Description

Technical Field

[0001] This utility model belongs to the field of columnar thick film resistor processing technology, specifically relating to columnar thick film resistor transfer box. Background Technology

[0002] Screen printing is a relatively mature printing process. In the screen printing process, the two ends of the columnar insulating substrate are first placed on the positioning seat while the middle is suspended. The screen is lowered by the lifting module to contact the columnar insulating substrate. The cylinder drives the squeegee to contact the screen. Then the screen is moved laterally by the transverse module while the squeegee remains stationary. The insulating substrate is rolled by the screen, thereby screen printing the resistive paste on the circumferential surface of the substrate.

[0003] After printing, the material needs to be transferred to the appropriate equipment for drying, so that the resistive paste solidifies on the insulating substrate to form a columnar thick film resistor. However, pre-drying cannot be carried out during the transfer process, and the time between screen printing and drying in the box cannot be fully utilized. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a columnar thick film resistor transfer box that can be pre-dried during the transfer process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a columnar thick film resistor transfer box, including a pre-drying box and a placement rack. The placement rack is placed inside the pre-drying box. Multiple pre-drying fans are arranged below the placement rack inside the pre-drying box. The air outlet direction of the multiple pre-drying fans is arranged facing upwards towards the placement rack. An opening for the placement rack to exit is provided on one side of the pre-drying box. An opening and closing door is rotatably connected to the opening.

[0006] Two support columns are installed on the bottom of the opening and closing door facing the inside of the pre-drying box. The support columns are located below the placement rack, and the bottom of the pre-drying box is provided with a receiving groove to accommodate the support columns.

[0007] One end of the support column is rotatably mounted with a roller.

[0008] The pre-drying box has a first handle installed on the side symmetrical to the opening, and the opening and closing door has a gripping part installed on it.

[0009] The gripping part includes a fixed ring, a connecting rod, and a second handle. The connecting rod is provided with a sliding post that cooperates with the fixed ring. The second handle is rotatably connected to the sliding post. Insert posts are installed at both ends of the connecting rod. Insert holes that cooperate with the insert posts are provided on the pre-drying box.

[0010] The placement rack is equipped with multiple semi-circular limiting frames.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this utility model, a columnar thick-film resistor transfer box is used. During transfer, the placement rack is first placed in the pre-drying box, and multiple pre-drying fans inside the pre-drying box are started. The columnar thick-film resistor to be transferred is placed on the placement rack, and the columnar thick-film resistor on the placement rack is pre-dried by the air blown out by the multiple pre-drying fans, thus achieving pre-drying during the transfer process.

[0019] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0020] like Figures 1-5As shown, this embodiment provides a transfer box for columnar thick-film resistors, including a pre-drying box 1 and a placement rack 2. The placement rack 2 is placed inside the pre-drying box 1. Multiple pre-drying fans 3 are located below the placement rack 2 inside the pre-drying box 1, with the air outlet direction of the fans 3 facing upwards towards the placement rack 2. One side of the pre-drying box 1 has an opening for the placement rack 2 to retract. An opening door 4 is rotatably connected to the opening. Rotating shafts are symmetrically located on both sides of the opening door 4, and the opening has rotating grooves that cooperate with the rotating shafts. During transfer, the placement rack 2 is first placed in the pre-drying box 1. The multiple pre-drying fans 3 inside the pre-drying box 1 are then activated, and the columnar thick-film resistors to be transferred are placed on the placement rack 2. The air blown by the multiple pre-drying fans 3 pre-dries the columnar thick-film resistors on the placement rack 2, achieving pre-drying during the transfer process. The opening door 4 facilitates opening the pre-drying box 1 to remove the placement rack 2, which is then directly placed on the conveyor belt of the subsequent process for drying.

[0021] Furthermore, two support columns 5 are installed on the bottom side of the opening and closing door 4 facing the pre-drying box 1. The support columns 5 are located below the placement rack 2, and the bottom of the pre-drying box 1 is provided with a receiving groove 6 to accommodate the support columns 5. Specifically, a roller 7 is rotatably installed at one end of the support column 5. When the opening and closing door 4 is opened, its support column 5 swings upward with the opening and closing door 4, thereby supporting the bottom of the placement rack 2, so that the bottom of the placement rack 2 is higher than the pre-drying fan 3. Then, the placement rack 2 on this side is grasped and pressed down, so that the placement rack 2 uses the roller 7 as a fulcrum to tilt the other side away from the pre-drying fan 3, while dragging the placement rack 2 outward. Thus, the other side of the placement rack 2 tilts up and is higher than the pre-drying fan 3, preventing the placement rack 2 from affecting the pre-drying fan 3 when it is pulled out. In addition, with the rolling of the roller 7, the placement rack 2 is pulled out more smoothly.

[0022] Furthermore, the pre-drying box 1 has a first handle 8 installed on the symmetrical side to the opening, and a holding part 9 installed on the opening and closing door 4. Specifically, the holding part 9 includes a fixing ring 10, a connecting rod 11, and a second handle 12. The connecting rod 11 has a sliding post that cooperates with the fixing ring 10. The second handle 12 is rotatably connected to the sliding post. Insert pins 13 are installed at both ends of the connecting rod 11, and the pre-drying box 1 has insertion holes 14 that cooperate with the insertion pins 13. During handling, the first handle 8 and the second handle 12 are held respectively, and then the box is lifted. That is, the second handle 12 will pull the sliding post, causing the connecting rod 11 to rise, so that the insertion pins 13 are placed in the insertion holes 14 from bottom to top, preventing the opening and closing door 4 from opening during handling. At this time, the first handle 8 and the second handle 12 are on the same horizontal plane.

[0023] Furthermore, the placement rack 2 is provided with multiple semi-circular limiting frames 15. The semi-circular limiting frames 15 limit the columnar thick film resistor to prevent it from rolling during transportation.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
