[0044] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of the embodiments of this utility model, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0045] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

[0046] Furthermore, it should be noted that the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0047] With the rapid development of the PCB industry, a problem has been troubling many PCB manufacturers: during the production process, PCB hangers used to hold PCBs may develop abnormalities that are not easily detected by operators. These abnormalities only become apparent after a large number of finished PCBs have been found, resulting in significant economic losses.

[0048] To solve the above-mentioned technical problems, this utility model proposes a circuit board bracket testing device.

[0049] Please see Figure 1 In one embodiment of this utility model, the circuit board bracket 3 testing equipment is applied to the circuit board bracket 3; specifically, the circuit board bracket 3 testing equipment includes:

[0050] The frame 1 is provided with a first inspection station 101 and a second inspection station 102; the first inspection station 101 is provided with a first inspection component, and the second inspection station 102 is provided with a second inspection component.

[0051] Slide rail 2 is installed on frame 1; circuit board bracket 3 can slide along slide rail 2 to the first inspection station 101 or the second inspection station 102.

[0052] When the circuit board bracket 3 slides to the first testing station 101, the circuit board bracket 3 is subjected to a first functional test by the first testing component; when the circuit board bracket 3 slides to the second testing station 102, the circuit board bracket 3 is subjected to a second functional test by the second testing component.

[0053] The technical solution of this utility model involves setting a first inspection station 101 and a second inspection station 102 on the frame 1, wherein the first inspection station 101 and the second inspection station 102 are respectively equipped with a first inspection component and a second inspection component. When the circuit board bracket 3 slides along the slide rail 2 to the first inspection station 101, the first inspection component performs a first functional inspection on the circuit board bracket 3, which includes upper clamp coplanarity inspection, lower clamp coplanarity inspection, left and right skew inspection, front and back skew inspection, and conductive block wear detection, etc. When the circuit board bracket 3 slides along the slide rail 2 to the second inspection station 102, the second inspection component performs a second functional inspection on the circuit board bracket 3, which includes clamping force detection and resistance detection, etc. By combining the first inspection component and the second inspection component, the circuit board bracket 3 can be inspected in multiple ways, thereby enabling early detection of any abnormalities in the circuit board bracket 3 and avoiding economic losses caused by such abnormalities.

[0054] Furthermore, since the aforementioned testing items are divided into a first testing station 101 and a second testing station 102 for separate testing, when one circuit board bracket 3 is located at the first testing station 101 for the first functional test, the other circuit board bracket 3 can be located at the second testing station 102 for the second functional test. In other words, it can accommodate two circuit board brackets 3 for different functional tests at the same time, thereby improving the testing efficiency of the circuit board brackets 3.

[0055] Specifically, the first detection component includes:

[0056] (1) Upper fixture coplanar detection device, see attached document. Figure 2-3 The upper clamp coplanarity detection device includes a first detection plate 401. The first end of the first detection plate 401 is rotatably connected to the frame 1, and the second end of the first detection plate 401 is provided with a first detection bevel 402. The first detection bevel 402 is used to align with the clamping surfaces of the upper clamps 301 of the circuit board bracket 3. With this configuration, by rotating the first detection plate 401 so that its first detection bevel 402 aligns with the clamping surfaces of the upper clamps 301 in the circuit board bracket 3, and then using the tip of the first detection bevel 402 as a reference, the device visually observes whether the clamping surfaces of all upper clamps 301 are on the same plane, thereby determining whether the clamping surfaces of all upper clamps 301 are coplanar. In this embodiment, the acceptable range for the coplanarity of the clamping surfaces of the upper clamps 301 is 1 ± 0.5 mm.

[0057] A first locking device (not shown in the attached drawings) is provided at the hinge joint between the first detection plate 401 and the frame 1. When the first detection plate 401 rotates until its first detection angle 402 aligns with the clamping surface of the upper clamp 301 of the circuit board bracket 3, the first locking device locks the hinge joint between the first detection plate 401 and the frame 1. This ensures that the first detection plate 401 remains fixed during coplanar detection of the upper clamp, preventing shaking that could affect the coplanar detection effect. In this embodiment, the first locking device can be a butterfly screw.

[0058] Further, see attached document. Figure 4 The surface of the first detection bevel 402 is provided with a first scale value 403, which is used to align with the upper clamp 301. This configuration establishes a preset correspondence between the first scale value 403 and the upper clamp 301. By visually observing whether the upper clamp 301 is within the preset range of the first scale value 403, it is determined whether the upper clamp 301 is in a vertical position, thus completing the verticality detection of the upper clamp 301. In this embodiment, the acceptable verticality detection range for the upper clamp 301 is 0±1mm.

[0059] (2) Lower fixture coplanar detection device, see attached document. Figure 5-6 The lower clamp coplanarity detection device includes a second detection plate 501. The first end of the second detection plate 501 is rotatably connected to the frame 1, and the second end of the second detection plate 501 is provided with a second detection bevel 502. The second detection bevel 502 is used to align with the clamping surface of the lower clamp 302 of the circuit board bracket 3. With this configuration, by rotating the second detection plate 501 so that its second detection bevel 502 aligns with the clamping surface of the lower clamp 302 in the circuit board bracket 3, and then using the tip of the second detection bevel 502 as a reference, the device visually observes whether the clamping surfaces of all lower clamps 302 are on the same plane, thereby determining whether the clamping surfaces of all lower clamps 302 are coplanar. In this embodiment, the acceptable range for the coplanarity of the clamping surfaces of the lower clamps 302 is 1 ± 0.5 mm.

[0060] A second locking device (not shown in the attached diagram) is provided at the hinge joint between the second detection plate 501 and the frame 1. When the second detection plate 501 rotates until its second detection angle 502 aligns with the clamping surface of the lower clamp 302 of the circuit board bracket 3, the second locking device locks the hinge joint between the second detection plate 501 and the frame 1. This ensures that the second detection plate 501 remains fixed during the coplanar detection of the lower clamp, preventing shaking that could affect the coplanar detection effect. In this embodiment, the second locking device can be a butterfly screw.

[0061] Furthermore, the surface of the second detection bevel 502 is provided with a second scale value (not shown in the attached figure), which is used to align with the lower clamp 302. This configuration establishes a preset correspondence between the second scale value and the lower clamp 302. By visually observing whether the lower clamp 302 is within the preset range of the second scale value, it is determined whether the lower clamp 302 is in a vertical position, thus completing the verticality detection of the lower clamp 302. In this embodiment, the acceptable verticality detection range for the lower clamp 302 is 0±1mm.

[0062] (3) Left and right deviation detection device 6, see attached document. Figure 7-8 The left-right skew detection device 6 includes two third detection plates 601, which are rotatably connected to the frame 1. The two third detection plates 601 are located on the left and right sides of the guide post 303 of the circuit board bracket 3, respectively. With this configuration, the circuit board bracket 3 typically has a guide post 303. By observing the positional relationship between the guide post 303 and the two third detection plates 601 located on its left and right sides, it can be determined whether the circuit board bracket 3 is skewed. In the actual detection process, the third detection plates 601 are rotated so that the two third detection plates 601 are located on the left and right sides of the guide post 303, respectively. The third detection plates 601 have been pre-calibrated. In this embodiment, a 3.5mm gap is reserved between the third detection plates 601 and the guide post 303. If the third detection plate 601 touches the guide post 303, it indicates that the circuit board bracket 3 is tilted to the left or right and needs to be replaced and corrected; if the third detection plate 601 does not touch the guide post 303, it indicates that the circuit board bracket 3 is not tilted to the left or right.

[0063] (4) Front and rear skew detection device 7, see attached document. Figure 5 and appendix Figure 9The front-to-back skew detection device 7 includes two fourth detection plates 701, which are mounted opposite each other on a sliding plate 702. The sliding plate 702 is slidably connected to the frame 1. The two fourth detection plates 701 are located on the front and rear sides of the guide post 303, respectively. With this configuration, the circuit board bracket 3 typically has a guide post 303. By observing the positional relationship between the guide post 303 and the two fourth detection plates 701 located on its front and rear sides, it can be determined whether the circuit board bracket 3 is in a front-to-back skew state. The two fourth detection plates 701 are mounted opposite each other on the sliding plate 702, so that the three components combine to form a U-shaped structure. In the actual detection process, the sliding plate 702 is slid so that the two fourth detection plates 701 are located on the front and rear sides of the guide post 303, respectively. The fourth detection plates 701 have been pre-calibrated in position. In this embodiment, a 3.5mm gap is reserved between the fourth detection plates 701 and the guide post 303. If the fourth detection plate 701 touches the guide post 303 during the sliding process of the sliding plate 702, it indicates that the circuit board bracket 3 is misaligned and needs to be replaced and corrected; if the fourth detection plate 701 does not touch the guide post 303, it indicates that the circuit board bracket 3 is not misaligned.

[0064] (5) Conductive block wear detection device 8, see attached document. Figure 10The conductive block wear detection device 8 includes a detection block 801, which is slidably connected to the detection reference surface 103 of the frame 1. The detection end of the detection block 801 is provided with a first step surface 802 and a second step surface 803. The vertical height of the first step surface 802 is set as the initial height of the conductive block 304 of the circuit board bracket 3, and the vertical height of the second step surface 803 is set as the limit height after the conductive block 304 has worn down. With this configuration, the circuit board bracket 3 typically has a conductive block 304, which is used as a power transmission medium to drive the circuit board bracket 3 to slide along the processing guide rail. At the same time, since the conductive block 304 will be worn down to a certain extent during operation, when the wear of the conductive block 304 exceeds the allowable wear amount, it can no longer effectively serve as a power transmission medium. Therefore, it is necessary to detect the wear of the conductive block 304. In the actual testing process, the test block 801 is first placed on the testing reference surface 103 of the frame 1. The operator manually slides the test block 801 horizontally along the testing reference surface 103 to move the testing end of the test block 801 to the position of the conductive block 304. By observing the positional relationship between the conductive block 304 and the first step surface 802 and the second step surface 803, the wear of the conductive block 304 is determined. Specifically, when the conductive block 304 is in a brand new, unworn state, it is in contact with the first step surface 802. When the wear of the conductive block 304 exceeds the allowable wear, its vertical height is higher than that of the second step surface 803, meaning the test block 801 can slide through the bottom of the conductive block 304 without contacting the second step surface 803. In this case, the conductive block 304 needs to be replaced promptly. In this embodiment, the maximum allowable wear of the conductive block 304 is 8mm.

[0065] (6) A level detection device for the main body of the hanging bracket, comprising an electronic level (not shown in the attached figure); the electronic level is placed horizontally at the top of the circuit board hanging bracket 3, and the level of the circuit board hanging bracket 3 is determined by observing the electronic level. In this embodiment, the acceptable level range of the circuit board hanging bracket 3 is 0±0.25°.

[0066] Specifically, the second detection component includes:

[0067] (1) Clamping force detection device. The clamping force detection device includes a tensiometer (not shown in the attached drawings). The tensiometer is used to measure the clamping force of each upper clamp 301 and lower clamp 302 of the circuit board holder 3. During the actual detection process, use a special clamp-opening tool to open each upper clamp 301 and lower clamp 302 one by one, and then place the detection end of the tensiometer in the upper clamp 301 or lower clamp 302. By applying a certain degree of pulling force to the tensiometer and observing whether the upper clamp 301 or lower clamp 302 can hold the tensiometer tightly, it is determined whether the clamping force of the upper clamp 301 / lower clamp 302 meets the expectation. In this embodiment, the clamping force of the upper clamp 301 / lower clamp 302 ≥ 13N is qualified.

[0068] Furthermore, referring to the attached Figure 11 , the frame body 1 is provided with a support device 9. The support device 9 is used to abut and support the back side of the lower clamp 302 when the clamping force of the lower clamp 302 is detected. Specifically, the support device 9 includes a connected support plate 901 and a second driving cylinder 902. Under the driving action of the second driving cylinder 902, the support plate 901 abuts against the back side of the lower clamp 302. With such a setting, considering that the position of the lower clamp 302 is relatively far from the main body part of the circuit board holder 3, directly applying a pulling force to the lower clamp 302 with a tensiometer may cause the connecting frame 306 between the lower clamp 302 and the main body part of the circuit board holder 3 to deform. Based on the above considerations, in this embodiment, a support device 9 is provided at the position of the frame body 1 corresponding to the lower clamp 302. Before the clamping force of the lower clamp 302 is detected, the support plate 901 is abutted against the back side of the lower clamp 302 through the second driving cylinder 902, so as to abut and support the lower clamp 302 and prevent the connecting frame 306 between the lower clamp 302 and the main body part of the circuit board holder 3 from deforming.

[0069] (2) Resistance detection device. The resistance detection device includes a resistance meter (not shown in the attached drawings). The resistance meter is used to measure the resistance value of each upper clamp 301 and lower clamp 302 of the circuit board holder 3. During the actual detection process, use a special clamp-opening tool to open each upper clamp 301 and lower clamp 302 one by one, and then place the detection end of the resistance meter in the upper clamp 301 or lower clamp 302. Measure the resistance value of the upper clamp 301 or lower clamp 302 through the resistance meter to determine whether the resistance value of the upper clamp 30 I / lower clamp 302 meets the expectation. In this embodiment, the resistance value of the upper clamp 301 / lower clamp 302 ≤ 1mΩ is qualified.

[0070] As a preferred solution of the above embodiment, referring to the attached Figure 12Both the first testing station 101 and the second testing station 102 are equipped with positioning devices 10. The positioning devices 10 are used to fix the circuit board bracket 3 in the first testing station 101 or the second testing station 102. With this configuration, the circuit board bracket 3 is fixed in the first testing station 101 or the second testing station 102 by the positioning devices 10, so as to ensure that the circuit board bracket 3 will not shift or shake when performing the first functional test or the second functional test, thereby ensuring the accuracy of the functional test of the circuit board bracket 3.

[0071] There are many specific structures for the positioning device 10. In this embodiment, the positioning device 10 includes a positioning clamp 1001 and a first driving cylinder 1002 connected to each other. Under the driving action of the first driving cylinder 1002, the positioning clamp 1001 clamps and fixes the circuit board bracket 3. With this configuration, using the first driving cylinder 1002 as a power source to drive the positioning clamp 1001 to clamp and fix the circuit board bracket 3, the circuit board bracket 3 is fixedly positioned at the first inspection station 101 or the second inspection station 102. The structure is simple and practical.

[0072] As a preferred embodiment of the above embodiments, refer to the appendix. Figure 12 The frame 1 is equipped with a one-way wheel detection device 11, which is used to detect the one-way wheel assembly 305 of the circuit board bracket 3. The one-way wheel detection device 11 includes a chain 1101 arranged parallel to the sliding direction of the slide rail 2, which is used for the one-way wheel assembly 305 to pass through. Typically, the circuit board bracket 3 is equipped with a one-way wheel assembly 305 to ensure that the circuit board bracket 3 moves in a specified direction on the processing guide rail and avoids reverse displacement. Therefore, in this embodiment, a one-way wheel detection device 11 is set to perform functional testing on its one-way wheel assembly 305. In the actual testing process, the circuit board bracket 3 is slid along the slide rail 2. At this time, the one-way wheel assembly 305 of the circuit board bracket 3 will contact the chain 1101 and move on the chain 1101. By observing the movement between the one-way wheel assembly 305 and the chain 1101, the functional status of the one-way wheel assembly 305 can be determined. Specifically, if the one-way wheel assembly 305 jumps up at the chain 1101, it means that the one-way wheel assembly 305 is stuck by the chain 1101 and needs to be replaced; if it does not jump up, move the circuit board bracket 3 in the opposite direction. If the circuit board bracket 3 cannot be moved, it means that the one-way wheel assembly 305 is functioning normally, and vice versa.
