Description

Technical Field

[0001] The present invention relates to the technical field of capacitor production, and particularly to a surface inkjet coding device for capacitor production. Background Technique

[0002] A capacitor is composed of a layer of insulating dielectric sandwiched between two metal electrodes. When a voltage is applied between the two metal electrodes, charges will be stored on the electrodes. Therefore, a capacitor is an energy storage element. Any two conductors that are insulated from each other and close to each other form a capacitor. A parallel plate capacitor consists of the plates and dielectric of the capacitor. At the same time, when a capacitor is produced, it is necessary to perform marking and inkjet coding on its outer shell to facilitate users to quickly read information subsequently.

[0003] However, capacitor manufacturers often produce capacitors of different specifications, and capacitors have different shapes and sizes. Existing surface inkjet coding devices for capacitors can only fix capacitors of specified shapes and sizes. In order to perform inkjet coding on different capacitors, enterprises usually have to develop a variety of different fixtures to adapt to the inkjet coding device, increasing production costs. In view of this, we propose a surface inkjet coding device for capacitor production. Summary of the Invention

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , a technical solution provided by the present invention:

[0028] A surface inkjet coding device for capacitor production, including a base 1, two belt rollers are rotatably installed on the base 1, a conveyor belt 2 is drivingly connected between the two belt rollers, the conveyor belt 2 is used for conveying capacitors, a motor is fixedly installed on the base 1, and the output end of the motor is connected to one of the belt rollers for providing power for the movement of the conveyor belt 2 to realize the conveyance of capacitors.

[0029] Most capacitors are cylindrical structures. In order to prevent the capacitors from rolling randomly on the conveyor belt 2, a plurality of limiting mechanisms 3 for limiting the capacitors are provided on the conveyor belt 2, and the plurality of limiting mechanisms 3 are equidistantly distributed around the conveyor belt 2 to facilitate the conveyor belt 2 to convey a plurality of capacitors at one time.

[0030] Specifically, each limiting mechanism 3 includes two positioning bars 31. The bottom end of the positioning bar 31 is fixedly connected to the outer surface of the conveyor belt 2. There is a certain distance between the two positioning bars 31. During use, the capacitor is placed between the two positioning bars 31, and the two positioning bars 31 can stop both sides of the capacitor to prevent the capacitor from rolling randomly on the conveyor belt 2. In addition, since there are multiple limiting mechanisms 3 evenly distributed at equal distances on the conveyor belt 2, during the conveying process, the spacing between the capacitors can be controlled within a certain range, facilitating subsequent operations. The positioning bar 31 is made of a flexible material, such as rubber or silica gel, to adapt to the shape change of the conveyor belt 2 during operation, making the connection between the positioning bar 31 and the conveyor belt 2 tighter. A connection frame 32 is fixedly sleeved on the top of the positioning bar 31. The top of the connection frame 32 is detachably connected with an installation block 33. The connection frame 32 is made of a rigid material, which is convenient for docking with the installation block 33. Limiting plates 34 are fixedly connected to one side of the two installation blocks 33 facing each other. The limiting plates 34 are used to limit the end of the capacitor with pins.

[0031] Please refer to Figure 4 , a plurality of first convex blocks 35 are fixedly connected to the top of the connection frame 32. The plurality of first convex blocks 35 are evenly distributed in a line along the length direction of the connection frame 32. There is a certain distance between the first convex blocks 35, forming a groove-like shape between the two first convex blocks 35. A second convex block 36 is fixedly connected to the bottom of the installation block 33. The second convex block 36 can be inserted between the first convex blocks 35, and after insertion, the first convex block 36 and the second convex block 35 are closely attached to improve the stability of the installation block 33 on the connection frame 32. The first convex block 35 and the second convex block 36 are magnetically connected, and the magnetic connection further improves the tightness of the connection between the installation block 33 and the connection frame 32, preventing the installation block 33 from falling off the connection frame 32. At the same time, it is also convenient to disassemble the installation block 33 and the limiting plate 34, so that the position of the limiting plate 34 on the connection frame 32 can be adjusted according to the different sizes of the capacitors, so that the limiting plate 34 cooperates with the centering positioning mechanism 6 to achieve the centering effect of the capacitor. Further, a mark 37 is provided on the top of the first convex block 35 to improve the convenience of adjusting the position of the installation block 33.

[0032] In this embodiment, a support frame 4 is fixedly connected to the base 1. A coding mechanism 5 and a centering positioning mechanism 6 are respectively arranged on the support frame 4. Among them, the coding mechanism 5 is used to code the surface of the capacitor, and the centering positioning mechanism 6 is used to center and limit the capacitor to ensure the stability of the capacitor during coding and the accuracy of the coding position.

[0033] Specifically, the inkjet mechanism 5 includes a connecting frame 51, the connecting frame 51 is fixedly connected to the support frame 4, a moving component 52 is connected to the connecting frame 51, and an inkjet head 53 is connected to the moving component 52. It should be noted that the moving component 52 is used to control the inkjet head 53 to move horizontally in a specified direction, which may include moving up and down, or moving in both the up and down and front and back directions.

[0034] In this embodiment, the centering and positioning mechanism 6 includes an electric push rod 61, the electric push rod 61 is fixedly installed at the top of the support frame 4, the electric push rod 61 is vertically arranged and the output end faces downward, the output end of the electric push rod 61 penetrates through the support frame 4 and is fixedly connected to a support plate 62, and a trapezoidal frame 63 is fixedly connected to the support plate 62. The trapezoidal frame 63 includes two symmetrically arranged inclined plates and a horizontal plate, wherein the horizontal plate is fixedly connected to the support plate 62, and the distance between the tops of the two inclined plates is less than the distance between the bottoms, so that the bottom of the trapezoidal frame 63 is in a state of spreading outwards. When the trapezoidal frame 63 moves downward to a certain distance, its inner wall can contact the capacitor and push the capacitor to the middle position of the trapezoidal frame 63 to achieve centering and positioning.

[0035] In order to avoid rigid contact between the trapezoidal frame 63 and the capacitor and cause damage to the capacitor, an airbag 64 is connected inside the trapezoidal frame 63. The shape of the airbag 64 is adapted to the trapezoidal frame 63, and both the inner side and the bottom of the airbag 64 extend outside the trapezoidal frame 63, so that during the downward movement of the trapezoidal frame 63, the airbag 64 will first contact the capacitor, thereby avoiding rigid contact between the trapezoidal frame 63 and the surface of the capacitor and preventing damage to the capacitor housing during the centering and positioning process.

[0036] As an implementation manner, a sliding guide rod 65 is slidably connected to the inner wall of the support plate 62. The sliding guide rod 65 can slide up and down relative to the support plate 62. The bottom end of the sliding guide rod 65 penetrates through the support plate 62 and is fixedly connected to a guide plate 66. The side of the guide plate 66 away from the support frame 4 is an inclined surface, making it triangular as a whole. By changing the transmission direction of the movement through the inclined surface, when the guide plate 66 moves downward to a certain position, its upper inclined surface will contact the end face of the capacitor without pins and push this end face towards the direction of the limiting plate 34 to achieve centering and positioning of the capacitor in the front and back directions. A flexible pad 68 is fixedly connected to the inclined surface to buffer the force received by the capacitor and avoid damage to the capacitor.

[0037] In addition, the number of the sliding guide rods 65 is at least two to improve the stability of the guide plate 66. A buffer spring 67 is sleeved outside the sliding guide rod 65, and both ends of the buffer spring 67 are connected to the support plate 62 and the guide plate 66 respectively to adapt to capacitors with different aspect ratios, so that after the guide plate 66 stops moving, the trapezoidal frame 63 can still move downward.

[0038] When the surface inkjet coding device for capacitor production of the present invention is in use, first place the capacitor to be inkjet-coded between the two positioning bars 31 of one of the limiting mechanisms 3, and then start the motor to make the conveyor belt 2 operate, so as to transport the capacitor in a specified direction. When the capacitor moves below the inkjet coding mechanism 5, the conveyor belt 2 stops operating.

[0039] Subsequently, start the electric push rod 61. The output end of the electric push rod 61 extends downward and drives the support plate 62 to move downward. The support plate 62 simultaneously drives the trapezoidal frame 63 and the guide plate 66 to move downward. During the movement, the flexible pad 68 on the inclined surface of the guide plate 66 first contacts the end face of the capacitor without pins, and pushes the capacitor in the direction of the limiting plate 34 through the inclined surface, realizing the centering limit of the capacitor between the guide plate 66 and the limiting plate 34. Subsequently, the trapezoidal frame 63 continues to move downward and compresses the buffer spring 67, so that the guide plate 66 can maintain a relatively static state. During the downward movement of the trapezoidal frame 63, the airbag 64 will first contact the capacitor and push the capacitor towards the middle position of the trapezoidal frame 63, realizing the centering positioning of the capacitor inside the trapezoidal frame 63. When both inner side walls of the airbag 64 are in close contact with the surface of the capacitor, the capacitor remains stable and the electric push rod 61 stops operating. At this time, the capacitor can be inkjet-coded through the inkjet head 53.
