Description

Technical Field

[0001] The present invention belongs to the technical field of capacitors, and particularly relates to a gold spraying clamping device for metallized film capacitor elements. Background Art

[0002] In the manufacturing process of metallized film capacitor elements, the gold spraying process is one of the key steps to ensure their performance and durability.

[0003] In the prior art, the patent application with the authorization announcement number CN218521327U discloses a gold spraying clamping device for metallized film capacitor elements, which includes a fixture rectangular frame arranged in a fixture positioning frame. A push rod hole is provided at the front end of the fixture rectangular frame. One end of a fixture frame push rod passes through the push rod hole, and a clamping cross bar is fixed at one end of the fixture frame push rod. The clamping cross bar is located inside the fixture rectangular frame. A top cap is provided at the other end of the fixture frame push rod, which can perform batch gold spraying operations on metallized film capacitor elements and improve the efficiency of the gold spraying operation for metallized film capacitor elements.

[0004] However, in the above technical solution, adjacent capacitor elements rely on mutual extrusion to maintain their positions. Direct extrusion may cause the capacitor elements to deform or be damaged due to excessive pressure. Especially in the case of uneven clamping force, it is easy to cause element rupture or other physical damages. Moreover, for cylindrical capacitor elements, if they rely on mutual extrusion to maintain their positions, displacement or tilt may occur between the elements during the clamping process due to the small contact area, affecting the clamping stability. Summary of the Invention

[0019] As a preference of the above technical solution, a latch is movably arranged on the connecting frame through a spring. A pin hole is arranged on the connecting block. The latch is inserted and matched with the pin hole.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The present invention ensures the precise and stable position of each capacitor element within the fixed frame through the positioning grooves on the bottom support plate and the arc-shaped limiting grooves II on both sides of the partition frame, which can effectively prevent the displacement or tilt of capacitor elements caused by mutual extrusion, and also effectively reduce the risk of element deformation or damage caused by mutual extrusion.

[0035] Embodiment

[0036] As Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 shown, Figure 1 The figure shows a front view schematic diagram of the overall clamping device in the embodiment; Figure 2 The figure shows a top view schematic diagram of the overall clamping device in the embodiment;

[0037] Figure 5 The figure shows a top view schematic diagram of the bottom support plate in the embodiment; Figure 6 The figure shows a top view schematic diagram of the partition frame in the embodiment; Figure 7 The figure shows a top view schematic diagram of the pressing member in the embodiment;

[0038] This device includes:

[0039] A fixed frame 10, with one side of the fixed frame 10 open;

[0040] A bottom support plate 20, detachably arranged at the bottom of the fixed frame 10, and a plurality of positioning grooves 21 are arranged on the end face of the bottom support plate 20 close to the fixed frame 10;

[0041] A partition frame 30, a plurality of partition frames 30 arranged movably are closely arranged inside the fixed frame 10, and arc-shaped second limiting grooves 31 are symmetrically arranged on both sides of the partition frame 30;

[0042] A pressing member 40, detachably arranged at the open end of the fixed frame 10, and a pressing plate 43 is telescopically arranged at one end of the pressing member 40 close to the partition frame 30;

[0043] After the bottom support plate 20 is installed at the bottom of the fixed frame 10, it is installed in the inner side of the fixed frame 10 in the form of a row of capacitor elements and a partition frame 30 in sequence. The adjacent ends of the partition frames 30 that are close to each other are abutted against and tightly held a row of capacitor elements in the middle thereof, and the bottom of the capacitor element is embedded in the positioning groove 21 at the corresponding position. The pressing member 40 is installed at the open end of the fixed frame 10, and its pressing plate 43 is close to and presses multiple rows of partition frames 30 and capacitor elements inside the fixed frame 10. After clamping, the bottom support plate 20 is removed, so that both end faces of the capacitor element are exposed.

[0044] The fixed frame 10 is the basic frame of the entire clamping device. One side of it is open for facilitating the installation of the partition frame 30. Before installing the capacitor element 1, the bottom support plate 20 is first installed at the bottom end of the fixed frame 10. At this time, the bottom support plate 20 plays a main supporting role. Then, the installation of the first row of capacitor elements 1 is started from the end far away from the opening inside the fixed frame 10. When installing, the bottom ends of the capacitor elements 1 are aligned with the positioning grooves 21 of the bottom support plate 20 one by one. After a row of capacitor elements 1 is installed, the partition frame 30 is installed. The arc-shaped limiting groove II 31 provided on the partition frame 30 matches the arc shape of each capacitor element 1. After it is attached to the capacitor element 1, it can effectively hold and fix the capacitor element 1. After multiple rows of capacitor elements 1 and partition frames 30 are installed at intervals, finally, the pressing member 40 is installed at the open end of the fixed frame 10. The pressing plate 43 of the pressing member 40 applies pressure to the multiple rows of partition frames 30 and capacitor elements inside, realizing the overall firm clamping. After the clamping is completed, the bottom support plate 20 can be removed, so that both end faces of the capacitor element 1 are exposed, so as to facilitate the subsequent gold spraying treatment.

[0045] Through the support provided by the bottom support plate 20 from the bottom, the clamping from the side by the partition frame 30, and the combined action of the positioning groove 21 on the bottom support plate 20 and the arc-shaped limiting groove II 31 on both sides of the partition frame 30, it is ensured that the position of each capacitor element 1 in the fixed frame 10 is accurate and stable. This not only improves the accuracy of component installation, but also forms a stable fixing system.

[0046] The bottom support plate 20, the partition frame 30 and the pressing member 40 all adopt a detachable modular design, which is convenient for quick replacement and adjustment, and can also be flexibly adjusted according to capacitor elements 1 of different specifications and sizes, enhancing the versatility of the device.

[0047] After the clamping is completed, the bottom support plate 20 is removed, so that both end faces of the capacitor element 1 are completely exposed, which is beneficial to the subsequent gold spraying treatment, ensures that the gold spraying layer is evenly covered, and improves the quality and performance of the final product.

[0048] Furthermore, an elastic buffer pad is provided on the inner wall of the arc-shaped limiting groove II 31 on the partition frame 30. The elastic buffer pad can play a role in anti-slip and buffering, avoid re-damaging the capacitor element 1 due to extrusion, and can increase the friction force between it and the capacitor element 1, thereby increasing the clamping stability.

[0049] As Figure 4 shown, Figure 4 Figure 7 shows a schematic cross-sectional view of the fixed frame in the embodiment;

[0050] A sliding groove 11 communicating with its open end is formed on the frame body of the fixed frame 10. Sliders 32 are provided at both ends of the partition frame 30, and the sliders 32 of the partition frame 30 are slidably matched with the sliding groove 11 of the fixed frame 10.

[0051] The setting of the sliding groove 11 provides an installation and movement track for the partition frame 30, ensuring that the partition frame 30 can be smoothly adjusted or fixed inside the fixed frame 10. The slider 32 and the sliding groove 11 on the fixed frame 10 form a sliding fit. In this way, the partition frame 30 can be accurately positioned and stably placed along the sliding groove 11, and at the same time, it is also convenient to add or remove the capacitor element 1 as needed.

[0052] An arc-shaped row of limiting grooves I 12 is provided at one end of the frame body of the fixed frame 10 away from its opening.

[0053] Through the provided limiting grooves I 12, a limiting effect is exerted on the first row of capacitor elements 1 installed inside the fixed frame 10. The limiting grooves I 12 and the adjacent partition frame 30 jointly clamp the first row of capacitor elements 1.

[0054] As Figure 7 , Figure 8 shown, Figure 7 Figure 8 shows a top view of the pressing member in the embodiment; Figure 8 Figure 9 shows a cross-sectional view of the pressing member in the embodiment;

[0055] The pressing member 40 includes a base block 41 and a base plate 42. An electric telescopic rod 45 is embedded in the base block 41, and the output end of the electric telescopic rod 45 faces the inside of the fixed frame 10 and is fixedly connected to a pressing plate 43.

[0056] The base block 41 is the core part of the pressing member 40. The embedded electric telescopic rod 45 can provide power to move the pressing plate 43 towards or away from the capacitor element 1 inside the fixed frame 10, thereby realizing automatic pressing and releasing operations.

[0057] A hook 44 is further provided at one end of the base plate 42 away from the base block 41.

[0058] After the overall device is clamped, the overall device can be suspended through the hook 44 to spray paint on the capacitor element 1.

[0059] An extension part 13 is also provided at the open end of the fixed frame 10. Bolt holes 46 corresponding in position are provided on the substrate 42 and the extension part 13, and a locking bolt 47 is movably inserted into the bolt hole 46 to connect the fixed frame 10 and the pressing member 40.

[0060] Through the provided extension part 13, bolt holes 46 and locking bolt 47, a detachable connection between the pressing member 40 and the fixed frame 10 is realized.

[0061] Such as Figure 4 、 Figure 9 、 Figure 10 shown, Figure 4 The figure shows a cross-sectional schematic view of the fixed frame in the embodiment; Figure 9 The figure shows an overall cross-sectional schematic view of the clamping device in the embodiment; Figure 10 The figure shows Figure 9 a magnified schematic view of the structure at A in

[0062] Connection frames 14 are also provided on both sides of the fixed frame 10. A receiving groove 15 is provided on one side of the connection frame 14 close to the bottom support plate 20. A connection block 22 is provided at a position corresponding to the receiving groove 15 on the bottom support plate 20, and the connection block 22 is in plug-in fit with the receiving groove 15.

[0063] A latch 16 is also movably provided on the connection frame 14 through a spring 17. A pin hole is provided on the connection block 22, and the latch 16 is in plug-in fit with the pin hole.

[0064] The connection block 22 located at the position corresponding to the receiving groove 15 on the bottom support plate 20 forms a plug-in fit with the receiving groove 15, which ensures that the bottom support plate 20 can be stably installed at the bottom of the fixed frame 10 and can be quickly aligned and installed;

[0065] Through the coordinated action of the connection frame 14, receiving groove 15, connection block 22 and latch 16, a detachable connection between the fixed frame 10 and the bottom support plate 20 is realized.

[0066] Before the connection block 22 is inserted into the receiving groove 15, the latch 16 can be pulled outward by an external force, so that the connection block 22 can enter the receiving groove 15. After entering, when the external force is removed, the latch 16 will automatically spring into the pin hole on the connection block 22 under the action of the spring, thus realizing the locking function.

[0067] Working principle: When this device is in use:

[0068] ①Install the bottom support plate 20: Insert the bottom support plate 20 into the receiving grooves 15 of the connecting frames 14 on both sides of the fixed frame 10 through the connecting blocks 22 thereon. Before insertion, manually pull the latch 16 to stretch the spring 17 so that the connecting block 22 can smoothly enter the receiving groove 15. Subsequently, remove the external force, and the latch 16 will automatically spring into the pin hole on the connecting block 22 under the action of the spring to complete the locking;

[0069] ②Install the capacitor elements 1 and the partition frame 30: Place the first row of capacitor elements 1. Starting from the end of the fixed frame 10 far from the opening, embed the bottom of the capacitor element 1 into the positioning groove 21 of the bottom support plate 20 and ensure its correct and stable position. Here, the first limiting groove 12 plays a preliminary limiting role for the capacitor elements. Then install the partition frame 30. Install the partition frame 30 behind the first row of capacitor elements 1 so that the arc-shaped second limiting grooves 31 on both sides thereof are in contact with and hold the arc surface of the capacitor element 1, providing additional stable support for the capacitor element 1;

[0070] ③Repeat steps 2 and 3: Continue to install the subsequent capacitor elements 1 and the partition frame 30 according to the above steps until the required quantity is reached;

[0071] ④Install the pressing member 40: After all the capacitor elements and the partition frame 30 are installed, install the pressing member 40 at the opening end of the fixed frame 10. The substrate 42 and the extension part 13 are fixed through the bolt holes 46 and the locking bolts 47. Then, start the electric telescopic rod 45 in the base block 41 to move the pressing plate 43 inward to press all the capacitor elements and the partition frame 30 to ensure that they are closely arranged and stable;

[0072] ⑤Remove the bottom support plate 20: After the above steps are completed, the bottom support plate 20 can be removed (unlock the latch 16 and take out the bottom support plate 20) so that the two end faces of the capacitor element 1 are exposed, ready for gold spraying treatment.

[0073] ⑥Suspend the device for gold spraying: Using the hook 44 provided on the substrate 42 of the pressing member 40, the entire device can be suspended to facilitate the simultaneous gold spraying treatment of the two end faces of the capacitor element 1.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
