The present invention is described in detail below in conjunction with the drawings.
[0021] This embodiment provides a transformer paper packaging detection device, such as Figure 1, including a frame 1, on which a feeding mechanism 2, a paper wrapping mechanism 4, a first transfer mechanism 3, an intermediate conveying mechanism 5, a detection mechanism 6, a second transfer mechanism 7 and a discharge mechanism 8 are arranged; the feeding mechanism 2 is used to convey the products to be wrapped, the products to be wrapped are transferred to the paper wrapping mechanism 4 via the first transfer mechanism 3 for the paper wrapping process, the wrapped products are transferred to the second transfer mechanism 7 via the intermediate conveying mechanism 5, the second transfer mechanism 7 transfers the products to the detection mechanism 6 for functional detection, and the products with normal functional detection are transferred to the discharge mechanism 8 via the second transfer mechanism 7 for recycling.
[0022] Specifically, the product is transferred to the paper wrapping mechanism 4 via the first transfer mechanism 3 for paper wrapping. After the paper wrapping is completed, the first transfer mechanism 3 moves the product to the intermediate conveying mechanism 5, and the intermediate conveying mechanism 5 moves the product to the starting end of the detection mechanism 6. Then the second transfer mechanism 7 moves the product to the detection mechanism 6 for functional testing. If the product function test passes, that is, the product is a qualified product, the second transfer mechanism 7 moves the product to the unloading mechanism 8 for recycling. The transformer paper wrapping detection equipment can simultaneously complete the paper wrapping and functional testing of the product, and is fully automated, effectively reducing labor costs, thereby improving product production efficiency, while improving product production accuracy, thereby improving product yield, and reducing unstable factors caused by manual production.
[0023] This embodiment provides a fully automatic transformer paper packaging inspection machine, such as Figure 1 and Figure 2The paper wrapping mechanism 4 includes a paper tape feeding unit 41 fixed to the frame 1, a rotating chassis 42 rotatably arranged on the frame 1, a product fixing seat 43 rotatably arranged on the rotating chassis 42 and used to fix the product, and a first driving unit for driving the rotating chassis 42 and the product fixing seat 43 to rotate, and the first driving unit is arranged at the bottom of the frame 1; the number of the product fixing seats 43 is set to two, and the two product fixing seats 43 are arranged on the rotating chassis 42 at intervals, specifically, the two product fixing seats 43 are symmetrically arranged on the rotating chassis 42 with the rotation center of the rotating chassis 42 as the center; the top of the product fixing seat 43 is provided with a card slot 45 for fixing the product; the paper wrapping mechanism 4 also includes a cutting unit 46 arranged on the frame 1, and the cutting unit 46 includes a first cylinder 47 and a cutter 48 driven and connected to the first cylinder 47, and the cutter 48 is used to cut the paper tape between two products respectively assembled on the two product fixing seats 43. Preferably, the first driving unit (not shown in the figure) can use multiple motors to respectively control the two product fixing seats 43 and the rotating chassis 42. For example, the first driving unit includes a first motor, a second motor and a third motor. The first motor is used to drive the rotating chassis 42 to rotate, and the second motor and the third motor are used to drive the two product fixing seats 43 to rotate, so that the rotation of the rotating chassis 42 and the rotation of the two product fixing seats 43 are independent of each other; the paper tape loading unit 41 can use the existing bracket to lift the paper tape roll.
[0024] Specifically, the first transfer mechanism 3 transfers the product at the discharge end of the feeding mechanism 2 and places it in the card slot 45 on the product fixing seat 43, so that the product is fixed in the card slot 45, and then the paper tape is attached to one side of a product close to the paper tape feeding unit 41, and the first driving unit drives the first product fixing seat 43 with the paper tape to rotate one circle, so that the paper tape wraps the product, and then the first driving unit drives the rotating chassis 42 to rotate 180 degrees, so that the paper tape is attached to the product on the second product fixing seat 43, and at this time, the first cylinder 47 drives the cutter 48 to cut the paper tape between the two products. After cutting, the first driving unit drives the second product fixing seat 43 to rotate one circle so that the second product is also wrapped with the paper tape. At the same time, the second transfer mechanism 7 transfers the first product wrapped with the paper tape to the detection mechanism 6 for detection, and the first transfer mechanism 3 places the product to be wrapped on the feeding mechanism 2 onto the first product fixing seat 43 again. Therefore, after the second product is wrapped, the rotating chassis 42 can be rotated 180° to continue wrapping the product. By repeating the above working process, the product can be automatically wrapped continuously, which effectively improves the working efficiency.
[0025] This embodiment provides a transformer paper packaging detection device, such as Figure 1The first transfer mechanism 3 includes a first bracket 31 fixed on the frame 1, a translation unit 32 slidably connected to the first bracket 31, two first finger cylinders 33 spaced apart on the translation unit 32, and a second cylinder 34 arranged on the first bracket 31 and used to drive the translation unit 32 to rise and fall. The translation unit 32 is used to drive the two first finger cylinders 33 to move horizontally.
[0026] Specifically, the two first finger cylinders 33, the first finger cylinder 33 close to the feeding mechanism 2 is used to clamp the product at the discharge end of the feeding mechanism 2, and the first finger cylinder 33 close to the paper wrapping mechanism 4 is used to clamp the wrapped product on the paper wrapping mechanism 4, and then through the translation of the translation unit 32, the two first finger cylinders 33 move simultaneously, and move the unwrapped product and the wrapped product to the paper wrapping mechanism 4 and the intermediate conveying mechanism 5 respectively. The first transfer mechanism 3 has a simple structure and can move the unwrapped and wrapped products at the same time, thereby effectively improving the production efficiency.
[0027] This embodiment provides a transformer paper packaging detection device, such as Figure 1 The detection mechanism 6 includes a pressure-resistant detection table 61 for detecting the pressure-resistant performance of the product and a defective product recovery channel 62 for recovering defective products. The pressure-resistant detection table 61 is provided with a first holder 63 for fixing the product, and the defective product recovery channel 62 is arranged between the pressure-resistant detection table 61 and the unloading mechanism 8; a product placement table 64 is arranged between the intermediate conveying mechanism 5 and the pressure-resistant detection table 61, and the product placement table 64 is provided with a second holder 65 for placing undetected products; the second transfer mechanism 7 includes a second slide rail 71 arranged on the frame 1 and a clamping unit 72 slidably connected to the second slide rail 71. The number of the clamping units 72 is three groups, and the three groups of clamping units 72 are arranged at intervals. The clamping unit 72 includes a third cylinder 73 slidably connected to the second slide rail 71 and a second finger cylinder 74 drivingly connected to the output end of the third cylinder 73. The second finger cylinder 74 is used to clamp the product and move it to the first holder 63 and the second holder 65. Preferably, the withstand voltage test station 61 is a detector used in the prior art to detect the withstand voltage performance of a transformer.
[0028] Specifically, three groups of clamping units 72 are arranged at intervals on the second slide rail 71. The first group of clamping units 72 near the discharge end of the intermediate conveying mechanism 5 is used to transfer the product at the discharge end of the intermediate conveying mechanism 5 to the second holder 65 on the product placement table 64. The second group of clamping units 72 located in the middle of the three groups of clamping units 72 is used to move the product in the second holder 65 to the first holder 63 for pressure resistance testing. The third group of clamping units 72 near the unloading mechanism 8 is used to transfer the tested product on the first holder 63 to the unloading mechanism 8 or the defective product recovery channel 62. The production efficiency can be further improved by the coordinated work of the three groups of clamping units 72; the product placement table 64 is set for the transition between the intermediate conveying mechanism 5 and the pressure resistance testing table 61, which can reduce the moving distance of each group of clamping units 72, thereby reducing possible errors in the movement and effectively improving the accuracy of product movement.
[0029] This embodiment provides a transformer paper packaging detection device, such as Figure 1 The feeding mechanism 2 includes a first conveying unit 21 for moving the paper product to be wrapped, a material blocking member 22 arranged at the discharge end of the first conveying unit 21, and a first infrared detection member 23 for detecting whether there is a product at the discharge end of the first conveying unit 21.
[0030] Specifically, the first conveying unit 21 can adopt structures such as conveyor belts in the existing technology. The products move side by side on the first conveying unit 21, so that the first transfer mechanism 3 can accurately clamp and transfer a single product; when the product moves to the discharge end of the first conveying unit 21, it is blocked by the blocking member 22 and cannot move forward. After the first transfer mechanism 3 clamps and transfers the product at the front end, the remaining products continue to move forward under the conveyance of the first conveying unit 21 until they abut against the blocking member 22; a first infrared detection member 23 is provided to detect whether there is any product abutting against the blocking member 22. If not, it means that there is no product on the first conveying unit 21, and the staff is notified that they need to continue to add products.
[0031] This embodiment provides a transformer paper packaging detection device, such as Figure 1 The intermediate conveying mechanism 5 includes a moving channel 51 arranged on the frame 1, a pushing block 52 arranged at the feeding end of the moving channel 51, a fourth cylinder 53 for driving the pushing block 52 to translate back and forth, and a second infrared detection component 54 arranged at the discharging end of the moving channel 51, and the second infrared detection component 54 is used to detect whether there is a product at the discharging end of the moving channel 51.
[0032] Specifically, after the product moves to the feeding end of the moving channel 51, the fourth cylinder 53 drives the push block 52 to move, pushing the product forward on the moving channel 51, and multiple products are placed in a row on the moving channel 51. Therefore, when the number of products on the moving channel 51 is sufficient, the second infrared detection member 54 can detect that there are products at the discharging end of the moving channel 51, and then the products at the discharging end of the moving channel 51 are transferred to the detection mechanism 6 through the second transfer mechanism 7. The intermediate transmission mechanism 5 has a simple structure, and can automatically detect whether there are enough products on the moving channel 51 through the second infrared detection member 54. When there are no products at the discharging end of the moving channel 51, the second transfer mechanism 7 can be stopped, thereby saving resources.
[0033] This embodiment provides a transformer paper packaging detection device, such as Figure 1 The unloading mechanism 8 includes a second conveying unit 81, a product recovery tray 82 arranged at the discharge end of the second conveying unit 81, and a third infrared detection member 83 arranged on the frame 1 for detecting whether there is a product passing through the discharge end of the second conveying unit 81.
[0034] Specifically, the third infrared detection element 83 is used to detect whether there is a product moving in the second conveying unit 81, so that it is possible to monitor in real time whether the product is being produced.

Although the present invention is disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
