Description

Technical Field

[0001] This utility model relates to the field of control circuit board processing equipment technology, and in particular to a moving feeding device for thin film capacitors. Background Technology

[0002] Film capacitors are capacitors constructed by overlapping metal foil as electrodes with plastic films such as polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), or polycarbonate (PC) films at both ends, and then winding them into a cylindrical shape. Depending on the type of plastic film, they are called polyethylene terephthalate capacitors (also known as Mylar capacitors), polypropylene capacitors (also known as PP capacitors), polystyrene capacitors (also known as PS capacitors), and PC capacitors. Film capacitors are mainly used in electronics, home appliances, communications, power, electrified railways, hybrid vehicles, wind power generation, and solar power generation, among other industries. Currently, in some circuit board processing, film capacitors are typically placed in trays and placed in a pre-set section of the circuit board processing area by a feeding device, such as a robotic arm or vacuum nozzle.

[0003] In related technologies, to facilitate loading, multiple trays containing film capacitors are typically stacked below a gripping mechanism. After the gripping mechanism finishes gripping, the empty tray is placed on one side of the loading device, and the tray below is raised to a preset position. The gripping mechanism then continues to grip the film capacitors in the trays, and this process is repeated. In practical applications, when gripping the top tray, the friction between the stacked trays often causes the trays below to move as well. This not only leads to abnormal loading and affects loading efficiency, but the friction can also cause the trays to vibrate and fall, resulting in the film capacitors falling out and being damaged.

[0008] The tray can drive the drive rod to move, and the linkage structure drives the peeling rod to slide out toward the side of the feeding rack, so that the drive rod and the peeling rod respectively abut against the lower surface and upper surface of two adjacent trays, and peel off the two adjacent trays.

[0037] Reference Figures 1 to 8 This utility model proposes a moving feeding device 100 for thin film capacitors.

[0038] In this embodiment of the utility model, the film capacitor moving feeding device 100 includes a frame 10; a lifting mechanism 20 including a driving member and a feeding rack 22, the driving member being mounted on the frame 10, the feeding rack 22 being throttle-connected to the driving member, and multiple trays 200 being stacked on the feeding rack 22; and a separating mechanism 30 including a mounting base 31, a peeling rod 32, a driving rod 33, and a linkage structure 34, the mounting base 31 being mounted on the frame 10 and located above the feeding rack 22, the driving rod 33 being mounted on the mounting base 31, the peeling rod 32 being slidably connected to the mounting base 31 and located below the driving rod 33, and the linkage structure 34 being connected to the driving rod 33 and the peeling rod 32.

[0039] Specifically, the frame 10 is formed by splicing metal profiles, and multiple casters 12 are installed underneath for easy movement. The casters 12 are preferably braked. The driving components of the separation mechanism 30 include a drive motor 211, a drive sprocket 212, a driven sprocket 213, and a transmission chain 214. The drive motor 211 is fixedly mounted on the frame 10. The two drive sprockets 212 and the two driven sprockets 213 are rotatably connected to the frame 10 and are arranged vertically at intervals. The two transmission chains 214 are respectively sleeved on the drive sprockets 212 and the driven sprockets 213. The two drive sprockets 212 are connected to the output shaft of the drive motor 211 through a coupling.

[0040] Two T-shaped sliding guide rails (not shown) are provided in the middle of the frame 10. The sliding guide rails extend along the height direction of the frame 10. A sliding groove (not shown) is provided in the middle of the feeding rack 22 corresponding to the sliding guide rails. One sliding guide rail is embedded in one sliding groove, slidably connecting the feeding rack 22 and the frame 10. The opposite sides of the feeding rack 22 can be fixed to two drive chains 214 with screws. The drive motor 211 rotates, causing the feeding rack 22 to rise or fall relative to the frame 10, raising or lowering the tray 200 to a preset position. The raising or lowering distance can be controlled by a controller, or a sensor can be set at the preset position. Triggering the sensor at the preset position transmits a signal to the control system, which then performs the next action accordingly. This control part is a relatively mature existing technology and will not be described in detail here.

[0041] The working principle of the film capacitor moving feeding device 100 of this application is as follows: multiple trays 200 containing film capacitors are stacked on the feeding rack 22. Driven by the driving component, the feeding rack 22 can move upward toward the frame 10. When it moves to the preset position, the edge of the tray 200 abuts against the driving rod 33, and drives the driving rod 33 to move. The linkage structure 34 connected to the driving rod 33 drives the peeling rod 32 to slide out toward one side of the feeding rack 22. At this time, the driving rod 33 abuts against the lower surface of the uppermost tray 200, and the peeling rod 32 abuts against the upper surface of the lower tray 200. That is, through the interaction of the driving rod 33 and the peeling rod 32, two adjacent trays 200 can be peeled off. This can avoid the situation where the tray 200 below it gets stuck when the gripping mechanism grips the tray 200, and can also avoid the problem of the film capacitor falling out and being damaged, thus further improving the feeding efficiency of film capacitors.

[0042] In this embodiment, the drive rod 33 is rotatably connected to the mounting base 31 via a connecting shaft. The linkage structure 34 includes a first rack 341 and a second rack 342. The first rack 341 and the drive rod 33 are integrally formed, and the second rack 342 is also integrally formed with the peeling rod 32. The first rack 341 and the second rack 342 mesh with each other.

[0043] Please refer to the above. Figures 4 to 6In normal operation, the length of the drive rod 33 extending towards the feeding rack 22 is longer than that of the peeling rod 32. When the tray 200 is lifted upwards, its edge abuts against the end of the drive rod 33, driving it to rotate relative to the mounting base 31. Under the action of the first rack 341 and the second rack 342, the peeling rod 32 extends towards the feeding rack 22 and abuts against the upper surface of the lower tray 200 to prevent it from continuing to move upwards, thereby completing the separation of the two trays 200. After the trays 200 are peeled off, under the action of gravity, the drive rod 33 rotates downwards and returns to its original position, causing the peeling rod 32 to slide away from the feeding rack 22, and so on. In this application, the separation mechanism 30 has a simple structure and can effectively pre-separate the two trays 200 to avoid the gripping mechanism getting stuck when gripping an empty tray 200.

[0044] It should be noted that, in one embodiment, in order to ensure that the drive rod 33 can be reset smoothly, a torsion spring can be provided between the mounting base 31 and the connecting shaft of the drive rod 33, so that the drive rod 33 can be reset smoothly by the elastic force of the torsion spring.

[0045] Please see again Figure 6 and Figure 8 Furthermore, the separation mechanism 30 also includes a limiting protrusion 35, which is integrally machined with the mounting base 31. When the drive rod 33 is reset, that is, when it rotates downward toward the frame 10, the lower surface of the drive rod 33 can abut against the limiting protrusion 35. The limiting protrusion 35 is provided to limit the position of its rotation.

[0046] The peeling rod 32 further includes a rod body 321 and a peeling block 322. The mounting base 31 has a connecting groove, and the edge of the rod body 321 is slidably embedded in this groove. A second rack 342 is disposed on the rod body 321. The end of the rod body 321 away from the mounting base 31 has a mounting groove 321a with a "T"-shaped cross-section, extending along the height direction of the frame 10. The peeling block 322 can abut against the upper surface of the tray 200 and is partially slidably inserted into the mounting groove 321a. Specifically, the peeling rod 32 also includes an adjusting screw. The peeling block 322 has an adjusting threaded hole 322a communicating with the mounting groove 321a. The adjusting screw is screwed into the adjusting threaded hole 322a and abuts against the side wall of the mounting groove 321a. In this application, the peeling block 322 can slide up and down relative to the rod 321, and the two are fixed by adjusting screws. The installation structure is simple, and the position adjustment of the peeling block 322 is more convenient. That is, the position of the peeling block 322 against the upper surface of the tray 200 can be finely adjusted, which can better adapt to the feeding needs of different film capacitors.

[0047] Furthermore, a peeling guide slope 322b is provided on the side of the peeling block 322 facing the feeding rack 22. The peeling guide slope 322b is formed by machining. When the peeling block 322 moves towards the feeding rack 22, the peeling guide slope 322b can abut against the edge of the tray 200. By providing the peeling guide slope 322b, this application can make the peeling block 322 abut against the edge of the tray 200 and make its downward abutting action smoother.

[0048] It should be noted that in this application, two separation mechanisms 30 are provided, located on opposite sides of multiple trays 200. In practice, the trays 200 are usually made of plastic material and are thin-shell shaped with a certain degree of elastic deformation. Therefore, the peeling block 322 is provided with a peeling guide slope 322b, which pushes its edge downward, so that the opening of the tray 200 is in an open state, thus better preventing two adjacent trays 200 from getting stuck.

[0049] Please see again Figure 2 In this embodiment, the film capacitor moving feeding device 100 also includes a feeding cart 40, which is detachably connected to the frame 10 and is provided with a lifting gap 40a; multiple trays 200 can be placed in the feeding cart 40, and the unloading rack 22 passes through the lifting gap 40a to lift the multiple trays 200 away from the feeding cart 40.

[0050] Specifically, the feeding cart 40 is equipped with multiple support rods spaced apart, forming a lifting gap 40a. Correspondingly, the unloading rack 22 includes multiple unloading rods spaced apart. When the feeding cart 40 moves to the bottom of the unloading rack 22, the multiple support rods and multiple unloading rods are arranged in an alternating pattern, and the height of the unloading rods is slightly lower than the height of the support rods. When the unloading rack 22 moves upward, the multiple support rods can lift multiple pallets 200 at once. In this way, the operator can pre-stack multiple pallets 200 outside the operating line and push them to the preset position of the frame 10 for loading, which has higher loading efficiency.

[0051] Furthermore, in this application, the feeding cart 40 is formed by splicing metal profiles, and a magnet 11 is provided on the frame 10. When the feeding cart 40 moves to below the unloading rack 22, the feeding cart 40 and the magnet 11 are magnetically attracted. By providing the magnet 11, it is possible to ensure that the feeding cart 40 can move accurately to the loading position, and it is also possible to prevent the feeding cart 40 from moving during the loading process.

[0052] Furthermore, the frame 10 is equipped with a limiting guide rail 10a, the width of which is the same as or slightly larger than the width of the feeding cart 40. The feeding cart 40 can slide along the limiting guide rail 10a to the bottom of the unloading rack 22. By setting this limiting guide rail 10a, it is convenient for the operator to align the feeding cart 40.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
