Description

Technical Field

[0001] The utility model is applied to the technical field of fingerprint testing under a mobile phone screen, and particularly relates to a test clamping mechanism. Background Art

[0002] The fingerprint function under the screen is currently the mainstream anti-theft and confidentiality means for mobile phones. A high proportion of new mobile phones on the market have the fingerprint function under the screen. Manufacturers need to test the equipment before leaving the factory. The market prospect of this test equipment is broad and the demand is large. Reducing the upgrade cost of the test equipment can effectively improve the competitiveness of the product. The clamping mechanism is an auxiliary mechanism of the test equipment, which is used to place and clamp the mobile phone in the fingerprint test under the mobile phone screen. The product needs to be clamped and positioned before testing.

[0003] At present, the clamping mechanisms of mainstream mobile phone under-screen fingerprint testing equipment on the market are mostly "dedicated to special machines". After the manufacturer updates the new mobile phone, it is necessary to adapt the new test equipment, or update the old equipment to the new equipment by updating the tray module. The mobile phone placement module of the equipment is customized according to the external dimensions of the tested mobile phone. Obviously, the cost of updating and iteration is high, it is not convenient to upgrade and replace, and the compatibility is poor. For example, the Chinese patent with publication number CN206105678U adjusts the lateral position of the clamping block assembly and the vertical position of the clamping block assembly respectively through the lateral adjustment assembly and the vertical adjustment assembly to achieve the purpose of clamping the mobile phone to be tested. However, its adjustment speed is slow, and it is difficult to accurately control the clamping force by manual adjustment. After the clamping process is completed, it is necessary to manually plug and unplug the USB module to realize the conduction of the test data, and the degree of automation is low. Therefore, it is necessary to provide a test clamping mechanism with compact structure, low cost, good compatibility, and effective improvement of production efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a test clamping mechanism which has a compact structure, low cost, good compatibility and effectively improves production efficiency.

[0005] The technical solution adopted by the utility model is: the utility model includes a tray, on which a side pressure module, a placement module and a USB module are arranged, the placement module includes a positioning plate, and blocks are arranged at both the front and rear ends and the left and right ends of the positioning plate, the USB module includes a test connector connected to an external testing machine, and the test connector is directly opposite to the front end of the positioning plate, the side pressure module includes a first driving cylinder, and the action end of the first driving cylinder is provided with a push block, and the push block is tilted to point to the rear end of the positioning plate.

[0006] It can be seen from the above scheme that the placement module is used to place the mobile phone product. The placement module is customized according to the external dimensions of the mobile phone product. The USB module serves as a bridge between the external testing machine and the mobile phone product and is used to test data conduction. The side pressure module drives the push block to move through the first driving cylinder, driving the mobile phone product to be close to the block, laying the foundation for the test connector to be accurately plugged into the wire plug hole of the mobile phone product. When the manufacturer updates the mobile phone product, there is no need to replace the entire test clamping mechanism, but only need to replace the placement module to complete the upgrade, thereby achieving multi-compatibility, effectively reducing the manufacturer's cost, while reducing the difficulty of equipment upgrades and effectively improving production efficiency.

[0007] A preferred solution is that four groups of symmetrically arranged pads are provided on the upper surface of the positioning plate, the four groups of pads are distributed in 2X2, and the heights of the four groups of pads are all consistent.

[0008] A preferred solution is that a first mounting groove is opened on the upper surface of the positioning plate, and an NFC chip electrically connected to an external host computer is provided in the first mounting groove, and the NFC chip is slidably arranged in the first mounting groove along the front-rear direction of the positioning plate.

[0009] A preferred solution is that a second mounting groove is formed on the upper surface of the positioning plate, and an infrared photoelectric sensor is disposed in the second mounting groove.

[0010] A preferred solution is that the USB module also includes a second driving cylinder, which is driven along the front-rear direction of the positioning plate, and the action end of the second driving cylinder is provided with a mounting block, and the test connector is arranged at the end of the mounting block.

[0011] A preferred solution is that the push block is a V-shaped structure, the angle bisector of the V-shaped structure is aligned with the diagonal of the positioning plate, the upper layer of the push block is a hard structure, and the lower layer of the push block is a soft structure, and the soft structure serves as the contact end of the push block.

[0012] A preferred solution is that the side pressure mold group also includes a fixed block, the first driving cylinder is connected to the top of the fixed block, the bottom of the fixed block is connected to the tray, the movement range of the fixed block along the left and right directions of the positioning plate is 0-25mm, the fixed block is provided with an arc groove, the first driving cylinder is connected to the fixed block through the arc groove, and the angle of the arc groove is 30 degrees.

[0013] A preferred solution is that a U-shaped groove is provided at a diagonal position of the positioning plate, and a positioning block is connected to the lower end of the first driving cylinder, and the positioning block is adapted to the U-shaped groove.

[0019] like Figure 1 As shown, in this embodiment, the utility model includes a tray 1, on which a side pressure module 2, a placement module 3 and a USB module 4 are provided, the placement module 3 includes a positioning plate 31, and blocks 32 are provided at both the front and rear ends and the left and right ends of the positioning plate 31, the USB module 4 includes a test connector 41 connected to an external testing machine, and the test connector 41 is directly opposite to the front end of the positioning plate 31, the side pressure module 2 includes a first driving cylinder 21, and the action end of the first driving cylinder 21 is provided with a push block 22, and the push block 22 is tilted to point to the rear end of the positioning plate 31.

[0020] An external manipulator or operator places the mobile phone product on the positioning plate 31. The first driving cylinder 21 is located at the upper right corner of the positioning plate 31. The first driving cylinder 21 drives the push block 22 to move forward. The push block 22 pushes the mobile phone product to be close to the stop block 32 at the left end and the stop block 32 at the right end of the positioning plate 31, so that the test connector is accurately inserted into the wire plug hole of the mobile phone product.

[0021] To achieve test data conduction, the external test module is located above the test clamping mechanism, and the external test module drives the screen of the touch mobile phone product to achieve fingerprint testing under the mobile phone screen. The side pressure module 2 adopts a unilateral positioning method of side push clamping to ensure that the test connector 41 is accurately inserted into the plug hole of the mobile phone product. Since there is a design redundancy of about one millimeter between the spacing of the block 32 at the left and right ends and the width of the mobile phone product, if a direct push method is adopted, it is impossible to ensure that the test connector 41 is accurately inserted into the plug hole of the mobile phone product. The side pressure module 2 pushes the mobile phone product to the side, which is fixed, effectively avoiding the risk of collision.

[0022] like Figure 2 As shown, in this embodiment, four groups of symmetrically arranged pads 33 are arranged on the upper surface of the positioning plate 31, and the four groups of pads 33 are arranged in a 2X2 distribution, and the heights of the four groups of pads 33 are all consistent. It is ensured that the mobile phone product is placed flat on the positioning plate 31, which lays a foundation for the test connector 41 to be accurately plugged into the plug hole of the mobile phone product.

[0023] like Figure 2 As shown, in this embodiment, the upper surface of the positioning plate 31 is provided with a first installation groove 34, and the first installation groove 34 is provided with an NFC chip 35 electrically connected to an external host computer, and the NFC chip 35 is slidably arranged in the first installation groove 34 along the front-back direction of the positioning plate 31, so that the debugging personnel can confirm the appropriate position of the NFC chip 35 according to the sensitivity. The NFC chip 35 plays the role of exchanging information and records whether the mobile phone product has been detected.

[0024] like Figure 1 As shown, in this embodiment, a second mounting groove 36 is formed on the upper surface of the positioning plate 31, and an infrared photoelectric sensor 37 is disposed in the second mounting groove 36. The infrared photoelectric sensor 37 is used to detect whether there is a mobile phone product at the position.

[0025] like Figure 3 As shown, in this embodiment, the USB module 4 also includes a second driving cylinder 42, which is driven along the front-to-back direction of the positioning plate 31, and a mounting block 43 is provided at the action end of the second driving cylinder 42, and the test connector 41 is provided at the end of the mounting block 43.

[0026] The second driving cylinder 42 drives the mounting block 43 to move, thereby driving the test connector 41 to be precisely plugged into the wire insertion hole of the mobile phone product.

[0027] like Figure 4 As shown, in this embodiment, the push block 22 is a V-shaped structure, the angle bisector of the V-shaped structure is aligned with the diagonal of the positioning plate 31, the upper layer of the push block 22 is a hard structure, and the lower layer of the push block 22 is a soft structure, and the soft structure serves as the contact end of the push block 22.

[0028] The soft structure can prevent the mobile phone from being damaged during squeezing.

[0029] like Figure 1As shown, in this embodiment, the side pressure mold group 2 also includes a fixed block 23, the first driving cylinder 21 is connected to the top of the fixed block 23, the bottom of the fixed block 23 is connected to the tray 1, the movement range of the fixed block 23 along the left and right directions of the positioning plate 31 is 0-25mm, the fixed block 23 is provided with an arc groove, the first driving cylinder 21 is connected to the fixed block 23 through the arc groove, and the angle of the arc groove is 30 degrees.

[0030] In the test of the same batch of mobile phones, the test clamping mechanism does not need to be adjusted. When measuring the function of another mobile phone product with a different size, the placement module 3 needs to be remade, so there are some differences in the positioning angles. The lateral adjustment is achieved through the movement range of the fixed block 23 along the left and right directions of the positioning plate 31, and the angle adjustment is achieved through the arc groove, which has good practicality.

[0031] like Figure 2 and Figure 4 As shown, in this embodiment, a U-shaped groove 38 is opened at the diagonal of the positioning plate 31, and a positioning block 39 is connected to the lower end of the first driving cylinder 21. The positioning block 39 is adapted to the U-shaped groove 38, thereby playing a guiding and positioning role.

[0032] like Figure 1 As shown, in this embodiment, four groups of side pressure modules 2, four groups of placement modules 3 and four groups of USB modules 4 are arranged on the tray 1, and the side pressure modules 2, the placement modules 3 and the USB modules 4 are matched with each other.
