Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to an auxiliary tooling for pressing glue. Background Technology

[0002] In circuit board production, adhesive is used for dispensing. Before use, the adhesive needs to be centrifuged to remove air bubbles. After centrifugation and degassing, the gas inside the adhesive is thrown out, and the piston of the dispensing tube is pushed up by the gas. If used directly, problems such as the piston not sinking or dispensing air bubbles may occur. In particular, if the piston does not sink, the adhesive sensor of the dispensing equipment will misjudge the piston position and continue dispensing, resulting in insufficient adhesive, air bubbles, or white adhesive.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment discloses an adhesive pressing auxiliary tool, suitable for pressing a dispensing tube 10 with a piston 11. The adhesive pressing auxiliary tool includes a base 100, a bracket 200, a fixing ring assembly 300, and a crank-rocker mechanism 400. The base 100 is provided with a positioning block 110, and the positioning block 110 is provided with a positioning cavity 111. The bracket 200 is mounted on the base 100 and is located adjacent to the positioning block 110. The fixing ring assembly 300 is mounted on the bracket 200 and is located above the positioning cavity 111. The fixing ring assembly 300 is used to fix the dispensing tube 10. The crank-rocker mechanism 400 includes a guide ring 410, a pressure rod 420, a handle 430, and a connecting rod 440. The guide ring 410 is connected to the bracket 200 and is located above the fixing ring assembly 300. The pressure rod 420 is movably inserted through the guide ring 410. The handle 430 is rotatably connected to the bracket 200 at a first rotation fulcrum. Figure 2 and Figure 3 As indicated by mark A, handle 430 and connecting rod 440 are rotatably connected to the second rotation fulcrum, as shown below. Figure 2 and Figure 3 As indicated by mark B, connecting rod 440 and pressure rod 420 are rotatably connected at the third rotation fulcrum, as shown below. Figure 2 and Figure 3 As shown in the middle marked C, please refer to... Figure 3 The pressure rod 420 can abut against the piston 11 of the dispensing tube 10, and the first rotation fulcrum, the second rotation fulcrum, and the third rotation fulcrum are located on the same longitudinal straight line.

[0032] In use, the dispensing tube 10 is placed on the positioning block 110 of the base 100. The positioning block 110 of the base 100 can position the dispensing tube 10 and, together with the fixing ring assembly 300, fix the dispensing tube 10 so that the dispensing tube 10 is placed vertically. Figure 1 and Figure 2 As shown, in the initial state, the pressure rod 420 and the dispensing tube 10 are not in contact; the user can rotate the handle 430 of the crank-rocker mechanism 400, which will drive the pressure rod 420 downward through the connecting rod 440, so that the pressure rod 420 of the crank-rocker mechanism 400 can abut against the piston 11 of the dispensing tube 10, as shown. Figure 3As shown, in the contact state, the guide ring 410 guides and limits the pressure rod 420. Since the first rotation fulcrum, the second rotation fulcrum, and the third rotation fulcrum are located on the same longitudinal line, the handle 430, the connecting rod 440, and the pressure rod 420 are in a locked state. The pressure rod 420 can apply continuous pressure to the piston 11 of the dispensing tube 10, keeping the dispensing tube 10 in a high-pressure state, squeezing out air bubbles in the dispensing tube 10, preventing the piston 11 from sinking, and improving the dispensing quality.

[0033] Please refer to Figure 2 and Figure 3 The positioning cavity 111 is provided with a contoured surface 112 adapted to the bottom of the dispensing tube 10, and a positioning hole 113 adapted to the protrusion at the bottom end of the dispensing tube 10 is provided in the middle of the contoured surface 112. The square surface can guide the placement of the dispensing tube 10, so that the dispensing tube 10 can be easily placed in the positioning cavity 111. The positioning hole 113 cooperates with the protrusion at the bottom end of the dispensing tube 10 for precise positioning, and the movement gap between the positioning hole 113 and the protrusion at the bottom end of the dispensing tube 10 is small, which can play a certain role in fixing the dispensing tube 10. In some application examples, the contoured surface 112 is provided with an anti-slip layer. The protective layer can increase the friction between the contoured surface 112 and the dispensing tube 10, making the placement of the dispensing tube 10 more stable.

[0034] In some application examples, there are multiple fixing ring assemblies 300, which are spaced apart in the longitudinal direction. For example, please refer to... Figure 1 There are two fixing ring assemblies 300, arranged vertically, to fix the dispensing tube 10 at different heights. In some application examples, the fixing ring assembly 300 includes a ring seat 310 and a retaining ring 320. The ring seat 310 is mounted on the bracket 200 and connected to the retaining ring 320. The retaining ring 320 forms an adjustable fixing area through which the dispensing tube 10 passes. For example, the ring seat 310 is fitted onto the bracket 200, and the retaining ring 320 can be a ring-shaped structure formed by a flexible metal strip. The tightness of the retaining ring 320 can be adjusted to regulate the size of the fixing area, thus accommodating dispensing tubes 10 of different sizes. Alternatively, the retaining ring 320 can be a clamp structure used to adjust the size of the fixing area.

[0035] In some application examples, please refer to [link / reference]. Figure 1A knob fastener 330 is provided on the ring seat 310. The knob fastener 330 passes through the ring seat 310 and is threadedly connected to the ring seat 310, and the end of the knob fastener 330 abuts against the bracket 200. The knob fastener 330 can fix the ring seat 310 to the bracket 200 by abutting against the bracket 200. Loosening the knob fastener 330 can allow the ring seat 310 to move relative to the bracket 200, thereby adjusting the relative position of the ring seat 310 on the bracket 200, and thus accommodating dispensing tubes 10 of different heights.

[0036] In some application examples, please refer to Figure 1 and Figure 2 The end of the pressure rod 420 is provided with a piston head 421. The piston head 421 has a larger contact area, which can apply the same pressure to all positions of the piston 11 of the dispensing tube 10, ensuring that the piston 11 is subjected to uniform force. In some application examples, the piston head 421 is a soft head, which can buffer between the pressure rod 420 and the piston 11, avoiding damage to the piston 11 due to contact between the pressure rod 420 and the piston 11.

[0037] Please refer to Figure 2 and Figure 3 The bracket 200 is also equipped with a fixed back plate 210, which has a first connecting arm 220 and a second connecting arm 230. The first connecting arm 220 is connected to the fixed ring, and the second connecting arm 230 is rotatably connected to the handle 430 at the first rotation fulcrum. By setting the first connecting arm 220 and the second connecting arm 230 on the fixed back plate 210, the structures of the guide ring 410 and the handle 430 can be integrated into the same mechanism, so that the dimensions and spacing between the handle 430, the connecting rod 440 and the guide ring 410 meet the expected design. That is, when the first rotation fulcrum, the second rotation fulcrum and the third rotation fulcrum are located on the same longitudinal line, the pressure rod 420 enters the locked state, thereby continuously applying pressure to the piston 11. In addition, the fixed back plate 210 can also move as a whole with the first connecting arm 220 and the second connecting arm 230. For example, the fixed back plate 210 is also provided with a position adjustment knob 240, which is suitable for adjusting the installation position of the fixed back plate 210 on the bracket 200. In this way, the pressure of the pressure rod 420 on the piston 11 can be adjusted and the dispensing tube 10 of different heights can be accommodated.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
