Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a clamping device for capacitor manufacturing. Background Technology

[0002] In capacitor manufacturing, different process stages have fundamentally different requirements for the clamping objects: processes such as shell encapsulation and surface treatment require stable clamping of the capacitor shell, while processes such as lead soldering, shaping, and testing require precise clamping of the leads. However, existing clamping technologies have serious functional limitations. The design logic of traditional clamping devices is entirely centered around a single clamping object. The clamping surface and clamping spacing of shell clamping devices are specifically adapted to the width and outer diameter of the capacitor. The clamping surface is wide and the spacing is large, making it impossible to accurately position and stably clamp small-diameter leads. On the other hand, lead clamping devices are designed to accommodate small leads, with extremely narrow clamping spacing, making them completely incompatible with the size of the capacitor shell. This forces manufacturers to simultaneously purchase or design dedicated shell clamping equipment and dedicated lead clamping equipment to meet the needs of the entire production process, resulting in a severe limitation and exclusivity in the functionality of the equipment. Utility Model Content

[0003] This utility model aims to at least partially solve one of the problems existing in the prior art. To this end, this utility model proposes a clamping device for capacitor production that can integrate the dual functions of shell clamping and pin clamping, avoid equipment idle waste, and reduce procurement and maintenance costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A clamping device for capacitor production includes a fixed base, a clamping arm mounting base disposed on the upper front side of the fixed base, two clamping arms hinged to the clamping arm mounting base, each clamping arm having a clamping part assembly at its front end, a sliding seat slidably disposed on the clamping arm mounting base between the two clamping arms, an intermediate clamping seat disposed on the front side of the sliding seat, the intermediate clamping seat being able to move forward with the sliding seat between the two clamping part assemblies, and a drive mechanism for driving the two clamping arms to swing and clamp on the fixed base.

[0005] In some embodiments, the clamping assembly includes a clamping plate, an extension seat is provided on the clamping plate, a threaded post is provided on the extension seat, a vertical through hole is provided at the front end of the clamping arm, and a locking nut is threadedly connected to the threaded post after passing through the vertical through hole.

[0006] In some embodiments, a first soft rubber pad is provided on the side of the clamping plate away from the extension seat.

[0007] In some embodiments, a sliding groove is provided at the upper end of the clamping arm mounting base for the sliding seat to slide. A front threaded hole and a rear threaded hole are spaced apart at the front and rear of the bottom wall of the sliding groove. A bolt is also provided on the sliding seat. When the bolt is threadedly engaged with the front threaded hole, the intermediate clamping seat is located between the two clamping parts. When the bolt is threadedly engaged with the rear threaded hole, the intermediate clamping seat is away from the two clamping parts.

[0008] In some embodiments, guide ramps are provided on the left and right sides of the front end of the intermediate clamping seat.

[0009] In some embodiments, a second soft rubber pad is provided on both the left and right sides of the intermediate clamping seat.

[0010] In some embodiments, the driving mechanism includes a cylinder mounted on the fixed base, a connecting plate mounted on the piston rod of the cylinder, a V-shaped driving block mounted on the connecting plate, rollers mounted at the rear ends of the two clamping arms, the V-shaped driving block being positioned between the two rollers and capable of pushing the two rollers outwards, and a tension spring connected to the rear ends of the two clamping arms to keep their rear ends in an inwardly contracted position.

[0011] In some embodiments, the cylinder is located at the bottom end of the fixed base, and the piston rod of the cylinder is arranged horizontally to the rear. A guide rod for guiding the connecting plate to move back and forth is provided at the rear end of the fixed base.

[0012] In some embodiments, a linear slide module is further included, wherein a cylinder mounting base is provided on the slide of the linear slide module, and the cylinder is mounted on the cylinder mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The device allows for flexible switching of clamping modes by sliding the sliding base back and forth. When clamping the housing, the middle clamping base slides backward away from the clamping arms, while the two side clamping arms provide a stable clamping distance adapted to the width of the housing. When clamping the pins, the middle clamping base moves forward between the clamping arms, cooperating with the two side clamping arms to form a narrow-pitch clamping structure adapted to the pins. This eliminates the need for separate sets of equipment for housings and pins, solving the problem of idle dedicated equipment in traditional technologies, significantly improving equipment resource utilization, and avoiding resource waste.

[0014] 2. A single device integrates dual functions, eliminating the need for enterprises to purchase or design two separate sets of dedicated clamping devices, which directly reduces equipment costs and significantly lowers the pressure of fixed asset investment. At the same time, only one device needs to be maintained and stored daily, eliminating the need to invest additional manpower and resources in maintaining idle equipment, which greatly reduces operation and maintenance costs and storage space occupation.

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0020] like Figures 1-4 The clamping device for capacitor production shown includes a fixed base 1, a clamping arm mounting base 2 is provided on the upper front side of the fixed base 1, two clamping arms 3 are hinged to the clamping arm mounting base 2, and each clamping arm 3 has a clamping part assembly at its front end. A sliding seat 4 is slidably mounted on the clamping arm mounting base 2 between the two clamping arms 3. An intermediate clamping seat 5 is provided on the front side of the sliding seat 4. The intermediate clamping seat 5 can move forward with the sliding seat 4 to between the two clamping part assemblies. A drive mechanism for driving the two clamping arms 3 to swing and clamp is also provided on the fixed base 1.

[0021] When operating in the casing clamping mode: Based on the dimensions of the capacitor casing 10 to be clamped, the initial opening and closing angles of the two clamping arms 3 are pre-adjusted via the drive mechanism to ensure that the spacing between the clamping components at the front end of the clamping arms is adapted to the width of the casing. Simultaneously, the sliding seat 4 is controlled to drive the intermediate clamping seat 5 to slide backward, moving the intermediate clamping seat 5 away from the two clamping components to avoid interference with the clamping of the casing 10. The capacitor is conveyed between the two clamping arms 3 via the production line conveyor or manually, aligning the axis of the capacitor casing with the clamping center of the two clamping arms 3. The drive mechanism on the fixed base 1 is activated, causing the two clamping arms 3 to swing inward around the hinge point of the clamping arm mounting base 2 until the two clamping components are tightly fitted to both sides of the capacitor casing 10, achieving stable clamping of the casing through symmetrical clamping force on both sides.

[0022] In pin clamping mode: the sliding block 4 slides forward, moving the intermediate clamping block 5 between the two clamping components, creating a clamping space between the front end of the intermediate clamping block 5 and the two clamping components to accommodate the pins. The capacitor with leads is then fed into the clamping area, positioning the two leads between the intermediate clamping block 5 and the two side clamping components, ensuring the pin axes are aligned with the clamping direction. The drive mechanism is activated, causing the two clamping arms 3 to swing inward, bringing the two clamping components closer to the pins on both sides. The intermediate clamping block 5 acts as a central support point, forming a clamping structure with the two side clamping components. Through the coordinated clamping force of the clamping components and the intermediate clamping block, precise and stable clamping of the two pins is achieved.

[0023] This drives the mechanism to uniformly control the swinging and clamping actions of the two clamping arms 3, while the sliding seat 4 independently controls the forward and backward sliding of the intermediate clamping seat 5. The switching between the two modes can be achieved simply by adjusting the stroke of the sliding seat 4, without needing to adjust the core parameters of the drive mechanism, making the operation logic simple.

[0024] In this utility model, the clamping assembly includes a clamping plate 21, an extension seat 22 is provided on the clamping plate 21, a threaded post 23 is provided on the extension seat 22, a vertical through hole is provided at the front end of the clamping arm 3, and a locking nut 25 is threadedly connected to the threaded post 23 after passing through the vertical through hole.

[0025] The clamping plate 21 can rotate freely around the threaded post 23 to adjust the angle, and can be adapted to the width of the capacitor shell 10 or the pin 11 to achieve full fit between the clamping surface and the part to be clamped.

[0026] Furthermore, a first soft rubber pad 31 is provided on the side of the clamping plate 21 away from the extension seat 22. The first soft rubber pad 31 is made of elastic and wear-resistant material (such as silicone or fluororubber) and directly contacts the surface of the capacitor shell 10 or the pin 11. Compared with the traditional rigid clamping surface, it can buffer the clamping impact force through its own elasticity, avoiding scratches or dents on the shell caused by rigid contact, or deformation of the pins and peeling off of the plating.

[0027] See Figure 3 As shown, a sliding groove 41 for sliding seat 4 is provided at the upper end of the clamping arm mounting base 2. A front screw hole 42 and a rear screw hole 43 are spaced apart at the front and rear of the bottom wall of the sliding groove 41. A bolt 44 is also provided on the sliding seat 4. When the bolt 44 is threadedly engaged with the front screw hole 42, the intermediate clamping seat 5 is located between the two clamping parts. When the bolt 44 is threadedly engaged with the rear screw hole 43, the intermediate clamping seat 5 is away from the two clamping parts.

[0028] The adjustment operation is as follows: loosen the bolt 44 on the sliding seat 4 so that the bolt 44 is completely disengaged from the currently mating screw hole, thus releasing the bolt from fixing the sliding seat 4; manually push the sliding seat 4 to slide along the slide groove 41 at the upper end of the clamping arm mounting seat 2; when the sliding seat 4 slides to the corresponding position, the bolt 44 on the sliding seat 4 is coaxially aligned with the screw hole on the bottom wall of the slide groove 41, tighten the bolt 44 so that it is threadedly engaged with the corresponding screw hole 42, and fix the sliding seat 4 in the slide groove 41 by the clamping force of the bolt. At this time, the switching adjustment operation of the shell clamping or pin clamping mode is completed.

[0029] Furthermore, guide slopes 51 are provided on the left and right sides of the front end of the intermediate clamping seat 5; the guide slopes 51 on the left and right sides of the front end of the intermediate clamping seat 5 are symmetrically inclined. In the pin clamping mode, when the capacitor is transported between the two clamping arms 3, the guide slopes 51 can automatically correct the placement deviation of the capacitor through the guiding effect of the inclined surfaces.

[0030] A second soft rubber pad 61 is provided on both the left and right sides of the intermediate clamping seat 5. The second soft rubber pad 61 directly contacts the inner side of the pin 11. It buffers the clamping stress through its own elasticity, avoiding pin compression deformation, breakage, or plating wear and peeling caused by traditional rigid support. Even if the clamping force control is slightly off, the elastic deformation of the soft rubber pad can absorb the excess pressure, significantly reducing the pin damage rate.

[0031] See Figure 1 , Figure 2 As shown, the driving mechanism includes a cylinder 71 mounted on the fixed base 1. A connecting plate 72 is mounted on the piston rod of the cylinder 71. A V-shaped driving block 73 is mounted on the connecting plate 72. Rollers 74 are mounted at the rear ends of the two clamping arms 3. The V-shaped driving block 73 is located between the two rollers 74 and can push the two rollers 74 to open outwards. A tension spring 75 is also connected to the rear ends of the two clamping arms 3 to keep their rear ends in an inwardly contracted shape.

[0032] The cylinder 71 is located at the bottom end of the fixed base 1, and the piston rod of the cylinder 71 is arranged horizontally to the rear. A guide rod 81 is provided at the rear end of the fixed base 1 to guide the connecting plate 72 to move back and forth.

[0033] Specifically, cylinder 71 is fixed to the bottom of fixed base 1, with its piston rod extended horizontally backward, driving connecting plate 72 and V-shaped drive block 73 to the initial position near the rear end of fixed base 1; tension spring 75 is in a naturally contracted state, using tension to keep the rear ends of the two clamping arms 3 retracted inward, and the clamping assembly at the front end of the clamping arms is in an open state; connecting plate 72 is sleeved on guide rod 81, and guide rod 81 forms a forward and backward movement guide constraint on connecting plate 72, waiting for the capacitor to enter the clamping area.

[0034] During clamping operation, the cylinder 71 is activated, and its piston rod retracts, driving the connecting plate 72 to move smoothly forward along the guide rod 81 at the rear end of the fixed seat 1. Simultaneously, the connecting plate 72 drives the V-shaped drive block 73 to move forward. When the inclined surfaces on both sides of the V-shaped drive block 73 contact the rollers 74 at the rear end of the two clamping arms 3, as it continues to move forward, the pushing force of the inclined surfaces causes the two rollers 74 to separate to both sides, thereby driving the two clamping arms 3 to swing outward around the hinge point of the clamping arm mounting seat 2, while the clamping components at the front end close together and clamp the capacitor.

[0035] This utility model also includes a linear slide module 91, on which a cylinder mounting seat 93 is provided, and the cylinder 71 is mounted on the cylinder mounting seat 93.

[0036] Thus, by setting up the linear slide module 91, the clamping device can be driven to move back and forth as a whole, improving the practicality of the equipment.
