At this time, the pitch-adjusting screw module pushes the pitch-adjusting slider seat to slide on the pitch-adjusting slide rail to drive the fixed seat to move to the matching position. Thereafter, the shift cylinder pushes the shift slider to reset, and the main gear actively adheres to and engages with the linkage rack through magnetic attraction. Therefore, when placing products of different sizes on the carrier plate, the lateral position of the pressure strip can be adjusted according to the products of different sizes.

[0014] In some embodiments, both the horizontal and vertical sides of the carrier plate are provided with limiting strips for limiting and positioning the product; According to the technical solution, after the product is placed on the carrier, the product is limited and positioned by the limiting strip, thereby preventing the product from shifting when the pressing strip presses down and fixes the product placed on the upper carrier.

[0015] In some embodiments, a magnetic seat is installed on the machine platform, and a removable clip base is adsorbed on the magnetic seat, and a conductive block is installed on the clip base. An upper clip that floats up and down is supported by a spring on the conductive block. When the upper clip is pressed down to be close to the conductive block, the conductive block and the upper clip are used to insert into the interface of the product.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is an enumerated description with reference to the appended drawings.

[0020] like Figures 1 to 8As shown, this specific embodiment provides a test bench, which includes a machine 1, a carrier plate 2 for placing products 8 is installed on the upper surface of the machine 1, at least two fixing seats 3 are installed around the carrier plate 2, each fixing seat 3 is provided with a rotating shaft 31, and 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, and 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 connected to the main gear 33 is installed in the machine 1, so that when one of the pressure strips 32 rotates to the top of the carrier plate 2, the remaining pressure strips 32 rotate synchronously to the top of the carrier plate 2 to press down and fix the product 8 placed in the upper carrier plate 2.

[0021] After the product 8 is placed on the carrier 2, when one of the pressure strips 32 is driven by the operator or the power module to rotate above the carrier 2, the pressure 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 pressure strips 32 are synchronously rotated to above the carrier 2 to press down and fix the product 8 placed in the upper carrier 2; therefore, compared with the conventional workbench that requires the operator or the use of multiple power modules to drive the pressing blocks to move one by one, the present invention improves the operating efficiency and reduces the operating cost.

[0022] In some embodiments, the fixing seats 3 are symmetrically arranged around the carrier plate 2 to achieve a cooperative effect through all the pressure strips 32, so as to more stably press down and fix the product 8 placed in the upper carrier plate 2.

[0023] In some embodiments, the linkage gear 4 and the main gear 33 are connected to each other through connecting gears 41, and the number of connecting gears 41 between one main gear 33 and the linkage gear 4 is different from the number of connecting gears 41 between its adjacent main gear 33 and the linkage gear 4.

[0024] When there is a distance between the main gear 33 and the linkage gear 4, the main gear 33 can be connected to the linkage gear 4 through the connecting gear 41; when the pressure strip 32 is located next to the corner of the product 8, the door can be opened on the side of the product 8 in a mirror-image manner by driving the two adjacent pressure strips 32.

[0025] When the product 8 is taken out of the carrier plate 2 or put into the carrier plate 2 , the product 8 can be avoided by rotating the pressing strip 32 with a shorter stroke.

[0026] In some embodiments, there is a size difference between the connecting gear 41 between one main gear 33 and the linkage gear 4 and the connecting gear 41 between its adjacent main gear 33 and the linkage gear 4, so that there is a speed difference between two adjacent main gears 33. At this time, all the pressure strips 32 also rotate out from above the carrier plate 2 in an orderly and gradual manner, thereby pressing down and fixing the product 8 smoothly.

[0027] In some embodiments, the machine 1 is equipped with a linkage slide 5, a pitch-adjusting slide rail 52 and a pitch-adjusting screw module 53 that are adapted to the number and position of the fixed seat 3. The connecting gear 41 is meshed with the linkage gear 4. A linkage rack 51 meshed with the connecting gear 41 slides in the pitch-adjusting slide rail 52. A pitch-adjusting slider seat 54 that is transmission-connected to the pitch-adjusting screw module 53 slides on the pitch-adjusting slide rail 52. A shifting slide 55 and a shifting cylinder 56 are installed on the pitch-adjusting slider seat 54. A shifting slider 57 slides on the shifting slide 55. The fixed seat 3 is installed on the shifting slider 57. The main gear 33 actively adheres to and meshes with the linkage rack 51 by magnetic attraction. The shifting cylinder 56 is used to push the shifting slider 57 so that when the pitch-adjusting slider seat 54 moves, the main gear 33 is separated from the linkage rack 51.

[0028] The shift cylinder 56 pushes the shift slider 57 to separate the main gear 33 from the linkage rack 51. At this time, the pitch-adjusting screw module 53 pushes the pitch-adjusting slider seat 54 to slide on the pitch-adjusting slide rail 52 to drive the fixed seat 3 to move to the matching position. Thereafter, the shift cylinder 56 pushes the shift slider 57 to reset, and the main gear 33 actively adheres to and engages with the linkage rack 51 by magnetic attraction. Therefore, when products 8 of different sizes are placed on the carrier plate 2, the lateral position of the pressure strip 32 can be adjusted according to the products 8 of different sizes.

[0029] In some embodiments, the machine 1 is bearing-connected with a rocking screw module 6 and a rocking plate 61 whose number and position are adapted to the fixed seat 3. The driving end of the rocking screw module 6 is bearing-connected with the rocking plate 61. The bearing connection position of the rocking plate 61 is concentric with the connecting gear 41. The linkage slide groove 5, the distance adjusting slide rail 52 and the distance adjusting screw module 53 are installed on the rocking plate 61. An infrared sensor for sensing the direction of the pressure strip 32 is installed on the fixed seat 3.

[0030] The rocking plate 61 is driven to rock by the rocking screw module 6 to drive the fixing seat 3 to rock, so that when products 8 of different sizes are placed on the carrier plate 2, the longitudinal position of the pressure strip 32 can be adjusted according to the products 8 of different sizes.

[0031] In some embodiments, a sensing sheet 42 is installed on the linkage gear 4 , and a photoelectric switch 43 for identifying the position of the sensing sheet 42 is installed around the linkage gear 4 .

[0032] By sensing the rotation stroke of the linkage gear 4 , it is possible to determine whether all the pressing strips 32 have pressed down and fixed the product 8 placed in the upper loading plate 2 .

[0033] In some embodiments, a photoelectric sensor 21 is installed in the carrier board 2 , and the photoelectric sensor 21 is used to identify whether the product 8 is placed in the carrier board 2 or to identify the size of the product 8 placed in the carrier board 2 .

[0034] The power module or the equipment on the workbench that drives the pressing strip 32 to rotate is activated only after the photoelectric sensor 21 recognizes that the product 8 has been placed in the carrier 2; in addition, when products 8 of different sizes are placed on the carrier 2, the photoelectric sensor 21 can sense the size of the product 8, thereby adaptively adjusting the position of the pressing strip 32.

[0035] In some embodiments, both the horizontal and vertical sides of the carrier plate 2 are provided with limiting strips 22 for limiting and positioning the product 8; After the product 8 is placed on the carrier plate 2 , the limiting strip 22 is used to limit and position the product 8 , thereby preventing the product 8 from shifting when the pressing strip 32 is used to press down and fix the product 8 placed on the upper carrier plate 2 .

[0036] In some embodiments, a magnetic seat 7 is installed on the machine 1, and a removable clip base 71 is adsorbed on the magnetic seat 7. A conductive block 72 is installed on the clip base 71. An upper clip 73 floating up and down is supported by a spring on the conductive block 72. When the upper clip 73 is pressed down to fit the conductive block 72, the conductive block 72 and the upper clip 73 are used to insert into the interface of the product 8. At this time, when the upper clip 73 is pressed down by releasing the pressure, the spring pushes the upper clip 73 and the conductive block 72 to open outward so as to be fixed in the interface.

[0037] When the product 8 is an electronic product 8, it can be conveniently inserted into or unplugged from the data interface of the product 8; when the clip base 71 is idle, the clip base 71 can be placed on the magnetic base 7 for fixation, thereby preventing the magnetic base 7 from interfering with other operations on the product 8 placed on the carrier 2.

[0038] In order to further illustrate the test bench described in this specific implementation manner, the following embodiments are listed.

[0039] Example 1 like Figures 1 to 6 As shown, this embodiment provides a test bench, which includes a machine platform 1, and a carrier plate 2, a magnetic seat 7 and a linkage gear 4 are installed on the upper surface of the machine platform 1.

[0040] The carrier plate 2 is used to place the product 8. The horizontal and vertical edges of the carrier plate 2 are both provided with limit strips 22 for limiting and positioning the product 8. A photoelectric sensor 21 is installed inside the carrier plate 2 for identifying whether the product 8 is placed inside.

[0041] A clip base 71 is placed on the magnetic seat 7, and the magnetic seat 7 can absorb the clip base 71. A conductive block 72 is installed on the clip base 71. An upper clip 73 floating up and down is supported by a spring on the conductive block 72. The conductive block 72 and the upper clip 73 are used to insert the product 8 interface.

[0042] At least two fixing seats 3 are installed around the carrier plate 2, and in this specific embodiment, four fixing seats 3 are installed around the carrier plate 2, and the fixing seats 3 are symmetrically arranged around the carrier plate 2. Each fixing seat 3 is provided with a rotating shaft 31, and 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, and the pressure strip 32 is pressed down to fix the product 8 placed in the upper carrier plate 2, and a linkage gear 4 is installed in the machine 1. The linkage gear 4 and the main gear 33 are connected by a meshing connecting gear 41 to achieve transmission connection; at the same time, there is an odd and even number difference between the two adjacent main gears 33 connected to the linkage gear 4; at the same time, there is a size difference between the two adjacent main gears 33 connected to the linkage gear 4 and the connecting gear 41 between the two adjacent main gears 33 and the linkage gear 4. A sensor sheet 42 is installed on the linkage gear 4, and a photoelectric switch 43 for identifying the position of the sensor sheet 42 is installed around the linkage gear 4.

[0043] The following is a working description of a test bench described in this specific implementation method.

[0044] During the process of placing the product 8 on the carrier 2, the limit strip 22 limits and positions the product 8; when the photoelectric sensor 21 recognizes that the product 8 has been placed in the carrier 2, one of the pressure strips 32 can be driven by the power module or the operator to rotate to the top of the carrier 2; during the process of one of the pressure strips 32 rotating to the top of the carrier 2, the pressure 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 pressure strips 32 rotate synchronously to the top of the carrier 2 to press down and fix the product 8 placed in the upper carrier 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 issue a command to activate the processing and testing unit to test the product 8 on the carrier 2.

[0045] If the product 8 placed in the carrier 2 is an electronic product 8 with a data interface, the upper clip 73 is pressed, and at this time, the upper clip 73 is in contact with the conductive block 72; thereafter, the conductive block 72 and the upper clip 73 are used to be inserted into the interface of the product 8; thereafter, the pressure on the upper clip 73 is released, and at this time, the spring pushes the upper clip 73 and the conductive block 72 to open outward to achieve fixation in the interface. At the same time, the conductive block 72 is pressed against the conductive feeler in the interface through external tension, thereby realizing power-on testing of the electronic product 8.

[0046] Example 2 like Figures 1 to 4 As shown in FIGS. 7 and 8 , this embodiment provides a test bench, which includes a machine platform 1 , and a carrier board 2 is mounted on the upper surface of the machine platform 1 .

[0047] The carrier board 2 is used to place the product 8. A photoelectric sensor 21 is installed in the carrier board 2. The photoelectric sensor 21 is used to identify whether the product 8 is placed in the carrier board 2 and to identify the size of the product 8 placed in the carrier board 2. The photoelectric sensor 21 can be an infrared distance sensor horizontally set on the carrier board 2.

[0048] The outer periphery of the four corners of the carrier plate 2 is respectively provided with a fixing seat 3, each fixing seat 3 is provided with a rotating shaft 31, and a pressure strip 32 and a main gear 33 are fixed on the rotating shaft 31. The pressure strip 32 can be rotated to the pressure strip 32 above the carrier plate 2. The pressure strip 32 is pressed down to fix the product 8 placed in the upper carrier plate 2. An infrared sensor for sensing the direction of the pressure strip 32 is installed on the fixing seat 3.

[0049] A linkage gear 4 is installed in the machine 1, and a sensor sheet 42 is installed on the linkage gear 4. A photoelectric switch 43 for identifying the position of the sensor sheet 42 is installed around the linkage gear 4. Each main gear 33 and the linkage gear 4 are connected to each other through a connecting gear 41. The number of connecting gears 41 between one main gear 33 and the linkage gear 4 is different from the number of connecting gears 41 between its adjacent main gear 33 and the linkage gear 4. The size of the connecting gear 41 between one main gear 33 and the linkage gear 4 is different from the size of the connecting gear 41 between its adjacent main gear 33 and the linkage gear 4.

[0050] The machine 1 is bearing-connected with a rocking screw module 6 and a rocking plate 61 whose number and position match the fixed seat 3 . The driving end of the rocking screw module 6 is bearing-connected with the rocking plate 61 . The bearing connection position of the rocking plate 61 is concentric with the connecting gear 41 . A linkage slide 5, a pitch-adjusting slide rail 52 and a pitch-adjusting screw module 53 are installed on the rocking plate 61. The connecting gear 41 is meshed with the linkage gear 4. A linkage rack 51 meshed with the connecting gear 41 slides in the pitch-adjusting slide rail 52. A pitch-adjusting slider seat 54 that is transmission-connected to the pitch-adjusting screw module 53 slides on the pitch-adjusting slide rail 52. A shift slide 55 and a shift cylinder 56 are installed on the pitch-adjusting slider seat 54. A shift slider 57 slides on the shift slide 55. The fixed seat 3 is installed on the shift slider 57. The main gear 33 actively adheres to and meshes with the linkage rack 51 by magnetic attraction. The shift cylinder 56 is used to push the shift slider 57 so that when the pitch-adjusting slider seat 54 moves, the main gear 33 is separated from the linkage rack 51.

[0051] When the product 8 is an electronic device with a data interface, a magnetic seat 7 is installed on the machine 1. The magnetic seat 7 absorbs a removable clip base 71. A conductive block 72 is installed on the clip base 71. An upper clip 73 floating up and down is supported by a spring on the conductive block 72. When the upper clip 73 is pressed down to fit the conductive block 72, the conductive block 72 and the upper clip 73 are used to insert the data interface of the product 8. At this time, when the upper clip 73 is pressed down by releasing the pressure, the spring pushes the upper clip 73 and the conductive block 72 to open outward so as to be fixed in the data interface.

[0052] The following is a working description of a test bench described in this specific implementation method.

[0053] After the product 8 is placed on the carrier 2, when the photoelectric sensor 21 identifies the size of the product 8 placed on the carrier 2, the shift cylinder 56 pushes the shift slider 57 to separate the main gear 33 from the linkage rack 51. At this time, the pitch-adjusting screw module 53 pushes the pitch-adjusting slider seat 54 to slide on the pitch-adjusting slide rail 52 to drive the fixed seat 3 to move to the matching position, thereby adjusting the lateral position of the pressure strip 32. Thereafter, the shift cylinder 56 pushes the shift slider 57 to reset, and the main gear 33 actively adheres to and meshes with the linkage rack 51 by magnetic attraction; if the longitudinal position of the pressure strip 32 needs to be adjusted, the shift cylinder 56 pushes the shift slider 57 to separate the main gear 33 from the linkage rack 51. At this time, the swing screw module 6 drives the swing plate 61 to swing and drives the fixed seat 3 to swing. At the same time, the pitch-adjusting screw module 53 pushes the pitch-adjusting slider seat 54 to adjust the distance. The slide rail 52 slides on the adjustment bar 32 to adjust the longitudinal position of the pressure bar 32; since the orientation of the pressure bar 32 changes after the fixed seat 3 adjusts its position, it is necessary to adjust the orientation of the pressure bar 32. When the orientation of a certain pressure bar 32 is adjusted, except for the shift cylinder 56 on the fixed seat 3 where the pressure bar 32 is located, all other fixed shift cylinders 56 push the shift slider 57 to separate these main gears 33 from the linkage rack 51. Thereafter, the pressure bar 32 whose orientation needs to be adjusted can be adjusted to rotate by the power module or the operator. At this time, the infrared sensor senses the orientation of the pressure bar 32 during the adjustment process. After the orientation of the pressure bar 32 is adjusted, all shift cylinders 56 push the shift slider 57 to reset, and all main gears 33 actively adhere to and mesh with the linkage rack 51 through magnetic attraction.

[0054] After completing the adjustment of the position of the pressure strips 32, one of the pressure strips 32 can be driven to rotate above the carrier plate 2 through the power module or the operator; during the process of one of the pressure strips 32 rotating to above the carrier plate 2, the pressure 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 pressure strips 32 rotate synchronously to above the carrier plate 2 to press down and fix the product 8 placed in the upper carrier plate 2. At this time, the linkage gear 4 has moved the sensor sheet 42 to the photoelectric switch 43. After the photoelectric switch 43 senses the sensor sheet 42, it can issue a command to activate the processing and testing unit to test the product 8 on the carrier plate 2.

[0055] If the product 8 placed in the carrier 2 is an electronic product 8 with a data interface, the upper clip 73 is pressed, and at this time, the upper clip 73 is in contact with the conductive block 72; thereafter, the conductive block 72 and the upper clip 73 are used to be inserted into the interface of the product 8; thereafter, the pressure on the upper clip 73 is released, and at this time, the spring pushes the upper clip 73 and the conductive block 72 to open outward to achieve fixation in the interface. At the same time, the conductive block 72 is pressed against the conductive feeler in the interface through external tension, thereby realizing power-on testing of the electronic product 8.
