DETAILED DESCRIPTION

[0040] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0041] [Example]

[0042] Combination Figure 1 and Figure 2 As shown, a circuit board wax dipping machine of this embodiment includes a frame 1, a wax dipping flow pool 2 and a circuit board pushing mechanism 5 installed on the frame 1, the wax dipping flow pool 2 is used to guide and dip the circuit board 9, and the circuit board pushing mechanism 5 is used to drive the circuit board 9 in the wax dipping flow pool 2 to move sequentially. Among them:

[0043] The wax dipping flow pool 2 has a loading end for loading the circuit board 9 and a discharging end for unloading the circuit board 9. There is a sinking track section between the loading end and the discharging end, and the sinking track section contains wax liquid. The circuit board 9 enters the wax dipping flow pool 2 from the loading end and is pushed forward driven by the circuit board pushing mechanism 5. When the circuit board 9 moves to the sinking track section, the height of the circuit board 9 decreases and contacts with the wax liquid in the sinking track section, so that the circuit board 9 is immersed in the wax liquid. It can be wax dipped as a whole or partially as needed. After the wax dipping is completed, the circuit board 9 is removed from the discharging end of the wax dipping flow pool 2 for cooling, so that the wax liquid solidifies and adheres to the circuit board 9.

[0044] The circuit board pushing mechanism 5 has a plurality of pushing components that can be controlled to move synchronously horizontally and vertically. The plurality of pushing components are arranged at intervals along the flow direction of the wax immersion flow pool 2. The reciprocating horizontal and vertical movements of the pushing components drive the circuit board 9 in the wax immersion flow pool 2 to move intermittently from the loading end to the discharging end through the sinking track section. Under the push of the circuit board pushing mechanism 5, the circuit board 9 can move forward intermittently in the wax immersion flow pool 2, and each circuit board 9 will stay longer in the wax immersion flow pool 2. The wax immersion time of the circuit board 9 is related to the length of the sinking track section of the wax immersion flow pool 2, and the length of the sinking track section can be set as needed.

[0045] By adopting the circuit board wax dipping machine, the wax dipping circulation pool 2 and the circuit board pushing mechanism 5 are cooperated to realize the circulation movement of the circuit board 9 in the wax dipping circulation pool 2, and the wax dipping treatment is realized by utilizing the sinking track section in the wax dipping circulation pool 2. The circuit board 9 is continuously and efficiently circulated and waxed, and the circuit board 9 is tilted in and out of the wax liquid, which is not easy to generate bubbles. The wax dipping is more comprehensive and stable, thereby ensuring the quality of the circuit board wax dipping.

[0046] like Figure 3 and Figure 4As shown, in the present embodiment, the wax immersion circulation pool 2 comprises a wax liquid pool 2-1 and a circulation track 2-2 passing horizontally through the wax liquid pool 2-1. The wax liquid pool 2-1 is used to store liquid wax, and the circulation track 2-2 is used to guide the circulation of the circuit board 9. The circulation track 2-2 is located in the wax liquid pool 2-1, and the track surface is lower than the upper edge of the wax liquid pool 2-1, forming the above-mentioned sunken track section, so that when the circuit board 9 flows and moves into the wax liquid pool 2-1, the height of the circuit board 9 decreases and is immersed in the wax liquid in the wax liquid pool 2-1. The structure of the wax immersion circulation pool 2 is simple and easy to process and manufacture. For further reference Figure 4 As shown, the above-mentioned circulation track 2-2 includes a limiting side plate 2-2-1 and a supporting track plate 2-2-2. The supporting track plate 2-2-2 is located on the inner side of the limiting side plate 2-2-1, and the supporting surface of the supporting track plate 2-2-2 is lower than the upper edge of the limiting side plate 2-2-1. The limiting side plate 2-2-1 and the supporting track plate 2-2-2 are relatively provided with two groups. The spacing between the two groups of limiting side plates 2-2-1 is equivalent to the width of the circuit board 9, which can limit and guide the circuit board 9; the two groups of supporting track plates 2-2-2 are respectively supported on the lower edges of both sides of the circuit board 9, so that the circuit board 9 can move along the upper track surface of the supporting track plate 2-2-2. That is, the moving trajectory of the circuit board 9 is determined by the upper track surface of the supporting track plate 2-2-2. There is a concave section 2-2-2a in the middle of the support track plate 2-2-2, and the two ends of the concave section 2-2-2a are transitioned through an inclined surface, and a stop step 2-2-2b is also provided on the transition inclined surface of the concave section 2-2-2a near the discharge end. At the feeding end, the circuit board 9 is not dipped in wax, and the friction between it and the transition inclined surface near the feeding end will not cause the circuit board 9 to move. Under the action of the circuit board pushing mechanism 5, the circuit board 9 passes through the transition inclined surface near the feeding end and enters the concave section 2-2-2a to achieve wax dipping. On the transition inclined surface near the discharge end, since the friction between the circuit board 9 and the support track plate 2-2-2 is reduced after being dipped in wax, the stop step 2-2-2b can prevent the circuit board 9 from sliding back. The limiting side plate 2-2-1 and the supporting track plate 2-2-2 are combined to form a circulation track, which has a simple structure and good circulation guiding and supporting effects on the circuit board 9. Moreover, the track path on the supporting track plate 2-2-2 is easy to process and manufacture, and the stop step 2-2-2b can prevent the circuit board 9 from sliding on the transition slope after wax dipping and causing unnecessary movement, thereby ensuring the circulation stability of the circuit board. The transition slopes at the feeding end and the unloading end allow the circuit board to be dipped into the wax liquid at an angle and moved out at an angle, which can effectively drive out bubbles and reduce dead corners for wax dipping.

[0047] catch Figure 4As shown, in this embodiment, the part of the limiting side plate 2-2-1 and the supporting track plate 2-2-2 located in the wax liquid pool 2-1 is also provided with a plurality of circulation holes 2-3, which can be round holes or strip holes, etc., so that the wax liquid inside and outside the circulation track 2-2 can circulate, and the wax liquid can be replenished from the outside of the circulation track 2-2, thereby reducing the impact on the normal wax dipping work. A heater 2-4 is also provided in the wax liquid pool 2-1 to prevent the wax liquid from solidifying.

[0048] Reference Figure 2 and Figure 5 As shown, in the present embodiment, the circuit board pushing mechanism 5 comprises a pushing fixed plate 5-1, a lifting slide plate 5-2, a lifting guide assembly 5-3, a lifting drive 5-4, a pushing drive 5-5, a pushing guide rail 5-6 and a fixed slider 5-7. The pushing fixed plate 5-1 is fixedly mounted on the frame 1. The lifting slide plate 5-2 is mounted on the pushing fixed plate 5-1 through the lifting guide assembly 5-3. The lifting guide assembly 5-3 can be a guide rail slider structure, so that the lifting slide plate 5-2 can slide up and down relative to the pushing fixed plate 5-1. The lifting drive 5-4 is fixed on the pushing fixed plate 5-1, and the driving end of the lifting drive 5-4 is connected to the lifting slide plate 5-2, and the lifting slide plate 5-2 is driven by the lifting drive 5-4 to move up and down. The push driver 5-5 is horizontally mounted on the lifting slide 5-2, the push guide rail 5-6 is horizontally slidably arranged on the lifting slide 5-2 through the fixed slider 5-7, the push assembly is mounted on the push guide rail 5-6, the driving end of the push driver 5-5 is connected to the push guide rail 5-6 or one of the push assemblies, and the push driver 5-5 drives the push guide rail 5-6 to move horizontally, thereby driving each group of push assemblies to reciprocate. The above-mentioned push assembly includes a push seat 5-8 and a push rod 5-9 installed at the lower part of the push seat 5-8, and the push seat 5-8 is fixed on the push guide rail 5-6. Two push rods 5-9 can be provided on the push seat 5-8 to ensure the balance of pushing the circuit board 9. The above-mentioned lifting driver 5-4 and the push driver 5-5 are preferably linear cylinders. The above-mentioned circuit board pushing mechanism 5 adopts the lifting and horizontal pushing actions to drive each group of push assemblies to move synchronously, the structure is simple and compact, and the pushing action of the circuit board 9 is stable and reliable.

[0049] like Figure 2 and Figure 3As shown, a circuit board wax dipping machine of this embodiment is provided with a feeding pusher 3 and a feeding stopper 4 at the feeding end of the wax dipping flow pool 2. The pushing direction of the feeding pusher 3 is consistent with the flow movement direction of the circuit board 9 in the wax dipping flow pool 2. After the circuit board 9 is placed in the feeding end of the wax dipping flow pool 2, the feeding pusher 3 pushes the circuit board 9 forward, so that the circuit board pushing mechanism 5 can push it in the next step, so as to realize the rapid feeding of the circuit board 9. The feeding stopper 4 is arranged on the side of the wax dipping flow pool 2, and the driving end of the feeding stopper 4 is provided with a limit stopper 4-1 that can be telescopically moved in the wax dipping flow pool 2. The feeding stopper 4 can prevent the feeding pusher 3 from pushing the circuit board 9 due to the inertia of the circuit board 9, thereby ensuring the accuracy of the feeding position of the circuit board 9. The above-mentioned feeding pusher 3 and feeding limiter 4 are preferably linear cylinders. When working, the feeding limiter 4 drives the limit block 4-1 to extend into the wax immersion flow pool 2, and the feeding pusher 3 pushes the circuit board 9 to move forward and is blocked and limited by the limit block 4-1. When the circuit board pushing mechanism 5 is working, the limit block 4-1 is driven to retract by the feeding limiter 4.

The arrangement seat plate 6-2 can be moved to switch the arrangement slots 6-2-1 in different positions to be connected to the discharge end of the wax immersion flow pool 2, so that the circuit boards 9 originally arranged in a row can be converted into one row, so that the circuit boards in the wax immersion flow pool 2 are temporarily stored on the arrangement seat plate 6-2. Specifically, the circuit board temporary storage mechanism 6 preferably adopts a screw nut transmission mechanism to drive the arrangement seat plate 6-2 to move, and specifically includes a motor 6-1, a transmission screw 6-3 and a transmission nut 6-4. The transmission screw 6-3 is arranged parallel to the moving direction of the arrangement seat plate 6-2. The motor 6-1 is connected to the transmission screw 6-3 by transmission. The transmission nut 6-4 is installed on the transmission screw 6-3 and is fixedly connected to the arrangement seat plate 6-2. The motor 6-1 drives the transmission screw 6-3 to rotate, and then drives the arrangement seat plate 6-2 to move, and the moving position of the arrangement seat plate 6-2 is accurately controlled. The above-mentioned circuit board temporary storage mechanism 6 can orderly arrange the circuit boards 9 after wax dipping, and can transfer the circuit boards 9 in the wax dipping flow pool to the circuit board temporary storage mechanism 6 when the equipment is shut down due to maintenance, so as to prevent the circuit boards 9 from being damaged due to long-term high-temperature wax dipping during shutdown.

The circuit board transfer mechanism 7 has a grabbing component that is controlled to transfer between the discharge end of the wax dipping flow tank 2 and the subsequent process equipment, and is used to grab and transfer the circuit board 9 on the arrangement seat plate 6-2 to the subsequent process equipment.

A clamping groove 7-8a is provided at the lower part of the clamping claw 7-8. The width of the clamping groove 7-8a is adapted to the thickness of the circuit board 9.

In addition, in order to ensure accurate positioning, a positioning pin 7-9 and an elastic pin 7-10 are also provided at the lower end of the clamping jaw driver 7-7. The position of the positioning pin 7-9 corresponds to the process hole on the circuit board 9.
