Technical Field

[0001] The present invention relates to the technical field of electrical appliance processing, and particularly to an integrated welding and cutting processing device for a charger. Background Art

[0002] In daily life, we often use different chargers to charge our different electrical devices, resulting in a large inventory of chargers. A commonly used charger generally consists of a wire, a housing, and a circuit board disposed within the housing, and multiple electronic components are carried on the circuit board. In the production of chargers, first, multiple electronic components need to be welded and fixed on the circuit board substrate, and then the circuit board is assembled into the housing. Among them, the processing of the circuit board is of utmost importance. For the circuit board processing steps, first, the blank board is printed to form multiple circuit substrates on the blank board, then the substrates are cut from the blank board, and the electronic components are placed at the corresponding welding points on the substrates, and finally, the circuit board processing is completed by welding.

[0003] However, in actual existing production, the welding of circuit boards is mostly carried out manually, resulting in a low qualified rate of products and high costs. Even if some processes use automatic cutting equipment and automatic welding equipment, the two devices mostly exist independently and cannot achieve process coordination. Therefore, in actual application, not only do multiple independent devices need to be debugged separately, but also manual cooperation is required for material transfer, which greatly reduces production efficiency and cannot achieve complete automation of production. Summary of the Invention

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to the attached Figure 1 - attached Figure 10, an embodiment of the present invention provides an integrated welding and cutting processing device for a charger, including a cutting table 1, the bottom wall of the cutting table 1 is fixedly connected to the top of a conveyor 2. The cutting table 1 is used to clamp and fix the printed blank board to be cut. Above the cutting table 1, there is a cutting device 3, which is used to cut the printed blank board. A guiding unit is arranged on the conveying path of the conveyor 2. When the substrate is cut from the printed blank board by the cutting device 3, the substrate falls onto the conveyor belt of the conveyor 2 and realizes the automatic adjustment of the arrangement position and the discharging position under the continuous guiding action of the guiding unit. Below the discharging end of the conveyor 2, there is a conveyor 4, and above it, there is a material transfer device. On the conveying path of the conveyor 4, there are a plurality of substrate clamping units 5, and the substrate clamping units 5 move synchronously with the conveyor 4. Through the material transfer device, the substrate at the discharging port of the conveyor 2 enters the lower substrate clamping unit 5 for clamping and fixing. On the conveying path of the conveyor 4, there are two start-stop trigger points. On both sides of the start-stop trigger point close to the conveyor 2, there are respectively an automatic component insertion device and an automatic welding device 1. On both sides of the other start-stop trigger point, there are respectively an automatic welding device 2 and a discharging device 6. When the conveyor 4 drives the clamping unit loaded with the substrate to move to the start-stop trigger point close to the conveyor 2, the conveyor 4 stops running. At the same time, the automatic component insertion device places a plurality of electronic components on the corresponding welding points of the substrate, and the automatic welding device 1 welds the electronic components to the substrate to complete the front-side welding. When the conveyor 4 drives the clamping unit loaded with the substrate that has completed the front-side welding to move to the other start-stop trigger point, the conveyor 4 stops running again. At the same time, the substrate automatically flips, and the automatic welding device 2 welds the corresponding points on the back side of the substrate. Then, the discharging device 6 removes the substrate that has completed the back-side welding.

[0018] Through the cooperation of the conveyor 2, the conveyor 4 and the material transfer device, the connection between the cutting device 3 and the automatic welding device is realized, the problem of manual cooperation for material transfer is solved, the production efficiency is greatly improved. At the same time, with the cooperation of the substrate clamping unit 5 and the start-stop trigger points, the workpieces during transfer can accurately reach the welding positions, and finally the processes of automatic cutting and welding are realized, thus realizing automated production.

[0019] The cutting table 1 includes a base 101. The bottom wall of the base 101 is fixedly connected to the tops of the two side walls of the first conveyor 2. The base 101 adopts a hollow frame structure, and an embedding groove 102 is formed in the upper part of the base 101. A blanking plate 103 is slidably connected to the side of the embedding groove 102 away from the input end of the first conveyor 2. A first spring 104 is arranged between the blanking plate 103 and the side wall of the embedding groove 102. A clamping plate 105 is arranged on the other side of the embedding groove 102. The two ends of the clamping plate 105 are rotatably connected to the side wall of the base 101, and the upper part of the clamping plate 105 is snap-fitted with the upper wall of the base 101. Before feeding, pull and turn down the clamping plate 105 to separate its snap-fitting part from the base 101, then insert the printed blank plate into the embedding groove 102, and turn up the clamping plate 105 to make it snap-fitted with the base 101. At this time, the clamping plate 105 and the blanking plate 103 respectively limit and fix the printed blank plate, and the first spring 104 is in a compressed state. After cutting, pull and turn down the clamping plate 105 to separate its snap-fitting part from the base 101. Part of the plate body of the printed blank plate is pushed out by the blanking plate 103 under the elastic force of the first spring 104, and then the printed blank plate is pulled out of the embedding groove 102.

[0020] The cutting table 1 is mainly used to carry the printed blank plate to be cut. During the actual processing, the printed blank plate is inserted into the embedding groove 102, and then the clamping plate 105 is turned up to make it snap-fitted with the base 101, so as to complete the limit and fixation of the printed blank plate, facilitating the subsequent cutting steps. After complete cutting, pull and turn down the clamping plate 105. The remaining part of the printed blank plate is pushed out by the blanking plate 103 under the elastic force of the first spring 104, facilitating the extraction and replacement of the remaining part of the printed blank plate from the embedding groove 102.

[0021] The guiding unit includes a guiding plate 7. The guiding plate 7 is composed of a folding plate and a straight plate, which are respectively fixedly connected to the two side walls of the first conveyor 2. A gradually converging channel is formed between the two. The opposite surfaces of the folding plate and the straight plate are smoothed. At the same time, both of them extend outside the discharge end of the first conveyor 2 and are connected by a baffle 701 to form a blanking port 702. Two first lower stoppers 703 are arranged at the bottom of the blanking port 702. The upper parts of the two first lower stoppers 703 are both inclined surfaces, and the two first lower stoppers 703 are respectively embedded and slidably connected in the folding plate and the straight plate. At the same time, the two first lower stoppers 703 are respectively connected to the folding plate and the straight plate by second springs 704.

[0022] The substrate is cut from the printed blank plate by the cutting device 3. Under the action of gravity, the substrate falls into the first conveyor 2. Along with the movement of the conveyor belt of the first conveyor 2, during the movement, under the action of the guiding plate 7, the angle and position of the substrate are gradually adjusted to adapt to the gradually converging channel, and finally the substrate moves to the blanking port 702 and is blocked by the baffle 701.

[0023] The material transfer device includes a bracket 8, which is arranged on the side of the blanking port 702. A power push rod 9 is fixedly connected to the top of the bracket 8, and a first electric suction cup 10 is fixedly connected to the output end of the power push rod 9. The position of the first electric suction cup 10 corresponds to the blank position on the substrate.

[0024] The power push rod 9 pushes the first electric suction cup 10 downward, so that the first electric suction cup 10 is attached to and contacts the blank position on the substrate, realizing the vacuum adsorption and fixation of the substrate. Then, the power push rod 9 continues to push the first electric suction cup 10 downward, so that the substrate presses against the first lower stop block 703. Under the action of the inclined surface, the vertical force received by the first lower stop block 703 is converted into a horizontal force, thereby overcoming the elastic force of the second spring 704, compressing the second spring 704 and retracting it into the folding plate and the straight plate. At this time, the blocking of the first lower stop block 703 on the substrate is eliminated, and the substrate is pushed into the substrate clamping unit 5. The adsorption of the first electric suction cup 10 is cancelled, and the substrate is clamped and fixed by the substrate clamping unit 5. Of course, during this process, the first conveyor 2 is in a stopped state.

[0025] The substrate clamping unit 5 includes a bottom plate 501. The bottom wall of the bottom plate 501 is fixedly connected to the moving end of the second conveyor 4 through a support frame 502. One side of the bottom plate 501 is rotatably connected to a top plate 503. The top plate 503 and the bottom plate 501 are magnetically attracted to each other, forming a flipping structure. When the top plate 503 is turned inward, the top plate 503 covers the bottom plate 501 and is parallel to the bottom plate 501. When the top plate 503 is turned outward, the top plate 503 and the bottom plate 501 form an angle of 180°. The top plate 503 is hollow and open. An upper stop block 504 is embedded and slidably connected to the inner side of the upper part of the opening. A third spring 505 is also connected between the side wall of the upper stop block 504 and the top plate 503. The upper part of the upper stop block 504 is provided with an inclined surface. A lower stop block 506 is embedded and slidably connected to the inner side of the lower part of the opening. The lower stop block 506 and the top plate 503 are connected by a fourth spring 507. At the same time, a top block 508 is embedded and slidably connected between the lower stop block 506 and the top plate 503. A yielding inclined surface is provided on the side of the top block 508 facing the lower stop block 506. The top block 508 and the top plate 503 are fixedly connected by a fifth spring 509. The elastic force of the fifth spring 509 is greater than the elastic force of the fourth spring 507. Before the unloading device 6 operates, the yielding inclined surface of the top block 508 penetrates and is located outside the top plate 503. Symmetrically arranged two limiting grooves 510 are provided at both end faces of the rotating shaft of the top plate 503, and the limiting grooves 510 at both end faces are connected by a wire.

[0026] In the initial state, the top plate 503 covers the bottom plate 501, and both are parallel to the horizontal plane. The two are fixed by magnetic attraction. The substrate is pushed by the material transfer device to the hollow opening of the top plate 503. After continuous extrusion, the upper stopper 504 is pushed to retract against the elastic force of the third spring 505, so that the substrate is embedded between the upper stopper 504 and the second lower stopper 506 and is limited and fixed by the two. This facilitates subsequent arrangement and welding operations of electronic components.

[0027] A motor 11 is provided at the start-stop trigger point. The outer wall of the motor 11 is fixedly connected to the side wall of the second conveyor 4. The output end of the motor 11 is fixedly connected to a first plug board 12. A rotating column 13 is rotatably connected to the side wall of the second conveyor 4 on the side opposite to the motor 11. A second plug board 14 corresponding to the first plug board 12 is fixedly connected to the end face of the rotating column 13. The first plug board 12 and the second plug board 14 are both matched with the limiting groove 510. The first plug board 12 and the second plug board 14 are respectively connected to the circuit of the start-stop trigger switch. When the first plug board 12 and the second plug board 14 are both inserted into the corresponding limiting groove 510, the first plug board 12 and the second plug board 14 are connected through a wire, and at this time, the circuit of the start-stop trigger switch is in a conducting state, and the start-stop trigger switch is triggered.

[0028] It should be noted that the cutting device 3, the automatic component inserting device, the first automatic welding device and the second automatic welding device all adopt existing devices. The operation of the entire integrated processing device is mainly controlled by the control system in an overall manner. The function of the start-stop trigger point is to trigger the switch of specific control steps. For example, when the first start-stop trigger point is triggered, the first conveyor 2 and the second conveyor 4 stop running, and the automatic component inserting device and the first automatic welding device start to work. After welding is completed, the control system controls the motor 11 to run, and finally controls the first conveyor 2 and the second conveyor 4 to continue running.

[0029] The unloading device 6 includes a biaxial displacement frame 601. The center of the output end of the biaxial displacement frame 601 is fixedly connected to an electric suction cup two 602. A slide bar 603 is inserted and slidably connected to the edge. The bottom end of the slide bar 603 is fixedly connected to a pressing plate 604. An opening for the electric suction cup two 602 to pass through is opened in the center of the pressing plate 604. A sixth spring 605 is also connected between the pressing plate 604 and the output end of the biaxial displacement frame 601. The sixth spring 605 is sleeved on the outer wall of the slide bar 603. The biaxial displacement frame 601 drives the electric suction cup two 602 to move in the vertical direction and the horizontal direction perpendicular to the conveying path of the second conveyor 4. When the electric suction cup two 602 moves to directly above the substrate, the position of the electric suction cup two 602 corresponds to the blank position on the back of the substrate.

[0030] When the substrate clamping unit 5 loaded with the substrate moves to the first start-stop trigger point under the drive of the conveyor 2 4, at this time, the symmetrically arranged plug plate 1 12 and plug plate 2 14 are respectively embedded in the limit grooves 510 at both ends of the rotating shaft of the top plate 503, so that the circuit of the start-stop trigger switch is connected, the start-stop trigger switch is triggered, and the conveyor 2 4 stops moving. At the same time, the automatic component insertion equipment places multiple electronic components on the corresponding welding points of the substrate, and then the automatic welding equipment 1 welds the electronic components to the substrate to complete the front welding. Then, according to the preset control program, the control system controls the operation of the motor 11, that is, the motor 11 rotates, and drives the top plate 503 with the limit slot 510 to rotate through the plug plate 1 12, so that the top plate 503 is turned outward by 180°. At this time, the plug plate 1 12 and the plug plate 2 14 are respectively in a separable state from the limit slot 510, that is, the control system controls the conveyor 2 4 to operate, and the plug plate 1 12 and the plug plate 2 14 are respectively separated from the limit slot 510; when the substrate with the front welding completed moves to the second start-stop trigger point, at this time, the plug plate 1 12 and the plug plate 2 14 are again embedded in the limit slot 510, and the start-stop trigger switch is triggered again, then the conveyor 2 4 stops moving, and at the same time, the automatic welding equipment 2 welds the corresponding points on the back of the substrate. After the back welding is completed, the unloading device 6 removes the substrate. At the same time, the motor 11 here rotates in the opposite direction, so that the top plate 503 is turned inward and fixed to the bottom plate 501 by magnetic attraction. The first plugging plate 12 and the second plugging plate 14 are respectively in a detachable state from the limiting groove 510 .

[0031] The specific steps of the unloading device 6 taking out the substrate are: The electric suction cup 2 602 is driven to move to the top of the substrate by the dual-axis displacement frame 601, and then the electric suction cup 2 602 is driven to descend. During the descent, the pressure plate 604 first contacts the top block 508, and with the continuous compression of the spring six 605, the top block 508 is retracted toward the top plate 503. Then, under the action of the spring four 507, the lower block 2 506 is pulled to retract along the retreat slope, thereby releasing the obstruction of the lower block 2 506 to the substrate. At the same time, the electric suction cup 2 602 contacts the empty position on the back of the substrate and is adsorbed and fixed. At this time, the dual-axis displacement frame 601 drives the electric suction cup 2 602 to move upward, and the pressure plate 604 still presses the top block 508 under the action of the spring six 605, and the substrate is moved out by the electric suction cup 2 602.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
