[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0040] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] like Figure 1 - Figure 6 As shown, the foaming device test fixture provided by the present invention includes: a platform 100, on which a screw module detection mechanism is provided. The screw module detection mechanism includes a clamping mechanism 910 for clamping the screw module, and a detection module 810 for detecting the gap between the slider 920 and the screw 930 on the screw module.

[0042] The detection module 810 includes an electrically connected display module and a contact module 812. The contact module 812 is used to be in close contact with the slider 920 to detect the gap. The display module is a dial 811 with a data display function, which is used to display the measured gap.

[0043] Specifically, the clamping mechanism 910 includes a screw 840, a handle 850, and a third fixed plate 820 and a fourth fixed plate 830 arranged at intervals. The screw 840 passes through the third fixed plate 820 and is threadedly connected to the third fixed plate 820; the handle 850 is connected to one end of the screw 840, and the other end of the screw 840 is used to abut the screw module so that the screw module is clamped between the screw 840 and the fourth fixed plate 830.

[0044] The user can place the screw module to be tested between the third fixing plate 820 and the fourth fixing plate 830, and then tighten the screw 840 through the handle 850 so that the screw module is clamped between the screw 840 and the fourth fixing plate 830. After the screw module is fixed, the contact module 812 is placed close to the slider 920 to detect the gap between the screw 930 and the slider 920, and obtain the gap value from the dial 811 to determine whether the screw module meets the requirements. After the clamping mechanism 910 fixes the screw module, the detection module 810 is used for detection, which can avoid the problems of low precision and inaccurate detection results caused by manual observation detection, thereby improving detection efficiency and accuracy.

[0045] The platform 100 is also equipped with a main control PCBA connection structure 200, a touch screen detection mechanism 300, and a photoelectric sensor detection mechanism 400. This foaming device detection fixture can simultaneously detect the main control PCBA, touch screen, and photoelectric sensor, achieving a single-station multi-functional detection effect and greatly improving detection efficiency.

[0046] Platform 100 also includes a power filter bracket 510 for connecting to the power filter 620, a power module bracket 520 for connecting to the power module 610, a main unit switch bracket 530 for connecting to the main unit switch bracket 530, a light board PCBA bracket 540 for connecting to the light board PCBA 690, a main unit-handle PCBA bracket 550 for connecting to the main unit-handle PCBA 760, and snap fasteners for connecting to various other PCBAs. These other PCBAs may also include: a B-module PCBA 710, a Y-axis module PCBA 720, a Z-axis module PCBA 730, a D-axis module PCBA 740, and a BUB module PCBA 750.

[0047] The main control PCBA connection structure 200 includes a first fixing plate 210, a second fixing plate 220, a connecting rod 230, a first slider 240, a second slider 250, and a first spring 260. The first and second fixing plates 210, 220 are arranged parallel to each other and spaced apart. The connecting rod 230 is located between them, with one end connected to the first fixing plate 210 and the other end connected to the second fixing plate 220, securing the three relative to each other.

[0048] The first slider 240 and the second slider 250 are both slidably connected to the connecting rod 230, that is, the first slider 240 and the second slider 250 can slide along the length of the connecting rod 230. The first slider 240 and the second fixing plate 220 are used to clamp the main control PCBA 660. Both can be provided with slots, the thickness of which matches the thickness of the main control PCBA 660, for inserting and clamping the main control PCBA 660.

[0049] The second slider 250 is positioned between the first slider 240 and the first fixed plate 210. The first spring 260 is sleeved on the connecting rod 230, with one end of the first spring 260 abutting the first slider 240 and the other end abutting the second slider 250. The connecting rod 230 is provided with at least two connecting holes 231 along its length. In this embodiment, there are three connecting holes 231. The second slider 250 is provided with a locking member connected to the connecting holes 231. The locking member can be a first screw 270 threadedly connected to the second slider 250. The locking member can be used to select which connecting hole 231 the first screw 270 is connected to based on the length of the main control PCBA 660, thereby adjusting the compression of the first spring 260 to prevent the first slider 240 from being too tight or too loosely clamped to the second fixed plate 220.

[0050] The bottom surface of the first slider 240 is a plane, and the plane contacts the top surface of the platform 100 to prevent the first slider 240 from rotating and avoid the slot from deviating.

[0051] The touch screen detection mechanism 300 includes a touch screen bracket 310. The top surface of the touch screen bracket 310 has a recessed platform 320 for accommodating the touch screen 780. The shape of the recessed platform 320 can be consistent with the shape of the touch screen 780, so that the touch screen 780 can be precisely placed within the recessed platform 320. The side walls of the recessed platform 320 serve as a horizontal limiter for the touch screen 780. The bottom surface of the recessed platform 320 is provided with a downwardly concave groove 330. The shape of the groove 330 is consistent with that of the host-screen magnetic PCBA 770. The groove 330 is used to accommodate the host-screen magnetic PCBA 770, so that after the touch screen 780 is installed on the recessed platform 320, the socket on the back of the touch screen 780 can be plugged into the plug on the host-screen magnetic PCBA 770. Furthermore, two mounting holes can be provided on the bottom surface of the groove 330 , and magnets are provided in both mounting holes, one with its N pole facing upward and the other with its S pole facing upward, corresponding to the two magnets in the touch screen 780 , respectively, so that the touch screen 780 is adsorbed in the sink 320 .

[0052] The side of the touch screen bracket 310 has a notch, which is connected to the sink 320 and the groove 330 to allow the wires connected to the host-screen magnetic PCBA770 to pass through. At the same time, the notch can form a buckle position for buckling the touch screen 780, making it convenient for the user to remove the touch screen 780 from the sink 320.

[0053] The photoelectric sensor detection mechanism 400 includes: a sensor bracket, the sensor bracket includes a connecting base 410 and a support plate 420 connected to the connecting base 410, and the connecting base 410 and the support plate 420 can be an integral structure. The connecting base 410 and the support plate 420 are vertically "L"-shaped. The connecting base 410 is used to connect to the photoelectric sensor 790. A paddle 430 is rotatably connected to the support plate 420. The paddle 430 can be rotated to enter the sensing area of ​​the photoelectric sensor 790 or swing out of the sensing area. When it is necessary to test the PCBA socket related to the photoelectric sensor 790, it can be tested by rotating the paddle 430. Under normal circumstances, the sensing area will light up when the photoelectric sensor 790 is turned on. When the rotating paddle 430 reaches the sensing area of ​​the photoelectric sensor 790, the light in the sensing area will go out, thereby judging whether the PCBA socket is conductive and whether there is a problem with the PCBA.

[0054] The paddle 430 is connected to the support plate 420 via a second screw 440. The cap of the second screw 440 is located on the side of the paddle 430 facing away from the support plate 420. A second spring 450 is disposed between the cap and the paddle 430. One end of the second spring 450 abuts the cap, and the other end abuts the paddle 430. The second spring 450 serves as a temporary positioning mechanism. This means that the paddle 430 can be rotated under external force from the user. Once the user removes the external force applied to the paddle 430, the paddle 430 is compressed between the second spring 450 and the support plate 420 and will not swing back to the sensing area due to gravity.

[0055] The host interface PCBA650 connection structure, the cart bottom plate PCBA630 connection structure, the host-cart connection PCBA640 connection structure and the blood pressure module 670 connection structure all include press buckles.

[0056] The clamping clip includes a third screw, a third spring, and a rotary clamping member. The third screw passes through the rotary clamping member and connects to the platform 100. The third screw is sleeved onto the third screw, and one end of the third spring abuts the cap of the third screw, while the other end abuts the rotary clamping member. The third spring applies a downward force to the rotary clamping member, thereby achieving a clamping effect. The user can apply an upward force to the rotary clamping member to lift it, placing the PCBA to be clamped underneath it.

[0057] The power supply process of the whole machine test fixture: the power filter 620, the power module 610, and the cart bottom plate PCBA630 are connected. The power filter 620 is connected to the external power supply to supply power to the cart bottom plate PCBA630. The cart bottom plate PCBA630 is connected to the host interface PCBA650, the host interface PCBA650 is connected to the main control PCBA660, and the remaining PCBAs are all connected to the main control PCBA660. (Adopting the principle of proximity, the PCBAs that need to be connected to the main control are designed to be close to its socket to prevent tangling during the connection process.) The main control PCBA660 controls the operation. At this point, the whole machine test fixture is fully conductive. If incoming material inspection is required, just connect the sample to the corresponding PCBA socket to complete the functional inspection. At the same time, you can also replace the PCBA to inspect each PCBA for problems.

[0058] Most PCBAs use the column plane direction limiter, and then use the buckle to press the PCBA; the buckle can be rotated, and when the PCBA needs to be replaced, just rotate the buckle to the side.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
