When the metal support block rotates to the insulating end position, the electric energy and the magnetic force disappear, causing the material to lose its adsorption force and fall into the storage box, thereby realizing a precise welding function of the chip aluminum electrolytic capacitor welding device.

[0004] The specification of Chinese patent CN108054030B discloses a capacitor positioning welding device, including a base and a support block slidably connected to the base. A clamping portion is fixed to the base, and a plurality of support columns are provided on one side of the clamping portion. The clamping portion includes a clamping portion body and a clamping plate. The present invention has a simple structure and can be used for positioning welding of capacitors.

[0005] A laser output head is used to laser weld the connection points between the lead wire and the welding pad. However, if the welding pad is offset during the loading process, the positioning of the welding point and the laser output head will be inaccurate, affecting the welding efficiency. Therefore, it is necessary to design a high-precision positioning device for aluminum electrolytic capacitor welding inspection to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that once the loading deviation occurs during the loading process of the welding plate, the positioning state of the welding point and the laser output head will be inaccurate, which will affect the welding efficiency.

[0007] In order to solve the above problems, the utility model provides a high-precision positioning device for welding inspection of aluminum electrolytic capacitors, including a rotating disc, a locking base is provided at the upper end of the rotating disc, the locking base is fixedly connected to a matching front seat at one end close to the welding workbench, the upper end of the matching front seat is fixedly connected to a locking bottom plate, the upper end of the locking base is locked with a capacitor body, the output end of the capacitor body is connected to a lead bar, the lead bar is connected to the welding disc, the middle part of the upper end of the locking bottom plate is fixedly connected to a locking positioning area, a plurality of vertical slots are opened at the upper end of the locking bottom plate, the lower inner wall of the vertical slots is fixedly connected to a spring, the upper end of the spring is fixedly connected to a hollow column, and the lower inner wall of the vertical slot located on the upper side of the locking positioning area is fixedly connected to a contact sensor.

[0008] In the above-mentioned high-precision positioning device for aluminum electrolytic capacitor welding inspection, the multiple hollow columns above the positioning area in this solution are uniformly pressed down by the welding disk, and the bottoms of the pressed hollow columns can contact each other with the corresponding contact sensors, avoiding the risk of defective products caused by misalignment of welding points, which is beneficial to ensuring the accuracy of the welding process.

[0009] As a further improvement of the present application, the locking base is located below the welding workbench, and the welding disk is located on the upper side of the locking base plate.

[0010] As a further improvement of the present application, a welding workbench is installed on the left side of the rotating disc, and a pair of laser output heads are installed at the lower end of the welding workbench.

[0011] As another improvement of the present application, a plurality of contact sensors cooperate with corresponding hollow columns, and a welding plate cooperates with a plurality of hollow columns above the positioning area.

[0012] As another improved supplement of the present application, a red prompt coating is fixedly connected to the upper end of the hollow column, and the red prompt coating is in contact with the welding disk.

[0013] As another improved supplement of the present application, an inner storage tank is provided at the inner end of the locking base plate, and the inner storage tank is interconnected with the plurality of vertical slots.

[0014] As another improved supplement of the present application, a plurality of air suction hood openings are installed at the inner end of the inner storage tank, and the plurality of air suction hood openings are all externally connected to a pump.

[0015] In summary, in this solution, after the welding disk is placed in the correct position by the robot, the position of the welding disk corresponds to the positioning area. At this time, the multiple hollow columns above the positioning area are uniformly pressed down by the welding disk, and the bottom of the pressed hollow columns can contact the corresponding contact sensors. After the contact sensors all receive the contact signals, the external control terminal determines that the processing position of the welding disk is accurate. After the welding disk is placed in an inaccurate position by the robot, the multiple contact sensors on the positioning area do not all receive the contact signals. The external control terminal determines that the processing position of the welding disk is inaccurate, and can remind the staff to come and deal with it in time to avoid the risk of defective products caused by misalignment of welding points, which is beneficial to ensure the accuracy of the welding process.

[0025] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0026] The first implementation method:

[0027] Figure 1-5 A high-precision positioning device for welding review of aluminum electrolytic capacitors is shown, which includes a rotating disc 1. A locking base 4 is provided at the upper end of the rotating disc 1. The locking base 4 is fixedly connected to a matching front seat 5 at one end close to the welding workbench 2. The upper end of the matching front seat 5 is fixedly connected to a locking base plate 6. The upper end of the locking base 4 is locked with a capacitor body 9. The output end of the capacitor body 9 is connected to a lead bar 8, and the lead bar 8 is connected to the welding disc 7.

A plurality of vertical slots 10 are opened at the upper end of the locking base plate 6. The lower inner wall of the vertical slot 10 is fixedly connected to a spring 11. The upper end of the spring 11 is fixedly connected to a hollow column 12. The lower inner wall of the vertical slot 10 located on the upper side of the locking positioning area 13 is fixedly connected to a contact sensor 14.

[0028] Figure 1-5 It is shown that the locking base 4 is located below the welding workbench 2, the welding disk 7 is located on the upper side of the locking base plate 6, the welding workbench 2 is installed on the left side of the rotating disk 1, and a pair of laser output heads 3 are installed at the lower end of the welding workbench 2. Multiple contact sensors 14 cooperate with corresponding hollow columns 12, and the welding disk 7 cooperates with multiple hollow columns 12 above the locking positioning area 13.

[0029] Figure 1-5The embodiment of the present invention is that a plurality of snap-fitting bases 4 can be arranged in an annular shape on the self-rotating disc 1, and an external loading robot is used to place the capacitor body 9 with the lead wire 8 and the welding disc 7 above the snap-fitting base 4 and the matching front seat 5 respectively. Under the rotation of the self-rotating disc 1, the snap-fitting base 4 passes through the position of the welding workbench 2 in sequence, and the connection point of the lead wire 8 and the welding disc 7 is laser welded by the laser output head 3. The welded finished product is taken out again by the external unloading robot, and the empty snap-fitting base 4 continues to rotate on the self-rotating disc 1. During the loading process of the welding disc 7, if the loading deviation occurs, the positioning state of its welding point and the laser output head 3 will be inaccurate. Therefore, the present invention provides a snap-fitting base 6 on the matching front seat 5, and a plurality of vertical slots 10 are provided on the snap-fitting base 6. The hollow columns 12 in the plurality of vertical slots 10 can be flexibly moved up and down by springs 11. After the welding disc 7 is placed in the correct position by the robot, the position of the welding disc 7 is When the welding plate 7 is placed in the correct position, the multiple contact sensors 14 on the positioning area 13 do not all receive the contact signals, and the external control terminal determines that the processing position of the welding plate 7 is incorrect, which can remind the staff to come and deal with it in time, avoiding the risk of defective products caused by misalignment of welding points, which is beneficial to ensuring the accuracy of the welding process. At the same time, when the welding plate 7 is placed in the correct position, the welding plate 7 moves with the engaging base 4, and the hollow columns 12 on its outside can also play a limiting role, avoiding the centrifugal force on the welding plate 7 during rotation. The offset further ensures the positioning accuracy of the welding plate 7 during welding.

[0030] Second implementation method:

At the same time, a number of red prompt coatings 15 are also provided on the upper side of the hollow column 12 above the clamping positioning area 13. The red prompt coating 15 can assist the staff who come to check to promptly identify the correct discharge position. At the same time, an inner storage tank 16 can also be provided in the clamping base plate 6. The suction hood port 17 in the inner storage tank 16 can use an external pump to use the connected inner storage tank 16 and the vertical slot 10 to align the laser output head 3 with the bad gas in the welding process above the clamping base plate 6 for auxiliary absorption, thereby further ensuring the qualified rate of the air quality in the workshop.
