[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0030] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides an alternating feeding fixture, comprising:
[0031] Base 1, base 1 is set horizontally;
[0032] Guide plate 2 is vertically connected to base 1. A guide groove 21 is provided on the side of guide plate 2. The guide groove 21 includes two horizontal sections 211 extending along the length direction of base 1 and a V-shaped section 212 located between the two horizontal sections 211.
[0033] Rodless cylinder 3 is connected to the base 1 along its length.
[0034] Synchronous belt assembly 4 is connected to the base 1 along its length;
[0035] The first material rack 5 includes a first material carrier plate 51, which is slidably connected to the base 1 along its length and is connected to the synchronous belt of the synchronous belt assembly 4.
[0036] The second material rack 6 includes a sliding seat 61 and a second material carrier plate 62. The sliding seat 61 is slidably connected to the base 1 along its length. The sliding seat 61 is connected to the rodless cylinder 3 and the synchronous belt respectively. Multiple sliding rods 63 that slide vertically are slidably arranged on the sliding seat 61. The end of each sliding rod 63 away from the sliding seat 61 is connected to the second material carrier plate 62. A connecting arm 64 is connected to the second material carrier plate 62. A guide member 65 that is rotatably connected to the guide groove 21 is rotatably arranged on the connecting arm 64.
[0037] Specifically, the height of the first loading plate 51 is higher than the height of the second loading plate 62, and the first loading plate 51 and the second loading plate 62 are respectively connected to the upper and lower sections of the synchronous belt 41. When the rodless cylinder 3 drives the sliding seat 61 to move, the synchronous belt 41 connected to the sliding seat 61 is driven. The rotating synchronous belt 41 drives the first loading plate 51 connected to it to move. Since the sliding seat 61 and the first loading plate 51 are respectively connected to the two sections of the synchronous belt 41 with opposite directions of movement, the first loading plate 51 and the second loading plate 62 move synchronously towards each other. When the second loading plate 62 moves to a position close to the first loading plate 51, the guide member 65 connected to the second loading plate 62 enters the V-shaped section 212 from the horizontal section 211 of the guide groove 21, causing the second loading plate 62 to perform a movement of first descending and then rising. The second loading plate 62 passes under the first loading plate 51 to avoid it, thereby realizing the synchronous loading and unloading, effectively shortening the test cycle and improving the test efficiency.
[0038] This utility model discloses an alternating feeding fixture, which is equipped with two material racks and a drive mechanism to drive the two material racks to move synchronously towards each other. A guide structure is also provided, through a guide groove 21 with a V-shaped section 212, which, in conjunction with the guide structure, allows one material rack to descend and then rise during movement, achieving avoidance during the synchronous movement of the two material racks. Ultimately, it enables synchronous loading and unloading, thereby effectively shortening the testing cycle and improving product testing efficiency. The entire fixture has a simple structure, is easy to install and maintain, and reduces the use of cylinders, lowering the risk of device failure due to cylinder leakage during use.
[0039] Further, the base 1 includes a bottom plate 11, side plates 12, and intermediate plates 13. The bottom plate 11 is horizontally arranged, and two parallel side plates 12 are vertically connected to the bottom plate 11. Two intermediate plates 13, located between and parallel to the two side plates 12, are also vertically connected to the bottom plate 11. Specifically, the two side plates 12 are symmetrically arranged on the top of the bottom plate 11, and the rodless cylinder 3 and the synchronous belt assembly 4 are respectively arranged on opposite sides of the two side plates 12. The two intermediate plates 13 are vertically connected to the top of the bottom plate 11 and located between the two side plates 12, with the height of the intermediate plates 13 lower than the height of the side plates 12. The guide plate 2 is vertically connected to the bottom plate 11 and located between the two intermediate plates 13. One end of the connecting arm 64 is connected to the bottom of the second loading plate 62, and the other end extends through the sliding seat 61 to one side of the guide plate 2 and is connected to the guide groove 21 via the guide member 65.
[0040] Furthermore, each of the two side plates 12, away from the bottom plate 11, is connected to a first slide rail extending along its length, and the two ends of the first material carrier plate 51 are slidably connected to the two first slide rails respectively through a first slider.
[0041] Furthermore, each of the two intermediate plates 13 is connected to a second slide rail extending along its length at the end away from the base plate 11, and the sliding seat 61 is slidably connected to the two second slide rails respectively through the second slider.
[0042] Furthermore, the rodless cylinder 3 can also be replaced by a linear drive structure such as a linear motor, and is not limited to the rodless cylinder 3.
[0043] Furthermore, the synchronous belt assembly 4 includes a synchronous belt 41 and two synchronous pulleys 42. The two synchronous pulleys 42 are rotatably connected to one side of any side plate 12, and are connected by the synchronous belt 41. Specifically, two connecting shafts are symmetrically arranged on the side of any side plate 12, and the two synchronous pulleys 42 are rotatably connected to the two connecting shafts respectively, and are connected by the synchronous belt 41. More preferably, a mounting seat with an oblong hole can be provided on the side plate 12. The mounting seat is connected to the side plate 12 at the oblong hole by fasteners. A connecting shaft is installed on the mounting seat, and the position of the mounting seat and the synchronous pulleys 42 on it can be finely adjusted through the oblong hole of the mounting seat, thereby ensuring that the synchronous belt 41 connected between the two synchronous pulleys 42 can be tensioned.
[0044] Furthermore, the sliding seat 61 has multiple through holes vertically opened, and a linear bearing is coaxially arranged in each through hole. Each sliding rod 63 is slidably connected to a linear bearing.
[0045] Furthermore, a limiting element is provided at the end of the slide bar 63 away from the second material carrier plate 62.
[0046] Furthermore, the system includes a clamping assembly comprising a base plate and clamping plates. The base plate is connected to the first carrier plate 51 or the sliding seat 61. The clamping plates are connected parallel to one side of the base plate by fasteners and clamp the timing belt 41 between the base plate and the base plate. More preferably, the side of the clamping plates facing the base plate has multiple protrusions, which increase the friction between the clamping plates and the timing belt 41, ensuring that the timing belt 41 is clamped securely.
[0047] Furthermore, multiple positioning pins are respectively provided on the first material carrier plate 51 and the second material carrier plate 62, and the positioning pins are used to fix the product to be tested.
[0048] Furthermore, the guide element 65 can be a bearing.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
