Description

Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and in particular relates to a panel testing needle bed. Background Art

[0002] 1. In a conventional test bed of needles, the product or carrier is mainly placed above or below the probe module by vertical movement, and then the power module is used to drive the pressure plate to press the product or carrier vertically, so that the probe module and the product are in contact and energized, so as to perform the test. Therefore, when loading and unloading, it is necessary to use the power module to drive the pressure plate away from the product placement position to reserve enough space to place or remove the product, which results in the test bed of needles occupying a large space and a large volume.

[0003] 2. In addition, panelization means to add side strips to PCB units when necessary to meet PCB assembly requirements, and connect one or more PCB graphics and side strips in a certain way to form a larger, regular PCB shape. Since panelization is composed of multiple small board components, there are multiple stations that need to be inspected on the panel. Therefore, if the conventional SMT one-time full inspection method is adopted, the following technical problems will occur:

[0004] (1) In the test bed, the number of probe modules and testing instruments corresponding to the stations that need to be tested on the panel will also increase exponentially according to the number of panel stations, resulting in high testing costs for the panel;

[0005] (2) Since the gap between the workstations inside the panel is small, it is not conducive to the activity of the probe and the lead-out line, and it is easy to cause interference with the adjacent inspection station or inspection device;

[0006] (3) It is impossible to conduct selective sampling or full inspection of the panels. Utility Model Content

[0007] The utility model aims to provide a panel test needle bed to solve the technical defects described in the background technology.

[0008] The described panel test needle bed includes a press bed, which is provided with a floating plate and a downward pressing power module. A plate placing part is provided on the floating plate, and positioning bars are installed on three sides of the plate placing part. A carrier plate is placed in the plate placing part, and the carrier plate can slide out or slide in from the side of the plate placing part where no positioning bar is provided. The carrier plate is provided with a product slot for placing the panel. A probe module is fixedly installed under the floating plate. When the floating plate descends, the probe module can pass through the floating plate and the carrier plate into the product slot to contact the panel and be energized. The downward pressing power module drives the press plate that presses down on the carrier plate and pushes the floating plate down.

[0009] According to the technical solution, during the test, the carrier slides in from the side of the plate placing part where the positioning strip is not provided, and thereafter, the pressing plate is driven down by the pressing power module, so that the pressing plate fixes the carrier on the floating plate, and at the same time, the pressing plate pushes the floating plate down, so that the probe module passes through the floating plate and the carrier into the product slot and contacts the panel to be energized, thereby performing the test. After the test is completed, the pressing plate pushes the floating plate to rise and reset, and at this time, the floating plate also rises and resets, so that the probe module is separated from the product slot and the panel, and the carrier can be taken out from the side of the plate placing part where the positioning strip is not provided. Therefore, the utility model has the following beneficial effects:

[0010] 1. Since the carrier plate can slide out or in from the side of the plate placing part where no positioning strip is provided, the carrier plate is provided with a product slot for placing the panel, so that the downward pressure power module does not need to drive the pressing plate to leave enough space away from the plate placing part, and the carrier plate can be taken out or put in, thereby reducing the height and volume of the panel test needle bed;

[0011] 2. Since the probe module needs to enter the product slot and contact the panel to be energized only when the downward power module drives the pressure plate to push the floating plate down, so that when the pressure plate is not pressing down to fix the carrier plate, the probe module can be protected. At the same time, the probe module can prevent the carrier plate from sliding out or in from the side of the plate placing part where the positioning strip is not provided.

[0012] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0013] In some embodiments, the carrier plate is provided with an adjustment rectangular groove connected to the product groove, and the probe module can pass through one position of the adjustment rectangular groove into the product groove to contact and energize the panel;

[0014] According to the technical solution, the carrier board can be placed at different positions of the board placement part by pulling or pushing the carrier board, so that the station inside the panel that needs to be tested is moved above the probe module, so that the probe module can perform contact and power-on testing with different stations inside the panel. Therefore, the utility model further achieves the following beneficial effects:

[0015] 1. It is not necessary to set up multiple sets of probe modules and testing instruments corresponding to the stations that need to be tested inside the panel on the panel test bed, so that all stations that need to be tested inside the panel can be tested, thereby reducing the high testing cost. At the same time, it also avoids electrical signal interference and adverse activities caused by densely arranging probe modules and wiring on the panel test bed;

[0016] 2. Since the carrier board can be placed in different positions of the board placement part, the different stations that need to be tested inside the panel can be moved above the probe module, so that the panel test needle bed can selectively perform spot checks or full inspections on each station of the panel.

[0017] In some embodiments, the placing plate portion is provided with an array of positioning elastic plungers along the side not provided with the positioning strip, and the carrier plate is provided with positioning holes into which the positioning elastic plungers can enter;

[0018] According to the technical solution, when the carrier is in different positions of the board placing part, the carrier is fixed by positioning the elastic plunger into the corresponding positioning hole, so as to avoid displacement of the carrier when the pressure plate is lowered, causing the probe to be unable to contact the work station required for testing of the assembly board, thereby affecting the test accuracy and damaging the probe module.

[0019] In some embodiments, the pressing plate is equipped with an in-position sensor, and the in-position sensor is located above a side of the placing plate portion where no positioning strip is provided;

[0020] According to the technical solution, the in-position sensor is used to identify whether the carrier is located at a specified position on the plate placing part, and then an instruction is issued to control the downward pressure power module to drive the pressure plate to descend, thereby avoiding damage to the carrier and the probe module caused by the pressure plate descending at the wrong time.

[0021] In some embodiments, the press is equipped with a needle mold fixing seat, the probe module is installed on the needle mold fixing seat, the needle mold fixing seat is provided with a floating spring for supporting a floating plate, and the floating plate is equipped with a floating guide column passing through the needle mold fixing seat;

[0022] According to the technical solution, the floating plate can be stably lifted and lowered vertically, thereby preventing the floating plate from deviating during lifting and lowering and causing damage to the probe module.

[0023] In some embodiments, the pressing plate is provided with a first positioning column which can be inserted into the pin mold fixing seat;

[0024] According to the technical solution, when the pressing power module drives the pressing plate to descend, the pressing plate can be accurately pressed down onto the carrier plate and the floating plate.

[0025] In some embodiments, the pressing plate is provided with a positioning groove, and the carrier plate is provided with a second positioning column, and the second positioning column can enter the positioning groove to position the carrier plate and limit the distance between the pressing plate and the carrier plate when the pressing plate descends;

[0026] According to the technical solution, when the pressure plate descends, the second positioning column enters the positioning groove, so that the pressure plate and the carrier are aligned before contacting and fixing with the carrier, and the distance between the pressure plate and the carrier is limited, thereby achieving more accurate fixing and protection of the carrier.

[0027] In some embodiments, a cover plate is provided on the product slot, which is used to cover the panel and can contact the pressing plate; according to the technical solution, when the pressing plate is pressed down onto the carrier plate, the panel can be protected.

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings.

[0039] like Figures 1 to 7 As shown, this specific embodiment provides a panel test needle bed, which includes a press machine 1, and the press machine 1 is equipped with a needle mold fixing seat 5 and a pressing power module 3.

[0040] The needle mold fixing seat 5 is installed with a probe module 51 and a floating spring 24, a floating plate 2 is placed on the probe module 51, the floating spring 24 is used to support the floating plate 2, and a floating guide column 25 passing through the needle mold fixing seat 5 is installed on the bottom wall of the floating plate 2. The top wall of the floating plate 2 is provided with a plate placing portion 21, and three sides of the plate placing portion 21 are installed with positioning strips 22. The plate placing portion 21 is provided with an array of positioning elastic plungers 23 along the side where the positioning strip 22 is not provided.

[0041] The carrier plate 4 is placed in the plate placing part 21, and the top wall of the carrier plate 4 is provided with a product groove 41 and a second positioning column 44. The product groove 41 is used to place the panel 6, and a cover plate 45 for covering the panel 6 is provided on the product groove 41. The bottom wall of the carrier plate 4 is provided with an adjustment rectangular groove 42 connected to the product groove 41. When the floating plate 2 descends, the probe module 51 can pass through one of the positions of the adjustment rectangular groove 42 to enter the product groove 41 and contact the panel 6 for power supply. The carrier plate 4 can slide out or slide in from the side of the plate placing part 21 where the positioning bar 22 is not provided. The bottom wall of the carrier plate 4 is provided with a positioning hole 43 for the positioning elastic plunger 23 to enter.

[0042] The pressing power module 3 drives a pressing plate 31, which can be pressed down onto the carrier plate 4 to contact the cover plate 45 and push the floating plate 2 down. The pressing plate 31 is equipped with an in-position sensor 32, a first positioning column 33 and a positioning groove 34. The in-position sensor 32 is located above the side of the plate placing part 21 where the positioning bar 22 is not provided, so as to identify whether the carrier plate 4 is located at a certain specified position on the plate placing part 21. When the pressing plate 31 is descending, the first positioning column 33 can be inserted into the pin mold fixing seat 5, and the second positioning column 44 can enter the positioning groove 34, so as to position the carrier plate 4 and limit the distance between the pressing plate 31 and the carrier plate 4 when the pressing plate 31 is descending.

[0043] The following is the working process of a panel test needle bed described in this specific implementation method:

[0044] The panel 6 is placed in the product slot 41 on the carrier, and the cover plate 45 is placed on the panel 6; thereafter, the carrier plate 4 slides in from the side of the plate placing portion 21 where the positioning strip 22 is not provided, so that the station inside the panel 6 that needs to be tested moves to above the probe module 51. At this time, the positioning elastic plunger 23 enters the corresponding positioning hole 43 to fix the carrier plate 4; thereafter, the downward pressure power module 3 drives the pressing plate 31 to descend, so that the pressing plate 31 fixes the carrier plate 4 on the floating plate 2. At the same time, the pressing plate 31 pushes the floating plate 2 to descend, so that the probe module 51 passes through the floating plate 2 and The carrier plate 4 enters the product slot 41 and contacts the panel 6 to be energized for testing; after the test is completed, the pressure plate 31 pushes the floating plate 2 to rise and reset, and the floating plate 2 also rises and resets due to the elastic force of the floating spring 24, and the probe module 51 detaches from the product slot 41 and separates from the panel 6; thereafter, the carrier plate 4 can be taken out from the side of the panel placing part 21 where the positioning strip 22 is not provided, or the position of the carrier in the panel placing part 21 can be adjusted by pulling or pushing the carrier plate 4, and other workstations inside the panel 6 that need to be tested are moved to above the probe module 51 for the next round of testing.
