Description

Technical Field

[0001] This utility model relates to the field of electric heating equipment manufacturing, and in particular to a surface adhesive dispensing device for the production of PTC ceramic heaters. Background Technology

[0002] Ceramic heating elements are electric heaters that use ceramic elements to achieve heating. They are widely used in many fields. During the production process, adhesive needs to be printed on the surface of the ceramic heating element to firmly fix the ceramic element inside the metal tube, thereby preventing it from loosening or falling off due to vibration or temperature changes during operation.

[0003] The printing of adhesive is a crucial step in the production process, and its quality directly affects the overall performance and lifespan of the heater. Currently, manual screen printing tables, as a traditional printing process, require manual operation to print adhesive onto ceramic heating elements. During operation, the operator needs to repeatedly use a squeegee to print adhesive back and forth on the surface of the ceramic heating element, precisely controlling the force and angle of the squeegee. These operations all rely on manual labor, and prolonged manual operation may lead to muscle fatigue and soreness in the arms and wrists, thus affecting printing efficiency. Utility Model Content

[0004] In order to overcome the cumbersome dispensing operation of the existing technology, the technical problem of this utility model is to provide a surface dispensing device for the production of PTC ceramic heaters that is easy to operate.

[0005] The technical implementation scheme of this utility model is as follows: a surface glue dispensing device for the production of PTC ceramic heaters, including a printing table, a glue dispensing table rotatably connected to the printing table, a support frame fixedly connected to the glue dispensing table, a pressure plate provided on the glue dispensing table, sliding blocks symmetrically provided on the pressure plate, and the pressure plate and the sliding blocks fixedly connected, the sliding blocks sliding on the support frame, an operating lever rotatably connected to the pressure plate, the operating lever being used to drive the pressure plate to press down glue, a mounting base fixedly connected to the rear side of the glue dispensing table, a connecting plate rotatably connected to the mounting base, and the top of the connecting plate rotatably connected to the operating lever.

[0006] Furthermore, it also includes a fixed shell, which is fixedly connected to the front side of the printing table. A buckle is rotatably connected to the fixed shell. The buckle is used to fix and keep the dispensing table in a horizontal and positive position to ensure the stability of the dispensing process. A spring is provided between the fixed shell and the buckle. One end of the spring is fixedly connected to the fixed shell, and the other end of the spring is fixedly connected to the buckle. The spring is used to reset the buckle.

[0007] Furthermore, it also includes an anti-slip pad, with the bottom of the printing table fixedly connected to an anti-slip pad for increasing friction.

[0008] Furthermore, it also includes a storage box, which is fixedly connected to the right side of the printing table for placing items.

[0009] Furthermore, it also includes an anti-slip sleeve, with the front end of the control lever fixedly connected to an anti-slip sleeve to prevent accidental slippage.

[0010] Furthermore, it also includes lighting lamps, with symmetrical lighting lamps for providing light on the support frame, and the support frame is fixedly connected to the lighting lamps.

[0011] The present invention has the following advantages: 1. By lifting the control lever, it will drive the pressure plate and the sliding block to slide on the support frame. At the same time, the rear end of the control lever will drive the connecting plate to rotate on the mounting base. Then, the control lever is pressed down. The process is reversed. The pressure plate will squeeze the glue, thereby evenly squeezing the glue onto the surface of the ceramic heating element, so as to facilitate the operation of the operator.

[0012] 2. By pressing down on the dispensing table, the latch compresses the spring, and the dispensing table contacts the latch. The spring then relaxes and resets the latch, thus securing the dispensing table firmly to the printing table and preventing accidental slippage during operation, allowing it to automatically reset.

[0013] 3. The lighting provides sufficient light, effectively preventing operational errors caused by dim lighting and improving the accuracy and safety of the operation. Attached Figure Description

[0018] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0019] Example: A surface adhesive dispensing device for the production of PTC ceramic heaters, such as... Figure 1-3 As shown, the assembly includes a printing table 1, a dispensing table 2, a support frame 3, a pressure plate 4, sliding blocks 5, a control lever 6, a mounting base 7, and a connecting plate 8. The dispensing table 2 is rotatably connected to the printing table 1, and the support frame 3 is fixedly connected to the dispensing table 2. The pressure plate 4 is mounted on the dispensing table 2, and the sliding blocks 5 are symmetrically arranged on the pressure plate 4. The pressure plate 4 and the sliding blocks 5 are fixedly connected. The sliding blocks 5 slide on the support frame 3, and the control lever 6 is rotatably connected to the pressure plate 4. The control lever 6 is used to drive the pressure plate 4 to press down the glue. The mounting base 7 is fixedly connected to the rear side of the glue dispensing table 2. The connecting plate 8 is rotatably connected to the mounting base 7. The top of the connecting plate 8 is rotatably connected to the end of the control lever 6. The control lever 6 also includes a storage box 13. The right side of the printing table 1 is fixedly connected to the storage box 13 for placing items. The control lever 6 also includes an anti-slip sleeve 14. The front end of the control lever 6 is fixedly connected to the anti-slip sleeve 14 to prevent accidental slippage.

[0020] like Figure 1 and Figure 3 As shown, it also includes a fixed shell 9, a buckle 10, and a spring 11. The fixed shell 9 is fixedly connected to the front side of the printing table 1, and the buckle 10 is rotatably connected to the fixed shell 9. The buckle 10 is used to fix and keep the glue dispensing table 2 in a horizontal and positive position to ensure the stability of the glue dispensing process. The spring 11 is provided between the fixed shell 9 and the buckle 10. One end of the spring 11 is fixedly connected to the fixed shell 9, and the other end of the spring 11 is fixedly connected to the buckle 10. The spring 11 is used to reset the buckle 10.

[0021] When using a manual screen printing table to print ceramic heating elements, the operator first prepares the printing adhesive material, lifts the control lever 6, and the control lever 6 rotates on the pressure plate 4, causing the pressure plate 4 to move upward. Since the pressure plate 4 is fixedly connected to the sliding block 5, the upward movement of the pressure plate 4 causes the sliding block 5 to slide upward on the support frame 3. At the same time, the rear end of the control lever 6 causes the connecting plate 8 to rotate on the mounting base 7. The operator then evenly pours the adhesive onto the dispensing table 2, completing the process. Then, the glue container is placed inside the storage box 13, which facilitates the operator in placing items, improving work efficiency and ease of use. When the control lever 6 is lowered, the process is reversed. The control lever 6 will drive the pressure plate 4 and the sliding block 5 to move downward on the support frame 3. Subsequently, the operator rotates the buckle 10 outward on the fixed shell 9, compressing the spring 11. The glue dispensing platform 2 rotates open on the printing table 1, disengaging from the buckle 10. After the spring 11 extends, the buckle... The latch 10 rotates and resets on the fixed housing 9. The operator places the ceramic heating element to be printed onto the printing table 1 and manually presses down the glue dispensing platform 2. The glue dispensing platform 2 will squeeze the latch 10, and the spring 11 will reset the latch 10. The glue dispensing platform 2 will then contact the latch 10, securing it firmly to the printing table 1 and preventing accidental slippage during operation. The operator then lifts and presses down the control lever 6 again, and the pressure plate 4 will squeeze glue through the glue dispensing platform 2 to print onto the ceramic heating element. The adhesive is evenly squeezed and printed onto the surface of the ceramic heating element, making it easy for operators to use. The anti-slip sleeve 14 on the control lever 6 prevents the operator from accidentally slipping during use, thereby improving the ease of operation. When the other side of the ceramic heating element needs to be printed, the buckle 10 is rotated again, the glue dispensing platform 2 rotates, the operator rotates and flips the ceramic heating element and places it on the printing platform 1, then presses down the glue dispensing platform 2 and operates the control lever 6. By doing so, the printing on the surface of the ceramic heating element can be completed.

[0022] like Figure 1 As shown, it also includes an anti-slip pad 12, which is fixedly connected to the bottom of the printing table 1 to increase friction.

[0023] The anti-slip pad 12 increases the friction between the bottom of the printing table 1 and the platform surface, thereby improving the stability during operation and preventing slippage.

[0024] like Figure 1 As shown, it also includes a lighting lamp 15. The lighting lamp 15 is symmetrically provided on the support frame 3 for providing light, and the support frame 3 is fixedly connected to the lighting lamp 15.

[0025] The lighting lamp 15 provides sufficient light, thereby effectively preventing operational errors caused by dim lighting and improving the accuracy and safety of the operation.
