Description

Technical Field

[0001] This utility model relates to the technical field of chip resistor production and processing, specifically a drying device for chip resistor production. Background Technology

[0002] In the production of surface mount resistors, the main function of the drying device is to remove moisture and other residual substances left over from the manufacturing process, so that the surface mount resistors are less likely to develop bubbles, cracks or short circuits in subsequent processing, thereby improving the processing quality of surface mount resistors.

[0035] Please see Figure 1-4 As shown, this utility model provides a technical solution for a drying device used in the production of surface mount resistors:

[0036] A drying device for producing surface mount resistors includes a frame 1, on which a drying chamber 11, a support plate 2, a transmission mechanism 4, and a drive motor 12 are mounted. The drying chamber 11 is located on one side of the frame 1 and is fixedly connected to the frame 1. The horizontally arranged support plate 2 is located on one side of the drying chamber 11 and is slidably connected to the top of the frame 1 along the length direction of the frame 1. The support plate 2 has a plurality of ventilation holes 21 in the vertical direction, which are evenly distributed along the length direction of the support plate 2. Surface mount resistors are placed on the support plate 2.

[0037] Support frame 22 and limiting member 3 are installed on support plate 2. There are two support frames 22, which are located on both sides of support plate 2. Each support frame 22 is L-shaped and its bottom is fixedly connected to the top of support plate 2. There are two limiting members 3, which correspond one-to-one with the two support frames 22. Each limiting member 3 includes a limiting block 31, a limiting rod 32 and a spring 33. The horizontally arranged limiting block 31 is located at the top of the chip resistor and its bottom is used to abut against the top of the chip resistor for limiting. One end of the vertically arranged limiting rod 32 is fixedly connected to the top of the limiting block 31 and its other end passes through the support frame 22 and is slidably connected to the top of the support frame 22. The vertically arranged spring 33 is sleeved on the limiting rod 32 and its bottom is fixedly connected to the top of the limiting block 31. The top of the spring 33 is fixedly connected to the bottom wall of support frame 22.

[0038] The transmission mechanism 4 includes a rotating shaft 41, a transmission shaft 42, and a transmission component, the transmission component including a transmission block 43. The drive motor 12 is located on the side of the support plate 2 away from the drying chamber 11, and the bottom of the drive motor 12 is fixedly connected to the top of the frame 1. The output shaft of the drive motor 12 is coaxially fixedly connected to the rotating shaft 41. The axial direction of the horizontally arranged rotating shaft 41 is consistent with the length direction of the frame 1. A rotating groove 51 is coaxially formed at the end of the rotating shaft 41 away from the drive motor 12. The rotating groove 51 is horizontally arranged. One end of the horizontally arranged transmission shaft 42 extends into the rotating groove 51 and is slidably connected to the side wall of the transmission groove 52. The other end of the transmission shaft 42 is fixedly connected to the side of the support portion away from the drying chamber 11. A transmission groove 52 is provided on the outer peripheral wall of the transmission 2. The length direction of the transmission groove 52 is consistent with the axial direction of the transmission shaft 42. A horizontally arranged transmission block 43 is located in the rotating groove 51. One side of the transmission block 43 is fixedly connected to the side wall of the rotating groove 51, and the other side of the transmission block 43 extends into the transmission groove 52 and is slidably connected to the side wall of the transmission groove 52. A ball bearing 53 is installed on the transmission block 43. One side of the ball bearing 53 is rotatably connected to the side wall of the transmission block 43, and the other side of the ball bearing 53 is used to contact the side wall of the transmission groove 52 on the transmission shaft 42, thereby reducing wear and extending the service life of the transmission block 43.

[0039] Using the elastic potential energy of spring 33, the limiting rod 32 drives the limiting block 31 to rise and fall vertically until the bottom of the limiting block 31 contacts the top of the chip resistor, thereby limiting the chip resistor and improving its stability. The operator starts the drive motor 12, and the output shaft of the drive motor 12 rotates, causing the rotating shaft 41 to rotate synchronously. Through the transmission block 43 and the transmission groove 52, the transmission shaft 42 rotates with the rotating shaft 41, thereby driving the support plate 2 and the chip resistor to rotate synchronously. The chip resistor rotates inside the drying oven 11, ensuring uniform heating and improving the processing quality of the chip resistor.

[0040] A drive component 7 and a drive plate 6 are mounted on the drive shaft 42. There are two drive components 7, located on opposite sides of the rotating shaft 41. Each drive mechanism includes a drive cylinder 71 and a drive rod 72. The start cylinder is located on the frame 1 and on one side of the drive motor 12. The cylinder body of the drive cylinder 71 is fixedly connected to the top of the frame 1, and the piston rod of the drive cylinder 71 is coaxially fixedly connected to the drive rod 72. The horizontally positioned end of the drive rod 72 away from the drive cylinder 71 is fixedly connected to the side wall of the drive plate 6. The vertically positioned drive plate 6 is sleeved on the drive shaft 42 and is rotatably connected to the drive shaft 42 via a bearing 61.

[0041] The operator starts the drive cylinder 71. The piston rod of the drive cylinder 71 extends and retracts, causing the drive rod 72 to move synchronously, which in turn causes the drive plate 6 to move synchronously. The drive plate 6 moves along the length of the frame 1, causing the transmission shaft 42 to move synchronously, thereby causing the support plate 2 and the chip resistor to move synchronously at one end. This makes it convenient for the operator to transfer the support plate 2. After the chip resistor is dried in the drying oven 11, it is convenient for the operator to detach the support plate 2 and the chip resistor from the drying oven 11.

[0042] The working principle of this utility model is as follows:

[0043] In this embodiment, a drying device for producing surface mount resistors is used when the operator starts the drive cylinder 71. The piston rod of the drive cylinder 71 extends and retracts, causing the drive rod 72 to move synchronously. This, in turn, causes the drive plate 6, the transmission shaft 42, and the support plate 2 to move in a direction close to the drying chamber 11 until the support plate 2 and the surface mount resistors are transferred into the drying chamber 11, thereby drying the surface mount resistors.

[0044] The operator then restarts the drive motor 12. The output shaft of the drive motor 12 rotates, causing the rotating shaft 41 to rotate synchronously. Through the transmission block 43 and the transmission groove 52, the transmission shaft 42 rotates along with the rotating shaft 41, thereby causing the surface mount resistors on the support plate 2 to rotate synchronously. Through the elastic potential energy of the spring 33, the surface mount resistors are less likely to detach from the support plate 2, improving their stability. Simultaneously, the surface mount resistors rotate within the drying chamber 11, ensuring uniform heating and preventing uneven heating from affecting the processing quality of the surface mount resistors, thus improving their overall quality.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
