Detailed Implementation

[0020] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-6 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0021] See Figure 1-6 An automatic contact piece inspection device includes a placement seat 20 for placing a product 10 containing contact pieces, a first conveying mechanism 1 for reciprocating transport of the placement seat 20, a second conveying mechanism 2 installed parallel to and at intervals behind the end of the first conveying mechanism 1, and a defective box 3 fixed to the front of the end of the first conveying mechanism 1. It also includes, sequentially arranged on the first conveying mechanism 1, a feeding station 4 for placing the product 10 onto the placement seat 20, a positioning mechanism 5 for positioning the contact pieces of the product 10 on the placement seat 20, a first inspection mechanism 6 for visually inspecting the top surface of the positioned contact pieces of the product 10 on the placement seat 20, a second inspection mechanism 7 for visually inspecting the side surface of the contact pieces of the product 10 on the placement seat 20 after the first inspection, and a transport mechanism 8 for transporting the qualified product 10 on the placement seat 20 to the beginning of the second conveying mechanism 2 or for transporting the unqualified product 10 on the placement seat 20 to the defective box 3.

[0022] The automatic contact piece detection device of this utility model involves placing a product 10 containing contact pieces onto a placement seat 20 at the feeding station 4. The positioning mechanism 5 positions and shapes the contact pieces of the product 10 on the placement seat 20. The first detection mechanism 6 performs visual inspection on the top surface of the contact pieces of the product 10 on the placement seat 20 (specifically, it detects the spacing between the springs of the contact pieces). The second detection mechanism 7 performs visual inspection on the side surface of the contact pieces of the product 10 on the placement seat 20 (specifically, it detects the height of the springs of the contact pieces). If both inspections are qualified, the transport mechanism 8 transports the product 10 on the placement seat 20 to the beginning of the second conveying mechanism 2 and sends it to the next process. If at least one inspection fails, the transport mechanism 8 transports the product 10 on the placement seat 20 to the defective product box 3. The detection speed is fast, the detection time can be reduced to 8 seconds, and there is no defect rate. It is also convenient to use.

[0023] In this embodiment, the positioning mechanism 5 includes a support frame 51, a first cylinder 52 fixed to the top of the support frame 51, a mounting base 53 fixed to the bottom output end of the first cylinder 52, and a positioning block 54 fixed to the bottom of the mounting base 53. The above structure facilitates the positioning and shaping of the contact piece of the product 10.

[0024] In this embodiment, the support frame 51 includes a fixed plate 511 fixed above the first conveying mechanism 1 and four support columns 512 fixed at the four corners of the bottom of the fixed plate 511. Guide columns 55 are fixed on both sides of the top of the mounting base 53, and two guide columns 55 pass upward through the fixed plate 511 and are slidably connected to it. Specifically, bushings 56 are embedded in the fixed plate 511 at positions corresponding to the two guide columns 55, and the two guide columns 55 are slidably connected within the corresponding bushings 56. This structure facilitates smooth up-and-down movement of the positioning block 54.

[0025] In this embodiment, the first detection mechanism 6 includes a first CCD lens 61 vertically fixed above the end of the first conveying mechanism 1, and the second detection mechanism 7 includes a second CCD lens 71 horizontally fixed above the beginning of the second conveying mechanism 2. The vertically fixed first CCD lens 61 is used to detect the spacing between the contact springs, and the horizontally fixed second CCD lens 71 is used to detect the height of the contact springs.

[0026] In this embodiment, the conveying mechanism 8 includes a first gripping mechanism 81 installed above the end of the first conveying mechanism 1, a second gripping mechanism 82 installed above the beginning of the second conveying mechanism 2, and a moving mechanism 83 for driving the first gripping mechanism 81 and the second gripping mechanism 82 to move synchronously back and forth and up and down. By moving the first gripping mechanism 81 and the second gripping mechanism 82 synchronously, equipment costs can be reduced. Specifically, the front and rear distances between the end of the first conveying mechanism 1 and the beginning of the second conveying mechanism 2, and between the defective product box 3, are approximately equal. When both tests are passed, the moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move forward to the end of the first conveying mechanism 1 and above the defective product box 3, respectively. Then, it drives the first clamping mechanism 81 and the second clamping mechanism 82 to move downward. The second clamping mechanism 82 clamps the product 10 on the placement seat 20 and then moves upward. The moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move backward. At this time, the first clamping mechanism 81 and the second clamping mechanism 82 are located above the end of the first conveying mechanism 1 and the beginning of the second conveying mechanism 2, respectively. Then, the moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move downward. The second clamping mechanism 82 places the product 10 on the beginning of the second conveying mechanism 2. When at least one inspection fails, the moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move backward to above the end of the first conveying mechanism 1 and the beginning of the second conveying mechanism 2, respectively. Then, the moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move downward. The first clamping mechanism 81 clamps the product 10 on the placement seat 20 and then moves upward. The moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move forward. At this time, the first clamping mechanism 81 and the second clamping mechanism 82 are located above the end of the first conveying mechanism 1 and the defective product box 3, respectively. Then, the moving mechanism 83 drives the first clamping mechanism 81 and the second clamping mechanism 82 to move downward. The first clamping mechanism 81 places the product 10 into the defective product box 3.

[0027] In this embodiment, the moving mechanism 83 includes a gantry frame 831 spanning and fixed above the first conveying mechanism 1, a first sliding block 832 slidably connected to the top left side of the gantry frame 831, a second cylinder 833 driving the first sliding block 832 to move back and forth, a second sliding block 834 slidably connected to the left side of the first sliding block 832, a third cylinder 835 driving the second sliding block 834 to move up and down, and a mounting block 836 horizontally fixed to the left side of the second sliding block 834. The first clamping mechanism 81 and the second clamping mechanism 82 are respectively fixed to the front and rear ends of the bottom of the mounting block 836. The above structure facilitates the synchronous back-and-forth and up-and-down movement of the first clamping mechanism 81 and the second clamping mechanism 82. Specifically, the second cylinder 833 drives the first sliding block 832 to move the first clamping mechanism 81 and the second clamping mechanism 82 back and forth, and the third cylinder 835 drives the second sliding block 834 to move the first clamping mechanism 81 and the second clamping mechanism 82 up and down.

[0028] In this embodiment, the second gripping mechanism 82 is equipped with a rotating mechanism 84 for rotating the gripped product 10 by 90°. The product 10 on the placement seat 20 is placed horizontally. When the next process requires vertical placement, the gripped product 10 can be rotated 90° and placed on the second conveying mechanism 2 by the rotating mechanism 84.

[0029] In this embodiment, the first conveying mechanism 1 is driven by a first motor 11 and a lead screw 12. Specifically, a movable seat 13 is fixed to the bottom of the placement seat 20, and the bottom of the movable seat 13 is screwed onto the lead screw 12. The first motor 11 drives the lead screw 12 to rotate, thereby realizing the left and right movement of the placement seat 20 on the movable seat 13. The second conveying mechanism 2 is driven by a second motor 21 and a conveyor belt 22. The conveyor belt 22 is sleeved on two rollers 23, one of which has a driven wheel 24 coaxially fixed. The driven wheel 24 is connected to the driving wheel 26 fixed to the output end of the second motor 21 via a belt 25. The second motor 21 drives the driving wheel 26 to rotate, thereby driving the driven wheel 24 to rotate via the belt 25. The two rollers 23 further drive the conveyor belt 22 to move to the left, so as to convey the product 10 on the conveyor belt 22 to the next station. Of course, in other embodiments, the second motor 21 can also directly drive one of the rollers 23 to rotate, thereby driving the conveyor belt 22 to move to the left.

[0030] The automatic contact piece detection device of this utility model also includes a control box 9 and multiple proximity sensors (for detecting the movement of products to each workstation). The control box 9 is electrically connected to the aforementioned cylinder, motor and multiple sensors to realize the automated operation of the device. The above structure is prior art and will not be described in detail here.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
