[0002] With the development of electronic industry technology, the market demand for circuit boards is increasing. In the existing technical field, especially in the processing of new energy vehicle headlight circuit boards, various electronic components are usually welded and assembled on the circuit boards. In the past, most of them were welded manually, which was inefficient and had unstable welding quality. Now, more and more processes use automatic welding, which can automatically weld the electronic components on the circuit board one by one according to the set program through automatic welding robots, thereby improving production efficiency and processing quality.

[0003] When using an automatic welding robot to automatically weld components on a circuit board, it is necessary to accurately position the circuit board to be welded before welding. That is, when the circuit board is fed to the welding station, the printed circuit board after feeding must be accurately positioned. This will make it easier for the welding robot to accurately weld each small electronic component to the corresponding position of the circuit board. If the position of the printed circuit board after feeding deviates, the proportion of wrong welding, false welding and missed welding by the automatic welding robot will increase significantly.

[0018] See also Figure 1-12 The present invention provides a technical solution: an automatic production line for a new energy vehicle headlight circuit board and a working method thereof, comprising a loading belt 7, a feeding belt 701, a welding table 1, a positioning component and a lifting component, The feeding belt 7 is used to continuously transport the circuit board body 6 to the welding station 1; The positioning assembly includes four groups of positioning plates 101. A plurality of square openings 102 are provided at the upper end of the welding table 1. The positioning plates 101 slide in the square openings 102. A guide telescopic rod 103 is provided in the square openings 102. The guide telescopic rod 103 is connected to the positioning plates 101. The four groups of positioning plates 101 move relative to each other to position the circuit board body 6. A limiting rod 104 is provided at the lower end of the positioning plate 101, and four sets of driving disks 105 are rotatably connected to the lower end of the welding table 1. A plurality of limiting grooves 106 are provided in an annular shape on the upper side of the driving disk 105, and the limiting rod 104 extends into the limiting grooves 106; The feeding belt 701 is used to receive and transport the soldered circuit board body 6; The horizontal heights of the loading belt 7 and the feeding belt 701 are higher than the upper end surface of the welding table 1. The lifting assembly includes a pair of lifting blocks 3. The upper ends of the lifting blocks 3 are set as round chamfers. The lifting blocks 3 are used to lift the soldered circuit board body 6 until it is equal to the horizontal height of the feeding belt 701.

[0019] First, the circuit board body 6 is transported to the welding table 1 through the feeding belt 7; the circuit board body 6 falls to the upper end surface of the welding table 1, and then the four sets of driving disks 105 rotate synchronously, and the limiting rod 104 is limited by the limiting groove 106, so that the limiting rod 104 moves with the rotation of the driving disk 105, and under the guidance of the guiding telescopic rod 103 and the square opening 102, the positioning plate 101 moves linearly until the circuit board body 6 is centered, so as to automatically find the welding processing position; then the electronic components are automatically placed on the positioned circuit board body 6 by the welding robot and welding is performed until the welding work is completed. The welding accuracy and welding quality of the circuit board body 6 are greatly improved; then, the pair of lifting blocks 3 are raised to lift the welded circuit board body 6 and make it flush with the height of the feeding belt 701, and then the subsequent new circuit board body 6 is transported to the welding table 1 through the feeding belt 7, so that the new circuit board body 6 pushes the welded circuit board body 6, and the circuit board body 6 passes through the upper end of the positioning plate 101 on one side and enters the feeding belt 701; the feeding belt 701 receives the circuit board body 6 and transports it to the next process, and this is repeated to complete the function of automatically positioning and welding the circuit board body 6, thereby improving the work efficiency; It should be noted that welding robots and other equipment are all existing technologies in this field, so they will not be described in detail.

[0020] The lower end of the driving disk 105 is fixedly connected with a gear 107, the lower side of the welding table 1 is provided with a support table 8, the inner side of the support table 8 is provided with a motor component 801, the upper side of the motor component 801 drives a gear 2 108, and the gear 2 108 is meshed and connected with the gear 1 107.

[0021] Preferably, the motor component 801 is used to drive the gear 2 108 to rotate, and the gear 2 108 is meshed with the four sets of gears 1 107 at the same time, thereby driving the gear 107 to rotate synchronously, and the gear 107 can drive the driving disk 105 to rotate synchronously, thereby driving the positioning plate 101 to move relatively synchronously, clamped on the four sides of the circuit board body 6 to be welded, and find the welding position. In other words, the displacement drive of the positioning plate 101 in four directions can be realized by only a single driving component motor component 801, with good synchronization, and further saving costs compared to the prior art of positioning by driving several cylinders or hydraulic cylinders.

[0022] A circular groove is formed at the lower end of the positioning plate 101 , and the circular groove is slidably matched with the limiting rod 104 . A spring retractable rod 109 is provided between the circular groove and the limiting rod 104 .

[0023] Preferably, through the above embodiment, the four groups of positioning plates 101 are displaced synchronously, so that only the square circuit board body 6 can be positioned and aligned. However, in order to further improve the versatility of the present application, so that it is also applicable to welding processing of circuit board bodies 6 of various rectangular sizes, the limit rod 104 is set to be retractable. Specifically, when the motor component 801 drives the four groups of driving disks 105 to rotate synchronously, the limit rod 104 extends out of the circular groove and enters the limit groove 106. At this time, when the driving disk 105 rotates, the limit rod 104 is limited by the limit groove 106, thereby driving the limit rod 104 to drive the positioning plate 101 to move until the positioning plate 101 contacts the side of the circuit board body 6, and the positioning work is completed. However, when positioning the rectangular circuit board body 6, the four groups of positioning plates 101 are displaced synchronously, so that one pair of positioning plates 101 first contacts the two short sides of the circuit board body 6 and clamps and positions them (such as Figure 1 As shown), at this time, the limiting rod 104 on the lower side of the pair of positioning plates 101 is retracted from the limiting groove 106 into the circular groove, so that the driving disk 105 can no longer drive the limiting rod 104 to move, thereby keeping a pair of short-side positioning plates 101 stationary, limiting the short-side direction of the circuit board body 6, and then the four groups of driving disks 105 continue to rotate, so that the positioning plates 101 in the long-side direction continue to move until they also contact and position with the circuit board body 6, thereby realizing the positioning and alignment of the rectangular circuit board body 6, thereby realizing the positioning and alignment of the square or rectangular circuit board body 6, and having strong versatility.

[0024] A T-slot is provided on the inner side of the positioning plate 101, and a plurality of spring telescopic rods 110 are provided at one end of the T-slot. A push plate 111 is provided at one end of the spring telescopic rod 110. A concave block 112 is fixedly connected to the lower end of the push plate 111. The concave block 112 and the push plate 111 are adapted to the T-slot. A square card 113 is fixedly connected to the lower end of the concave block 112. A circular hole is provided on the inner side of the square card 113, and the diameter of the circular hole is equal to that of the limiting rod 104. A pair of card strips 115 are provided on the inner side of the square card 113. Card slots are provided on both sides of the limiting rod 104. The card strips 115 are stuck in the card slots and slidably cooperate with them. The square card 113 limits the limiting rod 104 to extend to the lower side of the circular slot. When the push plate 111 is in contact with the T-slot, the circular hole coincides with the axis of the limiting rod 104.

[0025] Preferably, a clamping strip 115 is provided to match the clamping slot. In the initial state, the clamping strip 115 is clamped into the clamping slot, thereby limiting the limiting rod 104 so that it remains extended into the limiting slot 106. When it is necessary to drive the limit rod 104 back into the circular groove, a push plate 111 is provided. Specifically, when the positioning plate 101 moves to position the circuit board body 6, the push plate 111 first contacts the circuit board body 6, the positioning plate 101 continues to move while the push plate 111 remains stationary, so that the push plate 111 is retracted into the T-slot. At the same time, the push plate 111, the concave block 112 and the square card 113 remain stationary, so that when the positioning plate 101 moves, the limit rod 104 is driven to move relative to the square card 113 until the limit The axis of the rod 104 coincides with the circular hole (at this time, the push plate 111 fits with the T-slot to complete the positioning of the circuit board body 6), that is, the clamping strip 115 and the clamping slot are separated from each other, and the limiting rod 104 loses its restriction and is retracted upward under the action of the spring contraction rod 109, thereby retracting into the circular groove. In other words, the limiting rod 104 automatically retracts into the circular groove when the positioning plate 101 completes the positioning of the circuit board body 6. No additional drive component control is required, and it can be achieved by moving the positioning plate 101, which has a high degree of automation and saves costs.

[0026] The square card 113 penetrates the positioning plate 101 and slides with it. A trapezoidal wedge 114 is fixedly connected to the lower side of one end of the square card 113. A triangular groove is opened on one side of the limiting rod 104, and the trapezoidal wedge 114 is adapted to the triangular groove. A plurality of spring telescopic rods 2 are arranged between the card strip 115 and the frame card 113 .

[0027] Preferably, when the welding work is completed, the positioning plate 101 remains stationary, and the lifting block 3 is moved upward to lift the circuit board body 6 upward until it leaves the positioning range of the positioning plate 101, and the push plate 111 can pop out of the T-slot under the resetting action of the spring telescopic rod 110, and at the same time drive the square frame card 113 to move and reset. However, at this time, the limiting rod 104 is retracted into the circular groove, so that the card strip 115 cannot be inserted into the card slot, but directly expands outward along the two sides of the limiting rod 104, and the spring telescopic rod 1 is compressed (the elastic force of the spring telescopic rod 110 is greater than that of the spring telescopic rod 2). When the locking cam 114 is engaged, the locking cam 115 is engaged with the locking cam 116, and the locking cam 117 is engaged with the locking cam 118. When the locking cam 118 is engaged, the locking cam 118 is engaged with the locking cam 119. When the locking cam 119 is engaged, the locking cam 119 is engaged with the locking cam 117.

[0028] A transverse hole is provided through the middle side of the positioning plate 101, and a convex block 2 is slidably fitted in the transverse hole. The upper and lower ends of the convex block 2 are fixedly connected with baffles, and a spring telescopic rod 201 is provided at one end of the baffle. A plurality of adapting grooves are provided inside the positioning plate 101, and a plurality of locking grooves 203 are provided on the inner side of the square opening 102, and the locking grooves 203 are adapted to the convex block 2; One end of the convex block 2 is set to be chamfered, and one end of the convex block 2 is slidably matched with a trapezoidal block 202. The upper end of the trapezoidal block 202 is provided with a spring telescopic rod 204, and the lower end of the trapezoidal block 202 is in contact with the limit rod 104.

[0029] Preferably, in order to further improve the stability of the positioning plate 101 during positioning, a convex block 2 is provided to match the locking groove 203. When the positioning plate 101 is positioned, the convex block 2 extends out of the horizontal hole and is inserted into the locking groove 203, thereby fixing the current position of the positioning plate 101 and achieving stable positioning of the circuit board body 6. Specifically, when the positioning plate 101 moves and finds the position facing the circuit board body 6, the limiting rod 104 is retracted into the circular groove, thereby pushing the trapezoidal block 202 to rise (the elastic force of the spring retracting rod 109 is greater than the spring telescopic rod four 204 and the spring telescopic rod three 201), the inclined surface of the trapezoidal block 202 is adapted to the inclined surface of the convex card block 2, and the convex card block 2 is pushed to move along the inclined surface, and the convex card block 2 moves along the horizontal hole, thereby being stuck in the locking groove 203, and the automatic fixing of the positioning plate 101 can be completed, and the degree of automation is high; When resetting is required, the limit rod 104 moves downward, and under the resetting action of the spring telescopic rod 3 201, the convex block 2 is reset to release the locked state with the locking groove 203.

[0030] A connecting plate 301 is fixedly connected between a pair of ejecting blocks 3, a ejector rod 302 is fixedly connected to the lower end of the connecting plate 301, a disc 303 is fixedly connected to the lower end of the ejector rod 302, a convex block 308 is arranged at the eccentric position of the lower end of the disc 303, an I-shaped groove is arranged on the upper side of the welding platform 1, a guiding telescopic column is arranged between the ejecting block 3 and the I-shaped groove, a circular groove is arranged on the lower side of the welding platform 1, and the circular groove is adapted to the disc 303; A fixed plate 304 is disposed at the upper end of the gear 2 108, and a second protrusion 305 is fixedly connected to the eccentric portion of the upper end of the fixed plate 304. Both ends of the second protrusion 305 are provided with inclined surfaces, and the second protrusion 305 is adapted to the first protrusion 308; The upper end of gear 2 108 is fixedly connected with a circular block 306, and a plurality of receiving grooves are provided on the outer side of the circular block 306. A spring telescopic rod 5 is provided in the receiving groove, and an arc-shaped tooth 307 is provided at one end of the spring telescopic rod 5. A plurality of arc-shaped grooves are provided on the inner side of the fixed plate 304, and the arc-shaped grooves are adapted to the arc-shaped tooth 307.

[0031] Preferably, a guiding telescopic column is provided to guide the lifting and lowering of the lifting block 3, so as to ensure that the lifting block 3, the disc 1 303 and the protrusion 1 308 can only move up and down. When the lifting block 3 needs to be driven to lift the circuit board body 6, the fixed disc 304 is driven to rotate by the gear 2 108, and the fixed disc 304 drives the protrusion 2 305 to move in a circular manner. When the protrusion 2 305 contacts the protrusion 1 308, since the protrusion 1 308 can only move up and down, the protrusion 1 308 is pushed to move upward along the inclined surface of the protrusion 2 305, so as to drive the lifting block 3 to push the circuit board body 6 to move upward for unloading. Specifically, an arc-shaped tooth 307 is provided to match the arc-shaped groove, and the fixed plate 304 is rotatably connected to the gear 2 108. When the motor 801 drives the gear 2 108 to rotate forward (such as Fig.12 As shown in the figure, the second gear 108 drives the circular block 306 and the plurality of arc-shaped teeth 307 to rotate, and the arc-shaped surface of the arc-shaped teeth 307 contacts the arc-shaped slot, and the force is generated on the arc-shaped surface, so that the arc-shaped teeth 307 are retracted into the receiving slot along the arc-shaped surface to avoid, so that the second gear 108 rotates relative to the fixed disk 304, and does not drive the second protrusion 305 to lift the first protrusion 308. At the same time, the second gear 108 drives the plurality of driving disks 105 to rotate, so that the four groups of positioning plates 101 complete the positioning of the circuit board body 6. Then, when the welding work is completed, the second gear 108 is reversed. While driving several driving disks 105 to rotate idly, the circular block 306 is also driven to rotate. At this time, the arc-shaped tooth 307 rotates against the arc-shaped groove, and the two are locked with each other, thereby driving the fixed disk 304 to rotate synchronously, so that the protrusion 2 305 can lift the protrusion 1 308, so that the circuit board body 6 rises for unloading. In other words, the fixed disk 304 can only be driven to rotate in one direction through the gear 2 108, so that the single motor component 801 can first drive the positioning plate 101 to move to complete the positioning when it rotates forward, and then drives the lifting block 3 to unload when it is reversed. The two do not interfere with each other, have a high degree of automation and save costs.

[0032] A roller 9 is provided at the upper end of the positioning plate 101 adjacent to the loading belt 7 and the feeding belt 701 respectively, a fixed frame 901 is provided on the outer side of the welding table 1, and rollers 9 are similarly provided at both ends of the fixed frame 901.

[0033] Preferably, in order to further reduce the friction on the circuit board body 6 during loading and unloading, a roller 9 is provided. Specifically, when the loading belt 7 transports the circuit board body 6, it first passes through the upper end of the fixed frame 901, and the roller 9 rolls for transmission, and then passes through the roller 9 on the positioning plate 101, and finally falls onto the welding table 1. When unloading, the circuit board body 6 similarly passes through the roller 9 and enters the feeding belt 701 to ensure the surface quality of the surface of the circuit board body 6.
