Description

Technical Field

[0001] This utility model belongs to the field of screen printing, specifically relating to a cooling device for screen printing of ceramic resistor elements. Background Technology

[0002] After the ceramic resistor element is screen printed and dried, it needs to be cooled before the next processing step. The common cooling method is to send the dried ceramic resistor element into a linearly extending cooling channel, so that the dried ceramic resistor element moves in a straight line along the cooling channel and is cooled down by the cooling channel. However, to ensure the cooling effect, this cooling method requires that the cooling channel has a sufficient length, which results in the cooling channel occupying a large space.

[0021] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0022] See Figures 1-10 The cooling device for screen printing of ceramic resistor elements of this utility model includes a frame 1, multiple cooling modules mounted on the frame 1, and a material conveying module 2 for conveying a material box 14 containing ceramic resistor elements to one of the cooling modules. The multiple cooling modules are arranged in parallel. A transfer module 6 is provided between adjacent cooling modules to transfer the material box 14, which has completed preliminary cooling in the previous cooling module, to the next cooling module for further cooling. Each cooling module includes a support 7 and a vertical circulation drive mechanism 11 mounted on the support 7 for driving the vertical movement of the material box 14. The movement directions of the material box 14 in the two adjacent vertical circulation drive mechanisms 11 are opposite. The positions of the two adjacent transfer modules 6 are also opposite.

[0023] In this embodiment, there are two sets of cooling modules, namely a first cooling module 3 and a second cooling module 4. The material conveying module 2 is located below the first cooling module 3 and is used to convey the material box 14 to the first cooling module 3. After the material box 14 is initially cooled by the first cooling module 3, it is transferred to the second cooling module 4 by the transfer module 6. After the material box 14 is cooled again by the second cooling module 4, the downstream conveyor line 5 conveys the cooled material box 14 in the second cooling module 4 to the downstream processing station. The transfer module 6 is located above the first cooling module 3 and the second cooling module 4.

[0024] See Figures 1-10 The vertical circulation drive mechanism 11 consists of two sets, arranged side by side, with the space between them forming a vertical conveying channel for conveying the material box 14. Each set of vertical circulation drive mechanism 11 includes a chain 113, a support plate 111 mounted on the chain 113, and a vertical drive mechanism for driving the chain 113 to circulate vertically. The support plates 111 are arranged in multiple sets, equidistantly along the circumferential direction of the chain 113. The support plates 111 on the chain 113 in the two sets of vertical circulation drive mechanisms 11 correspond one-to-one, thus forming a conveying trough for conveying the material box 14. The material box 14 is located within the conveying trough.

[0025] In this embodiment, the vertical drive mechanism is located below the support 7 and includes a drive sprocket 118, a driven sprocket, and a power drive mechanism for driving the drive sprocket 118 to rotate. The drive sprocket 118 is located below the support 7 and is rotatably connected to the support 7 via a first rotating shaft 115. The driven sprocket is located above the support 7 and is rotatably connected to the support 7 via a second rotating shaft. The chain 113 is wrapped around the drive sprocket 118 and the driven sprocket. The power drive mechanism includes a drive motor 114 and a reducer 116. The drive motor 114 is mounted on the support 7, and the main shaft of the drive motor 114 is connected to the input shaft of the reducer 116. The output shafts on both sides of the reducer 116 are respectively connected to the first rotating shaft 115 of the two sets of vertical circulating drive mechanisms 11 via a bevel gear transmission mechanism 117.

[0026] The drive motor 114 drives the reducer 116 to work, thereby driving the first shaft 115 in the two sets of vertical circulation drive mechanisms 11 to rotate, thereby driving the drive sprocket 118 and the driven sprocket to rotate, and in turn driving the chains 113 in the two sets of vertical circulation drive mechanisms 11 to move synchronously. In this way, the pallets 111 set on the two sets of chains 113 also move synchronously, thereby driving the material box 14 on the pallet 111 to move up or down.

[0027] See Figures 1-10 In the two sets of vertical circulating drive mechanisms 11, the chain 113 on the side closest to the vertical conveying channel is the first chain section, and the other side is the second chain section. The bracket 7 has a vertically extending guide post 113 at a position corresponding to the first chain section. The guide post 113 has a vertically extending guide portion. The back side of the first chain section has a guide groove that mates with the guide portion. By setting the guide post 113, the first chain section of the chain 113 can be supported and guided, thereby preventing the chain 113 from swaying left and right during vertical movement, and thus enabling the material box 14 to rise and fall smoothly.

[0028] See Figures 1-10A guide assembly 10 is provided on the upper or lower side of the vertical conveying channel. There are two sets of guide assemblies 10, which are arranged on the left and right sides of the vertical conveying channel. Each set of guide assemblies 10 includes two guide plates arranged on the front and rear sides of the vertical conveying channel. The guide plates are composed of arc-shaped plates and straight plates. One end of the straight plate is connected to the bracket 7, and the other end is connected to the arc-shaped plate. The four arc-shaped plates form a guide opening. The opening of the guide opening faces the opposite direction to the conveying direction of the vertical conveying channel. The guide opening formed by the four arc-shaped plates can guide the vertically moving material box 14 to smoothly enter the guide space formed by the four straight plates. The four straight plates can limit the front and rear directions of the left and right sides of the material box 14, thereby correcting the position of the material box 14 in the conveying groove. This allows the material box 14 in the conveying groove to be smoothly transferred by the transfer module 6 to another cooling module, or smoothly conveyed by the downstream conveying line 5 to the downstream processing station.

[0029] See Figures 1-10 The transfer module 6 includes a guide rail 604 disposed between the brackets 7 of the first cooling module 3 and the second cooling module 4, and a material box pushing mechanism for pushing the material box 14 in the conveying groove of the first cooling module 3 onto the guide rail 604 and pushing the material box 14 along the extension direction of the guide rail 604 into the conveying groove of the second cooling module 4. The material box pushing mechanism includes a support frame disposed between the brackets 7 of the two cooling modules, a push plate 603 disposed on the support frame, and a material box pushing mechanism for driving the push plate 603 to move. In this embodiment, the material box pushing mechanism adopts a driving method combining a motor 601 and a lead screw transmission mechanism 602.

[0030] Furthermore, the guide rail 604 is also provided with an outwardly inclined guide opening near the first cooling module 3 to guide both ends of the material box 14 smoothly into the guide rail 604; the bracket 7 of the second cooling module 4 is provided with two sets of baffles 12 and a detector 13 between the two sets of baffles 12 at the corresponding positions of the transfer module 6. The two sets of baffles 12 are used to limit the transfer stroke of the transfer module 6. During the process of the material box 14 being transferred to the conveying groove in the second cooling module 4 corresponding to the transfer channel of the transfer module 6, when the baffle 12 contacts the material box 14, it proves that the material box 14 has been transferred to the conveying groove of the second cooling module 4, and the detector 13 detects the material box 14; at this time, the two sets of vertical circulation drive mechanisms 11 in the second cooling module 4 move synchronously, driving the material box 14 to move downward a certain distance, so that another empty conveying groove reaches the position corresponding to the transfer channel of the transfer module 6, to receive the next material box 14 transferred by the transfer module 6.

[0031] See Figures 1-10 The support 7 is a gantry structure. Two sets of fans 9 are provided on both sides of the support 7. Each set of fans 9 consists of multiple fans, which are arranged vertically at equal intervals. The fans 9 are used to cool down the material box 14 conveyed in the vertical conveying channel between the two sets of vertical circulation drive motors. In addition, an air outlet is also provided on the top of the support 7.

[0032] In this embodiment, the guide components 10 in the first cooling module 3 and the second cooling module 4 are arranged in opposite directions; at the same time, the cooling device for screen printing process of ceramic resistor elements of this utility model is also provided with multiple sets of sensors for detecting the position of the material box 14.

[0033] See Figures 1-10 The working principle of the cooling device for screen printing process of ceramic resistor elements of this utility model is as follows:

[0034] The material conveying module 2 conveys the material box 14 to the lower part of the first cooling module 3. Then, the two sets of vertical circulation drive mechanisms 11 in the first cooling module 3 drive the material box 14 upwards a certain distance, so that the next empty conveying slot reaches the position corresponding to the material conveying module 2, and the above steps are repeated. As the two sets of vertical circulation drive mechanisms 11 drive the material box 14 upwards, the fan 9 on the bracket 7 in the first cooling module 3 works to cool the material box 14 and the ceramic resistance element inside. When the material box 14 reaches the upper part of the first cooling module 3... When the material box 14 is located at the position corresponding to the transfer module 6, the transfer module 6 transfers the material box 14 to the conveying groove above the second cooling module 4 corresponding to the transfer module 6. The two sets of vertical circulation drive mechanisms 11 in the second cooling module 4 drive the material box 14 to move downward. Similarly, the fan 9 on the bracket 7 of the second cooling module 4 works to cool the material box 14 and the ceramic resistance element inside it again. When the material box 14 reaches the position corresponding to the downstream conveyor line 5, the downstream conveyor line 5 drives the material box 14 to the downstream processing station.

[0035] The above are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above content. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
