via a drive shaft, causing the hook portion 5121 to hook onto the metal part C to position the metal part C in the vertical direction.

[0029] In a preferred embodiment of this application, the first segment arm 511 rests downward against the upper surface of the first support platform 1. The lower surface of the support block 3 has an upwardly recessed clearance hole 30, which penetrates the support block 3 in a left-right direction, through which the first segment arm 511 passes. The second segment arm 512 extends upward in a left-right direction on the side furthest from the drive mechanism 52 (relatively, in the left-right direction, the drive mechanism 52 is located on one side of the support block 3, and the second segment arm 512 is located on the other side of the support block 3). The structural design of the irregularly shaped positioning pin 51 and its positional coordination with the support block 3 and the first support platform 1 make the movement of the irregularly shaped positioning pin 51 more stable and controllable, while also saving space below the first support platform 1.

[0030] Please refer to the reference. Figures 1 to 6As shown in the embodiment of this application, the metal part assembly gripper assembly further includes a stop block 11. The stop block 11 is fixed to the first support platform 1 and located on the other side of the support block 3 in the left-right direction. The stop block 11 is used to stop the transitional displacement of the end of the first segment arm 511 away from the drive mechanism 52 (preventing the first segment arm 511 from transitionally moving in the positive X-axis direction). In this embodiment of the application, the stop block 11 is an independent component assembled onto the first support platform 1. Of course, in other embodiments, the stop block 11 can also be designed as an integral part with the first support platform 1.

[0031] Please refer to the reference. Figures 1 to 6 As shown, the metal part assembly gripper assembly of this application further includes a second support platform drive mechanism 20. The second support platform drive mechanism 20 is fixed to the first support platform 1, and the second support platform drive mechanism 20 has a second support platform drive shaft 201. The second support platform drive shaft 201 can drive the second support platform 2 to move upward. In a preferred embodiment, the second support platform drive mechanism 20 is fixed below the first support platform 1, and the second support platform drive shaft 201 extends upward and passes through the first support platform 1 and the support block 3, and can drive the second support platform 2 to move upward.

[0032] Furthermore, in a preferred embodiment of this application, the metal part assembly gripper assembly further includes a first support platform drive mechanism 61, which has a first support platform drive shaft (not shown). The first support platform drive shaft can drive the first support platform 1 to move in the vertical direction. In a preferred embodiment, the metal part assembly gripper assembly also includes a base support platform 6 and a balance platform 7. The first support platform drive mechanism 61 is fixed below the base support platform 6. The balance platform 7 is located above the upper surface of the base support platform 6. The first support platform drive shaft passes upward through the base support platform 6 and is fixed to the balance platform 7. The first support platform 1 and the balance platform 7 are fixed together by four balance connecting rods 71. Specifically, the upper end of each balance connecting rod 71 is fixed to the first support platform 1, and the lower end of each balance connecting rod 71 is fixed to the balance platform 7. The arrangement of the four balance connecting rods 71 ​​and the balance platform 7 enables the first support platform 1 and all parts supported on the first support platform 1 to move smoothly in the vertical direction as a whole.

[0033] When installing the metal part C onto the plastic part D using the metal part assembly gripper assembly of this application, the metal part C is first placed on the second support platform 2. Specifically, the metal part C is positioned in the left-right and front-back directions by multiple in-line positioning pins 41. Then, the drive mechanism 52 drives the irregular positioning pins 51 to move in the left-right direction via the drive shaft, so that the hook part 5121 hooks onto the metal part C to position the metal part C in the vertical direction. Then, the first support platform drive mechanism 61 drives the balance platform 7 to move upward, and the first support platform 1 is moved synchronously through the four balance linkages 71. The assembly mechanism moves upwards, thereby pressing / inserting the metal part C into the corresponding position of the plastic part D. When the metal part C is pressed / inserted into the plastic part D to a set depth (pre-assembly position), the driving action of the first support platform drive mechanism 61 is paused, and the drive mechanism 52 is activated to drive the transverse fixing pin assembly 5 to move in the left and right direction until the hook part 5121 disengages from the metal part C and the driving action stops. Finally, the second support platform drive mechanism 20 is activated to drive the second support platform 2 to carry the metal part C further upwards until the metal part C is completely pressed / inserted into the plastic part D to complete the assembly action. The metal part assembly gripper assembly of this application can easily achieve the assembly of irregularly shaped metal parts C, and can ensure that the metal part C will not fall off during the assembly process, and will not be damaged by pressure.

[0034] In a preferred embodiment, the upper surface of the second support platform 2 has a contoured structure that matches the shape of the metal part C, so as to ensure that the upper surface of the second support platform 2 fits stably with the metal part C.
