Electric bicycle charging plug multi-station automatic assembly equipment

Abstract

This invention discloses a multi-station automatic assembly equipment for electric bicycle charging plugs, belonging to the field of charging plug production equipment, including an assembly table and a conveyor belt. This solution uses a sleeve; after assembly, the output ends of the electric push rod and the electric telescopic rod retract and reset. During the retraction of the electric push rod's output end, it drives the mounting plate upward. During this upward movement, airflow from the telescopic tube flows through the first air pipe and the adjusting component into the sleeve, increasing the pressure within the sleeve. Under this pressure, the mounting rod drives the push plate to move. At this time, the first spring is compressed and has a tendency to return to its original position. During the push plate's movement, it pushes the assembled charging plug towards the first conveyor belt, achieving linkage between mechanical pressing assembly and pneumatic unloading within the same reciprocating stroke. This shortens the single assembly cycle and eliminates the cycle stagnation and potential safety hazards caused by manual intervention.

Description

Technical Field

[0001] This invention relates to the field of charging plug manufacturing equipment, and more specifically, to a multi-station automatic assembly equipment for electric bicycle charging plugs. Background Technology

[0002] In practice, after the electric bicycle charging plug terminal is manufactured, the positioning pin needs to be installed and fixed to complete the subsequent positioning and connection with the charging equipment.

[0003] Traditional charging plug assembly involves numerous steps, each performed independently, making multi-station assembly impossible. It also requires excessive manual labor, resulting in low production efficiency and a large workload. Furthermore, the excessive manual labor leads to low assembly precision of the charging plugs, affecting product quality.

[0004] To address the aforementioned issues, some solutions have been proposed in existing technologies. For example, Chinese utility model patent CN216681024U discloses an automatic assembly device for positioning pins of automotive charging plugs. This device adjusts the threaded head of the positioning pin to press against a rotating table, inserts the lower end of the charging plug into the inner diameter of the rotating table's ring, and rotates the charging plug to engage its flat cut with the rotating table's flat locking block. Rotating the locking block positions its lower surface on the charging plug's annular flange, thus completing the positioning of the charging plug. Furthermore, by setting multiple workstations, assembly can be performed simply by inserting the plug sequentially into the rotating table. While existing devices can improve production efficiency to some extent, they still have limitations: after assembly, the assembled charging plugs need to be manually removed from the workstations before new charging plugs can be inserted, significantly impacting production efficiency. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a multi-station automatic assembly equipment for electric bicycle charging plugs, which can automatically remove assembled charging plugs, thereby effectively improving production efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An automatic assembly equipment for electric bicycle charging plugs with multiple workstations includes an assembly table and a conveyor belt. An electric rotating ring is rotatably mounted on the top wall of the assembly table. The electric rotating ring is provided with a clamping component for clamping the charging plug. A top plate is fixedly mounted on the assembly table. An electric push rod is fixedly mounted on the top plate. An mounting plate is fixedly mounted on the output end of the electric push rod. An assembly component is provided on the mounting plate. An unloading component is provided on the electric rotating ring. The unloading assembly includes a sleeve uniformly fixedly mounted on an electric rotating ring. An installation rod is slidably and sealed inside the sleeve, and a first spring is installed between the installation rod and the sleeve. A push plate is fixedly mounted at the end of the installation rod away from the first spring. A first conveyor belt that cooperates with the push plate is mounted on the assembly platform. A telescopic tube is installed between the installation plate and the top plate. An adjustment assembly is provided on the assembly platform, and a first air pipe connected to the adjustment assembly is inserted into the installation plate. The first air pipe is connected to the sleeve through the adjustment assembly, and the end of the first air pipe away from the adjustment assembly is connected to the telescopic tube.

[0008] Furthermore, the assembly includes an electric slide rail fixedly mounted on the bottom wall of the mounting plate, a mounting block slidably mounted on the electric slide rail, an electric bidirectional threaded rod rotatably mounted on the mounting block, a clamping plate symmetrically slidably mounted on the mounting block to cooperate with the conveyor belt, and the clamping plate threadedly engaged with the electric bidirectional threaded rod, and a first electric telescopic rod with its output end pointing downwards fixedly mounted on the mounting block, and an air inlet valve with its output end communicating with the telescopic pipe fixedly mounted on the top plate.

[0009] Furthermore, the adjustment assembly includes a mounting cylinder fixedly installed on the assembly table, and the end of the first air pipe away from the telescopic tube is connected to the mounting cylinder. An annular plate is fixedly installed on the electric rotating ring, which is in a rotating and sealing fit with the mounting cylinder. Vertical grooves that cooperate with the sleeve are evenly opened on the annular plate. An arc-shaped plate is vertically slidably installed in the vertical groove, and a third spring is installed between the arc-shaped plate and the annular plate. A first connecting hole is opened on the side wall of the mounting cylinder located on the side of the first conveyor belt. A second connecting hole communicating with the first connecting hole is opened on the arc-shaped plate. A second air pipe communicating with the second connecting hole is inserted into the sleeve.

[0010] Furthermore, an electromagnet is fixedly installed on the electric rotating ring, and a magnet block that repels the electromagnet is fixedly installed on the arc-shaped plate. An electrical contact that mates with the charging plug is fixedly installed on the electric rotating ring, and the electromagnet is electrically connected to the electrical contact. A vertical rod is fixedly installed on the mounting plate, and an electrical plug is fixedly installed at the bottom end of the vertical rod. A fixing component for fixing the arc-shaped plate is provided on the annular plate, and a second conveyor belt that mates with the push plate is installed on the assembly table. A third connecting hole is opened on the side wall of the sleeve located on one side of the second conveyor belt.

[0011] Furthermore, the fixing component includes a connecting groove formed at the top of the arc-shaped plate, a fixing groove formed on the side wall of the connecting groove, a linkage plate uniformly and horizontally slidably installed on the top wall of the annular plate, and the top wall of the linkage plate is inclined, a fourth spring is installed between the linkage plate and the annular plate, a connecting rod is fixedly installed on the bottom wall of the linkage plate, and a fixing block is fixedly installed at the bottom end of the connecting rod, and an inclined groove is formed on the fixing block, and a release rod is fixedly installed on the bottom wall of the mounting plate.

[0012] Furthermore, a first linkage rod is fixedly installed on the bottom wall of the mounting plate, an electric circular slide rail is fixedly installed at the bottom end of the first linkage rod, a second electric telescopic rod is slidably installed on the electric circular slide rail, a glue applicator is fixedly installed on the output end of the second electric telescopic rod, a glue tank is fixedly installed on the top wall of the top plate, and a material conveying pipe communicating with the glue applicator is inserted into the glue tank.

[0013] Furthermore, a second linkage rod is fixedly installed on the bottom wall of the mounting plate, and a hollow ring is fixedly installed at the bottom end of the second linkage rod. Air holes are evenly opened on the hollow ring, and the bottom wall of the air holes forms a 60-degree angle with the vertical plane.

[0014] Furthermore, a gas spring is vertically slidably installed on the top plate, and a linkage spring is installed between the gas spring and the top plate. A ventilation groove is provided on the gas spring, and a third air pipe communicating with the ventilation groove is inserted into the hollow ring.

[0015] Furthermore, the clamping assembly includes grooves evenly formed on the electric rotating ring, a limiting block is slidably installed in the groove, a second spring is installed between the limiting block and the groove, and spring telescopic rods are symmetrically fixedly installed on the bottom wall of the mounting plate, with the output end of the spring telescopic rods being an inclined surface.

[0016] Furthermore, clamping blocks are symmetrically slidably mounted on the limiting block, and a return spring is installed between the clamping blocks and the limiting block, and the sidewalls of the two clamping blocks on adjacent sides are inclined surfaces.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) By setting up a sleeve, after the assembly is completed, the output end of the electric push rod and the electric telescopic rod retracts and resets. During the retraction of the output end of the electric push rod, the mounting plate moves upward. During the upward movement of the mounting plate, the airflow in the telescopic tube flows into the sleeve through the first air pipe and the adjustment component, and increases the pressure in the sleeve. Then, under the action of the pressure, the mounting rod drives the push plate to move. At this time, the first spring is compressed and has the tendency to recover. During the movement of the push plate, the charging plug after the assembly is completed is pushed to move onto the first conveyor belt. This realizes the linkage between mechanical pressing assembly and pneumatic unloading in the same reciprocating stroke, shortens the single assembly cycle, and eliminates the cycle stagnation and potential safety hazards caused by manual intervention. (2) This solution opens a first connecting hole and a third connecting hole on the mounting cylinder respectively. When the charging plug can be used normally, after the power plug is inserted into the charging plug, the electromagnet is energized and drives the arc plate to move upward through the magnet block, so that the second connecting hole on the arc plate moves up to the same height as the first connecting hole. When the charging plug cannot be used, the second connecting hole and the third connecting hole on the arc plate are at the same height. Since the first connecting hole and the third connecting hole are opened at the first conveyor belt and the second conveyor belt respectively, the charging plug that can be used normally can be pushed to the first conveyor belt and the charging plug that cannot be used normally can be pushed to the second conveyor belt. This forms a highly de-electronic mechanical pneumatic interlocking sorting logic, which greatly reduces the system's dependence on external complex sensor networks. It not only significantly improves the anti-interference operation stability of the equipment in strong electromagnetic interference or dust environment, but also reduces the overall energy consumption through internal pneumatic drive, realizing a truly inherently safe automatic flow. (3) In this solution, after the push plate pushes the charging plug, the air rod drives the ventilation groove to connect with the third air pipe. At this time, the first spring extends and drives the mounting rod to reset, and the airflow in the sleeve flows into the telescopic tube again, and flows into the third air pipe through the telescopic tube and ventilation groove. Then it flows into the hollow ring through the third air pipe and forms an annular micro airflow through the inclined air holes. It is precisely blown at the joint between the upper shell and the lower shell to blow away plastic particles or dust attracted by electrostatics at the joint before applying the adhesive, thereby significantly improving the bonding strength and waterproof yield of the subsequent sealant.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 12 An automatic multi-station assembly equipment for electric bicycle charging plugs includes an assembly table 101 and a conveyor belt 102. An electric rotating ring 103 is rotatably mounted on the top wall of the assembly table 101. The electric rotating ring 103 is provided with a clamping component for clamping the charging plug. A top plate 104 is fixedly mounted on the assembly table 101. An electric push rod 105 is fixedly mounted on the top plate 104. An mounting plate 106 is fixedly mounted on the output end of the electric push rod 105. An assembly component 3 is provided on the mounting plate 106. An unloading component 2 is provided on the electric rotating ring 103. The unloading assembly 2 includes a sleeve 201 uniformly fixedly installed on an electric rotating ring 103. An installation rod 202 is slidably and sealed inside the sleeve 201, and a first spring 203 is installed between the installation rod 202 and the sleeve 201. A push plate 204 is fixedly installed at the end of the installation rod 202 away from the first spring 203. A first conveyor belt 205 that cooperates with the push plate 204 is installed on the assembly table 101. A telescopic tube 206 is installed between the mounting plate 106 and the top plate 104. An adjustment assembly 4 is provided on the assembly table 101, and a first air pipe 207 that communicates with the adjustment assembly 4 is inserted into the mounting plate 106. The first air pipe 207 is connected to the sleeve 201 through the adjustment assembly 4, and the end of the first air pipe 207 away from the adjustment assembly 4 is connected to the telescopic tube 206.

[0022] The assembly component 3 includes an electric slide rail 301 fixedly mounted on the bottom wall of the mounting plate 106, a mounting block 302 slidably mounted on the electric slide rail 301, an electric bidirectional threaded rod 303 rotatably mounted on the mounting block 302, a clamping plate 304 symmetrically slidably mounted on the mounting block 302 to cooperate with the conveyor belt 102, and the clamping plate 304 and the electric bidirectional threaded rod 303 are threadedly engaged, a first electric telescopic rod 305 with its output end pointing downward is fixedly mounted on the mounting block 302, and an air inlet valve 306 with its output end communicating with the telescopic pipe 206 is fixedly mounted on the top plate 104.

[0023] In use, the user can first place the lower shell of the charging plug on the electric rotating ring 103. Simultaneously, the electric slide rail 301 moves the clamping plate 304 via the mounting block 302. When the clamping plate 304 moves above the conveyor belt, the electric bidirectional threaded rod 303 rotates, causing the two clamping plates 304 to move closer together. During this process, the two clamping plates 304 can clamp the upper shell of the charging plug with terminals above the conveyor belt. Then, the electric slide rail 301, through the mounting block 302 and the clamping plate 304, moves the upper shell of the charging plug to the electric rotating ring 103. Above 3, the electric rotating ring 103 then moves the lower shell directly below the upper shell. At this time, the output end of the electric push rod 105 extends and moves the mounting plate 106 downward. During the downward movement of the mounting plate 106, the upper shell moves downward, gradually contacting and inserting into the lower shell. At this time, the electric bidirectional threaded rod 303 reverses and moves the two clamping plates 304 away from each other. Then, the output end of the first electric telescopic rod 305 extends, pushing the upper shell completely into the lower shell and engaging it with the lower shell. During assembly, this causes... The operator can continue to place the new lower shell on the electric rotating ring 103, thus achieving the purpose of multi-station automatic assembly. Furthermore, by setting the telescopic tube 206, the mounting plate 106 can be horizontally limited, preventing it from shifting and affecting production efficiency. During the downward movement of the mounting plate 106, the telescopic tube 206 draws in air from the outside through the air inlet valve 306. After assembly, the electric push rod 105 and the output end of the first electric telescopic rod 305 retract and reset. During the retraction of the output end of the electric push rod 105, the mounting plate 106 is driven... As the mounting plate 106 moves upward, the airflow in the telescopic tube 206 flows through the first air pipe 207 and the adjusting component 4 into the sleeve 201, increasing the pressure inside the sleeve 201. Under the pressure, the mounting rod 202 drives the push plate 204 to move. At this time, the first spring 203 is compressed and has a tendency to recover. During the movement of the push plate 204, the charging plug that has finished assembling at the first conveyor belt 205 is pushed onto the first conveyor belt 205, thus eliminating the need for manual unloading by the operator and effectively improving production efficiency.

[0024] like Figure 3 , Figure 6 Figure 7 , Figure 8 , Figure 10As shown, the adjustment component 4 includes a mounting cylinder 401 fixedly mounted on the assembly table 101, and the end of the first air pipe 207 away from the telescopic pipe 206 is connected to the mounting cylinder 401. An annular plate 402 is fixedly mounted on the electric rotating ring 103 and rotates and seals with the mounting cylinder 401. Vertical grooves that cooperate with the sleeve 201 are evenly opened on the annular plate 402. An arc plate 403 is vertically slidably installed in the vertical groove. A third spring 404 is installed between the arc plate 403 and the annular plate 402. A first connecting hole 405 is opened on the side wall of the mounting cylinder 401 located on the side of the first conveyor belt 205. A second connecting hole 406 communicating with the first connecting hole 405 is opened on the arc plate 403. A second air pipe 407 communicating with the second connecting hole 406 is inserted into the sleeve 201.

[0025] An electromagnet 501 is fixedly installed on the electric rotating ring 103. A magnet block 502 that repels the electromagnet 501 is fixedly installed on the arc plate 403. An electrical contact 503 that mates with the charging plug is fixedly installed on the electric rotating ring 103. The electromagnet 501 is electrically connected to the electrical contact 503. A vertical rod 504 is fixedly installed on the mounting plate 106. An electrical plug 505 is fixedly installed at the bottom end of the vertical rod 504. A fixing component 6 for fixing the arc plate 403 is provided on the annular plate 402. A second conveyor belt 506 that mates with the push plate 204 is installed on the assembly table 101. A third connecting hole 507 is opened on the side wall of the sleeve 201 located on one side of the second conveyor belt 506.

[0026] By adopting the above technical solution, when the electric rotating ring 103 moves the unassembled lower shell to below the upper shell, the electric rotating ring 103 will drive the assembled charging plug to rotate below the power connector 505. Then, during the downward movement of the mounting plate 106, the mounting plate 106 drives the power connector 505 downward through the vertical rod 504. During the downward movement, the power connector 505 is gradually inserted into the charging plug. It should be noted that when the power connector 505 is inserted into the charging plug, the PLC controller determines the conduction state by detecting the feedback current signal of the power contact 503. When the charging plug can be used normally, the LC controller controls the electromagnet 501 to generate a magnetic field. The LC controller is a relatively mature existing technology and will not be described in detail here. Then, under the action of the electromagnetic field, the arc plate 403 drives the second connecting hole 406 to move upward. The third spring 404 is compressed, and then the fixing component 6 can fix the arc plate 403. During the rotation of the electric rotating ring 103, the ring plate 402 is driven to rotate. During the rotation of the ring plate 402, the arc plate 403 is driven to rotate. When the assembled charging plug moves to the first conveyor belt 205, the corresponding second connecting hole 406 is connected to the first connecting hole 405. Then, during the process of the mounting plate 106 moving upward and compressing the telescopic tube 206, the airflow in the telescopic tube 206 flows into the mounting cylinder 401 through the first air pipe 207, and then flows into the sleeve 201 through the first connecting hole 405, the second connecting hole 406, and the second air pipe 407 on the mounting cylinder 401. This causes the push plate 204 at the first conveyor belt 205 to move, thereby driving the assembled and normally powered charging plug to move onto the first conveyor belt 205.

[0027] When the charging plug fails to function properly, it cannot receive power, so the arc plate 403 will not move. When the non-powered charging plug moves to the second conveyor belt 506, the second connecting hole 406 corresponding to the non-powered charging plug will connect with the third connecting hole 507. Then, the airflow in the telescopic tube 206 flows to the mounting cylinder 401, and part of the airflow will flow through the corresponding third connecting hole 507, second connecting hole 406, and second air pipe 407 to the sleeve 201 at the second conveyor belt 506. It should be noted that a labyrinth-type sealing groove is provided between the outer wall of the mounting cylinder 401 and the inner wall of the annular plate 402; and the edge of the arc plate 403 is embedded with a Teflon sealing strip, so that it maintains airtight contact with the outer wall of the mounting cylinder 401 when sliding along the vertical groove, ensuring that the pressurized airflow generated by the first connecting hole 405 is accurately delivered into the second connecting hole 406 without leakage. Then, under the action of airflow, the mounting rod 202 at the second conveyor belt 506 drives the push plate 204 to move, and drives the unusable charging plug to move onto the second conveyor belt 506. Therefore, there is no need for the user to spend time to check the assembled charging plug again, which further improves production efficiency.

[0028] like Figure 5 , Figure 7 As shown, the fixing component 6 includes a connecting groove 601 formed at the top of the arc-shaped plate 403, a fixing groove 602 formed on the side wall of the connecting groove 601, a linkage plate 603 uniformly and horizontally slidably mounted on the top wall of the annular plate 402, and the top wall of the linkage plate 603 is inclined, a fourth spring 604 is installed between the linkage plate 603 and the annular plate 402, a connecting rod 605 is fixedly mounted on the bottom wall of the linkage plate 603, a fixing block 606 is fixedly mounted on the bottom end of the connecting rod 605, and an inclined groove 607 is formed on the fixing block 606, and a release rod 608 is fixedly mounted on the bottom wall of the mounting plate 106.

[0029] By adopting the above technical solution, during the upward movement of the arc plate 403, the connecting groove 601 on the arc plate 403 gradually contacts the inclined groove 607 of the fixed block 606 and applies a pushing force to the inclined groove 607. Then, under the action of the pushing force, the fixed block 606 drives the linkage plate 603 to move through the connecting rod 605 and compresses the fourth spring 604. During the upward movement of the arc plate 403, the fixed block 606 gradually enters the fixed groove 602 through the connecting groove 601. After the fixed block 606 enters the fixed groove 602, the fourth spring 604 extends and drives the fixed block 606 to move into the fixed groove 602 through the linkage plate 603 and the connecting rod 605, thereby fixing the arc plate 403. Then, during the rotation of the electric rotating ring 103, the linkage plate 603 is driven to rotate through the ring plate 402. When the corresponding linkage plate 603 rotates through the first conveyor belt 205 to the loading area, as the mounting plate 106 moves downward, the mounting plate 106 drives the release rod 608 to move downward. During the downward movement of the release rod 608, it gradually contacts the inclined surface of the top wall of the linkage plate 603 and applies a pushing force to the inclined surface. Then, under the action of the pushing force, the linkage plate 603 moves horizontally and compresses the fourth spring 604 again. During the movement of the linkage plate 603, the connecting rod 605 drives the fixing block 606 to disengage from the fixing groove 602. After the fixing block 606 disengages from the fixing groove 602, the third spring 404 extends and drives the arc plate 403 to return to its downward reset position. Then, during the upward movement of the mounting plate 106, the release rod 608 returns to its upward reset position, thus preparing for the next operation.

[0030] like Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 10 , Figure 11As shown, a first linkage rod 701 is fixedly installed on the bottom wall of the mounting plate 106. An electric circular slide rail 702 is fixedly installed at the bottom end of the first linkage rod 701. A second electric telescopic rod 703 is slidably installed on the electric circular slide rail 702. A glue applicator 704 is fixedly installed on the output end of the second electric telescopic rod 703. A glue tank 705 is fixedly installed on the top wall of the top plate 104. A material conveying pipe 706 communicating with the glue applicator 704 is inserted into the glue tank 705.

[0031] A second linkage rod 801 is fixedly installed on the bottom wall of the mounting plate 106. A hollow ring 802 is fixedly installed at the bottom end of the second linkage rod 801. Air holes 803 are evenly opened on the hollow ring 802, and the bottom wall of the air hole 803 forms a 60-degree angle with the vertical plane.

[0032] A gas spring 804 is vertically slidably mounted on the top plate 104. A linkage spring 805 is installed between the gas spring 804 and the top plate 104. A ventilation groove 806 is provided on the gas spring 804. A third air pipe 807 communicating with the ventilation groove 806 is inserted into the hollow ring 802.

[0033] By adopting the above technical solution, after the assembled and functional charging plug passes through the second conveyor belt 506, it moves to the bottom of the glue applicator 704. Then, as the mounting plate 106 moves downward, the first linkage rod 701 drives the electric circular track to move downward. When the mounting plate 106 reaches the lowest point, the glue applicator 704 contacts the joint between the upper and lower shells. Then, the electric circular track drives the glue applicator 704 to rotate through the second electric telescopic rod 703. At this time, the sealant in the glue tank 705 is evenly applied to the joint between the upper and lower shells through the feed pipe 706 and the glue applicator 704, thereby automatically sealing the charging plug. The simultaneous operation of multiple stations can effectively improve production efficiency.

[0034] As the charging plug, after the adhesive application is completed, moves to the hollow rotating ring along with the electric rotating ring 103, the mounting plate 106 gradually contacts the air rod 804 and drives the air rod 804 to move upward during the upward movement of the mounting plate 106. At this time, the linkage spring 805 is compressed and has a tendency to return to its original position. After the push plate 204 pushes the charging plug onto the corresponding first conveyor belt 205 and second conveyor belt 506, the air rod 804 drives the air groove 806 to connect with the third air pipe 807. At this time, the first spring 203 in the sleeve 201 at the first conveyor belt 205 extends and drives the mounting rod 202 to return to its original position. The airflow in the corresponding sleeve 201 flows to the mounting cylinder 401 through the second air pipe 407, the second connecting hole 406, and the first connecting hole 405. At the same time, the second conveyor belt 50... The first spring 203 inside the six sleeves 201 extends and drives the corresponding mounting rod 202 to reset. At this time, the airflow in the corresponding sleeve 201 flows into the mounting cylinder 401 through the second air pipe 407, the second connecting hole 406, and the third connecting hole 507. Then, the airflow in the mounting cylinder 401 flows into the telescopic pipe 206 through the first air pipe 207, and then into the third air pipe 807 through the telescopic pipe 206 and the venting groove 806. Then, it flows into the hollow ring 802 through the third air pipe 807. Through the inclined air holes 803, an annular micro-airflow is formed, which is precisely blown at the joint between the upper and lower shells. This is used to blow away plastic particles or dust attracted by electrostatic adsorption caused by mechanical pressing at the joint before applying the adhesive, thereby significantly improving the bonding strength and waterproof yield of the subsequent sealant.

[0035] like Figure 3 , Figure 12 As shown, the clamping assembly includes grooves evenly opened on the electric rotating ring 103. A limiting block 901 is slidably installed in the groove. A second spring 902 is installed between the limiting block 901 and the groove. A spring telescopic rod 903 is symmetrically fixed on the bottom wall of the mounting plate 106, and the output end of the spring telescopic rod 903 is an inclined surface.

[0036] A clamping block 904 is symmetrically slidably mounted on the limiting block 901. A return spring 905 is installed between the clamping block 904 and the limiting block 901, and the sidewall of the two clamping blocks 904 on the adjacent side is an inclined surface.

[0037] By adopting the above technical solution, when the user places the lower shell on the electric rotating ring 103, the user can place the lower shell between the two limiting blocks 901. Then, as the mounting plate 106 moves downward, the mounting plate 106 will drive the spring telescopic rod 903 to move downward. At this time, the inclined surface of the output end of the spring telescopic rod 903 will gradually contact the limiting blocks 901, and drive the two limiting blocks 901 to move closer to each other. As the two limiting blocks 901 move closer to each other, they gradually contact the lower shell, and drive the lower shell to move directly downward from the upper shell. Furthermore, by setting two clamping blocks 904, the clamping blocks 904 will move as the limiting blocks 901 move. During the movement, the lower shell is aligned perpendicular to the sleeve 201. After the lower shell is aligned perpendicular to the sleeve 201, the limit block 901 continues to move the clamping block 904. The inclined surface of the clamping block 904 will move the lower shell parallel to the sleeve 201. After the lower shell is aligned, the limit block 901 continues to move the clamping block 904. The lower shell will move the clamping block 904 and compress the return spring 905. Under the action of the return spring 905, the lower shell can be clamped. Therefore, the user does not need to spend time manually aligning the lower shell or clamping it, which further improves the production efficiency of the charging plug.

[0038] After the charging plug is assembled, as the mounting plate 106 moves the spring telescopic rod 903 upward, the second spring 902 and the return spring 905 extend, respectively driving the corresponding limit block 901 and clamping block 904 back to the initial avoidance position, releasing the clamping constraint of the lower shell, and waiting for the next round of material feeding.

[0039] Instructions for use: First, manually place the lower casing of the charging plug sequentially on the clamping assembly station of the electric rotating ring 103, relying on the cooperation of the limiting block 901 and the clamping block 904 to achieve initial placement and positioning; at the same time, start the conveyor belt 102 to orderly transport the upper casing of the charging plug with terminals to one side of the assembly station, and the electric slide rail 301 drives the clamping plate 304 to move above the conveyor belt 102, and the electric bidirectional threaded rod 303 rotates, driving the two sets of clamping plates 304 to move closer to each other, accurately clamping the upper casing of the charging plug on the conveyor belt 102; after clamping, the electric slide rail 301 resets and moves, moving the upper casing to the position directly above the corresponding lower casing of the electric rotating ring 103 to wait.

[0040] Then, the electric rotating ring 103 intermittently rotates and changes position, completing multi-station cyclic operation, accurately conveying the placed plug lower shell to the position directly below the upper shell; subsequently, the electric push rod 105 under the top plate 104 extends, pushing the mounting plate 106 downward as a whole, simultaneously driving the upper shell to slowly press down, so that the upper shell and lower shell are initially connected and embedded. After the upper and lower shells are initially attached, the electric bidirectional threaded rod 303 reverses, the clamping plate 304 releases the upper shell, and the first electric telescopic rod 305 pushes downward, completely pressing and clamping the upper shell, completing the assembly of the charging plug body; during the same time period, the operator can simultaneously place a new plug lower shell in an empty workstation, realizing multi-station synchronous operation of assembly and material loading.

[0041] Furthermore, as the assembled plug continues to rotate with the electric rotating ring 103 and is transferred to the testing station: the mounting plate 106 moves downward, causing the vertical rod 504 and the power connector 505 to move down synchronously. The power connector 505 is inserted into the finished product charging plug for power-on testing. When the finished product is powered on and passes the test: the power contact 503 is connected, the electromagnet 501 is energized and generates a repulsive force, pushing the magnet block 502 and the arc plate 403 upward. This, together with the fixing component 6, locks the arc plate 403, and the corresponding second connecting hole 406 and the first connecting hole 405 switch the docking path. When the finished product fails to power on: the circuit cannot be connected, the electromagnet 501 does not work, the arc plate 403 remains in its initial position, and the corresponding second connecting hole 406 and the third connecting hole 507 maintain their original docking state.

[0042] Subsequently, qualified finished products are moved to the corresponding workstation on the first conveyor belt 205 by the electric rotating ring 103. During the equipment reset and upward movement, the telescopic tube 206 contracts and squeezes the internal air. The airflow is sent into the corresponding sleeve 201 through the first air pipe 207, the adjusting component 4, and the second air pipe 407. The air pressure pushes the mounting rod 202 and the push plate 204 to move, pushing the qualified finished products to the first conveyor belt 205 to complete the discharge of good products. Defective products are transferred to the workstation on the second conveyor belt 506. The airflow is connected to the third connecting hole 507 and the first connecting hole 405 on the corresponding side. The push plate 204 moves to push the defective finished products to the second conveyor belt 506, realizing the automatic classification and unloading of good and bad products.

[0043] Finally, after the qualified plugs are sorted, they are transferred to the gluing station by the electric rotating ring 103. The mounting plate 106 moves down, driving the gluing machine 704 to move down synchronously. The electric circular slide rail 702 drives the gluing machine 704 to rotate around the plug joint. The sealant in the glue tank 705 is conveyed through the material conveying pipe 706 and evenly applied to the joint between the upper and lower shells to complete the joint sealing gluing operation. After the gluing is completed, the plugs continue to be moved. When the equipment moves up to reset again, the air rod 804 is lifted and the air groove 806 is connected to the third air pipe 807. The first spring 203 in each sleeve 201 returns to its original position. The internal return airflow is introduced into the hollow ring 802 through the air groove 806 and the third air pipe 807 and blown out from the inclined air hole 803. Before the gluing machine 704 operates, the joint is cleaned with pneumatic dust blowing to avoid impurities affecting the gluing sealing quality.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
