Description

Technical Field

[0002] With the development of technology, automobiles have become an indispensable means of transportation for people to travel. Automotive filters are important components of automobiles. Referring to Figure 1 , the automotive filter includes a lower body B, a filter element placed inside the lower body B, and an upper end cover A covering the upper end of the lower body B. A central hole b1 is provided at the center of the lower body B, and a plurality of inner protrusions b2 are arranged on the inner wall of the central hole b1 at equal intervals in the circumferential direction; a plurality of outer protrusions b3 are arranged on the outer circumferential wall of the lower body B at equal intervals in the circumferential direction, and a plurality of lugs b4 are arranged at intervals in the circumferential direction along the upper end of the lower body B.

[0003] Since both the upper end cover A and the lower body B are plastic parts, the existing automotive filters are generally assembled by hot plate welding during assembly. That is, the filter element is first installed inside the lower body B, and then the upper end cover A and the lower body B are held manually. Then, the two components are moved closer to the hot plate. After the hot plate melts and softens the connecting ends of the two components, the upper end cover A and the lower body B are manually pressed together to form an automotive filter. The above assembly process is all completed manually, resulting in high manual labor intensity, low assembly efficiency, uneven assembly quality, and inability to guarantee assembly quality.

This hot plate welding equipment can realize the automatic welding, assembly and detection of automotive filters, with high automation, low labor intensity and high assembly efficiency.

[0052] In some embodiments, as Figure 1 、 Figure 5 and Figure 7 shown, the lower positioning seat 32 includes a central positioning post 321 that can be inserted into the central hole b1. A plurality of positioning grooves 322 adapted to the inner protrusions b2 are annularly and equidistantly arranged on the outer circumferential wall of the central positioning post 321. A receiving cavity 323 for accommodating the lower body B is formed on the outer periphery of the central positioning post 321.

[0054] At the loading station, the upper end cover A and the lower body B can be positioned and installed on the filter fixture 3 by manual loading. When the lower body B is installed, the lower body B is placed in the lower positioning seat 32 from top to bottom; when the upper end cover A is installed, the upper end cover A is placed in the upper positioning seat 31 from bottom to top. In this structure, the upper end cover A and the lower body B are not only accurately positioned to ensure the assembly quality, but also easy to install.

[0055] In some embodiments, Figure 5 and Figure 6 As shown, an upper sensor 33 is installed on one side of the upper positioning seat 31. The upper sensor 33 is used to control the upper clamping block 312 to clamp the upper end cover A after sensing that the upper end cover A is installed; a lower sensor 34 is installed on one side of the lower positioning seat 32. The lower sensor 34 is used to control the lower clamping block 326 to clamp the lower body B after sensing that the lower body B is installed; the upper sensor 33 and the lower sensor 34 are installed on the C-shaped support seat 35 of the filter fixture 3. This structure uses the upper sensor 33 and the lower sensor 34 to control the upper clamping block 312 and the lower clamping block 326, which can realize automatic clamping, reduce human operation, have low labor intensity, and are easy to use. After the mold is closed, the upper clamping block 312 retracts to facilitate the upper end cover A to detach from the upper positioning seat 31, and the final finished product remains on the lower positioning seat 32, which is convenient for the unloading of the unloading component 6.

[0056] like Figure 5 and Figure 6 As shown, two locating pins 313 are arranged diagonally on the upper locating seat 31, and a locating pin hole 327 adapted to the locating pin 313 is provided on the lower locating seat 32; through the cooperation of the locating pin 313 and the locating pin hole 327, the accuracy of the mold closing position of the upper locating seat 31 and the lower locating seat 32 can be guaranteed, and the mold closing effect is good, thereby ensuring the assembly quality of the filter. An upper baffle 314 is provided on the top of the upper locating seat 31, and a lower baffle 328 is provided on the bottom of the lower locating seat 32; at the hot plate station, the upper baffle 314 corresponds to the second upper push rod 43, and the lower baffle 328 corresponds to the second lower push rod 44, which is convenient for pushing the upper locating seat 31 and the lower locating seat 32 toward the hot plate; at the mold closing station, the upper baffle 314 corresponds to the first upper push rod 51, and the lower baffle 328 corresponds to the first lower push rod 52, which is convenient for pushing the upper locating seat 31 and the lower locating seat 32 to close the mold.

[0057] In some embodiments, such as Figure 5 and Figure 6 shown, the filter tooling 3 further includes a C-shaped support seat 35 fixed on the material transfer turntable 2. First guide rods 36 are symmetrically arranged on the C-shaped support seat 35. The two first guide rods 36 are arranged at a vertical interval, and the lower positioning seat 32 is sleeved between the two first guide rods 36; the lifting of the lower positioning seat 32 is guided by the first guide rods, and the movement direction of the lower positioning seat 32 is accurate. A first spring 37 is sleeved on the first guide rod 36, and the first spring 37 always makes the lower positioning seat 32 tend to move downward. Second guide rods 38 are symmetrically arranged on the C-shaped support seat 35. The two second guide rods 38 are arranged at a vertical interval, and the upper positioning seat 31 is sleeved between the two second guide rods 38; the lifting of the upper positioning seat 31 is guided by the second guide rods 38, and the movement direction of the upper positioning seat 31 is accurate. A second spring 39 is sleeved on the second guide rod 38. A tension spring 30 is installed between the C-shaped support seat 35 and the upper positioning seat 31. Both the second spring 39 and the tension spring 30 always make the upper positioning seat 31 tend to move upward; since the upper positioning seat 31 needs to overcome its own gravity when resetting, through the cooperation of the second spring 39 and the tension spring 30, the reliability of the reset function is ensured. With this structure, the cooperation of the C-shaped support seat 35, the first guide rods 36, the second guide rods 38, the upper positioning seat 31 and the lower positioning seat 32 can not only ensure the accurate positioning of the upper end cover A and the lower main body B, but also facilitate the realization of subsequent hot plate functions and mold closing functions. Moreover, the movement directions of the upper positioning seat 31 and the lower positioning seat 32 are accurate, which is beneficial to improving the welding and assembly quality of the product, and the design is ingenious.

[0058] In some embodiments, such as Figure 4 、 Figure 9 and Figure 10 shown, the hot plate assembly 4 further includes a hot plate support seat 42 fixed on the workbench 1. The hot plate 41 is telescopically installed on the hot plate support seat 42, and the telescoping of the hot plate 41 can be driven by a cylinder.

The upper scraper 45 and the lower scraper 46 are used to scrape off the residues on the upper heating core 411 and the lower heating core 412. During the process of the hot plate, the materials of the upper end cap A and the lower main body B may remain on the upper heating core 411 and the lower heating core 412. By adding the upper scraper 45 and the lower scraper 46, during the telescopic process of the hot plate, the residues on the upper heating core 411 and the lower heating core 412 can be scraped off, which is beneficial to ensuring the melting and softening effect.

[0060] In some embodiments, as Figure 11 and Figure 12 shown, the blanking assembly 6 further includes a T-shaped support base 64 fixed on the workbench 1, a horizontal sliding seat 65 slidably installed on the T-shaped support base 64 in the horizontal direction, and a vertical sliding seat 66 liftably installed on the horizontal sliding seat 65.

The dial indicator probe 621 is connected to the lifting plate 622 through a connecting rod 624. The displacement sensor 623 is used to detect the height change of the lifting plate 622. During detection, the dial indicator probe 621 abuts against the upper end of the upper end cap A. The dial indicator probe 621 drives the lifting plate 622 to lift and lower through the connecting rod 624. The displacement sensor 623 is used to detect the height of the lifting plate 622, so as to determine whether the finished product is qualified.

[0062] In some embodiments, as Figure 13 and Figure 14 shown, a plurality of support assemblies 7 for supporting the material transfer turntable 2 are installed on the workbench 1 at intervals in the circumferential direction.

An adjustment screw 73 is installed between the support platform 71 and the height adjustment block 72. By screwing the adjustment screw 73, the height of the height adjustment block 72 can be adjusted. A bearing 74 is installed on the height adjustment block 72, and the bearing 74 is in rolling contact with the bottom of the material transfer turntable 2.

[0063] In some embodiments, as Figure 4 , Figure 9 and Figure 13As shown, the structures of the first upper push rod 51, the first lower push rod 52, the second upper push rod 43 and the second lower push rod 44 are the same, and all adopt a rotating and lifting screw rod.
