Description

Technical Field

[0001] The present invention relates to the technical field of PIN base manufacturing, and in particular to a manufacturing method and an automatic production device for a PIN base with an internal metal washer. Background Art

[0002] Please refer to Figure 1 , in the prior art, a PIN base includes a plastic housing 1, multiple groups of PIN pins 2, multiple metal washers 3, and a metal part 4 for grounding. Among them, the PIN pins 2 are used to achieve electrical connection of external electronic components. The metal washers 3 are annular. The metal washers 3 serve as washers for screws and can make the PIN base stable in a preset position. If the metal washers 3 are not provided during locking and the screws directly contact the plastic housing 1, the screws may become loose when the PIN base is subjected to strong vibration. For example, in the automotive field, as a key component for connecting various electrical components, the PIN base needs to be firmly fixed in a preset position inside the vehicle.

[0003] There are also manufacturing methods and devices for automatically producing PIN bases in the prior art, but they generally have the drawback of low production efficiency. How to find a new way and efficiently manufacture a PIN base with multiple groups of PIN pins 2, multiple groups of metal washers 3, and a metal part 4 for grounding is a technical problem in this field.

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments

[0053] This embodiment provides a manufacturing method for a PIN base with an internal metal washer, including:

[0054] First, please refer to Figure 2 , and perform in-mold injection molding treatment on each group of PIN pins 2 in advance, so as to form a plurality of PIN modules 6 composed of a plastic base 5 and a plurality of PIN pins 2 adhesively bonded to the plastic base 5

[0055] Secondly, configure the PIN module 6 to be placed in the tray in a lying posture. At this time, each tray can store a relatively large number of PIN modules 6, and at a certain height, the number of trays stacked in the vertical direction is also relatively large. At this time, the PIN module 6 can be continuously provided for subsequent automated operations;

[0056] Next, use an automated method to automatically pick up multiple PIN modules 6 from the tray and simultaneously turn the multiple PIN modules 6 by 90° and then place them on the pitch-changing mechanism, so that the multiple PIN modules 6 can be placed on the pitch-changing mechanism with the PIN pins 2 facing downward. Use the pitch-changing mechanism to automatically change the spacing between the multiple PIN modules, so that the relative positions between the multiple PIN modules 6 just meet the actual requirements of the product. At the same time, multiple metal washers 3 have been automatically placed on the transfer table, and a metal part 4 has also been automatically placed on the pitch-changing mechanism or the transfer table;

[0057] Finally, place the multiple metal washers 3, multiple PIN modules 6 and a metal part 4 into the injection molding machine respectively, and let the injection molding machine form the plastic housing 1. At this time, the manufacturing of the PIN base is completed. Finally, take out the formed PIN base from the injection molding machine and place the PIN base at the preset blanking position.

[0058] For the specific implementation of the above manufacturing method of the PIN base, please refer to Figure 3 and Figure 8 simultaneously. This embodiment provides an automatic production device for a PIN base with an internal metal washer, including a frame 10 and a multi-axis manipulator 20, a flipping mechanism 30, a pitch-changing mechanism 40, a vibrating disk 50, a transfer mechanism 60, a transfer table 70, a robot 80, an injection molding machine 90, a blanking mechanism 100 and two feeding mechanisms 110 respectively installed on the frame 10.

[0059] Please refer to Figure 3 and Figure 4 simultaneously. The feeding mechanism 110 is used to output multiple trays stacked in the vertical direction one by one to a preset position, and the feeding mechanism 110 is also used to collect empty trays. The feeding mechanism 110 with this function is a prior art, and its specific structure will not be described in detail. Specifically, the internal material of the tray conveyed by one of the feeding mechanisms 110 is the above-mentioned PIN module 6, and the internal material of the tray conveyed by the other feeding mechanism 110 is the above-mentioned metal part 4.

[0060] Please refer to Figure 3 and Figure 4, The multi-axis manipulator 20 is arranged between two feeding mechanisms 110, so that the multi-axis manipulator 20 can not only quickly pick up the PIN modules 6 in the tray of one feeding mechanism 110, but also quickly pick up the metal parts 4 in the tray of the other feeding mechanism 110. Specifically, the multi-axis manipulator 20 is used to pick up multiple PIN modules 6 on the tray and place the multiple PIN modules 6 on the flipping mechanism 30. The multi-axis manipulator 20 is also used to pick up multiple PIN modules 6 on the flipping mechanism 30 and place the multiple PIN modules 6 on the pitch-changing mechanism 40. The multi-axis manipulator 20 is further used to pick up the metal parts 4 in the tray and place the metal parts 4 on the pitch-changing mechanism 40.

[0061] Please refer to Figure 3 and Figure 5 , The flipping mechanism 30 is used to simultaneously flip multiple PIN modules 6 by 90°, so that the PIN pins 2 in the multiple PIN modules 6 can face downward. Specifically, the flipping mechanism 30 includes a driving mechanism 301, a rotating shaft 302, a bearing seat 303, a power component 304, multiple blocking parts 305 and two support seats 306. The two support seats 306 are fixed on the frame 10. The two end parts of the rotating shaft 302 are respectively installed on the two support seats 306 through bearings, so as to realize that the rotating shaft 302 can rotate freely on the support seats 306. The driving mechanism 301 is connected to the rotating shaft 302 and the frame 10. The driving mechanism 301 drives the rotating shaft 302 to rotate through a gear and rack. The bearing seat 303 is fixedly connected to the rotating shaft 302. The bearing seat 303 has multiple grooves 3031 for receiving the PIN modules 6 in a lying posture. The power component 304 is fixedly connected to the rotating shaft 302. The power component 304 is also connected to multiple blocking parts 305. The number of blocking parts 305 is the same as the number of grooves 3031. The power component 304 is used to simultaneously drive multiple blocking parts 305 to move along Figure 5 the X-axis direction in

[0062] Please refer to Figure 4 and Figure 5, this embodiment further includes a collection box 120 and two detection mechanisms 130. The collection box 120 and the two detection mechanisms 130 are both within the moving range of the above-mentioned multi-axis manipulator 20. One of the detection mechanisms 130 is used to detect the position and front defects of the PIN pins 2 on the PIN module 6, and the other detection mechanism 130 is used to detect the bottom defects of the PIN pins 2 on the PIN module 6. If one of the detection mechanisms 130 detects a defective product, then the multi-axis manipulator 20 will place the unqualified PIN module 6 into the collection box 120, and the multi-axis manipulator 20 will place the qualified PIN module 6 on the pitch-changing mechanism 40.

[0063] Please refer to Figure 3 and Figure 6 , the pitch-changing mechanism 40 includes a base 401, a driving member 402 and at least one row of fixtures 403. The base 401 is fixed on the frame 10, the driving member 402 is fixed on the base 401, and each row of fixtures 403 is arranged in sequence along the Figure 6 Y-axis direction in Figure 7 . Each row of fixtures 403 is slidably connected to the base 401 through a slide rail 404, and the direction of the slide rail 404 is the same as the direction of the Y-axis. The fixture 403 is used to receive a PIN module 6 after being flipped 90°. Moreover, a connecting member 405 is connected between two adjacent fixtures 403 in each row of fixtures 403. Please refer to

[0064] Please refer to Figure 3 and Figure 8 , the vibrating bowl 50 is used to automatically send out the metal washers 3. The transfer mechanism 60 is a combined structure of an existing three-axis transverse movement module and a clamping jaw cylinder. The transfer mechanism 60 is used to transfer the metal washers 3 at the discharge end of the vibrating bowl 50 to the designated position on the turntable 70 one by one. The number of metal washers 3 that can be received on the turntable 70 is the number of metal washers 3 actually required for the PIN socket product.

[0065] Please refer to Figure 3 , Figure 9 and Figure 10, the robot 80 is used to transfer multiple PIN modules 6 and a metal part 4 located on the pitch-changing mechanism 40 into the injection molding machine 90. The robot 80 is also used to transfer multiple metal washers 3 on the turntable 70 into the injection molding machine 90. The robot 80 is further used to take out the molded PIN base from the injection molding machine 90 and place the PIN base at a preset blanking position. Moreover, the flipping mechanism 30, the pitch-changing mechanism 40, the injection molding machine 90, the turntable 70, and the blanking position are arranged in sequence on the outer periphery of the robot 80. More specifically, the robot 80 in this embodiment includes a connected main body 801 and a clamping module 802. The main body 801 is used to drive the clamping module 802 to perform three-dimensional spatial movement, so that the clamping module 802 can clamp specific components at appropriate positions. The clamping module 802 includes multiple first picking parts 8021, a second picking part 8022, multiple third picking parts 8023, and a fourth picking part 8024. The first picking part 8021 is used to pick up the PIN module 6, the second picking part 8022 is used to pick up the metal part 4, the third picking part 8023 is used to pick up the metal washer 3, and the fourth picking part 8024 is used to pick up the PIN base completed by injection molding inside the injection molding machine 90.

[0066] Please refer to again Figure 3 , the injection molding machine 90 includes a rotating table 901, a set of upper molds 902, and two sets of lower molds 903. The rotating table 901 is used to drive the two sets of lower molds 903 to rotate 180°, so that the positions of the two sets of lower molds 903 can be switched with each other. The lower mold 903 is used to receive multiple PIN modules 6, a metal part 4, and multiple metal washers 3 on the robot 80. The upper mold 902 is used to jointly mold the plastic frame 1 in the background art with one set of lower molds 903. Moreover, the upper mold 902 is arranged at a position far from the robot 80, so that during the co-injection molding process of the upper mold 902 and one set of lower molds 903, the robot 80 can simultaneously place the PIN base 6, the metal washer 3, and the metal sheet 4 on the other set of lower molds 903.

[0067] Assume that the PIN base includes K PIN modules 6, where K is greater than or equal to 2 and K is an even number. The K PIN modules 6 are divided into two rows on the PIN base. The maximum number of PIN modules 6 that the pitch-changing mechanism 40 and the robot 80 can receive is K, while the maximum number of PIN modules 6 that the multi-axis manipulator 20 and the flipping mechanism 30 can receive is preferably K / 2. Specifically, please refer to together Figure 1 and Figure 2, the PIN base of this embodiment includes eight PIN modules 6. The maximum number of PIN modules 6 that the pitch-changing mechanism 40 and the robot 80 can receive is eight. At this time, the robot 80 can put all the PIN modules 6 into the injection molding machine 90 at one time, while the maximum number of PIN modules 6 that the multi-axis manipulator 20 and the flipping mechanism 30 can receive is four. In other words, there are two rows of fixtures 403 in the pitch-changing mechanism 40, and the number of fixtures 403 in each row is four, while the number of grooves 3031 in the flipping mechanism 30 is four.

[0068] Please refer to Figure 3 , Figure 4 and Figure 8 , the working principle of the automatic production equipment for the PIN base with built-in metal washers in this embodiment can be referred to the following two paragraphs:

[0069] First, the multi-axis manipulator 20 places four PIN modules 6 in a lying posture from the tray onto the flipping mechanism 30. The flipping mechanism 30 flips the four PIN modules 6 by 90°, making the PIN pins 2 of the four PIN modules 6 face downward. Then the multi-axis manipulator 20 places the four PIN modules 6 after being flipped by 90° onto the pitch-changing mechanism 40. The above is repeated once, so that there are eight PIN modules 6 on the pitch-changing mechanism 40. The multi-axis manipulator 20 also places a metal part 4 from the tray onto the pitch-changing mechanism 40. The pitch-changing mechanism 40 automatically changes the spacing between multiple PIN modules 6 so that the spacing between multiple PIN modules 6 is the actual required for the actual PIN base product. During the above action process, the transfer mechanism 60 places eight metal washers 3 onto the transfer table 70 one by one each time. In addition, at the same time, the upper mold 902 and one set of lower molds 903 are performing injection molding operations, and the robot 80 places the just-molded PIN base from the injection molding machine 90 onto the preset blanking mechanism 100, and the blanking mechanism 100 is used to convey the finished PIN base to a predetermined position;

[0070] Next, when feeding the injection molding machine 90, the robot 80 first picks up all the metal washers 3 from the transfer table 70 at one time, then the robot 80 picks up all the PIN modules 6 and a metal part 4 from the pitch-changing mechanism 40. Immediately after that, after the robot 80 takes out the just-molded PIN base from the injection molding machine 90, it places multiple metal washers 3, multiple PIN modules 6, and a metal part 4 into the corresponding lower mold 903. Finally, the injection molding machine 90 injects and molds the plastic frame 1 in the background technology to form a finished PIN base. During actual operation, the above two paragraphs of action descriptions are cycled in sequence.

[0071] Please refer to Figure 3 and Figure 8This embodiment also includes a detection device (not shown in the figure) connected to the frame 10, a coding mechanism 140, a scanning mechanism 150, a conveying mechanism 160, a finished product receiving mechanism 170 and a defective product receiving mechanism 180. Among them, the detection device is used to perform quality inspection on the PIN seat received by the unloading mechanism 100, the coding mechanism 140 and the code scanning mechanism 150 are both located at adjacent positions of the unloading mechanism 100, and the coding mechanism 140 and the detection device are signal connected. If the detection device detects that the quality of the PIN seat is qualified, the coding mechanism 140 will code the qualified PIN seat. If the detection device detects that the quality of the PIN seat is unqualified, the coding mechanism 140 will not code the unqualified PIN seat. The code scanning mechanism 150 is used to identify whether the PIN seat has been coded. If the code scanning mechanism 150 identifies that the PIN seat has been coded, the conveying mechanism 160 transfers the coded PIN seat from the unloading mechanism 100 to the finished product receiving mechanism 170. If the code scanning mechanism 150 identifies that the PIN seat has not been coded, the conveying mechanism 160 transfers the uncoded PIN seat from the unloading mechanism 100 to the defective product receiving mechanism 180, thereby completing the automatic detection of the PIN seat and the automatic quality screening operation.

[0072] In summary, this embodiment not only bypasses the existing manufacturing method and production equipment, but also can realize the production of the PIN socket in a more efficient manner.

[0073] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementations of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
