Description
Technical Field
[0001] This utility model relates to the technical field of IGBT module housing assembly, and in particular to a plug nut device. Background Technology
[0002] In existing technologies, the nut assembly process for IGBT module housings mainly relies on manual operation. Specifically, metal nuts must be manually inserted one by one into the pre-set slots in the IGBT module housing.
[0003] However, this traditional process has many shortcomings. On the one hand, manual operation is extremely inefficient, which severely restricts the overall capacity increase in mass production and fails to meet the ever-growing market demand. On the other hand, manual operation inevitably leads to errors, resulting in defects such as missing nuts. Since these defects are often difficult to detect accurately in later testing, they seriously affect the product yield. Utility Model Content
[0004] In view of the aforementioned problems in the existing GBT module housing assembly, a plug nut device is now intended to be provided.
[0005] The specific technical solution is as follows: A nut-inserting device includes: a base plate, on which a positioning mechanism and two sets of nut-inserting assemblies are mounted; a positioning area is formed on the base plate for placing a GBT module housing with several preset grooves on both sides; the positioning mechanism is used to position the GBT module housing; and the two sets of nut-inserting assemblies are respectively disposed on both sides of the positioning area for inserting several nuts into the several preset grooves on both sides of the GBT module housing. Each of the described plug nut assemblies includes: A nut holder is mounted on the base plate. The side of the nut holder is provided with several pushing slots, which are respectively arranged opposite to several preset slots on one side of the GBT module housing. The longitudinal width of each pushing slot matches the thickness of the nut. The top of the nut holder has several receiving slots, which are respectively connected to the top sidewalls of the pushing slots. Several nuts are stacked longitudinally in each receiving slot. A pusher frame is disposed on the side of the nut frame away from the positioning area. It has several push parts, which are slidably disposed in several push slots. By pushing the pusher frame toward the positioning area, the push parts push several nuts at the connection points between the push slots and the receiving slots outward into several preset slots on the side of the GBT module housing.
[0006] As a further improvement and optimization of this solution, the nut holder includes: A plurality of nut sleeves, each of which is detachably mounted on the base plate, and each of which is provided with a receiving groove and a pushing groove.
[0007] As a further improvement and optimization of this solution, each of the nut sleeves includes a vertical section and a horizontal section. The vertical section is vertically connected to one end of the horizontal section and forms an "L" shape with the horizontal section. The receiving groove is provided on the vertical section and the pushing groove is provided on the horizontal section.
[0008] As a further improvement and optimization of this solution, the top of each horizontal segment has a clearance opening that communicates with the push slot. Several of the aforementioned push parts are respectively connected to the bottom of the pusher frame.
[0009] As a further improvement and optimization of this solution, at least one recessed hole is provided on the bottom inner wall of the push groove below each of the clearance openings, and a fixing bolt that is threadedly connected to the base plate is installed in the recessed hole.
[0010] As a further improvement and optimization of this solution, the inner countersunk hole is an inner countersunk waist-shaped hole, and the long axis of the inner countersunk waist-shaped hole is set along the distribution direction of the plurality of nut sleeves.
[0011] As a further improvement and optimization of this solution, the receiving groove is a rectangular groove.
[0012] As a further improvement and optimization of this solution, the positioning mechanism includes: Four positioning blocks are detachably connected to the four corners of the positioning area. Each of the four positioning blocks has an arc-shaped positioning surface on the side that is close to each other, which is used to position the blocks against the housing of the GBT module.
[0013] As a further improvement and optimization of this solution, each of the positioning blocks is provided with a mounting hole, and each mounting hole is fitted with a fastening bolt that connects to the base plate.
[0014] As a further improvement and optimization of this solution, the mounting hole is an elongated hole and is set along the width direction of the base plate.
[0015] The positive effects of the above technical solution compared with the existing technology are: (1) By setting two sets of nut plug assemblies, the present invention can push multiple bolts into multiple preset slots of the GBT module housing at the same time by pushing the pusher frame. This not only increases work efficiency, but also effectively avoids the phenomenon of nuts being leaked into the preset slots, thus improving the product yield.
[0016] (2) The design of the recessed waist-shaped hole of this utility model provides greater flexibility for adjusting the position of the nut sleeve, and can more accurately align the push groove with the preset groove, further improving the accuracy of nut push, reducing assembly errors, and improving product quality.
[0017] (3) The avoidance opening of this utility model can avoid spatial interference when the pusher is pushed, reduce the design length of the pusher, and facilitate the installation of the nut sleeve.
[0018] (4) In this utility model, the plastic shell is placed in the positioning area, and the positions of the four positioning blocks are adjusted so that the arc-shaped positioning surface of the positioning block abuts against the corner of the plastic shell. Through positioning in four directions, the plastic shell is accurately fixed in the positioning area. The arc-shaped positioning surface can better match the shape of the plastic shell, improving the accuracy and stability of positioning. (5) The design of the elongated hole in this utility model facilitates the adjustment of the position of the positioning block, and can better adapt to plastic shells of different sizes and specifications, thereby improving the versatility and adaptability of the device. By finely adjusting the position of the positioning block, the positioning accuracy can be further improved, ensuring the precision of nut assembly and improving product quality.

[0023] Figure 1 This is a schematic diagram of the structure of a plug nut device according to the present invention; Figure 2 This is a side view of the nut sleeve of a nut plugging device according to the present invention; Figure 3 This is a top view of the nut sleeve of the plug nut device of this utility model, as shown. Figure 1-3The diagram illustrates a preferred embodiment of a nut-inserting device, comprising: a base plate 1, on which a positioning mechanism 2 and two sets of nut-inserting assemblies 3 are mounted; a positioning area 11 is formed on the base plate 1 for placing a GBT module housing with several preset grooves on both sides; the positioning mechanism 2 is used to position the GBT module housing; the two sets of nut-inserting assemblies 3 are respectively disposed on both sides of the positioning area 11 for inserting several nuts into the several preset grooves on both sides of the GBT module housing; each nut-inserting assembly 3 includes: a nut frame 31 and a pusher frame 32; the nut frame 31 is mounted on the base plate 1; several pusher grooves 313 are provided through the side of the nut frame 31, and the several pusher grooves 313 are respectively connected to one side of the GBT module housing. Several preset slots are arranged opposite each other. The longitudinal width of each push slot 313 matches the thickness of the nut. The top of the nut frame 31 has several receiving slots 312. The several receiving slots 312 are respectively connected to the top sidewalls of the several push slots 313. Several nuts are longitudinally stacked in each receiving slot 312. The push frame 32 is located on the side of the nut frame 31 away from the positioning area 11. It has several push parts 33. The several push parts 33 are respectively slidably disposed in the several push slots 313. By pushing the push frame 32 toward the positioning area 11, the several push parts 33 respectively push the several nuts at the connection between the several push slots 313 and the several receiving slots 312 outward into the several preset slots on the side of the GBT module housing.
[0024] Specifically, the GBT module housing is placed in the positioning area 11 of the base plate 1, and the positioning mechanism 2 positions and fixes the plastic housing to ensure that the several push slots 313 are respectively positioned and close to the several preset slots on the GBT module housing. Several nuts are placed vertically in the receiving groove 312 at the top of the nut holder 31. Since the receiving groove 312 is connected to the top side wall of the pushing groove 313, the nuts can fall into the connection between the pushing groove 313 and the receiving groove 312 and wait to be pushed. By pushing the pusher 32 towards the positioning area 11, a plurality of pushers 33 push a plurality of nuts outward into a plurality of preset slots; The pusher 32 is reset, and the nuts in the several receiving slots 312 automatically fall into the several pusher slots 313 under their own gravity to perform the nut-inserting operation of the next GBT module shell.
[0025] In this application, by setting two sets of nut plug assemblies, multiple bolts can be pushed simultaneously into multiple preset slots in the GBT module housing by pushing the pusher 32. This not only increases work efficiency but also effectively avoids the phenomenon of nuts being left in the preset slots, thereby improving product yield.
[0026] Furthermore, as a preferred embodiment, the nut holder 31 includes: a plurality of nut sleeves 311, each nut sleeve 311 being detachably mounted on the base plate 1, and each nut sleeve 311 being provided with a receiving groove 312 and a pushing groove 313.
[0027] Even better, the nut sleeve 311 is detachable and can be easily adjusted and replaced according to different specifications of plastic shells and the number of preset slots, which improves the versatility and adaptability of the device, reduces production costs, and meets diverse production needs.
[0028] Furthermore, as a preferred embodiment, each nut sleeve 311 includes a vertical section 3111 and a horizontal section 3112. The vertical section 3111 is vertically connected to one end of the horizontal section 3112, forming an "L"-shaped structure. A receiving groove 312 is provided on the vertical section 3111, and a pushing groove 313 is provided on the horizontal section 3112. The "L"-shaped nut sleeve 311 utilizes gravity to automatically drop the nut to the pushing position, simplifying the operation process and improving assembly efficiency. Simultaneously, this structure makes the nut storage and pushing process more stable and reliable, reducing the occurrence of nut jamming or misalignment. Furthermore, as a preferred embodiment, the top of each horizontal segment 3112 has a clearance opening 315 communicating with the push groove 313; a plurality of push parts 33 are respectively connected to the bottom of the push frame 32, and the bottom inner wall of the push groove 313 below each clearance opening 315 is provided with at least one inner countersunk hole 314, and a fixing bolt that is threadedly connected to the base plate 1 is installed in the inner countersunk hole 314.
[0029] Specifically, the setting of the clearance 315 can avoid spatial interference when the pusher 32 is pushed, reduce the design length of the pusher 33, and facilitate the installation of the nut sleeve 311.
[0030] Furthermore, as a preferred embodiment, the inner countersunk hole 314 is an inner countersunk waist-shaped hole, and the long axis of the inner countersunk waist-shaped hole is set along the distribution direction of the plurality of nut sleeves 311. The design of the inner countersunk waist-shaped hole provides greater flexibility for the position adjustment of the nut sleeves 311, and can more accurately align the push groove 313 with the preset groove, further improving the accuracy of nut pushing, reducing assembly errors, and improving product quality.
[0031] Furthermore, as a preferred embodiment, the receiving groove 312 is a rectangular groove. The regular shape of the rectangular groove can better accommodate and limit the nut, so that the nut is neatly arranged in the receiving groove 312, which facilitates the smooth falling and pushing of the nut and improves the stability and reliability of the assembly process.
[0032] Furthermore, as a preferred embodiment, the positioning mechanism 2 includes four positioning blocks 21, which are detachably connected to the four corners of the positioning area 11. Each of the four positioning blocks 21 has an arc-shaped positioning surface 212 on its closest side for contact and positioning with the GBT module housing. When the plastic housing is placed in the positioning area 11, the positions of the four positioning blocks 21 are adjusted so that the arc-shaped positioning surfaces 212 of the positioning blocks 21 contact the corners of the plastic housing. Through positioning in four directions, the plastic housing is accurately fixed within the positioning area 11. The arc-shaped positioning surfaces 212 better adapt to the shape of the plastic housing, improving the accuracy and stability of the positioning. Furthermore, as a preferred embodiment, each positioning block 21 is provided with a mounting hole 211, and a fastening bolt connected to the base plate 1 is installed in each mounting hole 211. The design of the mounting hole 211 and the fastening bolt allows the positioning block 21 to be firmly installed on the base plate 1, ensuring that the positioning block 21 will not move during the assembly process, thereby improving the stability of positioning.
[0033] Furthermore, as a preferred embodiment, the mounting hole 211 is an elongated hole, positioned along the width of the base plate 1. This elongated hole design facilitates the adjustment of the positioning block 21's position, better adapting to plastic housings of different sizes and specifications, thus improving the device's versatility and adaptability. By fine-tuning the position of the positioning block 21, the accuracy of positioning can be further improved, ensuring the precision of nut assembly and enhancing product quality.
[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
