[0002] There is an important control module in the inverter, in which the "sandwich-style" assembly of I-type magnetic blocks, PCBA, and E-type magnetic blocks is completed through the bonding process.

[0025] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0026] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0028] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0029] The present application provides a fixture, referring to Figure 1 and Figure 6 , which comprises a pair of mold base plates 1 arranged opposite to each other, and the two mold base plates 1 are used to cooperate with each other to clamp the PCBA board to be processed. Figure 1 , each mold bottom plate 1 is provided with a magnetic block support 2 and a corresponding locking member 3. Among them, the magnetic block support 2 is slidably matched with the mold bottom plate 1, and at least two limit slots 21 for matching with the locking member 3 are provided on the magnetic block support 2. When the locking member 3 is matched with any limit slot 21, the position of the magnetic block support 2 is locked. When the locking member 3 leaves the limit slot 21, the magnetic block support 2 is in a slidable state, so that the position of the magnetic block support 2 can be switched. In the bonding process, the difference between the clamps used for different series of products mainly lies in that the position of the magnetic block support 2 on the clamp has a deviation in a certain direction. For this reason, by setting the magnetic block support 2 to be slidable, the adaptation of different series of products can be completed without changing the tooling fixture. Among them, the spacing between adjacent limit slots 21 can be designed according to the process requirements of different products, and this application does not make specific restrictions.
[0030] Further, see Figures 2 to 6 ,in, Figure 2 and Figure 3A possible shape of the mold base 1 is shown. Figure 4 and Figure 5 Another possible shape of the mold base plate 1 is shown. The mold base plate 1 is provided with a first opening 11 and a second opening 12, respectively, and the first opening 11 and the second opening 12 are connected through a through groove 13. The first magnetic block support 2 and the first opening 11 are slidably matched, and the limit slot 21 is provided on the side of the magnetic block support 2 facing the second opening 12. The locking member 3 is installed in the second opening 12, and is matched with one of the limit slots 21 through the through groove 13.
[0031] Further, see Figures 2 to 5 The first opening 11 may be a trapezoidal opening with steps, and a wear-resistant frame 4 is installed in the first opening 11 by bolts, and the magnetic block support 2 slides in the wear-resistant frame 4. The circumferential side wall of the magnetic block support 2 is provided with a slide bar, and the inner side wall of the wear-resistant frame 4 is provided with a slide groove for cooperating with the slide bar. Through the cooperation of the slide bar and the slide groove, the magnetic block support 2 can move smoothly along the wear-resistant frame 4.
[0032] Further, see Figures 2 to 6 , the locking member 3 can adopt a locking cylinder, which can be a pneumatic cylinder. The cylinder body of the locking member 3 is installed in the second opening 12 through the mounting plate 14, and the telescopic rod of the locking member 3 can extend into the second opening 12 through the through slot 13, and be clamped in one of the limit slots 21, so as to achieve the locking of the magnetic block support 2. When the type of product to be processed needs to be switched, the telescopic rod of the locking member 3 is first controlled to be retracted, and the position of the magnetic block support 2 is adjusted so that the corresponding limit slot 21 is aligned with the through slot 13, and then the telescopic rod of the locking member 3 is controlled to extend and be clamped in the above-mentioned corresponding limit slot 21, so as to achieve the switching of the tooling fixture state.
[0033] Furthermore, in order to meet the requirements of the magnetic support 2 for resisting high and low temperature and thermal cycle shock, the material of the magnetic support 2 can be made of a high temperature resistant alloy, such as high temperature resistant aluminum silicon iron nickel.
[0034] The tooling fixture provided in the embodiment of the present application is equipped with a switchable magnetic support 2 and a matching locking member 3 on the tooling fixture. When the product to be processed needs to be switched, the position of the magnetic support 2 can be directly switched to achieve matching of the tooling fixture without the need to replace the new tooling fixture, thereby reducing material and labor costs and improving processing efficiency.
[0035] Based on the above-mentioned fixture, the embodiment of the present application also discloses a mechanism that facilitates seamless change of fixture. Figure 7, the mechanism includes a position switching component 5, a control terminal and the above-mentioned fixture. The control terminal is respectively connected to the position switching component 5 and the locking member 3 by signals, and is used to control the operation of the position switching component 5 and the locking member 3, so as to realize the automatic switching of the position of the magnetic block support 2 in the fixture, saving manpower. Among them, the position switching component 5 is set one by one corresponding to the mold base plate 1, and is used to drive the corresponding magnetic block support 2 in the mold base plate 1 to slide under the control of the control terminal. When the position switching component 5 drives the magnetic block support 2 to a stopped state, one of the limit slots 21 in the magnetic block support 2 can cooperate with the locking member 3.
[0036] Further, see Figure 7 The position switching component 5 includes a latch cylinder 51 and a mold changing cylinder 52, which are respectively connected to the control terminal by signals, wherein the latch cylinder 51 and the mold changing cylinder 52 can both be air cylinders. The telescopic rod of the mold changing cylinder 52 is arranged along the sliding direction of the magnetic block support 2, and the cylinder body of the latch cylinder 51 can be fixedly connected to the telescopic rod of the mold changing cylinder 52, and the telescopic rod of the latch cylinder 51 is arranged perpendicular to the sliding direction of the magnetic block support 2. The magnetic block support 2 is provided with a slot 22 for cooperating with the telescopic rod of the latch cylinder 51. The slot 22 can be directly opened on the magnetic block support 2, such as Figure 5 It is also possible to connect an extended extension block 6 to the magnetic block support 2, and then open a slot 22 on the extension block 6, as shown in FIG. Figure 2 The specific settings can be made according to production requirements and equipment conditions.
[0037] When switching is required, the control terminal first controls the telescopic rod of the locking cylinder to retract and leave the limit slot 21. Then, the telescopic rod of the change cylinder 52 drives the latch cylinder 51 to move to the current position of the magnetic support 2, so that the telescopic rod of the latch cylinder 51 can be aligned with the slot 22 on the magnetic support 2. After that, the telescopic rod of the latch cylinder 51 extends and clamps in the slot 22, and the change cylinder 52 continues to drive the latch cylinder 51 to move, thereby driving the magnetic support 2 to the target position. At this time, the other limit slot 21 on the magnetic support 2 is just aligned with the telescopic rod of the locking cylinder. Finally, the telescopic rod of the locking cylinder extends and enters the limit slot 21, thereby realizing the switching of the fixture state. Among them, the change cylinder 52 can be installed at a suitable position on the bonding equipment to meet the above-mentioned functional requirements.
[0038] Furthermore, in order to improve the accuracy of the moving position of the mold changing cylinder 52, a displacement sensor 7 may be provided. The displacement sensor 7 signal is connected to the control terminal, and is used to monitor the displacement distance of the telescopic rod of the mold changing cylinder 52. For example, the displacement sensor 7 may be a contact displacement sensor 7, whose contact slider abuts against the telescopic rod of the latch cylinder 51. When the latch cylinder 51 moves with the telescopic rod of the mold changing cylinder 52, the contact slider of the displacement sensor 7 will also be extended and retracted accordingly. At the same time, the displacement sensor 7 will feed back the detected displacement distance to the control terminal in real time, so that the control terminal can control the operation of the mold changing cylinder 52 based on the displacement distance.
[0039] It should be noted that the slidable magnetic block supports 2 and locking members 3 in the same mold base plate 1 can also be provided in multiple groups. In this case, the corresponding latch cylinders 51 and mold changing cylinders 52 in the position switching assembly 5 can also be provided in multiple groups.
[0040] The embodiment of the present application provides a mechanism that facilitates seamless replacement of tooling and fixtures. Through the setting of the position switching component 5 and the control terminal, when the state of the tooling and fixture needs to be switched, the position switching component 5 can be controlled by the control terminal to operate, thereby realizing automatic switching of the position of the magnetic block support 2, which helps to further reduce labor costs and improve processing efficiency.
[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
