[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided with reference to the appendix.

[0044] like Figs. 1 to 8 As shown, this specific embodiment provides a testing platform, which includes a machine base 1. A carrier plate 2 for placing a product 8 is installed on the upper surface of the machine base 1. At least two fixed seats 3 are installed around the periphery of the carrier plate 2. Each fixed seat 3 is provided with a rotating shaft 31. A pressure bar 32 and a main gear 33 are fixed on the rotating shaft 31. The pressure bar 32 can rotate to the position above the carrier plate 2. The pressure bar 32 presses down to fix the product 8 placed in the upper carrier plate 2. A linkage gear 4 is installed in the machine base 1 and is connected to the main gear 33 for transmission, so that when one of the pressure bars 32 rotates to the position above the carrier plate 2, the other pressure bars 32 rotate synchronously to the position above the carrier plate 2 to press down and fix the product 8 placed in the upper carrier plate 2.

[0045] After product 8 is placed on carrier plate 2, when one of the pressure bars 32 is rotated above carrier plate 2 by the operator or power module, the pressure bar 32 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the main gear 33 to rotate, the main gear 33 drives the linkage gear 4 to rotate, and at this time, the linkage gear 4 drives all the other main gears 33 to rotate, so that all the pressure bars 32 rotate synchronously above carrier plate 2 to press down and fix product 8 placed in the upper carrier plate 2. Therefore, compared with conventional workbenches that require the operator or multiple power modules to drive the pressure blocks to move one by one, the present invention improves the operating efficiency and reduces the operating cost.

[0046] In some embodiments, the fixing bases 3 are symmetrically arranged around the periphery of the carrier plate 2; so as to achieve the effect of all the pressure strips 32 working together to more stably press and fix the product 8 placed in the upper carrier plate 2.

[0047] In some embodiments, the linkage gear 4 and the main gear 33 are connected by a connecting gear 41, wherein the number of connecting gears 41 between the main gear 33 and the linkage gear 4 differs from the number of connecting gears 41 between the adjacent main gear 33 and the linkage gear 4 by an odd-even difference.

[0048] When the distance between the main gear 33 and the linkage gear 4 exists, the main gear 33 can be drivenly connected with the linkage gear 4 through the engaging gear 41; when the pressing strip 32 is beside the corner position of the product 8, the adjacent two pressing strips 32 can be driven to rotate in a mirror image manner to open the side of the product 8.

[0049] When the product 8 is taken out from the carrier plate 2 or placed into the carrier plate 2, the product 8 can be avoided by rotating the pressing strip 32 with a shorter stroke.

[0050] In some embodiments, the size of the engaging gear 41 between one of the main gears 33 and the linkage gear 4 is different from the size of the engaging gear 41 between the adjacent main gear 33 and the linkage gear 4, so that there is a speed difference between the adjacent two main gears 33, at this time, all the pressing strips 32 are sequentially and gradually rotated out of the carrier plate 2, thereby stably pressing and fixing the product 8.

[0051] In some embodiments, the machine table 1 is provided with the linkage sliding groove 5, the distance adjusting sliding rail 52 and the distance adjusting lead screw module 53 which are adapted to the number and position of the fixed seat 3, the engaging gear 41 is engaged with the linkage gear 4, the distance adjusting sliding rail 52 slides the linkage rack 51 which is engaged with the engaging gear 41, the distance adjusting sliding rail 52 slides the distance adjusting sliding block seat 54 which is drivingly connected with the distance adjusting lead screw module 53, the distance adjusting sliding block seat 54 is provided with the displacement sliding groove 55 and the displacement cylinder 56, the displacement sliding groove 55 slides the displacement sliding block 57, the fixed seat 3 is installed on the displacement sliding block 57, the main gear 33 is drivingly and closely engaged with the linkage rack 51 by magnetic attraction, and the displacement cylinder 56 is used to push the displacement sliding block 57, so that when the distance adjusting sliding block seat 54 moves, the main gear 33 is separated from the linkage rack 51.

[0052] The displacement cylinder 56 pushes the displacement sliding block 57 to separate the main gear 33 from the linkage rack 51, at this time, the distance adjusting lead screw module 53 pushes the distance adjusting sliding block seat 54 to slide on the distance adjusting sliding rail 52 to drive the fixed seat 3 to move to the adaptive position, after that, the displacement cylinder 56 pushes the displacement sliding block 57 to reset, and the main gear 33 is drivingly and closely engaged with the linkage rack 51 by magnetic attraction, therefore, when the product 8 of different sizes is placed on the carrier plate 2, the transverse position of the pressing strip 32 can be adjusted according to the product 8 of different sizes.

[0053] In some embodiments, the machine table 1 is provided with the swing lead screw module 6 and the swing plate 61 which are adapted to the number and position of the fixed seat 3, the driving end of the swing lead screw module 6 is bearingly connected with the swing plate 61, the bearing connection position of the swing plate 61 is concentric with the engaging gear 41, the linkage sliding groove 5, the distance adjusting sliding rail 52 and the distance adjusting lead screw module 53 are installed on the swing plate 61, and the fixed seat 3 is provided with the infrared sensor for sensing the direction of the pressing strip 32.

[0054] The swing plate 61 is driven to swing by the swing screw module 6, and the fixed seat 3 is driven to swing, so that when the products 8 of different sizes are placed on the carrier plate 2, the longitudinal position of the pressing strip 32 can be adjusted according to the products 8 of different sizes.

[0055] In some embodiments, an inductive sheet 42 is installed on the linkage gear 4, and a photoelectric switch 43 for identifying the position of the inductive sheet 42 is installed on the periphery of the linkage gear 4.

[0056] The rotation stroke of the linkage gear 4 can be sensed, so that it is determined whether all the pressing strips 32 have been pressed to fix the products 8 placed on the upper carrier plate 2.

[0057] In some embodiments, a photoelectric sensor 21 is installed in the carrier plate 2, which is used to identify whether the products 8 are placed in the carrier plate 2 or identify the size of the products 8 placed in the carrier plate 2.

[0058] After the photoelectric sensor 21 identifies that the products 8 have been placed in the carrier plate 2, the power module or the equipment on the workbench that drives the pressing strip 32 to rotate is activated; in addition, when the products 8 of different sizes are placed on the carrier plate 2, the size of the products 8 can be sensed by the photoelectric sensor 21, so that the position of the pressing strip 32 is adjusted adaptively.

[0059] In some embodiments, the transverse and longitudinal edges of the carrier plate 2 are each provided with a limiting strip 22 for limiting and positioning the products 8;

[0060] After the products 8 are placed in the carrier plate 2, the limiting and positioning of the products 8 by the limiting strip 22 can avoid displacement of the products 8 during the process of pressing the products 8 placed in the upper carrier plate 2 by the pressing strip 32.

[0061] In some embodiments, a magnetic seat 7 is installed on the machine table 1, the magnetic seat 7 adsorbs a removable clip base 71, the clip base 71 is installed with a conductive block 72, the conductive block 72 is supported by a spring with an upper clip 73 that can float up and down, and when the upper clip 73 is pressed to be close to the conductive block 72, the conductive block 72 and the upper clip 73 are used to insert the interface of the product 8, at this time, when the upper clip 73 is released, the spring pushes the upper clip 73 to open outward with the conductive block 72 to be fixed in the interface.

[0062] When the products 8 are electronic products 8, the data interface of the products 8 can be conveniently inserted or pulled out from the data interface; when the clip base 71 is idle, the clip base 71 can be placed on the magnetic seat 7 for fixation, so as to avoid the magnetic seat 7 from interfering with other operations on the products 8 placed on the carrier plate 2.

An upper clip 73 that floats up and down is supported on the conductive block 72 by a spring. The conductive block 72 and the upper clip 73 are used to insert into the interface of the product 8.

[0068] At least two fixing seats 3 are installed around the periphery of the carrier plate 2. In this specific embodiment, four fixing seats 3 are installed around the periphery of the carrier plate 2. The fixing seats 3 are symmetrically arranged around the periphery of the carrier plate 2. Each fixing seat 3 is provided with a rotating shaft 31. A pressure strip 32 and a main gear 33 are fixed on the rotating shaft 31. The pressure strip 32 can rotate to the pressure strip 32 above the carrier plate 2. The pressure strip 32 is used to press down and fix the product 8 placed in the upper carrier plate 2. A linkage gear 4 is installed in the machine base 1. The linkage gear 4 and the main gear 33 are connected by meshing connecting gears 41 to achieve transmission. At the same time, the number of connecting gears 41 between two adjacent main gears 33 connected to the linkage gear 4 differs between odd and even numbers. At the same time, the size difference exists between the connecting gears 41 between two adjacent main gears 33 connected to the linkage gear 4. A sensing plate 42 is installed on the linkage gear 4.

[0069] The following is a description of the operation of a test bench as described in this specific embodiment.

[0070] The product 8 is placed in the carrier plate 2, and the limiting strip 22 limits and positions the product 8; when the photoelectric sensor 21 identifies that the product 8 has been placed in the carrier plate 2, one of the pressing strips 32 is rotated to above the carrier plate 2 by the power module or the operator; during the rotation of one of the pressing strips 32 to above the carrier plate 2, the pressing strip 32 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the main gear 33 to rotate, and the main gear 33 drives the linkage gear 4 to rotate; at this time, the linkage gear 4 drives all the remaining main gears 33 to rotate, so that all the pressing strips 32 are synchronously rotated to above the carrier plate 2 to press and fix the product 8 placed in the carrier plate 2; at this time, the linkage gear 4 has moved the sensing sheet 42 to the photoelectric switch 43, and the photoelectric switch 43 can send a command to activate the processing test machine to test the product 8 on the carrier plate 2 after sensing the sensing sheet 42.

[0071] If the product 8 placed in the carrier plate 2 is an electronic product 8 with a data interface, the upper clamp 73 is pressed at this time, and the upper clamp 73 is attached to the conductive block 72; thereafter, the conductive block 72 and the upper clamp 73 are used to insert the interface of the product 8; thereafter, the upper clamp 73 is released, and the spring pushes the upper clamp 73 and the conductive block 72 to expand outward to be fixed in the interface, and at the same time, the conductive block 72 is tightly attached to the conductive feeler in the interface by the outward tension, so as to realize the power-on test of the electronic product 8.

[0077] The machine table 1 is provided with a swing wire rod module 6 and a swing plate 61 which are connected with the fixed seat 3. The driving end of the swing wire rod module 6 is connected with the swing plate 61. The swing plate 61 is concentric with the linkage gear 41. The swing plate 61 is provided with a linkage sliding groove 5, a distance adjusting sliding rail 52 and a distance adjusting wire rod module 53.

When the upper clip 73 is released, the spring pushes the upper clip 73 to be opened to be fixed in the data interface.

[0079] The following is the working principle of the test workbench.

[0080] When the product 8 is placed on the carrier plate 2, the photoelectric sensor 21 identifies the size of the product 8 placed in the carrier plate 2, the displacement cylinder 56 pushes the displacement slider 57 to separate the main gear 33 from the linkage rack 51, at this time, the distance adjusting lead screw module 53 pushes the distance adjusting slider seat 54 to slide on the distance adjusting slide rail 52 to drive the fixed seat 3 to move to the adaptive position, so as to adjust the horizontal position of the pressing strip 32, then the displacement cylinder 56 pushes the displacement slider 57 to reset, and the main gear 33 is actively attached to and engaged with the linkage rack 51 by magnetic attraction; if it is necessary to adjust the vertical position of the pressing strip 32, the displacement cylinder 56 pushes the displacement slider 57 to separate the main gear 33 from the linkage rack 51, at this time, the swing lead screw module 6 drives the swing plate 61 to swing to drive the fixed seat 3 to swing, and at the same time, the distance adjusting lead screw module 53 pushes the distance adjusting slider seat 54 to slide on the distance adjusting slide rail 52, so as to adjust the vertical position of the pressing strip 32; because the orientation of the pressing strip 32 changes after the fixed seat 3 is adjusted, it is necessary to adjust the orientation of the pressing strip 32, when the orientation of a pressing strip 32 is adjusted, all the displacement cylinders 56 on the fixed seats 3 except the displacement cylinder 56 on the fixed seat 3 where the pressing strip 32 is located push the displacement sliders 57 to separate the main gears 33 from the linkage racks 51, then the pressing strip 32 whose orientation needs to be adjusted is driven to rotate by the power module or the operator, at this time, the infrared sensor senses the orientation of the pressing strip 32 during the adjustment, after the orientation of the pressing strip 32 is adjusted, all the displacement cylinders 56 push the displacement sliders 57 to reset, and all the main gears 33 are actively attached to and engaged with the linkage racks 51 by magnetic attraction.

[0081] After the position of the pressing strip 32 is adjusted, one of the pressing strips 32 is driven to rotate above the carrier plate 2 by the power module or the operator; during the rotation of one of the pressing strips 32 above the carrier plate 2, the pressing strip 32 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the main gear 33 to rotate, and the main gear 33 drives the linkage gear 4 to rotate, at this time, the linkage gear 4 drives all the main gears 33 to rotate, so that all the pressing strips 32 are synchronously rotated above the carrier plate 2 to press and fix the product 8 placed in the carrier plate 2, at this time, the linkage gear 4 has moved the sensing sheet 42 to the photoelectric switch 43, after the photoelectric switch 43 senses the sensing sheet 42, it can send a command to activate the processing test machine to test the product 8 on the carrier plate 2.

[0082] If the product 8 placed in the carrier plate 2 is an electronic product 8 with a data interface, the upper clamp 73 is pressed, and the upper clamp 73 is in contact with the conductive block 72. Then, the conductive block 72 and the upper clamp 73 are used to insert into the interface of the product 8. Then, the pressing on the upper clamp 73 is released, and the spring pushes the upper clamp 73 and the conductive block 72 to open outward to be fixed in the interface. At the same time, the conductive block 72 is tightly attached to the conductive contact in the interface by the outward tension, so that the electronic product 8 is powered on for testing.
