CONCRETE IMPLEMENTATION

[0028] Please refer to Figures 1-5 The embodiment is a universal test fixture 100, which comprises a base 1 and a test plate 2 arranged above the base 1. The test plate 2 is provided with a plurality of receiving grooves 3 for placing products on one side edge thereof. Each receiving groove 3 is provided with a clamping block 4 for clamping the product on the side edge thereof. A push member 6 for simultaneously driving all the clamping blocks 4 away from the receiving grooves 3 to facilitate taking and placing the product is arranged in the height space between the base 1 and the test plate 2. The clamping block 4 is elastically movably arranged on the base 1 through an elastic member. The test plate 2 is provided with a plurality of opening clamp assemblies 8 for driving the clamping block 4 away from the receiving groove 3 to facilitate taking and placing the product. The number of the opening clamp assemblies 8 is consistent with the number of the clamping blocks 4, and each opening clamp assembly 8 acts on the corresponding clamping block 4.

[0029] Since the product 200 includes the test line 201 and the conductive terminal 202 connected at the end of the test line, the number of the conductive terminal 202 on some products 200 is one, while the number of the conductive terminal 202 on some products is multiple, and when testing, the multiple conductive terminals 202 on the same product all need to be tested, and one conductive terminal 202 is placed in each accommodation groove 3. If the product 200 has multiple conductive terminals 202 that need to be tested, all the clamping blocks 4 are driven away from the accommodation groove 3 by the pusher 6 to facilitate the taking and placing of the product, the pusher 6 can simultaneously open the clamping blocks, can simultaneously take out the product, saves the time of taking and placing the product, and improves the testing efficiency. If the product has only one conductive terminal that needs to be tested, any one of the accommodation grooves 3 can be selected, and then the corresponding opening clamping assembly 8 corresponding to the accommodation groove 3 is selected, the opening clamping assembly 8 drives the clamping block 4 away from the accommodation groove 3 to facilitate the taking and placing of the product, so that when the number of the conductive terminals 202 to be tested is less than the number of the set accommodation grooves 3, the corresponding accommodation grooves 3 can be selected according to the number of the conductive terminals 202 to be tested, and the situation of empty running of the multiple clamping blocks 4 can be avoided. Therefore, the scheme can simultaneously open the clamping blocks 4, can simultaneously take out the product, saves the time of taking and placing the product, improves the testing efficiency, and can selectively drive a certain clamping block 4 to open alone, can avoid the situation of empty running of the clamping blocks 4 when the number of the conductive terminals is small, can be suitable for multiple situations, and has good versatility.

[0030] In the embodiment, since the conductive terminals of the multiple products are arranged along an arc, correspondingly, the multiple accommodation grooves 3 on one side edge of the test plate 2 are arranged along an arc, the multiple clamping blocks 4 are arranged along a ring on the right side of the accommodation grooves 3, and the multiple opening clamping assemblies 8 are arranged on the left side of the accommodation grooves 3. The accommodation grooves 3, the clamping blocks 4 and the opening clamping assemblies 8 are all arranged in three and one-to-one correspondence along an arc. In other embodiments, the multiple accommodation grooves 3, the multiple clamping blocks 4 and the multiple opening clamping assemblies 8 can be arranged in other ways, for example, linearly, which is not limited here.

[0031] The conductive terminal is placed into the accommodating groove 3 during testing, and the test wire connected to the conductive terminal also needs to be positioned to ensure the stability of the positioning of the conductive terminal 202. Therefore, a guide positioning groove 41 for positioning the test wire 201 of the product 200 is arranged at the upper end of the clamping block 4. When the conductive terminal 202 is positioned into the accommodating groove 3, the test wire 201 is horizontally positioned into the guide positioning groove 41. The outer periphery of the conductive terminal 202 is in an arc shape. When the conductive terminal 202 is positioned into the accommodating groove 3, the side edge of the clamping block 4 can directly abut against the outer periphery of the product, so that the conductive terminal 202 is limited in the accommodating groove 3. Therefore, the clamping block 4 is provided with a limiting portion 42 abutting against the outer periphery of the conductive terminal 202 of the product at the side close to the accommodating groove 3. The accommodating groove 3 is open at the position towards the limiting portion 42, so that the limiting portion 41 can directly abut against the outer periphery of the conductive terminal 202 of the product. The limiting portion 42 can limit the movement of the conductive terminal 202 in the horizontal direction.

[0032] The clamping block 4 is elastically movably arranged on the base 1 by an elastic member at the side away from the accommodating groove 3. The elastic member is a spring. The spring extends horizontally, and one end of the spring is arranged at one side of the clamping block 4, and the other end of the spring is fixed on the base 1. When the pushing member 6 or the opening clamping assembly 8 acts to push the clamping block 4 to the right side, the clamping block 4 is away from the accommodating groove 3, and the product can be taken out or placed. At this time, the spring is compressed. When the pushing member 6 or the opening clamping assembly 8 is released, the spring stretches to push the clamping block 4 to the side of the accommodating groove 3, so as to clamp the product.

[0033] In the embodiment, the pushing member 6 is a pushing plate. The left end of the pushing member 6 is provided with a pushing handle 61, and the right end of the pushing member 6 is provided with a plurality of pushing portions 62 acting on the clamping block 4. The pushing handle 61 is manually pushed to the right side, so that the pushing portions 62 act on the corresponding clamping blocks 4 to push the clamping blocks to the right side away from the accommodating groove 3, so as to take out or place the product. In other embodiments, a first driving member (not shown in the figure) such as a pneumatic cylinder or a servo motor can be arranged at the pushing handle 61. The pushing handle 61 can be automatically driven to move to the right side, so that all the clamping blocks 4 are away from the accommodating groove 3 to take out or place the product, and automatic testing is realized.

[0034] The opening clamp assembly 8 comprises a moving rod 83 arranged on one side of the clamp block 4 and located in the height space, a mounting seat 81 arranged on the test plate 2, and an opening clamp block 82 rotatably arranged on the mounting seat 81 and driving the moving rod 83 to move horizontally so that the clamp block 4 is away from the containing groove 3. The opening clamp block 82 is rotatably arranged on the mounting seat 81 through a rotating shaft. The test plate 2 is provided with a first avoiding opening 21 for the opening clamp block 82 to move. The pusher 6 is provided with a second avoiding opening 63 for the opening clamp block 82 to move at a position corresponding to the first avoiding opening 21. In the embodiment, three clamp blocks 4 are arranged. The bottom of each clamp block 4 is provided with a moving rod 83 extending into the height space. The end of the moving rod 83 is a contact end for the opening clamp assembly 8 to act. Since the clamp block 4 and the opening clamp assembly 8 are both arranged in an arc shape, the middle moving rod 83 extends into the inside of the pusher 6, and the front and rear moving rods 83 are located outside the pusher 6. Therefore, the test plate 2 is provided with three first avoiding openings 21, and the pusher 6 is provided with only one second avoiding opening 63. In other embodiments, the number and position of the second avoiding openings 63 can be arranged according to the actual arrangement mode of the clamp block 4 and the opening clamp assembly 8, which is not limited herein. On the one hand, the left and right lengths of the second avoiding openings 63 limit the moving distance of the pusher 6 in the left and right directions. On the other hand, the opening clamp assembly 8 extends downward into the second avoiding opening 63 in the inside of the pusher 6, which can also limit the pusher 6 in the horizontal direction to prevent the pusher 6 from being separated from the left side.

[0035] Correspondingly, the bottom of the pusher 6 is provided with a first avoiding groove 64 for the moving rod 83 to move. The base 1 is provided with a second avoiding groove 11 for the pusher 6 to move, a third avoiding groove 12 for the moving rod 83 to move, and a fourth avoiding groove 13 for the clamp block 4 to move.

[0036] The upper end of the opening clamp block 82 is a pressing handle 821, and the lower end is an acting end 822 for driving the moving rod 83 to move. In the embodiment, the pressing handle 821 can be manually driven to rotate the opening clamp block 82 to drive the moving rod 83 to move. In other embodiments, a second driving member (not shown in the figure) such as a gas cylinder or a servo motor can be arranged at the pressing handle 821 to automatically drive the opening clamp block 82 to rotate. The driving end 822 of the opening clamp block 82 drives the moving rod 83 to move to the right to make the clamp block 4 away from the containing groove 3 to facilitate taking and placing products, and realizes automatic testing.

[0037] When the universal test fixture 100 is applied, if the product 200 has multiple conductive terminals 202 that need to be tested, the pushing piece 6 is pushed to the right, all the clamping blocks 4 are driven to move away from the accommodating groove 3, the conductive terminals 202 of the product 200 are placed into the accommodating groove 3, at this time the spring is compressed, the pushing piece 6 is released, the spring is stretched to push the clamping blocks 4 to one side of the accommodating groove 3, the clamping blocks 4 are directly abutted on the outer periphery of the conductive terminals 202 of the product, the limiting portion 42 can limit the movement of the conductive terminals 202 in the horizontal direction, so as to clamp the product 200, after the product is tested, the pushing piece 6 is pushed to the right, all the clamping blocks 4 are driven to move away from the accommodating groove 3, the product is taken out from the accommodating groove 3, a new product is placed to continue the next round of testing, if the product has only one conductive terminal that needs to be tested, any one of the accommodating grooves 3 can be selected, then the opening and clamping assembly 8 corresponding to the accommodating groove 3 is selected, the pressing handle 821 is driven to rotate the opening and clamping block 82, so as to drive the movement of the moving rod 83 to move the clamping blocks 4 away from the accommodating groove 3, the conductive terminal 202 of the product 200 is placed into the accommodating groove 3, at this time the spring is compressed, the pressing handle 821 is released, the spring is stretched to push the clamping blocks 4 to one side of the accommodating groove 3, the clamping blocks 4 are directly abutted on the outer periphery of the conductive terminals 202 of the product, the limiting portion 42 can limit the movement of the conductive terminals 202 in the horizontal direction, so as to clamp the product 200, after the product is tested, the pressing handle 821 is driven to rotate the opening and clamping block 82, so as to drive the movement of the moving rod 83 to move the clamping blocks 4 away from the accommodating groove 3, the product is taken out from the accommodating groove 3, a new product is placed to continue the next round of testing.
