Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0027] like Figure 1 , a product flip test fixture, comprising a support frame 1, a flip drive slide 3, a flip drive connecting rod 4, a flip frame 8 and a driving device 11;

[0028] The flip driving slide 3 is slidably arranged on the support frame 1, and the flip driving slide 3 is connected to the driving device 11 for driving the flip driving slide 3 to slide, and the flip driving slide 3 is rotatably connected to one end of the flip driving connecting rod 4, and the other end of the flip driving connecting rod 4 is rotatably connected to the bottom of the flip frame 8, and the flip frame 8 is located above the support frame 1, and the flip frame 8 is rotatably connected to the support frame 1 on both sides;

[0029] The turnover frame 8 is provided with a trough for placing products.

[0030] A plurality of anti-drop pressing wheel mechanisms 6 are disposed on both sides of the flip frame 8 , and the anti-drop pressing wheel mechanisms 6 on both sides are symmetrically disposed; the anti-drop pressing wheel mechanisms 6 are used to press the product before it falls.

[0031] Specifically, the flip frame 8 is located directly above one end of the support frame 1, and the overall length of the flip frame 8 is less than the length of the support frame 1. Two flip driving links 4 can be provided, and the two flip driving links 4 are located on both sides of the bottom of the flip frame 8. The flip driving slide 3 is driven to slide linearly by the driving device 11, so that the flip driving slide 3 drives the flip driving link 4 to deflect, and the flip driving link 4 deflects and drives the flip frame 8 to rotate. Figure 1 , which is the initial state of the utility model, at this time the turning frame 8 is placed horizontally, in this state, the product can be placed in the groove body of the turning frame 8, and then the driving device 11 is started, such as Figure 2 , the turning frame 8 slowly rotates until the product falls off the turning frame 8 to complete the test. In order to prevent the product from falling prematurely during the turning process of the turning frame 8, an anti-dropping pressing wheel mechanism 6 is designed. When the turning angle of the turning frame 8 is greater than 90°, the anti-dropping pressing wheel mechanism 6 releases the product to make the product fall normally.

[0032] The utility model drives the flip driving slide 3 to slide on the support frame 1 through the driving device 11. The sliding of the flip driving slide 3 drives the flip driving connecting rod 4 to move. Since one end of the flip driving connecting rod 4 is rotatably connected to the flip driving slide 3 and the other end is rotatably connected to the bottom of the flip frame 8, the movement of the flip driving connecting rod 4 will drive the flip frame 8 to rotate around the rotation connection point between it and the support frame 1. The flip frame 8 is provided with a trough for placing products. When the flip frame 8 rotates, the products in the trough will flip accordingly until the products fall off the flip frame 8, thereby finally realizing the flip test of the products.

[0033] The utility model realizes the automated flip and drop test of the product through the drive of the driving device 11, reduces the labor intensity of manual operation, and improves the test efficiency. The flip and drop test can be carried out in a specific area. The rotation connection design between the flip frame 8 and the support frame 1 ensures the stability of the flipping process, avoids the shaking or falling of the product during the flipping process, and has a strong supporting force. The trough body provided on the flip frame 8 can be customized according to the shape and size of different products, so that the tooling is suitable for flip tests of various products. The entire flipping process is controlled by the driving device 11, which is simple to operate and easy to master. The structural design of the support frame 1, the flip drive slide 3, the flip drive connecting rod 4 and the flip frame 8 is compact, which saves space and is easy to arrange and use.

[0034] It should be noted that the maximum rotation angle of the turning frame 8 is greater than 90°. For example, the maximum rotation angle of the turning frame 8 is 100°. At this angle, the product can tilt and fall.

[0036] Furthermore, the driving device 11 is installed at one end of the support frame 1, the output end of the driving device 11 is fixedly connected to one end of the trapezoidal screw rod 10, and the other end of the trapezoidal screw rod 10 is rotatably connected to the support frame 1, and the trapezoidal screw rod 10 passes through the flip driving slide 3 and is threadedly connected to the flip driving slide 3.

[0037] A threaded through hole is provided on the flip driving slide 3 and matches with the thread on the trapezoidal lead screw 10. The movement of the flip driving slide 3 is achieved by the rotation of the trapezoidal lead screw 10.

[0038] Furthermore, two linear guide rails 9 are installed on the support frame 1 , and the flip driving slide 3 is slidably disposed on the two linear guide rails 9 .

[0039] Two linear guide rails 9 are arranged in parallel and distributed on both sides of the flip driving slide 3. The linear guide rails 9 form a constraint structure for the flip driving slide 3 to prevent it from rotating, so that the trapezoidal lead screw 10 can drive the flip driving slide 3 to move.

[0040] Furthermore, the support frame 1 includes a bottom portion and two side portions; the two side portions are fixedly connected to both sides of the bottom portion, the flipping drive slide 3 is located between the two side portions, and the tops of the two side portions are fixedly connected with support bearing seats 7, and the two support bearing seats 7 are rotatably connected to both sides of the flip frame 8 respectively.

[0041] The side standing part lifts up the turning frame 8 so that the turning frame 8 is at a certain height from the supporting frame 1 , which is convenient for the turning frame 8 and the turning driving connecting rod 4 to rotate.

[0042] Furthermore, an artificial platform is arranged on the side stand, and an escalator is arranged on one side of the artificial platform. An operator can climb onto the artificial platform via the escalator to perform maintenance work.

[0043] Furthermore, the turnover frame 8 is a frame structure with a hollow part. The turnover frame 8 is a cubic structure as a whole, which includes 5 faces, and the 5 faces can be made by a frame structure.

[0045] Furthermore, one end of the pressing arm 602 away from the connecting rod 603 is rotatably connected to a pressing wheel 601, and the pressing wheel 601 is located above the trough body. The pressing wheels 601 on both sides of the flip frame 8 are used to press the product.

[0046] The connecting rod 603 is arranged vertically, and the pressing arm 602 is perpendicular to the rotation direction of the flip frame 8. In specific implementation, the connecting rod 603 is driven to move up and down by the linear drive device 5, the pressing arm 602 is rotated, and the connecting rod 603 and the linear drive device 5 form corresponding deflections, thereby realizing the function of the pressing wheel 601 pressing the product. The linear drive device 5 is a prior art, such as an electric cylinder, a pneumatic cylinder, etc. The connecting rod 603 can be a separate rod body or an output rod body of the linear drive device 5. When the linear drive device 5 drives the connecting rod 603 to move downward, multiple pressing arms 602 are unfolded and leave the coverage range of the trough body, which can avoid interfering with the product falling.

[0047] It should be noted that the multiple pressing arms 602 are not deployed until the turning frame 8 turns over to a threshold angle, for example, the threshold angle is 90°, and the multiple pressing arms 602 are not deployed until the turning frame 8 turns over to 90°, which can be controlled by a PLC program. The advantage of this design is that it can prevent the product from falling prematurely, making the entire test fixture more stable and reliable.
