Description

Technical Field

[0001] This utility model relates to an adaptive lifting fixture for an LED integrator tester. Background Technology

[0002] An LED integrating tester is a comprehensive testing system used to measure the photoelectric and color performance of LED light sources. It is widely used in LED production, quality inspection, and R&D. The fixture used in an LED integrating tester is a clamp used to fix the LED chip and ensure its electrical connection to the testing system. It mainly includes a housing and conductive pins. The conductive pins are located inside the housing and partially protrude from the top of the housing for electrical connection with the LED chip. Because the length of the conductive pin protruding from the top of the housing is uniform, it cannot accommodate LED chips of different thicknesses, resulting in significant limitations in its use. Utility Model Content

[0003] The purpose of this invention is to provide an adaptive lifting fixture for an LED integrator tester, so as to solve the problem that the existing fixtures for LED integrator testers cannot be adapted to LED chips of different thicknesses and have great limitations in use.

[0004] This utility model is achieved through the following technical solution:

[0005] An adaptive lifting fixture for an LED integration tester includes a housing, a lifting base, and a drive base. The housing has a cavity for accommodating the lifting base and the drive base. The lifting base is provided with a conductive needle and a guide rod. The drive base is provided with a guide groove that slides with the guide rod. The drive base can move left and right relative to the housing. When the drive base moves left and right, the guide rod moves along the guide groove, causing the lifting base to move up and down relative to the housing, so that the conductive needle extends out or retracts into the housing.

[0006] Furthermore, the outer casing has a top through hole and a side through hole communicating with the accommodating cavity. The top through hole is located at the top of the outer casing, and the side through hole is located on the periphery of the outer casing. The drive seat has an outward push block. When the drive seat moves left and right, the outward push block extends out of the side through hole or retracts into the outer casing. When the lifting seat moves up and down, the conductive needle extends out of the top through hole or retracts into the outer casing.

[0007] Furthermore, the guide groove has at least an inclined groove that is inclined from bottom to top in a direction away from the push block.

[0008] Furthermore, the guide groove also has a horizontal groove that extends horizontally from the lower end of the inclined groove toward the push block.

[0009] Furthermore, the angle between the inclined groove and the horizontal plane ranges from 20° to 40°.

[0010] Furthermore, the direction in which the push block retracts into the housing is defined as the first direction. The drive seat also has an inner abutment block, which is located on the side of the lifting seat opposite to the push block. A stop block is provided in the accommodating cavity. When the conductive needle is fully retracted into the housing, the inner abutment block abuts against the stop block to restrict the movement of the drive seat in the first direction.

[0011] Furthermore, the direction in which the push block extends out of the housing is defined as the second direction, and an elastic element is provided between the housing and the drive seat, and the drive seat is driven by the elastic element to move in the second direction.

[0012] Furthermore, the drive seat has a clearance hole for the lower end of the lifting seat to be inserted.

[0013] Furthermore, the housing has a first sliding groove that slides in conjunction with the lifting seat, and the lifting seat moves up and down along the first sliding groove; and / or the housing has a second sliding groove that slides in conjunction with the drive seat, and the drive seat moves left and right along the second sliding groove.

[0014] Furthermore, the outer shell has an upper shell and a lower shell, which are arranged vertically to form the accommodating cavity. The upper shell is positioned higher and the lower shell is positioned lower. The top of the upper shell has a top through hole, and the lower periphery has a side through hole. And / or the top of the outer shell has two clamps, which are positioned opposite each other to fix the LED chip. The top of the lifting seat has two guide pin groups, which are located between the two clamps and are positioned front to back. Each guide pin group consists of a number of conductive pins that are spaced apart from each other.

[0015] The advantage of this technical solution is that by configuring a lifting seat and a driving seat inside the housing, a conductive needle and a guide rod are configured on the lifting seat, and a guide groove is configured on the driving seat. When the driving seat moves left and right, the guide rod moves along the guide groove, causing the lifting seat to move up and down, thereby driving the conductive needle to extend or retract into the housing. Therefore, the length of the conductive needle extending out of the housing is adjustable, thus adapting to LED chips of different thicknesses. It has good adaptability and is easy to use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1-6As shown, the adaptive lifting fixture used in this LED integrating tester includes a housing 1, a lifting seat 2, and a drive seat 3. The housing 1 has a receiving cavity 101 for accommodating the lifting seat 2 and the drive seat 3. The lifting seat 2 is provided with a conductive needle 201 and a guide rod 202. The drive seat 3 is provided with a guide groove 301 that slides with the guide rod 202. The guide groove 301 extends left and right, allowing the drive seat 3 to move left and right relative to the housing 1. When the drive seat 3 moves left and right, the guide rod 202 moves along the guide groove 301, causing the lifting seat 2 to move up and down relative to the housing 1, thus extending or retracting the conductive needle 201 into the housing 1. The conductive needle 201 is used to contact and conduct electricity with the electrodes on the bottom surface of the LED chip. This embodiment provides an adaptive lifting fixture for an LED integrating tester to solve the problem that existing fixtures for LED integrating testers cannot adapt to LED chips of different thicknesses and have great limitations in use. It mainly involves configuring a lifting seat 2 and a drive seat 3 inside the housing 1. A conductive needle 201 and a guide rod 202 are configured on the lifting seat 2, and a guide groove 301 is configured on the drive seat 3. When the drive seat 3 moves left and right, the guide rod 202 moves along the guide groove 301, causing the lifting seat 2 to move up and down, thereby driving the conductive needle 201 to extend or retract into the housing 1. Therefore, the length of the conductive needle 201 extending out of the housing 1 is adjustable, thus adapting to LED chips of different thicknesses. It has good adaptability and is easy to use.

[0026] In this embodiment of the invention, the outer shell 1 has a top through hole 102 and a side through hole 103 communicating with the accommodating cavity 101. The top through hole 102 is located at the top of the outer shell 1, and the side through hole 103 is located on the periphery of the outer shell 1. The drive seat 3 has an outward push block 302. When the drive seat 3 moves left and right, the outward push block 302 extends out of or retracts into the outer shell 1 through the side through hole 103. When the drive seat 3 moves left and right, the guide rod 202 moves left and right along the guide groove 301, driving the lifting seat 2 to move up and down, so that the conductive needle 201 extends out of or retracts into the outer shell 1 through the top through hole 102 for the conductive needle 201 to extend out of or retract into the outer shell 1, and the side through hole 103 for the outward push block 302 to extend out of or retract into the outer shell 1 on the periphery of the outer shell 1, so that the drive seat 3 and the lifting seat 2 are assembled compactly and reasonably within the outer shell 1, with smooth movement and good linkage effect.

[0027] In this embodiment of the invention, the guide groove 301 has at least an inclined groove 303, which is inclined from bottom to top in a direction away from the outer push block 302. By configuring the guide groove 301 to have at least an inclined groove 303 that is inclined from bottom to top in a direction away from the outer push block 302, the drive seat 3 can drive the lifting seat 2 to move up and down when it moves left and right. The linkage structure is simple and easy to implement.

[0028] In this embodiment of the invention, the angle between the inclined groove 303 and the horizontal plane ranges from 20° to 40°. Preferably, the angle between the inclined groove 303 and the horizontal plane is 30°.

[0029] In this embodiment of the invention, the guide groove 301 also has a horizontal groove 304, which extends horizontally from the lower end of the inclined groove 303 toward the outward push block 302. By configuring the guide groove 301 to also have a horizontal groove 304 extending horizontally from the lower end of the inclined groove 303 toward the outward push block 302, the conductive needle 201 is retracted into the housing 1, locking the lifting seat 2 in the retracted state.

[0030] In this embodiment of the invention, the direction in which the push block 302 retracts into the outer shell 1 is defined as the first direction. The drive seat 3 also has an inner abutment block 305, which is located on the side of the lifting seat 2 opposite to the push block 302. A stop block 104 is provided in the accommodating cavity 101. When the conductive needle 201 is fully retracted into the outer shell 1, the inner abutment block 305 abuts against the stop block 104 to restrict the movement of the drive seat 3 in the first direction. The above arrangement, by configuring the inner abutment block 305 on the drive seat 3 and the stop block 104 in the accommodating cavity 101, allows the stop block 104 and the inner abutment block 305 to abut against each other when the conductive needle 201 is fully retracted into the outer shell 1, thus limiting the inward movement of the drive seat 3 and preventing the conductive needle 201 from excessively retracting.

[0031] In this embodiment of the invention, the drive base 3 has a clearance hole 306 for the lower end of the lifting base 2 to be inserted. This arrangement, by configuring the clearance hole 306 on the drive base 3 for the lower end of the lifting base 2 to be inserted, ensures stable assembly and smooth movement of the lifting base 2 and the drive base 3.

[0032] In this embodiment of the invention, the outer shell 1 has a first sliding groove 105 that slides with the lifting seat 2, and the lifting seat 2 moves up and down along the first sliding groove 105. This arrangement, by configuring the first sliding groove 105 on the outer shell 1 to slide with the lifting seat 2, ensures stable assembly and smooth movement of the lifting seat 2 and the outer shell 1.

[0033] In this embodiment of the invention, the outer shell 1 has a second sliding groove 109 that slides with the drive seat 3, and the drive seat 3 moves left and right along the second sliding groove 109. This arrangement, by configuring the second sliding groove 109 on the outer shell 1 to slide with the drive seat 3, ensures stable assembly and smooth movement of the drive seat 3 and the outer shell 1.

[0034] In this embodiment of the invention, the direction in which the push block 302 extends out of the outer casing 1 is defined as the second direction. An elastic element (not shown in the figure) is provided between the outer casing 1 and the drive seat 3. The drive seat 3 is driven by the elastic element to move in the second direction, thereby causing the conductive needle 201 to extend out of the top through hole 102. The above arrangement, by configuring an elastic element between the outer casing 1 and the drive seat 3 to drive the drive seat 3 to move in the second direction, allows the conductive needle 201 to move outward and abut against the LED chip under test.

[0035] In this embodiment of the utility model, the outer shell 1 has an upper shell 106 and a lower shell 107. The upper shell 106 and the lower shell 107 are arranged vertically to form an accommodating cavity 101. The upper shell 106 is positioned higher and the lower shell 107 is positioned lower. The top of the upper shell 106 is provided with a top through hole 102, and the lower shell 107 is provided with a side through hole 103 on its periphery. The upper shell 106 and the lower shell 107 are threaded together. By configuring the outer shell 1 as an upper shell 106 and a lower shell 107, with the top through hole 102 located on the top of the upper shell 106 and the side through hole 103 located on the periphery of the lower shell 107, the outer shell 1, the lifting seat 2, and the drive seat 3 are reasonably assembled, quick to assemble and disassemble, and convenient.

[0036] In this embodiment of the invention, the top of the outer casing 1 is provided with two clamps 108, which are positioned opposite each other to fix the LED chip. The top of the lifting base 2 is provided with two guide pin groups 203, which are located between the two clamps 108 and are positioned opposite each other. Each guide pin group 203 is composed of several conductive pins 201 arranged at intervals. The above arrangement, by configuring two opposite clamps 108 on the top of the outer casing 1 for fixing the LED chip, facilitates chip fixing and testing.
