Because the connector is soft and easy to bend and deform, the shape of the incoming material of the connector is usually extremely irregular, the connector must be regulated before testing so that the size of the connector is regulated to be within a specified range, and thus, when a product to be tested is transferred to the electrical testing equipment, the connector can be precisely pressed into an electrical testing cavity to conduct a test, but the conventional electrical testing equipment can rarely effectively fix the relative position between the connector of the product to be tested and a main body of the product, so that the connector is easy to deform again or relatively displace with the main body of the product to be tested, and once the connectors are relatively displaced, the connector cannot be precisely pressed into the electrical testing cavity to conduct a test, or cannot be effectively contacted with a blade pin in the electrical testing cavity, so that the crimping conduction between the connector and the electrical testing equipment can be influenced during the test, and the test result can be influenced.

The present embodiment is only used as an example and does not limit the technical scope of the present application. It can be appreciated that in other embodiments, the product alignment device of the present application is not limited to conducting test only on the connector of the electronic product, but also can be used for conducting test on the portion to be tested of any electronic product, which is not limited herein.

The following describes preferred embodiments of the electrical test platform structure and the conduction test apparatus provided in the present application with reference to fig. 1 to 5.

A conduction test apparatus (not shown) for conducting a conduction test of an electronic product before shipment from a factory includes a handling mechanism (not shown) as shown and an electrical test platform structure 100 as shown in fig. 1. The electrical testing platform structure 100 has an electrical testing cavity 101, the electrical testing cavity 101 is used for accommodating a portion to be tested of a product to be tested (in this embodiment, the portion to be tested is a connector of the product to be tested, and the portion to be tested is the connector) and the handling mechanism is used for transferring the product to be tested from the equipment of the previous process to the electrical testing platform structure 100, so that the connector can be inserted into the electrical testing cavity 101 for conducting testing.

In some embodiments, as shown in FIG. 1, an electrical measurement platform structure 100 includes a base 110, a support plate 120, and an electrical measurement mechanism 150. The supporting plate 120 is disposed parallel to the base 110, and is movably connected to the base 110, and is controllably movable in a height direction (indicated in the figure) relative to the base 110, and the supporting plate 120 is used for carrying a main body of a product to be tested. The electrical measuring cavity 101 is arranged in the electrical measuring mechanism 150, a conductive part (not shown in the figure) is arranged on the side wall of the electrical measuring cavity 101, and the dimension of the electrical measuring cavity 101 is changeable in a pressing direction perpendicular to the height direction, so that a connector of a product to be measured can be pressed and limited in the electrical measuring cavity 101 and contacted with the conductive part.

Specifically, the support plate 120 is connected to the base 110 through a plurality of guide posts, and the guide posts are disposed at the lower side of the support plate 120 along a height direction, and each guide post is disposed through the base 110. The base 110 is provided with a first driving member 140, the first driving member 140 may be a driving source such as an air cylinder or a hydraulic cylinder, and an output end of the first driving member 140 is connected to the supporting plate 120, and the first driving member 140 is used for driving the supporting plate 120 to move up and down relative to the base 110, so that the supporting plate 120 can adjust a height to adapt to a relative position between a main body of a product to be tested and a connector when the product to be tested is transferred to the electrical testing platform structure 100.

In this way, before the conveying mechanism releases the main body of the product to be tested and the connector, the supporting plate 120 moves upwards to receive the lower surface of the main body of the product to be tested, so that the relative position between the main body of the product to be tested and the connector can be maintained to the greatest extent in the interaction process of transferring the product to the electrical testing platform structure 100 from the conveying mechanism, so as to ensure that the connector can be accurately pressed into the electrical testing cavity 101.

Preferably, the support plate 120 is provided with a plurality of sucking discs 121 and/or a plurality of fixing columns 122, which are used for enabling the main body of the product to be tested to be more firmly fixed on the support plate 120, so that the relative position between the connector and the main body of the product to be tested can be better maintained.

In some embodiments, the electrical measurement mechanism 150 includes a fixed block 151, a pre-press block 152, and a final press block 154. The fixing block 151 is fixedly disposed at an edge position of the base 110, the pre-pressing block 152 is parallel to the fixing block 151 and is disposed at an interval, one side surface of the pre-pressing block 152 and one side surface of the fixing block 151 are disposed opposite to each other and together form the electrical measurement cavity 101, and the supporting plate 120 is lifted upwards to reach a maximum height lower than the top ends of the fixing block 151 and the pre-pressing block 152. The pre-pressing block 152 is movably coupled to the fixed block 151 through a sliding block 153, and the sliding block 153 is movably installed at an upper end of the fixed block 151, so that the pre-pressing block 152 can reciprocate on the fixed block 151 through the sliding block 153 along a pressing direction (i.e., a direction indicated by a symbol) coplanar with a conveying direction to change a size of the electrical measuring cavity 101 in the pressing direction.

In one embodiment, as shown in fig. 2, a second driving member 155 and a track guiding block 156 are fixedly arranged on the fixed block 151, the track guiding block 156 is arranged along the height direction (i.e. the direction indicated in the figure), the output end of the second driving member 155 is connected to the pre-pressing block 152, and the second driving member 155 is used for driving the pre-pressing block 152 to move up and down relative to the fixed block 151.

Preferably, as shown in fig. 3, one side of the track guiding block 156 has a guiding surface 1561, and the guiding surface 1561 includes a first guiding surface 1561a, a second guiding surface 1561b and a third guiding surface 1561c which are sequentially connected in the height direction, wherein the second guiding surface 1561b is a curved surface, and two ends of the second guiding surface 1561b are respectively connected with the first guiding surface 1561a and the third guiding surface 1561 c. In the pressing direction, the distance between the third guide surface 1561c and the plane of the pre-pressing block 152 on the side surface thereof near the fixed block 151 is greater than the distance between the first guide surface 1561a and the plane of the pre-pressing block 152 on the side surface thereof near the fixed block 151. Correspondingly, a sliding body 157 is disposed on the pre-pressing block 152, the sliding body 157 is preferably a roller capable of rotating around its central axis, the sliding body 157 is rollably connected to the guiding surface 1561, the pre-pressing block 152 is coupled to the track guiding block 156 through the sliding body 157, so that the pre-pressing block 152 can be driven by the second driving member 155 to move up and down along the height direction and simultaneously can also drive the sliding body 157 to move up and down along the height direction, thereby the sliding body 157 rolls on the guiding surface 1561, and the guiding surface 1561 can guide the pre-pressing block 152 to move along the pressing direction relative to the fixed block 151.

In this way, after the carrying mechanism presses the connector into the electrical measurement cavity 101, and the main body of the product to be measured is placed and fixed on the support plate 120, when the second driving member 155 drives the track guide block 156 to move upward, the second guide surface 1561b and the third guide surface 1561c can sequentially contact with the sliding body 157, so that the pre-pressing block 152 moves along the pressing direction towards the direction close to the fixing block 151, so that the connector is abutted in the electrical measurement cavity 101, and can be prevented from falling. Meanwhile, the supporting plate 120 is lifted upwards and the main body is fixed, at the moment, the carrying mechanism releases the connector, so that the product to be tested is not moved when being transferred to the electrical testing platform structure 100 from the carrying mechanism, and the supporting plate 120 and the pre-pressing block 152 of the electrical testing platform structure 100 move, thereby realizing seamless connection for transferring the product to be tested to the electrical testing platform structure 100, and still maintaining the relative position between the connector and the main body after being shaped after the product to be tested is transferred to the electrical testing platform structure 100. Then, when the second driving member 155 drives the trace guide block 156 downward, the second guide surface 1561b and the first guide surface 1561a can be brought into contact with the slider 157 in order to move the pre-press block 152 in the pressing direction away from the fixed block 151, so that the pre-press block 152 releases the connector, thereby enabling the connector to be removed from the electrical measuring cavity 101.

Thus, through the above design, the track guide block 156 is driven to move up and down by the second driving member 155 in a narrow space in the electrical measurement mechanism 150, and the pre-pressing block 152 can be driven to move in the horizontal pressing direction, so that the displacement in the height direction is converted into the displacement in the horizontal direction, and the occupied space of the electrical measurement mechanism 150 is saved.

In a preferred embodiment, referring to fig. 2, the slider 153 is connected to the fixed block 151 by an elastic member 158, and the elastic member 158 is configured to provide an elastic force that enables the pre-pressing block 152 to move in a direction approaching the fixed block 151 to press against the connector when the pre-pressing block 152 moves in a direction approaching the fixed block 151.

Thus, when the track guide block 156 drives the pre-pressing block 152 to move in the pressing direction in a direction away from the fixed block 151, the slider 153 also moves in a direction away from the fixed block 151, and at this time, the elastic member 158 is deformed in a recoverable manner. When the trajectory guide block 156 drives the pre-pressing block 152 to move in the pressing direction toward the fixed block 151, the deformation of the elastic member 158 is restored. The force of the pre-pressing block 152 acting on the connector is the elastic force generated by the elastic piece 158, so that the pre-pressing block 152 can pre-press the connector gently, and damage to the connector due to excessive pre-pressing force is avoided.

In an embodiment, as shown in fig. 1 and 4, the final pressing block 154 is a long strip structure movably disposed on the support plate 120 in the pressing direction, and a third driving member 159 is disposed at the bottom of the support plate 120, and the third driving member 159 may also be an air cylinder or a hydraulic cylinder, and the third driving member 159 is connected to the final pressing block 154 such that the final pressing block 154 can be driven by the third driving member 159 on the support plate 120 to move relative to the support plate 120 in the pressing direction.

The final pressing block 154 is used for moving the connector along the pressing direction towards the direction close to the fixed block 151 after the connector is pre-pressed and fixed by the pre-pressing block 152, so that one end of the final pressing block 154 is also propped against the connector, and the opposite sides of the connector are completely propped against the side wall of the electrical measurement cavity 101, so that the contacts on the connector can be completely contacted with the conductive parts arranged on the side wall of the electrical measurement cavity 101, and the conduction test of the connector can be smoothly started.

Preferably, the support plate 120 is provided with a linear guide rail assembly 160, the linear guide rail assembly 160 includes a guide block 161 and a guide rail 162, the guide block 161 is movably mounted on the guide rail 162 and can reciprocate along the guide rail 162, and the guide rail 162 is fixedly mounted on the underside of the final pressing block 154, so that the final pressing block 154 can also smoothly move relative to the support plate 120.

Further, as shown in fig. 5, because of the small size of the connector, in order to allow the pre-press block 152 and the final press block 154 to simultaneously contact the connector, the pre-press block 152 has a pre-press pin 1521 having an outer diameter slightly smaller than that of the connector, and the connector is held by the pre-press pin 1521 when the connector is pre-press-fixed. An avoidance groove 1541 is formed at the end of the final pressing block 154 near the electrical measurement cavity 101, and when the final pressing block 154 moves to a position near the electrical measurement cavity 101 and abuts against the connector, the part of the pre-pressing needle 1521 abutting against the connector is just accommodated in the avoidance groove 1541.

Therefore, under the condition that the size of the connector is very small, the pre-pressing block 152 and the final pressing block 154 can be directly abutted against the connector by adopting the design, compared with the mode that the final pressing block 154 is abutted against the pre-pressing block 152, the pre-pressing block 152 is used for transmitting the abutting force applied by the final pressing block 154 to the connector, the transmission of the abutting force is more stable, and the contact point of the connector can be fully contacted with the conductive part in the electrical measuring cavity 101, so that the testing effect is ensured.

It should be noted that, the electrical testing platform structure 100 may be provided with only the pre-pressing block 152, and the final pressing block 154 is not provided, and the pre-pressing block 152 only supports and fixes the connector in the electrical testing cavity 101, but obviously, the pre-pressing block 152 performs pre-pressing and fixing on the connector, and the final pressing block 154 completely presses the connector in the electrical testing cavity 101, so that the electrical testing cavity 101 can be completely contacted with the conductive part provided on the side wall of the electrical testing cavity 101, and thus better testing precision can be ensured.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only one embodiment of the utility model, which is described in more detail and is not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
