[0002] The purpose of designing the light guide column on the SSD is mainly to make the LED lights on the PCB circuit board transmit light more evenly, to avoid the situation where the light is bright and the surrounding is dark. At the same time, due to the large number of components distributed on the PCB circuit board, the lamp beads can only be installed on the PCB sideways, and the light guide column turns and refracts to achieve a uniform light transmission effect. In addition, the light guide column can also allow lights of various colors to form a variety of color lighting effects through different light guide beads, adding visual beauty to the SSD. In the design of the SSD, the light guide column plays a key role, not only beautifying the product, but also improving the user experience.

[0003] During the inspection of incoming hard disks, server manufacturers will inspect whether the light guide column on the hard disk bracket can guide light and the transparency of the light guide column. Existing light guide detection equipment includes a fixture, a detection light source and a light detection module. A light inlet channel is formed in the fixture, and the opening of the light inlet channel exposed in the fixture is directly opposite to the installation position of the light guide column; the detection light source is set above the fixture, and the light detection module is used to judge the assembly status of the light guide column according to the luminous flux value of the detection light.

[0004] However, in actual production, after placing the hard disk tray on the fixture, the operator needs to manually adjust the hard disk tray so that the light guide is aligned with the light detection module. In addition, due to the irregular shape of the hard disk tray, the accuracy and efficiency of manual positioning are low, so there is room for improvement. Summary of the invention

After the test is completed, the first positioning block and the second positioning block simultaneously move displacement B toward the direction away from the jig, relax the hard disk bracket, and the first flap assembly and the second flap assembly are still in a closed state. If the test result shows that the product is qualified, the second positioning block moves displacement A toward the direction away from the jig, the second flap assembly opens, and the hard disk bracket enters the collection box through the second notch and the third notch. If the product is unqualified, the first positioning block moves displacement A toward the direction away from the jig, the first flap assembly opens, and the hard disk bracket enters the defective product recovery box through the first notch and the third notch. By setting the first flap assembly and the second flap assembly, automatic material collection can be realized, and automatic material separation can be realized through the control of the PLC controller, and qualified products and unqualified products can be collected separately, saving manpower and improving efficiency and accuracy. At the same time, the first flap assembly and the second flap assembly are respectively linked with the first positioning block and the second positioning block, and are powered by the first positioning cylinder and the second positioning cylinder, thereby reducing costs; 3.

The hard disk bracket slides down along the top wall of the second flap to the bottom plate, and then flips in the direction to pass through the gap between the top plate and the bottom plate, and falls into the collection box along the top wall of the bottom plate, buffering the falling of the hard disk bracket.

The hard disk bracket includes two brackets intersecting at right angles, and the light guide column is embedded in the bracket located at the upper part, and the first end face 141 and the second end face 142 match the two right-angle side walls of the hard disk bracket. A detection light source 23 is installed on the fixture 14, and the shell of the detection light source 23 is fixedly connected to the side wall of the fixture 14 by bolts, and the detection light source 23 is located on the left side of the first end face 141. A first positioning cylinder 21 opposite to the first end face 141 and a second positioning cylinder 22 opposite to the second end face 142 are provided on the workbench 1, and the shells of the first positioning cylinder 21 and the second positioning cylinder 22 are fixed on the workbench 1 by bolts. A first positioning block 211 is installed on the cylinder shaft of the first positioning cylinder 21 by bolts, a second positioning block 221 is installed on the cylinder shaft of the second positioning cylinder 22 by bolts, a light detection module 24 is installed on the second positioning block 221, a housing of the light source detection module is fixedly connected to the end wall of the second positioning block 221 close to the first positioning cylinder 21 by bolts, and the detection light source 23 and the light source detection module are respectively located at both ends of the first end surface 141. A PLC controller is provided on the workbench 1, the first positioning cylinder 21 and the second positioning cylinder 22 are electrically connected to the PLC controller, and the detection light source 23 and the light detection module 24 are also electrically connected to the PLC controller.

[0037] The operator places the hard disk bracket against the first end face 141 and the second end face 142 of the fixture 14, and the PLC controller controls the first positioning cylinder 21 and the second positioning cylinder 22 to start. The first positioning cylinder 21 drives the first positioning block 211 to press the hard disk bracket against the first end face 141, and the second positioning cylinder 22 drives the second positioning block 221 to press the hard disk bracket against the second end face 142. At this time, the detection light source 23 is aligned with the left end of the light guide column, and the light source detection module is aligned with the right end of the light guide column. The detection light source 23, the light guide column and the light source detection module are located on the same straight line. The PLC controller controls the detection light source 23 and the light detection module 24 to start detection, and transmits the detection results back to the PLC controller. The automatic positioning and detection of the hard disk bracket are realized, and the accuracy of positioning and the efficiency of detection are improved.

[0038] Reference Figure 3The first positioning block 211 is provided with two positioning pins 25, which are integrally formed on the side wall of the first positioning block 211 close to the first end face 141, and the two positioning pins 25 are arranged along the diagonal of the side wall of the first positioning block 211. The positioning pins 25 match the through holes provided on the hard disk bracket, and the front end of the positioning pins 25 away from the first positioning block 211 is arranged in a conical shape.

[0039] When the first positioning cylinder 21 drives the first positioning block 211 to approach the first end surface 141, the first positioning block 211 drives the tip of the positioning pin 25 to be inserted into the through hole of the hard disk bracket, and the two positioning pins 25 arranged along the diagonal line can further improve the accuracy of the hard disk bracket positioning. When the first positioning block 211 presses the hard disk bracket against the first end surface 141, the travel switch 27 is triggered, and the travel switch 27 transmits a signal to the PLC controller, and the PLC controller controls the first positioning cylinder 21 and the second positioning cylinder 22 to stop moving.

[0040] Reference Figure 3 Two light shielding plates 26 are arranged on the first positioning block 211, and the two light shielding plates 26 are respectively located at both ends of the length direction of the first positioning block 211. The light shielding plates 26 are installed on the top wall of the first positioning block 211, and the edge of the light shielding plates 26 protrudes from the side wall of the first positioning block 211 close to the first end surface 141, and the two light shielding plates 26 can cover the detection light source 23 and the light detection module 24 respectively.

[0041] When the first positioning block 211 and the second positioning block 221 press the hard disk bracket tightly, the light shielding plate 26 on the left side covers the hard disk bracket above the contact position between the detection light source 23 and the light guide column, and the light shielding plate 26 on the right side covers the hard disk bracket above the contact position between the light detection module 24 and the light guide column. This prevents external light sources from affecting the detection results; the light shielding plate 26 will not collide with the detection light source 23 and the light detection module 24 when moving.

[0042] Reference Figure 2 and Figure 4 The workbench 1 is provided with a first notch 11, a second notch 12 and a third notch 13. The first notch 11 is located between the first end surface 141 and the first positioning cylinder 21, and the second notch 12 is located between the second positioning cylinder 22. The end of the first notch 11 close to the second positioning cylinder 22 is connected to the third notch 13, and the end of the second notch 12 close to the first positioning cylinder 21 is connected to the third notch 13. The projection of the hard disk bracket falls within the range of the first notch 11, the second notch 12 and the third notch 13, and the center of gravity of the hard disk bracket is at the third notch 13.

[0043] Reference Figure 2 A collection box 5 and a defective product recovery box 6 are provided under the workbench 1, and the collection box 5 and the defective product recovery box 6 are placed on the ground. The collection box 5 is located below the second notch 12 and the third notch 13, and the defective product recovery box 6 is located on the side of the first notch 11 away from the fixture 14.

[0044] Reference Figure 5 and Figure 6 The first notch 11 and the second notch 12 are respectively provided with a first flap assembly 3 and a second flap assembly 4. The first flap assembly 3 cooperates with the first positioning block 211, and the second flap assembly 4 cooperates with the second positioning block 221. The first flap assembly 3 and the second flap assembly 4 both include an open state and a closed state.

[0045] When the hard disk tray is not placed, the first positioning block 211 and the second positioning block 221 are away from the first end face 141 and the second end face 142. At this time, the first flap assembly 3 and the second flap assembly 4 are both in an open state, and the first notch 11 and the second notch 12 are exposed. The PLC controller drives the first positioning block 211 and the second positioning block 221 to move displacement A toward the fixture 14 respectively by controlling the first positioning cylinder 21 and the second positioning cylinder 22 to close the first flap assembly 3 and the second flap assembly 4. The operator places the hard disk tray, and the first flap assembly 3 and the second flap assembly 4 jointly support the weight of the hard disk tray. The first positioning block 211 and the second positioning block 221 continue to move displacement B in the direction close to the fixture 14 to press the hard disk tray tightly. During this process, the first flap assembly 3 and the second flap assembly 4 remain in a closed state.

[0046] After the test is completed, the first positioning block 211 and the second positioning block 221 simultaneously move a displacement B in the direction away from the fixture 14, loosening the hard disk bracket, and the first flap assembly 3 and the second flap assembly 4 remain in the closed state. If the test result shows that the product is qualified, the PLC controller controls the second positioning cylinder 22 to drive the second positioning block 221 to move a displacement A in the direction away from the fixture 14, and the second flap assembly 4 opens to expose the second notch 12. At this time, only the first flap assembly 3 supports the weight of the hard disk bracket, and the hard disk bracket tilts toward the second notch 12 and the third notch 13, and enters the collection box 5 through the second notch 12 and the third notch 13.

[0047] If the product is unqualified, the PLC controller controls the first positioning cylinder 21 to drive the first positioning block 211 to move the displacement A in the direction away from the fixture 14, and the first flap assembly 3 opens to expose the first notch 11. At this time, only the second flap assembly 4 supports the weight of the hard disk bracket, and the hard disk bracket pours toward the first notch 11 and the third notch 13, and enters the defective product recovery box 6 through the first notch 11 and the third notch 13. After the blanking is completed, the first positioning block 211 and the second positioning block 221 are reset, and the first flap assembly 3 and the second flap assembly 4 are closed, waiting for the operator to place the next hard disk bracket to be tested.

[0048] By setting the first flap assembly 3 and the second flap assembly 4, automatic material collection can be realized, and automatic material separation can be realized through the control of the PLC controller, and qualified products and unqualified products can be collected separately, saving manpower and improving efficiency and accuracy. At the same time, the first flap assembly 3 and the second flap assembly 4 are respectively linked with the first positioning block 211 and the second positioning block 221, and the power is provided by the first positioning cylinder 21 and the second positioning cylinder 22, which reduces the cost.

Two folding members 15 are installed on the bottom wall of the workbench 1. The two folding members 15 are respectively located below the first end surface 141 and the second end surface 142, and are respectively arranged along the length direction of the first flap 31 and the second flap 41. One free end of the folding member 15 is connected to the bottom wall of the workbench 1 by bolts, and the other free end is connected to the top wall of the first flap 31 or the second flap 41 by bolts. The first flap 31 and the second flap 41 can rotate along the rotating shaft of the folding member 15, and the free end of the first flap 31 is arranged toward the first positioning cylinder 21, and the free end of the second flap 41 is arranged toward the second positioning cylinder 22.

[0050] A first support plate 311 is integrally formed on the bottom wall of the first flap 31 away from the folding member 15. The first support plate 311 intersects the first flap 31 at a right angle and is an L-shaped plate. One end of the first driving member is connected to the bottom end of the first support plate 311, and the other end is connected to the first positioning block 211. A second support plate 411 is installed on the bottom wall of the second flap 41 away from the folding member 15. One end of the second driving member is connected to the bottom end of the second support plate 411, and the other end is connected to the second positioning block 221.

[0051] The hard disk tray slides down along the first flap 31 or the second flap 41 , and the first flap 31 and the second flap 41 guide the qualified products and the unqualified products to two directions to avoid confusion.

[0052] Reference Figure 7The first driving member includes a rotating drum 32. A bracket 37 is installed on the top wall of the workbench 1 near the first positioning block 211. The rotating drum 32 is arranged in the bracket 37 along the vertical direction and is rotatably connected with the bracket 37 through a rotating shaft. The rotating shaft at the bottom end of the rotating drum 32 extends downward through the bracket 37. A gear 33 is fixedly installed at the bottom end of the rotating shaft. The gear 33 rotates synchronously with the rotating drum 32. A rack 34 is installed on the side wall of the first positioning block 211 near the gear 33 through bolts, and the rack 34 is always meshed with the gear 33. A hole is opened on the bracket 37 along the vertical direction, and a driving rod 35 is inserted into the hole. The driving rod 35 and the bracket 37 are slidably matched. A driving groove 321 is opened on the peripheral wall of the rotating drum 32. A short column 38 is installed on the side wall of the driving rod 35 facing the rotating drum 32 through bolts. The end of the short column 38 away from the driving rod 35 is inserted in the driving groove 321, and the short column 38 is slidably matched with the inner wall of the driving groove 321. The bottom end of the driving rod 35 extends downward through the bracket 37, and the bottom end of the driving rod 35 is bolted with a rotating seat 39. The rotating seat 39 is connected with a connecting rod 36, one end of the connecting rod 36 is rotatably connected to the driving rod 35 through the rotating seat 39, and the end of the connecting rod 36 away from the rotating seat 39 is rotatably connected to the first support plate 311 through a rotating shaft.

[0053] Reference Figure 7 The driving groove 321 includes a straight section 322 and an inclined section 323 . The straight section 322 is arranged at the top of the rotating drum 32 . The straight section 322 and the inclined section 323 are smoothly connected.

[0054] When the first positioning block 211 is away from the first end face 141, the gear 33 is located at the end of the rack 34 close to the fixture 14, the short column 38 is located at the bottom end of the rotating drum 32, and the rotating seat 39 is located at its lowest point, and the end of the first flap 31 away from the folding member 15 tilts downward. The first positioning block 211 moves a displacement A in the direction close to the first end face 141, and the first positioning block 211 drives the rack 34 to move toward the first end face 141 relative to the gear 33. The gear 33 is restricted by the bracket 37 and rotates clockwise under the action of the rack 34. The rotation of the gear 33 drives the rotating drum 32 to rotate clockwise. The rotation of the rotating drum 32 forces the short column 38 to move from the bottom end of the inclined section 323 along the inner wall of the driving groove 321 to the top end of the inclined section 323, that is, the connection between the inclined section 323 and the straight section 322; the driving rod 35 is restricted by the bracket 37, and the short column 38 drives the driving rod 35 to move vertically upward. The driving rod 35 drives the rotating seat 39 to move vertically upward to its highest point, the rotating seat 39 drives the left end of the connecting rod 36 to move upward, and the right end of the connecting rod 36 drives the first flap 31 to rotate upward through the first support plate 311 until the connecting rod 36 is vertical and the first flap 31 is horizontal, and the first flap 31 covers the first notch 11.

[0055] The first positioning block 211 continues to move toward the first end surface 141 by a displacement B, so that the positioning pin 25 positions the hard disk bracket. The gear 33 continues to drive the rotating drum 32 to rotate clockwise, and the short column 38 moves in the straight section 322. The driving rod 35, the rotating seat 39, the connecting rod 36 and the first support plate 311 all remain stationary, and the first flap 31 always covers the first notch 11.

[0056] After the detection is completed, the first positioning block 211 moves a displacement B in the direction away from the first end face 141, so that the positioning pin 25 is separated from the hard disk bracket. The gear 33 drives the rotating drum 32 to rotate counterclockwise, and the short column 38 moves from the straight section 322 to the intersection with the inclined section 323. The first positioning block 211 continues to move a displacement A in the direction away from the first end face 141, and the gear 33 drives the rotating drum 32 to continue to rotate counterclockwise. The short column 38 moves from the top of the inclined section 323 along the inner wall of the driving groove 321 to the bottom of the inclined section 323, and the driving rod 35 and the rotating seat 39 move downward. Driven by the connecting rod 36, the first flap 31 rotates downward to expose the first notch 11. The hard disk bracket tilts downward along the top wall of the first flap 31 and slides into the defective product recovery box 6.

[0057] The second driving member has the same structure as the first driving member, and the second flap 41 is linked with the second positioning block 221 through the second driving member.

[0058] Reference Figure 2 and Figure 6 The defective product recovery box 6 is located on the side of the first notch 11 away from the fixture 14. The collection box 5 is arranged directly below the second notch 12. The volume of the collection box 5 is larger than that of the defective product recovery box 6, so as to facilitate the collection of qualified products. A tipping bucket 7 is arranged at the top of the collection box 5.

[0059] Reference Figure 6 The tipping bucket 7 includes a connecting shaft 72. Two downward vertical rods 76 are installed on the bottom wall of the workbench 1. A rotating sleeve 77 is installed at the bottom end of the vertical rod 76. The connecting shaft 72 is rotatably connected between the two rotating sleeves 77. The length direction of the connecting shaft 72 is parallel to the length direction of the second flap 41. A top plate 71 is installed on the outer peripheral wall of the connecting shaft 72 by bolts. A contact rod 78 is integrally formed at the top of the top plate 71. The diameter of the contact rod 78 is greater than the thickness of the top plate 71. The outer peripheral wall of the contact rod 78 can contact the bottom wall of the second flap 41.

[0060] Two support rods 73 are installed on the side of the outer peripheral wall of the connecting shaft 72 away from the top plate 71, and the two support rods 73 are located at both ends of the connecting shaft 72. A bottom plate 74 is installed at the bottom ends of the two support rods 73, and the bottom ends of the two support rods 73 are connected to the middle of the bottom plate 74 by bolts. The top plate 71 and the bottom plate 74 are perpendicular to each other. The height of the support rod 73 is greater than the thickness of the hard disk bracket, and the gap between the top plate 71 and the bottom plate 74 is enough for the hard disk bracket to pass through. The bottom plate 74 is located above the collection box 5, and an inclined plate 75 is installed on the side wall of the bottom plate 74 close to the fixture 14 by bolts, and the end of the inclined plate 75 away from the bottom plate 74 is tilted downward. A counterweight block 79 is installed on the bottom wall of the bottom plate 74 away from the inclined plate 75 by bolts, so that the weight on the bottom plate 74 on both sides of the support rods 73 is close.

[0061] When the second flap 41 covers the second notch 12, the second flap 41 does not contact the contact rod 78, the bottom plate 74 is in a horizontal state under the action of gravity, and the bottom plate 74 and the inclined plate 75 can cover most of the area above the collection box 5, reducing the possibility of unqualified products entering the collection box 5. When the second flap 41 rotates downward, the bottom wall of the second flap 41 contacts the outer peripheral wall of the contact rod 78, and drives the top plate 71 and the connecting shaft 72 to rotate counterclockwise, and the support rod 73 drives the bottom plate 74 to rotate upward counterclockwise, so that the bottom plate 74 tilts. The hard disk bracket slides down along the top wall of the second flap 41 to the bottom plate 74, and then flips through the gap between the top plate 71 and the bottom plate 74, and falls into the collection box 5 along the top wall of the bottom plate 74. The hard disk bracket falls into the collection box 5 after being buffered by the bottom plate 74, reducing the damage to the hard disk bracket caused by excessive impact force of falling. The collecting box 5 is arranged below the workbench 1, which can avoid the collecting box 5 from being damaged by collision with other equipment during production, and can also increase the volume of the collecting box 5 as much as possible to improve practicality.

[0062] The implementation principle of the server hard disk optical band continuity test device of the embodiment of the present application is as follows: the PLC controller drives the first positioning block 211 and the second positioning block 221 to move the displacement A close to the fixture 14 through the first positioning cylinder 21 and the second positioning cylinder 22, and the first flap 31 and the second flap 41 cover the first notch 11 and the second notch 12 respectively; then the first positioning block 211 and the second positioning block 221 clamp the hard disk bracket, and the detection light source 23 and the light detection module 24 are aligned with the light guide column for detection. After the detection is completed, the first positioning block 211 and the second positioning block 221 move the displacement A away from the fixture 14 to release the hard disk bracket. The PLC controller controls the first flap 31 or the second flap 41 to open according to the detection result, so that the qualified products fall into the collection box 5 through the tipping bucket 7, and the unqualified products fall into the defective product recovery box 6. The automatic positioning and detection of the special-shaped hard disk bracket are realized, and the accuracy and efficiency of positioning and detection are improved.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
