Description

Technical Field

[0001] The invention relates to the technical field of automatic crimping of vehicle-mounted panels, and in particular to an FPC board pressing head device and an FPC board crimping equipment. Background Art

[0002] With the continuous advancement of science and technology, display panel technology has developed rapidly and is widely used in mobile phones, computers and other fields. In order to ensure the service life of mobile phone and computer screens, a series of performance index tests need to be performed on the display panel after it is manufactured. When testing the performance index of the display panel, a conductive pressure head is usually used to press the flexible circuit board (FPC board) bound to the display panel to achieve signal transmission and ensure the lighting of the display panel screen.

[0003] The probe mechanism, diffuser plate and mounting part in the existing press head structure are generally independent parts. When the FPC board is crimped, the FPC board will contact the top of the probe mechanism and the mounting part at the same time. However, when the press head structure is assembled, it may not be possible to ensure that the upper surfaces of multiple processed parts such as the probe mechanism and the mounting part are on the same horizontal plane, which will cause the FPC board to rub against the raised processed parts when it is close to the press head structure, resulting in crimping failure. At the same time, since the probe on the probe mechanism is exposed to the air for a long time, multiple crimping may cause the probe to be damaged, affecting the crimping effect. Summary of the invention

[0004] The present invention provides an FPC board pressing head device and an FPC board crimping equipment to solve all or part of the problems in the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides an FPC board press head device, comprising a mounting mechanism, a transfer mechanism arranged on the mounting mechanism, the transfer mechanism contacts the bottom end of the probe on the probe mechanism through a floating module, the outer end of the probe mechanism covers the outer end of the mounting mechanism, and at least one group of elastic components is arranged on the floating module to support and fix the probe mechanism so that the top end of the probe is hidden in the probe mechanism in a static state, and the probe mechanism moves downward to expose the top end of the probe during crimping. The probe mechanism and the mounting mechanism in the existing press head structure are independent structures. When the FPC board is crimped and tested, the FPC board will contact the probe mechanism and the mounting structure at the same time. The outer end of the probe mechanism in the present invention covers the outer end of the mounting mechanism, so that the FPC board is directly transferred to the top of the probe mechanism during transmission, without contacting the probe mechanism and the mounting part at the same time, reducing the risk of crimping failure caused by the fact that multiple processed parts may not be in the same horizontal plane after assembly. At the same time, a floating module is arranged on the press head device, so that the probe will only pass through the probe mechanism and contact the product to be tested in the crimped state, and is placed inside the probe mechanism when not crimped, which plays a good protective role for the probe and reduces the risk of probe damage.

[0006] The elastic component includes a spring arranged on the floating module and a spring guide column arranged on the probe mechanism, and the bottom end of the spring guide column contacts the top end of the spring. Further, in the un-crimped state, the spring guide column and the spring include two states, one is that a portion of the length of the spring guide column exceeds the lower surface of the probe mechanism and extends into the floating module, and the other is that a portion of the length of the spring exceeds the upper surface of the floating module and extends into the probe mechanism.

[0007] The mounting mechanism is provided with an illumination device, and the probe mechanism is provided with a diffusion device located above the illumination device, and the diffusion device is at the same level as the upper surface of the probe mechanism. The diffusion device is at the same level as the upper surface of the probe mechanism to prevent the product to be tested from rubbing against the raised workpiece when approaching the pressure head structure, causing a crimping failure.

[0008] The probe mechanism also includes a positioning device for limiting the position of the product to be tested. The present invention adds a positioning device to the probe mechanism, which facilitates the camera to accurately capture the FPC board to be tested, obtain the position of the FPC board to be tested, and improve the success rate of crimping.

[0009] The positioning device includes a first positioning member parallel to one side of the product to be tested. The positioning camera takes a picture of the first positioning member and the side of the product to be tested under the action of the lighting device to obtain the position information of the product to be tested. The positioning camera obtains the position information of the product to be tested by taking pictures of the side of the product to be tested and the first positioning member. The background system adjusts the position of the product to be tested according to the aforementioned position information so that the product to be tested is placed in the correct crimping position to ensure the crimping effect.

[0010] At least one positioning mark is provided on the product to be tested, and the positioning device further includes a second positioning member provided corresponding to the positioning mark. The positioning camera takes a picture of the first positioning member and the positioning mark under the action of the lighting device to obtain the position information of the product to be tested. The positioning device further includes a second positioning member provided corresponding to the positioning mark on the product to be tested, and the second positioning member is a light-transmitting hole. The light emitted by the lighting device is irradiated on the positioning mark through the diffusion device and the second positioning member, so as to facilitate the observation of the positioning mark. By taking pictures of the side, the positioning mark and the first positioning member on the probe mechanism on the product to be tested, the accurate position information of the product to be tested is obtained.

[0011] The end of the probe mechanism away from the diffusion device is provided with an oblique guide for the product to be tested to slide. One end of the probe mechanism is provided as an oblique guide, so that the product can slide onto the probe mechanism along the oblique guide, avoiding the product directly being inserted into the bottom of the pressure head and causing crimping failure.

[0012] The transfer mechanism is a transfer FPC board, one end of which is connected to the power supply device, and the other end is connected to the bottom of the probe. When the product to be tested is crimped, the current in the power supply device flows from the transfer FPC board through the probe to the product to be tested, thereby realizing the crimping point screen of the product to be tested.

[0013] The lighting device includes backlight strips arranged in rows or columns.

[0014] The present invention also provides an FPC board crimping device, comprising a pressing module and an FPC board pressing head device according to any one of the above technical solutions, wherein the pressing module presses the probe mechanism to expose the probe tip.

[0015] The beneficial effects of the present invention are:

[0016] (1) The present invention covers the outer end of the mounting mechanism with the outer end of the probe mechanism, so that the FPC board is directly transferred to the top of the probe mechanism during transmission, without the need to contact the probe mechanism and the mounting part at the same time, thereby reducing the risk of crimping failure caused by the fact that multiple workpieces may not be on the same horizontal plane after assembly. At the same time, a floating module is set on the pressure head structure, so that the probe will only pass through the probe mechanism and contact the product to be tested in the crimped state, and is placed inside the probe mechanism when not in the crimped state, which plays a good protective role for the probe and reduces the risk of probe damage.

[0017] (2) The present invention adds a positioning device to the probe mechanism, which makes it easier for the camera to accurately capture the image of the FPC board to be tested and obtain the position of the FPC board to be tested, and makes it easier for the background system to adjust the position of the FPC board to be tested, thereby improving the success rate of crimping.

[0030] Example 1

[0031] This embodiment provides an FPC board pressing head device, such as Figure 1 Shown and Figure 3 As shown, the pressing head device 1 includes a mounting mechanism 101 and a transfer mechanism 102 arranged on the mounting mechanism 101. The transfer mechanism 102 contacts the bottom end of the probe 1032 on the probe mechanism 103 through a floating module 104. The outer end of the probe mechanism 103 covers the outer end of the mounting mechanism 101. A plurality of groups of elastic components 3 are arranged on the floating module 104 to support and fix the probe mechanism 103 so that the top end of the probe 1032 is hidden in the probe mechanism 103 in a stationary state. When crimping, the probe mechanism 103 moves downward to expose the top end of the probe 1032.

[0032] The probe mechanism and the mounting mechanism in the existing pressure head structure are independent structures. When the FPC board is crimped, the FPC board will contact the probe mechanism and the mounting structure at the same time. The outer end of the probe mechanism in the present invention covers the outer end of the mounting mechanism, so that the FPC board is directly transferred to the top of the probe mechanism during transmission, without the need to contact the probe mechanism and the mounting part at the same time, reducing the risk of crimping failure caused by multiple workpieces not being able to be on the same horizontal plane after assembly. At the same time, a floating module is set on the pressure head device, so that the probe will only pass through the probe mechanism and contact the product to be tested in the crimped state, and is placed inside the probe mechanism 103 when not crimped, which plays a good protective role for the probe and reduces the risk of probe damage.

[0033] The mounting mechanism 101 is provided with an illumination device 1011, and the illumination device 1011 includes backlight strips arranged in rows or columns. The probe mechanism 103 includes a diffusion device 1031 located above the illumination device 1011, and the diffusion device 1031 is a diffusion plate, and the diffusion plate and the upper surface of the probe mechanism 103 are on the same horizontal plane.

[0034] like Figure 2 As shown, the elastic component 3 includes a spring 301 disposed on the floating module 104 and a spring guide column 302 disposed on the probe mechanism 103, and the bottom end of the spring guide column 302 contacts the top end of the spring 301. In this embodiment, in the non-crimped state, a portion of the length of the spring guide column 302 exceeds the lower surface of the probe mechanism 103 and extends into the floating module 104. In other embodiments, it can be set that a portion of the length of the spring 301 exceeds the upper surface of the floating module 104 and extends into the probe mechanism 103.

[0035] like Figure 1 and Figure 3As shown, a plurality of positioning marks 201 are arranged on the product to be tested 2, and a positioning device 1033 is arranged on the probe mechanism 103, including a first positioning piece 1033-1 parallel to one side of the product to be tested 2, and a second positioning piece 1033-2 arranged corresponding to the product to be tested 201, wherein the second positioning piece 1033-2 is a light-transmitting hole, and the light emitted by the illuminating device 1011 is irradiated onto the product to be tested 201 through the diffusion device 1031 and the second positioning piece 1033-2, so as to facilitate observation of the product to be tested 201, and by taking pictures of the side of the product to be tested 2, the product to be tested 201 and the first positioning piece 1033-1 on the probe mechanism 103, accurate position information of the product to be tested 2 is obtained, and the background system adjusts the position of the product to be tested 2 according to the aforementioned position information, so that the product to be tested 2 is placed in the correct crimping position to ensure the crimping effect. In other embodiments, the positioning device 1033 may only include a first positioning member 1033-1 parallel to a side edge of the product to be tested 2, and the positioning camera obtains the position information of the product to be tested 2 by taking pictures of the first positioning member 1033-1 and the side edge of the product to be tested 2.

[0036] like Figure 4 As shown, the end of the probe mechanism 103 away from the diffusion device 1031 is provided with an inclined guide 1034 for the tested product 2 to slide. One end of the probe mechanism 103 is provided as an inclined guide 1034, so that the product can slide onto the probe mechanism 103 along the inclined surface, avoiding the product directly being inserted into the bottom of the press head and causing crimping failure.

[0037] The transfer mechanism 102 is a transfer FPC board, one end of which is connected to a power supply device (not shown in the figure), and the other end is connected to the bottom end of the probe 1032. When the product 2 to be tested is crimped, the current in the power supply device flows from the transfer FPC board through the probe 1032 to the product 2 to be tested, thereby realizing the crimping point screen of the product 2 to be tested.

[0038] Example 2

[0039] This embodiment provides an FPC board crimping device, including a pressing module and the FPC board pressing head device in embodiment 1, such as Figure 5As shown, the pressing module 4 includes a first pressing member 401 for pressing the probe mechanism 103 and a second pressing member 402 for pressing the product to be tested 2. When the FPC crimping device is used to crimp the FPC board to be tested, the FPC board to be tested is placed on the probe mechanism 103, and the positioning camera observes the product to be tested 201, the side and the positioning device 1033 on the probe mechanism 103 on the FPC to be tested through the lighting device 1011 and the diffusion device 1031, and obtains the position information of the FPC board to be tested. The system background adjusts the FPC board to be tested to be located in the correct crimping position according to the position information. Under the pressure of the first pressing member 401 on the pressing module, the probe mechanism 103 exposes the top of the probe 1032, so that the probe 1032 contacts the gold finger on the FPC board to be tested, and the second pressing member 402 on the pressing module crimps the FPC board to be tested.

[0040] In addition, it should be noted that in this specification, "includes", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0041] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
