Description

Technical Field

[0001] The present invention relates to the technical field of electronic product production, and specifically relates to a continuous detection and marking device for electronic assembly products. Background Art

[0002] An electronic assembly product refers to an electronic product with a specific function formed by connecting electronic components, assemblies, modules, etc. according to design requirements through welding, plugging, crimping, etc. After the production of some electronic assembly products with high requirements for waterproofness and high temperature resistance, it is necessary to test the waterproofness and high temperature resistance performance;

[0003] For example, a rain shower test device for electronic product detection proposed in the currently authorized announcement number CN115112301B includes a bottom plate and mounting buckles; two mounting buckles are fixedly connected to the left and right parts of the bottom plate respectively; it also includes a first hemispherical body, a second hemispherical body, a keel frame, a spray pipe, a water supply system, a water spraying system and an immersion unit; this device can realize the spray and immersion tests of electronic products.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 - 13 , in the embodiment of the present invention, a continuous detection and marking device for electronic assembly products includes an installation chassis 1. A pick-and-place opening 12 is provided on one side of the installation chassis 1. The provided pick-and-place opening 12 can be used to pick and place products in a targeted manner. Inside the installation chassis 1, a soaking chamber 13, a high-temperature test area 15, and a marking chamber 14 are sequentially arranged from bottom to top. A plurality of top through holes 10 communicating with the marking chamber 14 are provided on the upper end surface of the installation chassis 1. A fixed shaft 6 is fixedly connected in the middle of the installation chassis 1, and a hollow rotating roller 11 is rotatably connected to the fixed shaft 6;

[0044] A product carrier 4 for fixing products is provided on the hollow rotating roller 11. The product carrier 4 includes a hollow side block 44. The hollow side block 44 is fixedly connected to both ends of the hollow rotating roller 11. Rotating end shafts 47 are rotatably connected to both hollow side blocks 44. A cover plate frame 42 is fixedly connected between the two rotating end shafts 47. A product placement module 43 is rotatably connected to the matching cover plate frame 42. Limiting bars 41 are fixedly connected to both sides of the product slots of the cover plate frame 42 and the product placement module 43. Lock holes 46 are provided on both sides of one end of the cover plate frame 42 away from the hollow rotating roller 11. A fixing component for fixing the cover plate frame 42 in cooperation with the lock holes 46 is provided on the product placement module 43. A counterweight magnetic strip 49 is fixedly connected to one end of the product placement module 43 away from the lock holes 46. A locking component for locking the product placement module 43 in cooperation with the counterweight magnetic strip 49 is provided inside the hollow rotating roller 11. First friction discs 48 are rotatably connected to positions near the hollow side blocks 44 at one end inside the hollow rotating roller 11. Transmission pulleys 45 are installed on the connecting shafts of the first friction discs 48 and the rotating end shafts 47. A transmission belt 40 is provided between the two transmission pulleys 45. A transmission component 60 for driving the first friction disc 48 to rotate is provided on the installation chassis 1.

[0045] During use, the product placement module 43 provided can be used for placing the product. Meanwhile, the limit bars 41 provided on the product placement module 43 and the cover plate frame 42 can limit the product, enabling the product to be stably placed in the product slot of the product placement module 43. At the same time, the limit bars 41 only limit the edge of the product and will not block the product, facilitating subsequent detection. The fixed component provided can be used to lock the cover plate frame 42 to prevent the product from falling during the detection process. The locking component provided can lock the position of the product placement module 43 when the product placement module 43 passes through the marking chamber 14 and the pick-and-place opening 12, preventing the product placement module 43 from shaking or rotating. The fixed shaft 6 provided is used to drive the product to rotate when the product placement module 43 passes through the immersion chamber 13 and the high-temperature test area 15, so as to facilitate better testing.

[0046] The fixed component includes an L-shaped guide groove 435, which is opened at positions on both sides of the product placement module 43 that match the lock holes 46. An L-shaped lock plate 432 is slidably connected in each of the L-shaped guide grooves 435. A rotating column 433 is rotatably connected to the lower end of the L-shaped lock plate 432. A second spring 434 is installed between the L-shaped lock plate 432 and the side of the L-shaped guide groove 435 close to the middle of the product placement module 43. The installation chassis 1 is also provided with an inclined plane guide block 431 that cooperates with the rotating column 433 to push the L-shaped lock plate 432 to unlock. Through the provided L-shaped lock plate 432 and the second spring 434, the cover plate frame 42 can be locked in cooperation with the lock holes 46 during use. When the product placement module 43 runs to the position of the pick-and-place opening 12, the inclined plane guide block 431 will squeeze the rotating column 433 to release the locking of the cover plate frame 42 by the L-shaped lock plate 432, so that when the product placement module 43 runs to the pick-and-place opening 12 during use, the locking of the cover plate frame 42 can be automatically released, facilitating the staff to pick and place the product.

[0047] The locking assembly includes a cam 116, which is fixedly connected to the fixed shaft 6. The upper end of the fixed shaft 6 is also fixedly connected to a permanent magnet 117 that matches the counterweight magnetic strip 49. A gap is left between the permanent magnet 117 and the inner wall of the hollow roller 11. Both ends of the counterweight magnetic strip 49 are provided with a latch hole 112. The positions of the hollow roller 11 that match the latch hole 112 are slidably connected to a latch rod 113. The latch rod 113 is located inside the hollow roller 11 and is fixedly connected to a limit baffle 111. A first spring 114 is installed between the limit baffle 111 and the inner wall of the hollow roller 11. The latch rod 113 is close to the cam 116. A roller 115 is provided at one end; during operation, when the product placement module 43 reaches the position of the marking chamber 14, the counterweight magnetic strip 49 will be oriented towards the permanent magnet 117 under the action of gravity and magnetic force, and at the same time, the roller 115 contacts the cam 116, and the locking rod 113 is inserted into the locking hole 112 under the action of the cam 116 to lock the product placement module 43. Since the cam 116 extends to the position of the take-and-place port 12, when the product placement module 43 passes through the take-and-place port 12, the product placement module 43 is still in a locked state. When the roller 115 disengages from the cam 116, the locking rod 113 disengages from the locking hole 112 under the action of the first spring 114, and the lock is released.

[0048] The transmission assembly 60 includes an installation box 69 which is installed at a position on one side of the installation chassis 1. At both ends inside the installation box 69, there are rotatably connected spline sleeves 65. Inside each spline sleeve 65, there is a slidably connected spline shaft 67. One end of the spline shaft 67 located inside the installation chassis 1 is fixedly connected to a second friction disk 64 that mates with the first friction disk 48. Between the ends of the spline shaft 67 away from the second friction disk 64, there is a rotatably connected iron connecting plate 68. A third spring 62 is disposed through the spline shaft 67 between the spline sleeve 65 and the iron connecting plate 68. On both sides of the installation box 69, there are electromagnets 63 that mate with the iron connecting plate 68. On both spline sleeves 65, there are installed spur gears 66, and the two spur gears 66 mesh with each other. At opposite ends of the spline sleeve 65 and the drive shaft 51, there are installed bevel gears 61, and the two bevel gears 61 mesh with each other. During operation, the drive shaft 51 drives the bevel gear 61 to rotate, and the bevel gear 61 drives the spline sleeve 65. At the same time, the two spur gears 66 mesh with each other, enabling the two spline sleeves 65 to rotate simultaneously. The rotation of the two spline sleeves 65 can drive the spline shaft 67 to rotate. When it is necessary to drive the product placement module 43 to rotate, the electromagnet 63 is activated to attract the iron connecting plate 68. After the iron connecting plate 68 is attracted, it drives the second friction disk 64 to engage with the first friction disk 48 for transmission, thereby driving the transmission belt 40 and the transmission pulley 45, and then driving the rotating end shaft 47. The rotation of the rotating end shaft 47 can drive the product placement module 43 to perform corresponding rotation. When the electromagnet 63 is powered off, the iron connecting plate 68 resets under the action of the third spring 62. At this time, the second friction disk 64 is separated from the first friction disk 48, interrupting the power transmission.

[0049] On one side of the installation chassis 1, there is also a drive assembly 7 for driving the hollow roller 11 to rotate. The drive assembly 7 includes a protruding sleeve 73 which is fixedly connected to a position at one end of the hollow roller 11. The protruding sleeve 73 is rotatably connected to the fixed shaft 6. Near the immersion chamber 13 on one side of the installation chassis 1, a servo motor 72 is installed. Synchronous belt pulleys 74 are installed at the output end of the servo motor 72 and on the protruding sleeve 73, and a synchronous belt 71 is installed between the two synchronous belt pulleys 74. During operation, the servo motor 72 drives the synchronous belt pulley 74 and the synchronous belt 71 to rotate, thereby driving the hollow roller 11 to rotate, causing the hollow roller 11 to rotate 90 degrees each time to achieve the position switching of the product placement module 43.

[0050] A water immersion test assembly 3 for performing a water immersion test on a product is provided in the water immersion chamber 13. The water immersion test assembly 3 includes a drain pipe 31. The drain pipe 31 is provided at the lower end of the installation chassis 1. The drain pipe 31 communicates with the water immersion chamber 13. A drain valve is provided on the drain pipe 31. A water supply pipe 32 is provided at the position of the installation chassis 1 above the water immersion chamber 13. A test liquid is poured into the water immersion chamber 13 through the water supply pipe 32. By providing the water immersion chamber 13, water can be injected during use, facilitating the waterproof test of the product. At the same time, the drain pipe 31 is provided to facilitate the discharge of water in the water immersion chamber 13.

[0051] A high-temperature test assembly 5 for performing a high-temperature resistance test on a product is provided in the high-temperature test area 15. The high-temperature test assembly 5 includes a rectangular sliding groove 53. The rectangular sliding groove 53 is opened on the side of the installation chassis 1 away from the access opening 12. A sliding plate 52 is slidably connected in the rectangular sliding groove 53. Hot air blowers 54 are installed on both sides of the sliding plate 52. A middle frame 55 is fixedly connected to the lower end of the sliding plate 52. A drive shaft 51 is rotatably connected to one side of the installation chassis 1. A drive motor 59 is installed at the lower end of one side of the installation chassis 1. Drive pulleys 57 are installed at one end of the drive shaft 51 and the output end of the drive motor 59. A transmission belt 58 is installed between the two drive pulleys 57. Connecting rods 56 are rotatably connected to the edges of the drive pulleys 57. One end of the connecting rod 56 away from the drive pulley 57 is rotatably connected to the lower end of the middle frame 55. During operation, the drive motor 59 can drive the transmission belt 58 and the drive pulleys 57 to operate. The operation of the drive pulley 57 can drive the connecting rod 56 to move. The movement of the connecting rod 56 can drive the sliding plate 52 to reciprocate, and further drive the hot air blowers 54 to reciprocate. The reciprocating movement of the hot air blowers 54 can make the product receive more uniform hot air baking. At the same time, combined with the rotation of the product placement module 43, the high-temperature resistance test of the product can be realized. When performing the high-temperature resistance test, the water stains on the surface of the product can also be removed to facilitate subsequent functional testing and marking operations.

[0052] On one side of the marking chamber 14, there is an electrified test component 8 for performing an electrified test on the product. The electrified test component 8 includes a first lead screw transverse movement module 81. The first lead screw transverse movement module 81 is installed at a position on the upper side of one side of the marking chamber 14. A first lead screw lifting module 82 is installed at the moving end of the first lead screw transverse movement module 81. An electric push rod 84 is installed at the moving end of the first lead screw lifting module 82. A connection plug 83 matching the product is provided at the output end of the electric push rod 84. On the other side of the marking chamber 14, there is also a laser marking component 9 for marking qualified products. The laser marking component 9 includes a second lead screw transverse movement module 91. The second lead screw transverse movement module 91 is installed at a position on the upper side of the other side of the immersion chamber 13. A second lead screw lifting module 92 is installed at the moving end of the second lead screw transverse movement module 91. A laser marker 93 for marking the product is installed at the moving end of the second lead screw lifting module 92. A main control computer 2 is also provided at a position above the pick-and-place opening 12 of the installation chassis 1. During operation, the first lead screw transverse movement module 81 drives the connection plug 83 to move transversely, the first lead screw lifting module 82 drives the connection plug 83 to move vertically, and the electric push rod 84 pushes the connection plug 83 to insert the connection plug 83 into the power interface of the product, realizing the electrified test of the product. At the same time, the second lead screw transverse movement module 91 drives the laser marker 93 to move transversely, and the second lead screw lifting module 92 drives the laser marker 93 to move vertically. After the connection plug 83 performs an electrified test on the product, if the product is normal, the laser marker 93 performs a marking operation on the current product. If the product is unqualified, this product is skipped and not marked, so as to facilitate subsequent staff to sort out unqualified products.

[0053] The working principle of the present invention is as follows: During operation, first place the product to be detected in the product slot of the product placement module 43, then cover the cover frame 42, and then the driving assembly 7 drives the hollow rotating roller 11 to rotate intermittently by 90 degrees. The rotation of the hollow rotating roller 11 drives the product placement module 43 to rotate. When the product placement module 43 moves downward, the rotating column 433 disengages from the inclined plane guide block 431, and the L-shaped locking plate 432 locks the cover frame 42 under the action of the second spring 434. At the same time, the roller 115 disengages from the cam 116, and the plug lock rod 113 is withdrawn from the plug lock hole 112 to release the locking of the product placement module 43. Then, the electromagnet 63 is activated to attract the iron connecting plate 68. After the iron connecting plate 68 is attracted, it drives the second friction disk 64 to engage with the first friction disk 48 for transmission, thereby driving the transmission belt 40 and the transmission belt pulley 45, and then driving the rotating end shaft 47. The rotation of the rotating end shaft 47 drives the product placement module 43 to rotate accordingly. The product placement module 43 rotates and moves in the water in the immersion chamber 13, so that the product is impacted by water to facilitate better testing of the waterproof performance. When the product placement module 43 moves to the high-temperature test area 15, the drive motor 59 drives the transmission belt 58 and the drive belt pulley 57 to operate. The operation of the drive belt pulley 57 drives the connecting rod 56 to move. The movement of the connecting rod 56 drives the sliding plate 52 to reciprocate, and then drives the hot air blower 54 to reciprocate. The reciprocating movement of the hot air blower 54 makes the product be baked by hot air more evenly. At the same time, combined with the rotation of the product placement module 43, the high-temperature resistance test of the product can be realized. During the high-temperature resistance test, the water stains on the product surface can also be removed to facilitate subsequent functional testing and marking operations. When the product placement module 43 runs to the marking chamber 14, the power-on test assembly 8 conducts power-on tests on the products one by one, and at the same time, the laser marking assembly 9 marks the products that pass the test. After the power-on test and marking are completed, the product placement module 43 runs to the pick-up and placement port 12 again.
