This utility model provides an integrated machine for coating and pressing sealant onto a protective shell, comprising: a coating assembly, which includes a movable base for moving a coating cylinder, a fixed sleeve fixed to the outside of the coating cylinder, a fixed block installed above the coating cylinder, a push rod installed inside the fixed block, the push rod extending into the coating cylinder below, and the push rod connected to a sliding base above. Compared with the prior art, this utility model has the following advantages: by setting the coating assembly, the coating assembly moves from right to left along the lower part of the support, and the push rod drives the push plate to move downward inside the coating cylinder, applying sealant to the seam of the protective shell. Several sets of ball bearings are embedded in the lower surface of the slider, and the left side of the lead screw is installed inside the bearing. Therefore, the friction can be significantly reduced when the coating assembly moves, thereby effectively weakening the vibration generated during the movement and preventing breakpoints or misalignment of the sealant seam during the coating process.

Description

Technical Field

[0001] This utility model belongs to the technical field of switching power supply equipment, and specifically relates to an integrated machine for coating and pressing protective shell sealant. Background Technology

[0002] The integrated sealant coating and pressing machine for protective housings is an automated device specifically designed for the production of switching power supplies. Its core function is to achieve efficient sealing of the housing by integrating the coating and pressing processes. The equipment first uses a precision motion system to drive a coating valve (screw valve or jet valve) to precisely apply sealant (such as silicone or polyurethane) along a preset path into the sealing groove of the power supply housing. Then, the pressing mechanism tightly adheres the housing cover to the base, forcing the sealant to fully fill the gaps and cure. However, existing equipment still has drawbacks. For example, during the coating process, complex transmission between machines can cause mechanical vibration, which may lead to slight deviation of the glue gun, resulting in glue seam breaks or misalignment. This can lead to a decrease in the quality of the protective housing coating and reduced sealing performance. Actual measurements show that the risk of seal failure exceeds 3‰ in humid and hot environments. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective shell sealant coating and pressing integrated machine to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a protective shell sealant coating and pressing integrated machine, comprising: a coating assembly, the coating assembly including a movable base for driving the coating cylinder to move, a fixed sleeve fixed to the outside of the coating cylinder, and a fixed block installed above the coating cylinder;

[0005] A push rod is installed inside the fixed block. The push rod extends into the glue-applying cylinder below and is connected to a sliding base above. A slider is provided above the sliding base. The slider is slidably installed in a groove opened on the lower surface of the bracket. Several sets of balls are embedded in the front and rear positions of the lower surface of the slider.

[0006] In a preferred embodiment, the bracket is positioned above the adhesive application assembly. The bracket has a U-shaped structure, and the top of the bracket is a sloping structure with a gradually increasing gradient from left to right. A base plate is provided below the bracket, and the base plate is installed inside the main body of the device.

[0007] The device body has a pressing mechanism located on the left and right sides, and the pressing mechanism includes a hydraulic rod and a clamping mechanism. The upper surface of the base plate has a moving groove on the left and right sides of the front side. Above the two sets of moving grooves is a placement platform for placing the protective shell. The front side of the placement platform is driven by an electric push rod.

[0008] In a preferred embodiment, a motor is mounted on the rear right side of the upper surface of the base plate, and the left side of the motor is connected to a lead screw via a coupling.

[0009] In a preferred embodiment, a mounting base is installed on the rear left side of the upper surface of the base plate, and a bearing is embedded in the right side of the mounting base, with the left side of the lead screw installed inside the bearing.

[0010] In a preferred embodiment, a movable base is installed on the outer side of the lead screw, and an internal thread groove matching the thread specification of the outer side of the lead screw is opened on the inner side of the movable base. The front side of the movable base is fixed to the rear side of the fixed sleeve by a connecting rod.

[0011] In a preferred embodiment, the right side of the upper surface of the fixed sleeve is fixed to the right side of the lower surface of the fixed block by a connecting post, and a telescopic hole matching the specifications of the push rod is opened at the center of the top of the fixed block.

[0012] In a preferred embodiment, the push rod passes through the telescopic hole and extends into the glue-applying cylinder. A push plate is provided at the bottom of the push rod, and the top of the push rod is fixed to the lower surface of the sliding base. A return spring is sleeved on the outside of the push rod above the fixing block.

[0013] In a preferred embodiment, the sliding base is hinged to the slider, the slider has a T-shaped structure, and the shape of the slider matches the shape of the groove.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up an adhesive application assembly, which includes an adhesive application cylinder, a push rod, and a sliding base, in actual use, the lead screw rotates under the drive of the motor and is threadedly connected to the inner side of the moving base, thereby driving the moving base to move. The moving base drives the fixed sleeve and the adhesive application cylinder to move. The movement of the adhesive application cylinder drives the sliding base to move through the push rod. When the adhesive application assembly moves from right to left along the bottom of the bracket, the push rod drives the push plate to move downward inside the adhesive application cylinder and evenly applies the sealant inside the adhesive application cylinder to the joint of the protective shell. Since several sets of balls are embedded in the lower surface of the slider and the left side of the lead screw is installed inside the bearing, the friction can be significantly reduced when the adhesive application assembly moves, thereby effectively weakening the vibration generated during the movement. The fixed sleeve, connecting rod, and moving base can limit the adhesive application assembly, so that it is always in front of the lead screw and moves along the bottom of the bracket. Therefore, the final effect is to effectively prevent the occurrence of breakpoints or adhesive seam offset during the adhesive application process.

[0015] 2. By setting a return spring and a fixing block, the top of the push rod passes downward through the telescopic hole opened on the top of the fixing block, and a return spring is sleeved on the outside of the push rod above the fixing block. In actual use, when the glue application assembly moves from right to left along the bottom of the bracket under the transmission of the screw, the push rod and push plate move downward inside the glue application cylinder, squeezing out the sealant inside the glue application cylinder. At the same time, the return spring and the fixing block press upward, making the downward movement of the push rod and push plate more stable. When the screw reverses, the moving base drives the glue application assembly to move from left to right along the bottom of the bracket through the connecting rod. At this time, since the top of the bracket is a slope structure with a gradually increasing slope from left to right, the return spring rebounds, causing the push rod to drive the push plate to move upward inside the glue application cylinder, thus completing one glue application operation. Therefore, the final effect is that automatic glue application can be completed with a simple structure, which greatly reduces the friction between the machines. The setting of the return spring can make the movement of the push rod and push plate more stable, thereby improving the uniformity of sealant extrusion. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As the first embodiment of this utility model: a protective shell sealant coating and pressing integrated machine, including: a coating component 200, the coating component 200 including a movable base 270 for driving the coating cylinder 210 to move, a fixed sleeve 220 fixed on the outside of the coating cylinder 210, and a fixed block 230 installed above the coating cylinder 210.

[0027] A push rod 240 is installed inside the fixed block 230. The push rod 240 extends into the glue applicator 210 below and is connected to the sliding base 260 above. A slider 261 is provided above the sliding base 260. The slider 261 is slidably installed in the groove 111 opened on the lower surface of the bracket 110. Several sets of balls 262 are embedded in the front and rear positions of the lower surface of the slider 261.

[0028] The bracket 110 is located above the adhesive application assembly 200. The bracket 110 has a U-shaped structure. The top of the bracket 110 is a sloping structure with a gradually increasing slope from left to right. A base plate is provided below the bracket 110, and the base plate is installed inside the main body 100 of the device.

[0029] The device body 100 has a pressing mechanism located on the left and right sides inside. The pressing mechanism includes a hydraulic rod and a clamping mechanism. A movable slot is opened on the left and right sides of the front surface of the bottom plate. Above the two movable slots is a placement platform 300 for placing the protective shell. The front side of the placement platform 300 is driven by an electric push rod 240.

[0030] A motor 120 is installed on the rear right side of the upper surface of the base plate, and the left side of the motor 120 is connected to the lead screw 121 via a coupling.

[0031] A mounting base 130 is installed on the rear left side of the upper surface of the base plate. A bearing is embedded in the right side of the mounting base 130, and the left side of the lead screw 121 is installed inside the bearing.

[0032] A movable base 270 is installed on the outside of the lead screw 121. The inner side of the movable base 270 is provided with an internal thread groove that matches the thread specification of the lead screw 121. The front side of the movable base 270 is fixed to the rear side of the fixed sleeve 220 by a connecting rod.

[0033] The sliding base 260 is hinged to the slider 261, which has a T-shaped structure and the shape of the slider 261 matches the shape of the groove 111.

[0034] In actual use, the glue application assembly 200 is located on the far right below the bracket 110. The glue application cylinder 210 contains sealant. The protective shell to be glued is placed inside the placement platform 300, with the seam of the protective shell facing upwards and in a horizontal position. The seam is coplanar with the bottom of the glue application cylinder 210. The motor 120 drives the lead screw 121 to rotate clockwise through the central control mechanism inside the main body 100. The left side of the lead screw 121 is located inside the bearing, which effectively reduces the vibration generated when the lead screw 121 rotates. The rotation of the lead screw 121 is threadedly connected to the inner side of the movable base 270, thereby driving the movable base 270 to move from right to left. Then, through the connecting rod, the fixed sleeve 220 and the glue application cylinder 210 move to the left. The fixed sleeve 220 and the fixed block 230 are connected by a connecting column, so the fixed block 230 drives the push rod 240 to move to the left. Since the top of the bracket 110 is a slope structure that gradually rises from left to right, when the glue application assembly 200 moves to the left, the push rod 240 drives the push plate to move downward inside the glue application cylinder 210 and squeezes the sealant through the bottom of the glue application cylinder 210, thereby applying the sealant to the joint. After the glue application is completed, the placement platform 300 moves forward along the two sets of moving grooves under the traction of the electric push rod 240, and performs the pressing work on the protective shell through the two sets of pressing mechanisms (the pressing mechanism and the motor 120 are existing technologies, and their structure and working principle will not be described in detail here).

[0035] It should be noted that when the top of the bracket 110 is tilted at an angle of 15 degrees and the glue applicator 210 is at its lowest side below the bracket 110, the distance between the bottom of the glue applicator 210 and the joint is 1 cm. When the glue applicator 210 moves to the leftmost side of the joint, there is still a gap between the bottom of the glue applicator 210 and the joint. That is, the bottom of the glue applicator 210 will not collide with the contact point during the leftward movement. During the movement of the glue applicator assembly 200, the slider 261 slides to the left along the inside of the groove 111. Since the slider 261 is hinged to the top of the sliding base 260, the slider 261 can adjust its angle according to the tilt angle of the groove 111. Therefore, several sets of balls 262 always roll along the back and forth position of the inner lower surface of the groove 111, which greatly reduces the friction of the slider 261 inside the groove 111. Therefore, the final effect is to effectively prevent the occurrence of breakpoints or glue seam offset during the glue application process.

[0036] Please see Figures 1-5 As a second embodiment of this utility model: based on the description in the above embodiments, further, the right side of the upper surface of the fixing sleeve 220 is fixed to the right side of the lower surface of the fixing block 230 by a connecting post, and a telescopic hole matching the specifications of the push rod 240 is opened at the center of the top of the fixing block 230.

[0037] The push rod 240 passes through the telescopic hole and extends into the glue applicator 210. A push plate is provided at the bottom of the push rod 240. The top of the push rod 240 is fixed to the lower surface of the sliding base 260. A return spring 250 is sleeved on the outside of the push rod 240 above the fixing block 230.

[0038] In actual use, when the glue application assembly 200 moves to the left, the push rod 240 and the push plate move downward inside the glue application cylinder 210 and squeeze out the sealant. This step is described in detail in Embodiment 1 and will not be repeated here. At the same time, since the fixed cylinder and the fixed sleeve 220 are connected and fixed, and the fixed sleeve 220 is fixed to the movable base 270 through the connecting rod, and the movable base 270 is sleeved on the outside of the lead screw 121, the position of the lead screw 121 remains unchanged. Therefore, when the glue application assembly 200 moves to the left, the fixed block 230 moves upward and squeezes the return spring 250 to compress and store force, thereby making the downward movement of the push rod 240 and the push plate more stable. After the glue application is completed, the glue application assembly 200 moves to the right. At this time, the push rod 240 and the push plate move upward inside the glue application cylinder 210, and the return spring 250 rebounds. Therefore, the final effect is that the setting of the return spring 250 can make the movement of the push rod 240 and the push plate more stable, thereby improving the uniformity of sealant extrusion.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
