Description

Technical Field

[0001] The present invention relates to the field of production and manufacturing of electrical components, and specifically to a relay potting and encapsulation processing device. Background Art

[0002] The relay contains many precision mechanical components and electrical elements inside, such as coils, contacts, etc. Through potting and encapsulation, these components can be isolated from the external environment, thereby effectively preventing the intrusion of harmful substances and ensuring the normal operation of the internal components of the relay.

[0003] Currently, automatic potting equipment is generally used to pot and encapsulate relays. First, the operator fixedly installs the jig with the relay on the base of the automatic potting equipment. Subsequently, the automatic potting equipment automatically moves a number of syringes thereon to the upper part of the relay, and the glue is injected into the relay one by one at a constant speed and fixed quantity through the syringes. Then, the operator moves the jig to the vacuum box for exhaust treatment, so that the bubbles inside the glue expand and escape, thereby improving the potting quality.

[0004] However, the above potting method will cause the relays potted first to wait on the jig for a long time, resulting in the glue on the relays potted first to be initially cured, making it difficult for the gas inside the glue to escape, reducing the exhaust treatment effect and affecting the encapsulation quality. In addition, due to the poor fluidity of the glue, the existing method of filling the inside of the relay by the gravity and fluidity of the glue itself is prone to the situation that the glue cannot fill the voids inside the relay, resulting in voids in the potting and encapsulation, further affecting the encapsulation quality.

[0018] The beneficial effects of the present invention are as follows: 1. While the glue injection tube is injecting glue into the relay, the present invention extends a vibration rod into the interior of the relay and vibrates the glue therein. By vibrating the glue, on the one hand, the flow of the glue can be accelerated, making it easier for the glue to fill the interior of the relay. On the other hand, the bubbles in the glue can be discharged, thereby pre-exhausting the glue to avoid poor exhaust effect in the later stage due to solidification of the glue.

[0019] 2. The present invention adopts a moving component that can move the vibration rod left and right when the vibration rod vibrates the glue, so that the vibration rod can come into contact with more glue, thereby improving the fluidity and exhaust effect of the glue. The vibration rod can move back and forth up and down while moving left and right, so that the vibration rod can continuously bring the bubbles inside the glue out of the glue, further improving the pre-exhaust effect.

[0020] 3. The present invention adopts a spiral spring to instantly push the push column upward through its own elastic force, so that the push column instantly pushes the relay filled with glue upward, so that the glue inside the relay moves downward relative to the relay under the action of its own inertia, and then the glue can fill the interior of the relay, further improving the filling effect of the glue, preventing gaps in the glue-filled package, and ensuring the packaging quality.

[0021] Fourth, after the push column in the present invention pushes the relay, it can also pull the relay downward, so that negative pressure is formed between the upper part of the shielding cover and the relay, so that the bubbles inside the glue in the relay expand and escape, further improving the effect of pre-exhaust, thereby improving the potting quality.

[0022] 5. The present invention adopts a drip-proof component to absorb and recover the glue adhered to the outer side of the vibration rod, which not only prevents the glue from dripping and ensures clean operation, but also prevents the glue from being wasted. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The embodiments of the present invention will be described in detail below. The described embodiments are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0034] Refer to Figure 1 and Figure 2, A relay potting and encapsulation processing device, including a base 1, a rectangular frame 2 driven by electricity is slidably arranged in the front and back directions on the upper part of the base 1, a jig 3 for holding the relay is fixedly installed on the upper part of the base 1 in a detachable manner, a degassing mechanism 4 for assisting in pre-exhausting the glue is arranged on the rectangular frame 2, and a filling mechanism 5 for making the glue fully fill the inside of the relay is also arranged on the rectangular frame 2.

[0035] When it is necessary to pot and encapsulate the relay, first, the relay is fixedly installed on the upper part of the jig 3, then the operator fixedly installs the jig 3 on the upper part of the base 1. After that, the operator drives the degassing mechanism 4 through the rectangular frame 2 to inject glue into the relay in batches, and at the same time vibrates the glue inside the relay. At the same time, the rectangular frame 2 drives the filling mechanism 5 to push the relay filled with glue, so that the glue inside the relay fills the entire inside of the relay under the action of its own gravity. Then the filling mechanism 5 can also perform negative pressure exhaust on the relay.

[0036] Continue to refer to Figure 1 and Figure 2 , The jig 3 includes a bottom plate 31 fixedly installed on the upper part of the base 1 in a detachable manner. A number of placing blocks 32 that are slidably connected to it in the up and down direction are arranged at equal intervals along the front and back directions on the bottom plate 31. A number of workstations are arranged at equal intervals along the left and right directions on the placing blocks 32.

[0037] When it is necessary to pot and encapsulate the relay, the operator inserts the relays into the workstations of the placing blocks 32 respectively, and at the same time makes the openings of the relays that need to be injected with glue face upward. Then the operator fixedly installs the bottom plate 31 connected with the relays on the upper part of the base 1.

[0038] In this embodiment, the workstations on the placing blocks 32 are in the shape of rectangular grooves. The relay is inserted into the inside of the rectangular groove, so that the relay can be connected to the placing block 32. In addition, multiple existing clamping structures can also be arranged on the placing block 32 for use as the workstations on the placing block 32. The clamping structure is composed of two synchronously and reversely moving clamping plates. By clamping the two sides of the relay with the clamping plates, the relay can be connected to the placing block 32.

[0039] Refer to 1, Figure 2 , Figure 3 and Figure 4 , The degassing mechanism 4 includes a C-shaped plate 41 fixedly installed on the lower side of the front part of the top wall of the rectangular frame 2. A number of glue injection tubes 42 are fixedly installed at equal intervals along the left and right directions on the lower part of the C-shaped plate 41. The degassing mechanism 4 also includes an anti-drip component 44. The anti-drip component 44 includes a glue storage tank 443 fixedly installed on the upper rear side of the horizontal section on the lower side of the C-shaped plate 41. The glue storage tank 443 is communicated with the glue injection tubes 42.

[0040] In the initial state, the rectangular frame 2 is located at the rear position of the base 1. When the base plate 31 carrying the relay is fixedly installed on the base 1, the glue injection tubes 42 are respectively directly above the stations on the last placing block 32.

[0041] It should be noted that the glue injection tubes 42 in this embodiment are equipped with electromagnetic valves. By controlling the opening of the electromagnetic valves, the glue in the glue storage tank 443 can be discharged through the glue injection tubes 42, and vice versa, the glue injection tubes 42 can be prevented from discharging glue.

[0042] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in, on the upper front side of the horizontal section at the lower side of the C-shaped plate 41, a moving member 45 is slidably arranged left and right. The moving member 45 is connected through a moving assembly 43 to a vibrating rod 46 corresponding to the glue injection tube 42 one by one. The moving assembly 43 includes a follower plate 431 slidably arranged up and down on the upper part of the moving member 45 through a plug post. The rear side of the follower plate 431 is fixedly connected through a rubber sleeve rod 432 to a vibrating plate 433. A vibrating motor 437 is fixedly installed on the upper part of the vibrating plate 433. The lower part of the vibrating plate 433 is fixedly connected together with all the vibrating rods 46. A track groove 434 is opened on the rear side of the vertical section of the C-shaped plate 41. The front part of the follower plate 431 slides inside the track groove 434 through a protruding post.

[0043] Refer to Figure 3 、 Figure 4 and Figure 6 As shown in, the left side of the track groove 434 has a vertical section structure, and the right side of the track groove 434 has a wavy section structure. A first electric push rod 435 is fixedly installed on the upper side of the follower plate 431. A second electric push rod 436 is fixedly installed on the left side of the C-shaped plate 41. The telescopic section of the second electric push rod 436 is fixedly connected to the moving member 45.

[0044] In the initial state, the telescopic section of the first electric push rod 435 is in the extended state, so that the telescopic section of the first electric push rod 435 pushes the moving member 45 downward. The moving member 45, through the reaction force on the first electric push rod 435, pushes the follower plate 431 to a position away from the moving member 45, so that the moving member 45 drives the vibrating plate 433 through the rubber sleeve rod 432 to also be in a position away from the moving member 45. The vibrating plate 433 drives the lower end of the vibrating rod 46 to be flush with the lower end of the glue injection tube 42.

[0045] After the base plate 31 carrying the relay is fixedly installed on the base 1, the telescopic section of the first electric push rod 435 is fully retracted, so that the follower plate 431 moves downward under the action of gravity. The follower plate 431 moves along the vertical section structure of the track groove 434 through the protruding columns thereon until the protruding columns move to the lower end of the vertical section structure of the track groove 434, thereby causing the follower plate 431 to drive the vibrating rod 46 to extend downward into the relay.

[0046] After the vibrating rod 46 extends into the relay, start the vibrating motor 437 to drive the vibrating plate 433 to start vibrating. The vibrating plate 433 drives the vibrating rod 46 to vibrate synchronously. Subsequently, glue in the glue storage tank 443 is injected into the relay through the glue injection pipe 42, so that the glue is vibrated by the vibrating rod 46 while flowing inside the relay, thereby increasing the fluidity of the glue and making it easier for the glue to fill the inside of the entire relay. At the same time, the vibrating rod 46 discharges the air bubbles inside the glue through vibration.

[0047] While the glue injection pipe 42 is discharging glue, reciprocally extend and retract the telescopic section of the second electric push rod 436, so that the second electric push rod 436 first pushes the moving part 45 to the right. The moving part 45 drives the follower plate 431 to move to the right synchronously, thereby causing the follower plate 431 to drive the protruding columns thereon to move along the wavy section structure of the track groove 434, and further causing the track groove 434 to push it to move up and down reciprocally when the follower plate 431 moves horizontally left and right.

[0048] The follower plate 431 drives the vibrating rod 46 to move horizontally left and right and up and down reciprocally, so that the vibrating rod 46 can contact more glue, thereby improving the fluidity of the glue and the exhaust effect. At the same time, the vibrating rod 46 can continuously bring the air bubbles inside the glue out to the outside of the glue, further improving the pre-exhaust effect.

[0049] After the glue injection is completed, stop the glue injection pipe 42 from discharging glue. At the same time, retract the telescopic section of the second electric push rod 436 to drive the moving part 45 to move to the initial position on the left. Subsequently, extend the telescopic section of the first electric push rod 435 to drive the vibrating rod 46 to move up to the initial height position.

[0050] Refer to Figure 4 and Figure 5 As shown in, the drip-proof assembly 44 further includes glue suction pipes 441 fixedly installed at equal intervals in the left-right direction on the lower side of the moving part 45. The glue suction pipes 441 are located outside the coaxial line of the vibrating rods 46 at corresponding positions. The vibrating rods 46 pass through the sealing rubber sleeves 442 provided on the moving part 45 to the inside of the glue suction pipes 441. A flow channel 444 communicating with all the glue suction pipes 441 is opened inside the moving part 45. An electric pump 445 is fixedly installed on the upper right side of the horizontal section of the lower side of the C-shaped plate 41. The electric pump 445 is communicated with the flow channel 444 and the glue storage tank 443 through pipelines.

[0051] When the vibration rod 46 moves up to the initial height position, the vibration rod 46 is completely retracted inside the glue suction tube 441, and then the electric pump 445 is started to pump air into the glue suction tube 441, so that the glue suction tube 441 draws the glue adhered to the outside of the vibration rod 46 into the glue storage box 443, thereby preventing the glue from dripping and keeping the operation clean. At the same time, the glue is recycled to avoid waste.

[0052] See also Figure 1 , Figure 2 and Figure 7 The filling mechanism 5 includes a shielding cover 51 which is arranged at the rear lower side of the top wall of the rectangular frame 2 and slides up and down through a guide column. A hydraulic rod 56 for driving the shielding cover 51 to move up and down is fixedly installed on the upper part of the rectangular frame 2. A cover plate 52 is arranged inside the shielding cover 51 and slides up and down through a guide rod. A push spring is arranged between the cover plate 52 and the shielding cover 51.

[0053] When the vibration rod 46 is completely retracted inside the glue suction tube 441, the rectangular frame 2 moves forward to drive the glue injection tube 42 to move forward to the upper part of the next placement block 32, so that the glue injection tube 42 can inject glue into the relay on the next placement block 32. At the same time, the rectangular frame 2 drives the shielding cover 51 to move to the upper side of the last placement block 32, so that the shielding cover 51 is located directly above the relay that has just been filled with glue. Then, the telescopic section of the hydraulic rod 56 is extended to drive the shielding cover 51 to move downward to the outside of the last placement block 32, and the lower end of the shielding cover 51 is against the upper part of the bottom plate 31.

[0054] The shielding cover 51 drives the cover plate 52 to move downward synchronously through the push spring. When the lower end of the shielding cover 51 abuts against the upper part of the base plate 31, the cover plate 52 seals on the upper end of the relay, thereby sealing the glue inside the relay to a certain extent. At the same time, the reaction force of the relay on the cover plate 52 pushes the cover plate 52 to move upward a certain distance relative to the shielding cover 51, so that the cover plate 52 pre-compresses the push spring to a certain extent.

[0055] It should be noted that a slot is provided on the cover plate 52 for the pins of the relay to pass through, and the opening of the slot on the cover plate 52 is larger than the pins of the relay. On the one hand, this allows the pins bent to a certain extent to pass through the slot, and on the other hand, it allows the gas in the glue inside the relay to escape through the slot.

[0056] Continue reading Figure 1 , Figure 2 and Figure 7 A one-way air valve 511 is fixedly installed on the upper part of the shielding cover 51, a plurality of ventilation holes are opened at the lower part of the shielding cover 51, a sealing frame 512 is fixedly installed at the middle part of the outer side of the placement block 32, and a chamfer is opened on the upper part of the sealing frame 512.

[0057] When the lower end of the shielding cover 51 abuts against the upper part of the base plate 31, the inner side surface of the shielding cover 51 fits tightly against the outer side surface of the sealing frame 512 at the corresponding position, so that the space between the upper part of the sealing frame 512 and the top plate of the shielding cover 51 is sealed. The shielding cover 51 can be guided by the chamfer on the sealing frame 512, so that the shielding cover 51 can be more smoothly covered on the outside of the sealing frame 512.

[0058] See also Figure 1 , Figure 2 and Figure 8 A fixed frame 53 is fixedly installed on the upper side of the bottom wall of the rectangular frame 2, a pushing column 54 is set on the rear part of the fixed frame 53 for sliding up and down, a coil spring is set between the pushing column 54 and the fixed frame 53, a square tube 551 is set on the rear side of the front vertical section of the fixed frame 53 for sliding up and down, a pulling block 552 is set on the rear side of the square tube 551 for sliding back and forth, a compression spring is set between the pulling block 552 and the square tube 551, and a protruding block 553 is fixedly installed on the front side of the lower part of the pushing column 54.

[0059] See also Figure 2 and Figure 8 A No. 3 electric push rod 55 is fixedly installed on the front side of the lower part of the fixed frame 53, the square tube 551 is fixedly connected to the telescopic section of the No. 3 electric push rod 55, the elastic force of the push spring is smaller than that of the coil spring, a chamfer is provided on the upper rear side of the pulling block 552, a chamfer is provided on the lower front side of the raised block 553, a triangular block 554 with an inclined surface facing backwards is fixedly installed on the right side of the pulling block 552, and a trapezoidal block 555 with an inclined surface facing forwards is fixedly installed on the fixed frame 53.

[0060] See also Figure 8 Two connecting buckles 541 arranged front and back are provided inside the push column 54 for sliding, a return spring is provided between the two connecting buckles 541, the upper part of the connecting buckle 541 is a right-angled trapezoidal structure, and the lower part of the connecting buckle 541 is an isosceles triangle structure, and the lower part of the placing block 32 is provided with a stepped groove 542 with a small lower diameter and a large upper diameter.

[0061] In the initial state, the inclined surface of the triangular block 554 is attached to the inclined surface of the trapezoidal block 555, and at the same time, the lower side surface of the pulling block 552 is against the upper side surface of the protruding block 553, so that the pushing column 54 is close to the lower side surface of the fixed frame 53, and at the same time, the coil spring is in a compressed state, and the upper end surface of the pushing column 54 is located on the lower side of the bottom plate 31.

[0062] When the lower end of the shielding cover 51 abuts against the upper part of the base plate 31, the telescopic section of the No. 3 electric push rod 55 is retracted to drive the pulling block 552 to move downward through the square tube 551, so that the pulling block 552 drives the triangular block 554 to move along the inclined surface of the trapezoidal block 555, so that while the triangular block 554 moves downward, the trapezoidal block 555 pushes the triangular block 554 forward, and then the triangular block 554 drives the pulling block 552 to move forward to the front side of the protruding block 553. At this time, the pulling block 552 no longer blocks the protruding block 553.

[0063] Under the push of its own elastic force, the coil spring drives the upper end of the pushing column 54 to move quickly to the inside of the stepped groove 542 of the last placement block 32, and then the pushing column 54 drives the last placement block 32 to move upward synchronously, and the last placement block 32 drives the relay on it to move upward synchronously and quickly, so that the glue inside the relay moves downward relative to the relay under the action of its own inertia, so that the glue can fill the inside of the relay, further improving the filling effect of the glue, preventing gaps in the glue-filled package, and ensuring the packaging quality.

[0064] At the same time, when the upper end of the pushing column 54 extends into the stepped groove 542, the stepped groove 542 first pushes the connecting buckle 541 toward the inside of the pushing column 54 through its lower edge, and compresses the return spring at the same time. When the upper end of the pushing column 54 abuts against the placement block 32, the return spring pushes the connecting buckle 541 to extend to the outside of the pushing column 54 through its own elastic force, so that the lower horizontal section of the right-angled trapezoidal structure of the connecting buckle 541 abuts against the small diameter step section of the stepped groove 542, thereby connecting and locking the pushing column 54 and the last placement block 32 into a whole.

[0065] When the last placement block 32 moves upward, the last placement block 32 drives the sealing frame 512 thereon to push the air on the upper part of the shielding cover 51 from the one-way air valve 511 to the outside of the shielding cover 51. At the same time, the space under the sealing frame 512 of the shielding cover 51 is evacuated through the vent holes on the shielding cover 51, thereby ensuring that the placement block 32 moves upward smoothly in the shielding cover 51.

[0066] When the thrust of the pushing column 54 is exhausted, due to the friction between the shielding cover 51 and the sealing frame 512 and the thrust of the coil spring on the last placement block 32 through the pushing column 54, the last placement block 32 will not fall under the action of gravity. At this time, the pushing column 54 drives the isosceles triangle structure of the connecting buckle 541 to move up to the upper side of the fixed frame 53, and then extends the telescopic section of the No. 3 electric push rod 55 to drive the pulling block 552 to move up to the upper side of the protruding block 553, and then retracts the telescopic section of the No. 3 electric push rod 55 to pull the pushing column 54 downward.

[0067] The push column 54 pulls the last placement block 32 to move downward synchronously through the connecting buckle 541, so that a negative pressure is formed inside the shielding cover 51 between the sealing frame 512 and the top plate of the shielding cover 51, so that the bubbles inside the glue in the relay expand and escape, further improving the pre-exhaust effect and improving the potting quality.

[0068] When the pushing column 54 pulls the placement block 32 downward until its bottom is attached to the bottom plate 31, the isosceles triangle structure of the connecting buckle 541 moves to the inside of the upper horizontal section of the fixed frame 53, so that the fixed frame 53 pushes the connecting buckle 541 to the inside of the pushing column 54, thereby disengaging the locking between the pushing column 54 and the placement block 32, and then continues to retract the telescopic section of the No. 3 electric push rod 55 to pull the pushing column 54 downward to the initial position, and then moves the rectangular frame 2 forward again to perform the glue filling and packaging operation on the remaining relays.

[0069] See also Figure 1-Figure 8 When the relay is encapsulated by glue filling, the present invention also includes the following steps: In the first step, the operator inserts the relays into the workstations of the placement block 32 respectively, and makes the opening of the relay that needs to be injected with glue face upward, and then the operator fixes the bottom plate 31 connected to the relay on the upper part of the base 1.

[0070] The second step is to completely retract the telescopic section of the No. 1 electric push rod 435 so that the follower plate 431 drives the vibration rod 46 to extend downward into the interior of the relay, start the vibration motor 437 to drive the vibration rod 46 to vibrate, and then inject glue into the interior of the relay through the glue injection tube 42.

[0071] The third step is to reciprocate and extend the telescopic section of the No. 2 electric push rod 436, so that the vibration rod 46 can move horizontally to the left and right and reciprocate up and down, so that the vibration rod 46 can come into contact with more glue, thereby improving the fluidity of the glue and the exhaust effect, and at the same time, the vibration rod 46 can continuously bring the bubbles inside the glue out of the glue.

[0072] The fourth step is to stop the glue injection tube 42 from discharging glue after the glue injection is completed, move the vibration rod 46 to the inside of the glue suction tube 441, start the electric pump 445 to pump air into the glue suction tube 441, so that the glue suction tube 441 can draw the glue adhered to the outside of the vibration rod 46 to the inside of the glue storage box 443, thereby preventing the glue from dripping and keeping the operation clean. At the same time, the glue can be recycled to avoid waste.

[0073] The fifth step is to move the rectangular frame 2 forward to drive the glue injection tube 42 to the upper part of the next placement block 32, so that the glue injection tube 42 can inject glue to the relay on the next placement block 32, and at the same time drive the shielding cover 51 to move to the upper side of the last placement block 32, and extend the telescopic section of the hydraulic rod 56 to drive the lower end of the shielding cover 51 to rest against the upper part of the bottom plate 31, and the shielding cover 51 drives the cover plate 52 to cover the upper end of the relay through the push spring.

[0074] The sixth step is to retract the telescopic section of the No. 3 electric push rod 55 to drive the pulling block 552 to no longer block the protruding block 553, so that the spiral spring drives the pushing column 54 to push the relay to move up synchronously and quickly, so that the glue inside the relay moves downward relative to the relay under the action of its own inertia, so that the glue can fill the interior of the relay, further improving the filling effect of the glue.

[0075] The seventh step is to retract the telescopic section of the third electric push rod 55 and pull the last placement block 32 downward, so that a negative pressure is formed inside the shielding cover 51 between the sealing frame 512 and the top plate of the shielding cover 51, so that the bubbles inside the glue in the relay expand and escape, further improving the effect of pre-exhaust and improving the potting quality. Then the rectangular frame 2 is moved forward again to perform the glue potting and packaging operation on all the relays.

[0076] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
