[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] The strip circuit board appearance inspection machine provided by the preferred embodiment of the utility model includes a loading and unloading device and a detection device, and the loading and unloading device is used for loading and unloading the strip circuit board on the detection device. There are two loading and unloading devices, namely a loading device and a unloading device, and the detection device is connected between the loading device and the unloading device. The loading device is used to supply the strip circuit board to be inspected to the detection device, the detection device is used to detect the strip circuit board, and the unloading device is used to receive the strip circuit board that has been inspected on the detection device. The loading device and the unloading device have the same structure. In this embodiment, the structure of the loading and unloading device is described by taking the loading device as an example.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3 The loading equipment includes a material frame 1, a trolley 2, a rack 100, a receiving platform 110 and a receiving mobile device 3. The material frame 1 is used to place multiple strip circuit boards 900. The receiving platform 110 and the receiving mobile device 3 are arranged on the rack 100. The material frame 1 can be transferred between the trolley 2 and the receiving platform 110.

[0029] The plurality of strip circuit boards 900 are equally divided into a plurality of piles and arranged on the material frame 1 in a horizontal direction. The strip circuit boards 900 in each pile are stacked and arranged, and the length direction of the strip circuit boards 900 is longitudinal. The strip circuit boards 900 located in the same layer are grouped together. A group of strip circuit boards can be transported simultaneously by using the receiving and moving device 3, and the whole board and appearance inspection and other operations can be carried out simultaneously on the inspection equipment. In this embodiment, a group of strip circuit boards is 4.

[0030] like Figure 4 , Figure 5As shown, a plurality of limit frames 11 are provided on the material frame 1, and a plurality of stacks of strip circuit boards 900 are separated by the limit frames 11. The limit frames 11 can be used to maintain a certain interval between two adjacent stacks of strip circuit boards 900, so as to facilitate the taking and placing of the strip circuit boards 900. The plurality of limit frames 11 are arranged on the material frame 1 in a lateral sliding manner to adjust the gap between the limit frames 11 to match the width of the strip circuit board 900. The gap between the limit frames 11 can be slightly larger than the width of the strip circuit board 900, so as to avoid the shaking of the strip circuit board 900 and not affect the taking and placing of the strip circuit board 900 from the limit frames 11. In this embodiment, the widths of all the strip circuit boards 900 in the material frame 1 are the same, and the plurality of limit frames 11 are arranged at equal intervals, and can be adjusted at equal intervals to match the width of the strip circuit board 900.

[0031] The material frame 1 is detachably arranged on the trolley 2 so as to be transferred between the trolley 2 and the receiving platform 110. The trolley 2 is used to carry the material frame 1 and drive the material frame to move. The receiving platform 110 and the receiving and moving device 3 are both arranged on the frame 100. The receiving platform is located below the receiving and moving device 3 and is used to receive the material frame 1. The receiving and moving device 3 is used to move the strip circuit board 900 between the material frame 1 and the detection device.

[0032] A plurality of strip circuit boards 900 are stacked on a material frame 1. The cooperation of the trolley 2 and the material frame 1 can simultaneously transport a plurality of strip circuit boards 900, thereby improving the transport efficiency. The receiving and moving device 3 of the loading equipment can move a group of strip circuit boards 900 in the material frame 1 to the detection equipment for appearance inspection of the strip circuit boards. After inspection, a group of strip circuit boards 900 can be moved to the material frame of the unloading equipment via the receiving and moving device 6 of the unloading equipment, and the strip circuit boards after inspection are stacked again on the material frame, thereby facilitating overall transport and effectively improving the conveying efficiency.

[0033] The material frame 1 includes a bottom plate 12, a support plate 13, a first baffle 14, a second baffle 15 and an adjustment mechanism 16. The bottom plate 12 and the support plate 13 are both square and arranged in parallel. The support plate 13 is located above the bottom plate 12 and is used to support the strip circuit board 900. The first baffle 14 and the second baffle 15 are both arranged vertically. The bottom edge of the first baffle 14 and the bottom edge of the second baffle 15 are respectively fixedly connected to the two adjacent edges of the bottom plate 12; the first baffle 14 and the second baffle 15 limit the two edges of the strip circuit board 900 from two directions respectively. The first baffle 14, the second baffle 15, and the upper part of the support plate 13 form a storage space for accommodating the strip circuit board 900. The material frame 1 limits the entirety of the plurality of strip circuit boards 900 from three adjacent sides through the first baffle 14, the second baffle 15 and the support plate 13, and the other three adjacent sides are open, so as to facilitate the loading of the strip circuit board 900 into the material frame 1. Multiple limit frames 11 are connected to the base plate 12 in a transverse sliding manner, and the adjustment mechanism 16 is connected to the multiple limit frames 11, which is used to adjust the multiple limit frames 11 at equal intervals to match the width of the strip circuit board 900, so as to adapt to strip circuit boards 900 of different widths, so that the multiple strip circuit boards 900 can be reliably limited on the material frame 1 to avoid shaking and collapse and damage during transportation.

[0034] The limiting frame 11 includes a slide bar 111 and a vertical rod 112. The slide bar 111 is arranged longitudinally and slidably connected to the bottom plate 12. The vertical rod 112 is vertically fixed above the slide bar 111. A strip hole 130 is arranged horizontally on the upper edge of the support plate 13. The vertical rod 112 is penetrated by the strip hole 130 to extend to the top of the support plate 13, so as to limit the strip circuit board 900 through the vertical rod 112. The slide bar 111 and the bottom plate 12 are slidably connected to the slide bar 111, so that the slide bar 111 is located below the support plate 13, which is conducive to the sliding adjustment of the limiting frame 11. Two vertical rods 112 are arranged on each limiting frame 11. The two vertical rods 112 are arranged longitudinally at intervals. The two vertical rods 112 can play a better limiting role on the strip circuit board 900. The two vertical rods 112 are fixed to the middle position of the length direction of the slide bar 111. Of course, the positions of the two vertical rods 112 can also be set at other positions of the slide bar 111.

[0035] Both ends of the slide bar 111 are slidably connected to the top surface of the base plate 12 via a slide mechanism 17. The slide mechanism 17 includes matching sliders and guide rails. The sliders and guide rails are respectively connected to the slide bar 111 and the base plate 12 to ensure the stability of the slide bar 111 in moving relative to the base plate 12, which is beneficial for adjusting the position of the slide bar 111.

[0036] The adjustment mechanism 16 includes a scissor-fork linkage mechanism 161, a limit screw 162, an adjustment block 163 and an adjustment handle 164. The scissor-fork linkage mechanism 161 is arranged in the horizontal direction, and its end close to the first baffle 14 is connected to the base plate 12. The limit screw 162 is arranged in the horizontal direction and is connected to the base plate 12 around its own axial rotation. The adjustment block 163 is threadedly connected to the limit screw 162. The adjustment handle 164 is fixedly connected to one end of the limit screw 162 to drive the limit screw 162 to rotate. The sliding rods 111 of multiple limit frames 11 are respectively connected to each scissor node of the scissor-fork linkage mechanism 161, wherein a limit frame 11 farthest from the first baffle 14 is fixedly connected to the adjustment block 163 to move in a horizontal straight line under the drive of the adjustment block 163.

[0037] When the adjustment handle 164 drives the limiting screw rod 162 to rotate, the adjustment block 163 drives the other end of the scissor-fork link mechanism 161 to move horizontally by using the threaded cooperation between the adjustment block 163 and the limiting screw rod 162. Since one end of the scissor-fork link mechanism 161 is connected to the bottom plate, it can be telescopically moved, thereby driving the spacing between the multiple limiting frames 11 to be simultaneously reduced or expanded, and the spacing between the multiple limiting frames 11 can be adjusted. The adjustment mechanism 16 has a simple structure and is conducive to the simultaneous adjustment of the spacing.

[0038] The support plate 13 is vertically slidably connected to the first baffle plate 14 and / or the second baffle plate 15, so that the support plate 13 can be raised and lowered. In the process of testing the strip circuit boards 900 layer by layer, the strip circuit boards 900 are gradually reduced. By raising the support plate 13, the strip circuit boards 900 at the bottom are lifted to a higher position, so as to facilitate the transfer of the strip circuit boards 900 to the whole board position.

[0039] The trolley 2 is used to carry the material frame 1 and drive the material frame 1 to move, so as to realize the overall transportation of a large number of strip circuit boards.

The plurality of vehicle-mounted rollers 27 are arranged at intervals in the transverse direction, and their top surfaces are used to support the material frame 1. The plurality of vehicle-mounted rollers 27 can be used to conveniently remove the material frame 1 from the cart 2. The tops of the two connecting plates 26 can protrude from the top surfaces of the vehicle-mounted rollers 27, and the material frame 1 can be limited between the two connecting plates 26 in the longitudinal direction to limit the position of the material frame 1.

[0040] The armrest 24 is fixed to one side of the top of the frame 21, and the back plate 23 is fixed to the armrest 24. The armrest 24 is used to facilitate the user to push the cart 2. The armrest 24 cooperates with the back plate 23 to limit the material frame 1. When the material frame 1 is located on the frame 21, the back plate 23 and the first baffle 14 are arranged opposite to each other, and are respectively located at both sides of the cart 2 in the horizontal direction, that is, the back plate 23 is located at the rear side of the cart 2, and the first gear is located at the front side of the cart 2, and the front side of the cart 2 faces the frame 100.

The locking mechanism 22 is used to cooperate with the bottom plate 12 of the material frame 1 to be detachably connected so as to lock the material frame 1 on the cart 2 so that the material frame 1 will not move on the vehicle-mounted roller 27. In this embodiment, the locking mechanism 22 is a manual locking mechanism, and various mechanisms that can lock or clamp and position objects can be used. When the front side of the frame 21 is aligned with the loading position of the rack 100, the user can manually operate the locking mechanism 22 to unlock the material frame 1, and the material frame 1 can slide out from the front side of the frame 21 into the rack 100.

[0054] By means of the receiving and lifting driving member 321, the receiving manipulator 31 can be moved downward to approach the strip circuit board 900, and rise after adsorbing the strip circuit board 900. The receiving transverse driving member 323 drives the receiving manipulator 31 to move transversely to the top of the whole board device 4. The receiving manipulator 31 moves downward under the drive of the receiving and lifting driving member 321 to place a group of strip circuit boards 900 on the whole board device 4. Here, since the strip circuit boards 900 in the material frame 1 can be lifted and lowered under the drive of the lifting device 120, the receiving driving assembly 32 can only include the receiving transverse driving member 323. When the receiving manipulator 31 is located directly above the whole board device 4, the center distance between adjacent receiving manipulator arms 312 is equal to the preset center distance. In the process of the receiving transverse driving member 323 driving the receiving manipulator 31 to move transversely, the receiving adjustment mechanism 313 can simultaneously adjust the center distance between multiple receiving manipulator arms 312, so as to facilitate the placement of the strip circuit boards.

[0055] Combination Figure 1 , Figure 2 and Figure 3 As shown, the detection device includes a whole board device 4, a transfer device 5, two detection mobile devices 7, and two camera devices 8. The whole board device 4, the transfer device 5, the two detection mobile devices 7, and the two camera devices 8 can all be arranged on a frame, that is, the detection device and the loading and unloading device can share the same frame to make the structure more compact, or the detection device is also arranged on another structural frame.

[0056] The board-straightening device 4 is located between the receiving and moving device 3 and the transfer device 5 in the horizontal direction, and is used to carry a group of strip circuit boards 900 conveyed by the loading device and perform board straightening. The receiving and moving device 3 of the loading device can absorb a group of strip circuit boards 900 located at the uppermost layer of the material frame 1, and move the strip circuit boards 900 to the board-straightening device 4.

[0057] The transfer device 5 is used to move a group of strip circuit boards 900 after the whole board is formed from the whole board device 4 to the detection mobile device 7; the two detection mobile devices 7 are arranged in a horizontal direction, and each detection mobile device 7 is used to drive a group of strip circuit boards 900 to move in the longitudinal direction and pass through the camera device 8; the camera device 8 is arranged in a one-to-one correspondence with the detection mobile device 7, and the camera device 8 is located above the middle position of the detection mobile device 7 in the longitudinal direction, and is located between the transfer device 5 and the receiving mobile device 6 of the unloading equipment in the longitudinal direction; it is used to take pictures and detect the strip circuit boards 900 on the detection mobile device 7.

[0058] The unloading equipment is used to receive a group of strip circuit boards after inspection, such as Figure 3 As shown, the receiving and moving device 6 of the unloading equipment is used to move a group of strip-shaped circuit boards 900 after inspection from the inspection and moving device 7 to another material frame 1.

[0059] The utility model provides a strip circuit board 900 appearance inspection machine, where multiple strip circuit boards 900 are stacked on a material frame 1. The cooperation of the cart 2 and the material frame 1 can simultaneously transport multiple strip circuit boards 900, thereby improving the transport efficiency. The receiving and moving device 3 can move a group of strip circuit boards 900 in the material frame 1 to the whole board device 4. The whole board device 4 can whole board and position multiple strip circuit boards 900 in a group, so that they are arranged neatly, for the convenience of subsequent inspection. The inspection moving device 7 drives a group of strip circuit boards 900 after whole board to pass under the camera device 8 for camera inspection. The camera inspection process is slow, and the whole board process is fast. By setting the inspection moving device 7 into multiple groups, it is convenient to inspect multiple groups of strip circuit boards 900, which can effectively improve the inspection efficiency. The receiving and moving device 6 of the unloading equipment can move a group of strip circuit boards 900 after inspection from the inspection moving device 7 to another material frame 1. The strip circuit boards 900 after inspection are stacked again, which is convenient for overall transportation, thereby effectively improving the inspection efficiency.

[0060] The board-aligning device 4 is used to align multiple strip-shaped circuit boards 900 in a group in the horizontal and vertical directions. Of course, the board-aligning device 4 may not be provided, and the strip-shaped circuit boards may be directly moved from the material frame to the detection moving device.

[0061] like Figure 7 As shown, the transfer device 5 includes a transfer manipulator 51 and a transfer drive assembly 52. ​​The transfer drive assembly 52 is arranged on the frame 100 and connected to the transfer manipulator 51, and is used to drive the transfer manipulator 51 to move between the whole board device 4 and the detection moving device 7. There are two detection moving devices 7, which can detect two groups of strip circuit boards 900 at the same time. The detection moving device 7 includes a longitudinal moving drive member 71 and an adsorption platform 72. The adsorption platform 72 is used to adsorb and position a group of strip circuit boards 900. The adsorption platform 72 is provided with a plurality of detection positions arranged in the transverse direction, and the center distance between adjacent detection positions is a preset center distance. A plurality of adsorption holes are provided at the detection position to adsorb the strip circuit board on the adsorption platform 72. The transfer manipulator 51 moves a group of strip circuit boards 900 from the whole board device 4 to the adsorption platform 72. During the whole process, a group of strip circuit boards 900 maintain a fixed preset center distance, and no adjustment is required, thereby improving transportation efficiency.

[0062] The longitudinal moving driving member 71 is fixed to the frame 100 and connected to the adsorption platform 72, and is used to drive the adsorption platform 72 to move longitudinally. In this embodiment, the longitudinal moving driving member 71 is a linear motor, which is connected to the bottom of the adsorption platform 72 to ensure the stability of the adsorption platform 72 and the accuracy of the moving distance.

[0063] The camera device 8 is arranged in one-to-one correspondence with the detection moving device 7 and the number of the two is the same, so as to take pictures and detect the two groups of strip circuit boards 900 respectively. The camera device 8 is located above the detection moving device 7 at the middle position in the longitudinal direction, and is located between the transfer device 5 and the receiving moving device 6 of the blanking device in the longitudinal direction. The adsorption platform 72 moves back and forth between the transfer device 5 and the blanking device. When the adsorption platform 72 carries a group of strip circuit boards 900 and moves from the transfer device 5 to the blanking device, the group of strip circuit boards 900 passes under the camera device 8, and the camera device 8 takes pictures of the moving group of strip circuit boards 900 for detection.

[0064] like Figure 3 As shown, the camera device 8 includes a camera assembly 81 and a camera drive assembly 82. The camera assembly 81 includes a plurality of cameras arranged horizontally. The camera drive assembly 82 is connected to the camera assembly 81 and is used to drive the camera assembly 81 to rise and fall to adjust the distance between the camera and the strip circuit board 900 for continued focusing.

[0065] like Figure 2 As shown, a dust removal device 9 is also provided on the frame 100. The dust removal device 9 is located between the transfer device 5 and the camera device 8 and above the detection mobile device 7. The dust removal device 9 is used to remove dust from the strip circuit board 900 transported by the detection mobile device 7 before taking pictures.

[0066] The strip circuit board appearance inspection machine may also include a controller, which is electrically connected to the receiving mobile device 3 (6), the whole board device 4, the transfer device 5, the two detection mobile devices 7, the two camera devices 8, the dust removal device 9, and the lifting device 120, etc., to control the operation of each device. In addition, the controller may not be provided, and it may be electrically connected to the user's computer through a data cable, a wireless communication module, etc., and the drive and control software of the strip circuit board appearance inspection machine may be installed in the computer, and the operation may be controlled by the computer, thereby reducing the overall cost. The user may input the width size of the strip circuit board to be inspected into the controller or the computer, and combine it with the horizontal size of the limit frame to determine the center distance of the strip circuit board on the material frame, and then control the adjustment of the receiving manipulator.

[0067] The working process of the strip circuit board appearance inspection machine provided by the utility model is as follows.

[0068] A plurality of strip circuit boards are loaded using a loading device. Multiple strip circuit boards to be inspected are stacked on a material frame 1, and the material frame 1 is placed on a cart 2. The cart 2 is pushed to dock it on one side of the receiving platform 110, and the material frame 1 is transferred from the cart 2 to the receiving platform 110. Driven by the receiving drive assembly 32, the receiving manipulator 31 moves to the top of the material frame 1, and adjusts the center distance of the plurality of receiving manipulator arms 312 to match the center distance of the limit frame on the material frame 1, which can match the center distance of the strip circuit boards. Afterwards, the receiving manipulator 31 absorbs a group of strip circuit boards. During this process, the lifting support arm 124 of the lifting device 120 can drive the support plate 13 of the material frame 1 to move upward, so that the strip circuit board moves upward and approaches the receiving manipulator 31.

[0069] The receiving robot 31 is driven by the receiving driving assembly 32 to move to the top of the board-forming device 4, and adjusts the center distance of the multiple receiving robot arms 312 to the preset center distance, so that a group of strip circuit boards can be aligned with the board-forming positions of the board-forming device 4, and each strip circuit board is placed on each board-forming position. The board-forming device 4 performs board-forming on the group of strip circuit boards.

[0070] Driven by the transfer drive assembly 52, the transfer manipulator 51 moves to the top of the whole board device 4, adsorbs a group of strip circuit boards after the whole board, and moves to the top of the adsorption platform 72 of the detection mobile device 7, and places a group of strip circuit boards on the adsorption platform 72. The adsorption platform 72 drives a group of strip circuit boards to move longitudinally, and after passing through the dust removal device 9, the group of strip circuit boards are photographed by the camera assembly 81 for detection. Then, driven by the adsorption platform 72, the strip circuit boards move to the side of the camera device 8 away from the dust removal device 9, that is, move to the unloading device at the other end of the detection mobile device 7, and stack a group of strip circuit boards on the material frame 1 again through the receiving mobile device 6 of the unloading device. In this process, the lifting support arm of the unloading device can drive the support plate of the material frame 1 to gradually move downward, so that the strip circuit boards move downward for easy stacking. After the strip circuit boards on the material frame 1 are full, they are transferred to the cart 2 and removed by the cart 2.

[0071] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
