Description

Technical Field

[0001] The utility model relates to the technical field of substrate function detection equipment, in particular to a substrate detection device and a temperature control box. Background Art

[0002] After production, the substrate needs to undergo functional testing. This involves communicating with the substrate through a control cabinet, exchanging information with the substrate, and completing the test. In some cases, the substrate needs to be placed in a temperature-controlled chamber to perform functional testing in high and low temperature environments.

[0003] See attached Figure 1 As shown, the substrate 2 is usually placed on the jig 1, and the jig 1 is provided with a probe that is conductive with the substrate, and a first plug 11 is fixed on the jig. The control cabinet and the jig 1 need to be connected through a detection device, and the handling device places the jig on the detection device. The detection device needs to be able to fix the jig and communicate with the first connector. When the substrate detection device is plugged into the first plug, it can detect the substrate. After the detection is completed, the substrate detection device needs to be separated from the first plug to facilitate the handling device to carry the jig away from the detection device. However, when the detection device is separated from the first plug, it often sticks to the first plug, causing the movement of the jig, which interferes with the subsequent handling of the handling device. Utility Model Content

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a substrate detection device and a temperature control box, which can press the jig when the first plug and the second plug are separated to prevent the jig from shaking or deflecting.

[0005] In order to achieve the above objectives, the technical solution adopted by the present invention is: a substrate detection device, wherein the substrate is fixed on a fixture, and a first plug vertically upward is fixed on the fixture, and the detection device includes:

[0006] A placement table, the placement table comprising a placement surface for carrying the jig;

[0007] a second plug, the second plug being located directly above the first plug and being movable up and down to switch between a disconnected position and a plugged position;

[0008] A pressing assembly is located above the jig, and the pressing assembly includes a guide rod, a pressure rod and a spring. The guide rod rises and falls synchronously with the second plug. The pressure rod is inserted into the guide rod and can move up and down along the axis of the guide rod. The spring is sleeved on the part of the pressure rod that passes through the guide rod downward. When the second plug is plugged into the first plug, the pressure rod abuts against the jig and compresses the spring.

[0009] The beneficial effects of the present invention are:

[0010] The placement table is used to place the fixture. The second plug is connected or separated with the first plug during the lifting process to realize the connection and disconnection between the control cabinet and the substrate, thereby realizing the performance detection of the substrate.

[0011] When the first and second plugs are connected, the pressing assembly compresses the spring, which continuously accumulates force and presses the jig downward. When the first and second plugs are separated, the spring remains compressed, pushing the pressure rod downward to press the jig. At this point, the spring's pressure is greater than the adhesive force between the first and second plugs, preventing the jig from moving upward due to the second plug, thus improving its stability and preventing movement.

[0012] Furthermore, the fixture is fixed with an abutment block corresponding to the pressing assembly. When the second plug is in the disengaged position, the vertical distance between the lower end surface of the pressure rod and the upper end surface of the abutment block is smaller than the vertical distance between the first plug and the second plug. This ensures that when the abutment block and the pressure rod are in contact, the first and second plugs are not plugged in. At this time, the pressure rod will move upward relative to the guide rod to continuously compress the spring.

[0013] Furthermore, two pressing assemblies are provided, and the two pressing assemblies are symmetrically arranged relative to the second plug.

[0014] Furthermore, an upper boss and a lower boss extend outwardly from the outer wall of the pressure rod, the upper boss is located above the guide rod and can abut against the guide rod, and the lower boss is located below the guide rod and abuts against the lower end of the spring.

[0015] The upper boss plays a limiting role, limiting the maximum downward movement of the pressure rod relative to the guide rod; the lower boss positions the spring, and the spring is located between the lower boss and the guide rod.

[0016] Furthermore, the guide rod and the second plug are fixed together on a lifting plate, and the lifting plate is lifted and lowered by a lifting driving member, thereby achieving synchronous lifting of the guide rod and the second plug.

[0017] Furthermore, the placement table is provided with a positioning post extending upward from the placement surface, and the fixture is provided with a positioning hole for the positioning post to be inserted into. The positioning post is inserted into the positioning hole to position the fixture in the horizontal direction.

[0018] Furthermore, the placement table is also provided with two guide parts extending upward from the placement surface, the two guide parts are located on both sides of the jig, and the opposite surfaces of the two guide parts include an inclined part, and the inclined parts of the two guide parts are inclined from top to bottom toward the side close to each other.

[0019] The two guides' inclined sections form a flared structure, allowing the jig to be lowered onto the placement surface from top to bottom. The inclined sections act as guides, facilitating entry. Even if the jig deviates during descent, the inclined sections guide it to its intended position.

[0020] Specifically, the lifting drive member is fixed to a bracket, a linear bearing is fixed to the bracket, and a guide rod passing through the linear bearing is fixed to the lifting plate. The guide rod and the linear bearing cooperate to guide the movement of the lifting plate.

[0021] Furthermore, the detection device further includes a position sensor, and the position sensor is communicatively connected to the lifting drive component.

[0022] The utility model also discloses a temperature control box, which includes a plurality of test cavities, and the above-mentioned detection device is fixed in each of the test cavities. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0040] Example 1

[0041] See attached Figure 1 and attached Figure 2 As shown, a substrate 2 detection device of the present invention is provided, wherein the substrate 2 is fixed on a jig 1 , a first plug 11 pointing vertically upward is fixed on the jig 1 , and the detection device includes a placement table 3 , a second plug 4 and a pressing component 5 .

[0042] See attached Figure 3 As shown, the placement table 3 includes a placement surface for supporting the jig 1; the second plug 4 is located directly above the first plug 11, and the second plug 4 can move up and down to switch between a separation position and a plug-in position. The pressing assembly 5 is located above the jig 1, and the pressing assembly 5 includes a guide rod 51, a pressure rod 52, and a spring 53. The guide rod 51 rises and falls synchronously with the second plug 4. The pressure rod 52 is inserted into the guide rod 51 and can move up and down along the axis of the guide rod 51. The spring 53 is sleeved on the portion of the pressure rod 52 that extends downward from the guide rod 51. When the second plug 4 is plugged into the first plug 11, the pressure rod 52 abuts against the jig 1 and compresses the spring 53.

[0043] See attached Figure 2 As shown, the second plug 4 is at the separation position, that is, the second plug 4 is in the initial state. When the second plug 4 moves downward to be plugged with the first plug 11, the second plug 4 is in the plugging position.

[0044] In this embodiment, the second plug 4 is connected to an external control cabinet (not shown in the figure) through a cable, and the placement table 3 is used to place the fixture 1. The second plug 4 is connected or separated with the first plug 11 during the lifting process to realize the connection and disconnection between the control cabinet and the substrate 2, thereby realizing the performance detection of the substrate 2.

[0045] Because the first plug 11 and the second plug 4 have adhesion at the moment of separation, the second plug 4 may drive the first plug 11 (jig 1) to move upward, causing the jig 1 to deflect and shake. Therefore, a pressing component 5 is provided in the present application. When the first plug 11 and the second plug 4 are plugged in, the pressing component 5 compresses the spring 53. The spring 53 continuously accumulates force and presses the jig 1 downward. When the first plug 11 and the second plug 4 are separated, the spring 53 is still in a compressed state, pushing the pressure rod 52 to press the jig 1 downward. At this time, the pressure F provided by the spring 53 is greater than the adhesion between the first plug 11 and the second plug 4. The jig 1 will not move upward under the drive of the second plug 4, thereby improving the stability of the jig 1 and preventing the jig 1 from moving.

[0046] In one embodiment, see the attached Figure 1 and attached Figure 4 As shown, the fixture 1 is fixed with an abutment block 12 corresponding to the pressing assembly 5. When the second plug 4 is in the separated position, the vertical distance d1 from the lower end surface of the pressing rod 52 to the upper end surface of the abutment block 12 is smaller than the vertical distance d2 from the first plug 11 to the second plug 4.

[0047] The separation position is the initial state. At this moment, the pressure rod 52 does not abut against the abutment block 12. The pressure rod 52 is downward relative to the guide rod 51 by relying on its own gravity. The spring 53 is in a natural state or has slight compression. The lower end of the pressure rod 52 is at the longest distance from the guide rod 51 at this moment. When the first plug 11 and the second plug 4 are just separated, the spring 53 needs to remain in a compressed state, that is, it is required that the pressure rod 52 moves upward relative to the guide rod 51 at this moment. Therefore, the vertical distance d1 from the lower end face of the pressure rod 52 to the upper end face of the abutment block 12 is less than the vertical distance d2 from the first plug 11 to the second plug 4. In this way, when the abutment block 12 and the pressure rod 52 are in contact, the first plug 11 and the second plug 4 are not connected. At this moment, the pressure rod 52 can move upward relative to the guide rod 51 to continuously compress the spring 53.

[0048] In one embodiment, two pressing assemblies 5 are provided, and the two pressing assemblies 5 are symmetrically arranged relative to the second plug 4. When the two pressing assemblies press down on the fixture 1, the pressure is more uniform. Of course, in one embodiment, one, three, or more pressing assemblies 5 can also be provided, depending on the structure of the fixture 1.

[0049] In one embodiment, see the attached Figure 3 As shown, an upper boss 521 extends outward from the outer wall of the pressure rod 52. The upper boss 521 is located above the guide rod 51 and can abut against the guide rod 51. When the upper boss 521 abuts against the guide rod 51, the pressure rod 52 is at the extreme position where it can move downward relative to the guide rod 51. The upper boss 521 acts as a limiter, limiting the maximum downward movement of the pressure rod 52 relative to the guide rod 51.

[0050] The outer wall of the pressure rod 52 extends outwardly to form a lower boss 522, which is located below the guide rod 51 and abuts against the lower end of the spring 53. The upper end of the spring 53 abuts against the lower end of the guide rod 51. The lower boss 522 positions the spring 53, and the spring 53 is located between the lower boss 522 and the guide rod 51.

[0051] In one embodiment, see the attached Figure 2 and attached Figure 3 As shown, the guide rod 51 and the second plug 4 are fixed together on a lifting plate 6, thereby achieving synchronous lifting and lowering of the guide rod 51 and the second plug 4. The lifting plate 6 is lifted and lowered by a lifting drive 61, which can be a cylinder, directly pushing the lifting plate 6 to perform linear reciprocating movement.

[0052] See attached Figure 2 and attached Figure 3 As shown, the lifting drive 61 is fixed to a bracket 62, a linear bearing 63 is fixed to the bracket 62, and a guide rod 64 is fixed to the lifting plate 6, which passes through the linear bearing 63. The bracket 62 is used to fix the lifting drive 61, and the linear bearing 63 cooperates with the guide rod to provide guidance for the lifting and lowering of the lifting plate 6.

[0053] In this embodiment, two guide rods 64 are provided along the length direction of the lifting plate 6 .

[0054] See attached Figure 3 As shown, the bracket 62 is fixed on a base plate 8 , the stand is a door-shaped stand, and the placement table 3 is also fixed on the base plate 8 .

[0055] In one embodiment, see the attached Figure 3 As shown, the placement table 3 is provided with a positioning post 32 extending upward from the placement surface 31, and the fixture 1 is provided with a positioning hole for the positioning post 32 to be inserted. When the positioning post 32 is inserted into the positioning hole, the position of the fixture 1 is positioned to prevent the fixture 1 from moving during testing.

[0056] The number and positions of the positioning posts 32 are set according to actual needs. In this embodiment, two positioning posts 32 are provided.

[0057] In one embodiment, the placement table 3 is further provided with two guide portions 33 extending upward from the placement surface 31, and the two guide portions 33 are located on both sides of the jig 1. The jig 1 is confined between the two guide portions 33, and the guide portions 33 further define the position of the jig 1.

[0058] See attached Figure 5As shown, the opposing surfaces of the two guides 33 include an inclined portion 331. The inclined portions 331 of the two guides 33 are inclined from top to bottom, toward each other. These inclined portions 331 form a flared structure. When the jig 1 is placed from top to bottom on the placement surface 31, the inclined portions 331 serve as guides, facilitating its entry. Even if the jig 1 deviates during its descent, the inclined portions 331 will guide it straight, ensuring it remains in its intended position.

[0059] The robot moves jig 1 onto the placement table 3. The placement table 3 has a clearance slot 34 extending downward from the placement surface 31. The robot leaves the testing device through the clearance slot 34. The robot moves jig 1 to the loading position between the placement table 3 and the second plug 4. The robot then moves downward, placing the jig 1 on the placement surface 31. The robot continues downward, separating from the jig 1 and moving into the clearance slot 34. Finally, the robot extends horizontally from the clearance slot 34 and leaves the placement table 3.

[0060] See attached Figure 2 and attached Figure 3 As shown, the detection device also includes a position sensor 7, which is in communication with the lifting drive 61. When the position sensor 7 senses that the fixture 1 is in place, it transmits information to the lifting drive 61, which then pushes the second plug 4 downward to plug into the first plug 11.

[0061] In one embodiment, see the attached Figure 3 and attached Figure 4 As shown, the detection device also includes a plug-in assembly 9, which is located on one side of the placement table 3. The plug-in assembly 9 includes a horizontal drive member 91 and a third plug 92. The horizontal drive member 91 is fixed on the base plate 8. The third plug 92 is connected to the horizontal drive member 91 and moves in the horizontal direction under the drive of the horizontal drive member 91. A fourth plug that can be plugged into the third plug 92 is provided on the side of the jig 1. When the first plug 11 and the second plug 4 are plugged in, the third plug 92 must also be inserted into the fourth plug. Because the horizontal position of the jig 1 is limited by the fixed column, when the third plug 92 and the fourth plug are separated, it will not cause the jig 1 to shift in the horizontal direction.

[0062] Example 2

[0063] See attached Figure 6 As shown, a temperature control box of the present invention includes multiple test cavities, and the detection device of Example 1 is fixed in each of the test cavities.

[0064] The temperature control box can perform functional tests on the substrate 2 while performing environmental tests on the substrate 2 .

[0065] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
