Description

Technical Field

[0001] This invention relates to the field of product testing technology, and more specifically to a product clamping and positioning device. Background Technology

[0002] In the production and testing of electronic products such as mobile phone component modules, some products have a unique double-layer structure, where the target surface to be tested is located on the lower layer and is obscured by the upper layer. Traditional clamping devices typically use a single vertical lifting method to move the pressure head to fix the product. When dealing with products with obstructed structures, the pressure head cannot move directly vertically downwards to the target surface for clamping. Forcing downward pressure would collide with the upper structure and damage the product. Therefore, existing clamping and positioning devices struggle to effectively clamp the target surface of the lower layer without damaging the product, causing the lower test probe to easily shift the product during upward testing, affecting the accuracy and stability of the test. Summary of the Invention

[0003] The purpose of this invention is to provide a product clamping and positioning device that, by configuring a specific clamping module on the upper fixture, enables the clamping module to achieve a composite motion path as the upper fixture moves: first, it moves downward synchronously for a first stroke; then, it moves horizontally for a second stroke until it is directly above the target surface of the product; and finally, it moves downward for a third stroke to clamp onto the target surface of the product. This solves the problem that traditional devices cannot bypass the upper layer of the product's obstruction. By extending horizontally, it avoids structural interference and achieves precise clamping and positioning of the obstructed target surface of the product. This, combined with the test probe at the bottom of the lower fixture, allows for stable testing and significantly improves the testing reliability of irregularly shaped products.

[0004] To achieve the above objectives, the present invention provides a product clamping and positioning device, comprising: A lower fixture is used to support the product, and a test probe that can be raised and lowered and is used to contact the target surface of the product is provided at the bottom of the lower fixture; An upper fixture is positioned above the lower fixture and can move downward in a controlled manner. A pressing module is provided on the upper fixture. The pressing module is configured to move downward synchronously with the upper fixture for a first stroke, then move horizontally for a second stroke to directly above the target surface of the product, and then move downward for a third stroke to press against the target surface of the product.

[0005] Optionally, the upper fixture includes: A first fixture is disposed above the lower fixture. The first fixture is provided with a plurality of positioning pins, which correspond to and cooperate with the positioning grooves of the lower fixture. Limit blocks are provided on the positioning pins. A second fixture is mounted on the first fixture and can be moved up and down in a controlled manner above the first fixture. A first spring is provided between the second fixture and the first fixture.

[0006] Optionally, the clamping module includes: The fixing frame is fixedly mounted on the first fixture; A U-shaped block is mounted on the fixed frame and can reciprocate horizontally. A first idler wheel is provided on the side of the U-shaped block. A lifting block is disposed between the bottom and top of the U-shaped block and can move vertically up and down. A second spring is disposed between the bottom of the lifting block and the bottom of the U-shaped block. A first fixing block is disposed at the bottom of the first fixture, and a third spring is disposed between the bottom of the first fixing block and the side of the U-shaped block; A pressing part is provided on the lifting block, and the pressing part descends synchronously with the first fixture for a first stroke; A first cam block is disposed at the bottom of the second fixture. A cam groove is provided on the side of the first cam block facing the first idler wheel. The cam groove includes a horizontal moving part and a vertical moving part from bottom to top. The horizontal moving part, the first idler wheel and the third spring cooperate to drive the pressing part to move a second stroke. The pressure head is located at the bottom of the second fixture and directly above the clamping part. The pressure head, the second spring, the vertical moving part cooperate with the first idler wheel to drive the clamping part to move a third stroke.

[0007] Optionally, the lower fixture is provided with a gold-plated copper block and an adapter pin connected to the gold-plated copper block. The gold-plated copper block and the adapter pin cooperate with the wiring piece on the edge of the product to control the circuit connection.

[0008] Optionally, the first fixture is provided with a wiring module, the wiring module comprising: A connecting block is located at the bottom of the first fixture and can move back and forth horizontally; The second idler wheel is mounted on the connecting block; A connector hook is provided on the side of the connecting block facing the product, and is used to hook the connector piece into contact with the gold-plated copper block. A second fixing block is disposed at the bottom of the first fixture, and a fourth spring is disposed between the second fixing block and the other side of the connecting block; A wedge block is disposed at the bottom of the second fixture. The wedge block, the second idler wheel, and the fourth spring cooperate to drive the wiring hook to move away from the product.

[0009] Optionally, the lower fixture is further provided with a positioning block that can move in the horizontal direction and a positioning plate that can rotate in the horizontal axis.

[0010] Optionally, the lower fixture is embedded with a liftable platform, which is used to support the test probe.

[0011] Optionally, a wiring terminal is provided at the bottom of the lifting platform.

[0012] The beneficial effects of this invention are as follows: by configuring a specific clamping module on the upper fixture, the clamping module can achieve a composite motion path as the upper fixture moves, first moving downward in a first stroke, then moving horizontally in a second stroke to directly above the target surface of the product, and finally moving downward in a third stroke to clamp onto the target surface of the product. This solves the problem that traditional devices cannot bypass the upper layer of the product's obstruction. By extending horizontally, structural interference is avoided, and precise clamping and positioning of the obstructed target surface of the product is achieved. This, combined with the test probe at the bottom of the lower fixture, enables stable testing and significantly improves the testing reliability of irregularly shaped products. Complex spatial obstacle avoidance maneuvers can be achieved simply by providing vertical power to the second fixture through an external drive structure. The first fixture descends first to complete the initial mold closing and positioning, supported by the first spring. Then, the second fixture drives the first cam block to continue descending. The horizontal movement of the cam groove, in conjunction with the first idler wheel and the third spring, converts the vertical pressure into the horizontal displacement of the clamping part to bypass the obstacle. When the clamping part reaches directly above the target surface, the second fixture descends, causing the pressure head to directly abut against and push the clamping part downward. With the buffering and resetting effect of the second spring, the final vertical clamping action is completed. By decomposing a single power source and converting it into three orderly strokes, the equipment structure is greatly simplified. There is no need to configure additional horizontal drive cylinders and complex timing controllers, which significantly reduces manufacturing costs and failure rates, and ensures the tight synchronization of mechanical movements.

Detailed Implementation

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0018] Please see Figures 1 to 6 The product 3 clamping and positioning device shown in a preferred embodiment of this application includes a lower fixture 1 and an upper fixture 2. The lower fixture 1 is used to support the product 3, and a test probe 4 that can be raised and lowered and is used to contact the target surface of the product 3 is provided at the bottom of the lower fixture 1. The upper fixture 2 is located above the lower fixture 1 and can be moved downward in a controlled manner. A clamping module 5 is provided on the upper fixture 2. The clamping module 5 is configured to move downward synchronously with the upper fixture 2 for a first stroke, then move horizontally for a second stroke until it is directly above the target surface of the product 3, and then move downward for a third stroke to clamp onto the target surface of the product 3.

[0019] According to the embodiment of the present invention, by configuring a specific pressing module 5 on the upper fixture 2, the pressing module 5 can achieve a composite motion path as the upper fixture 2 moves, first moving downward synchronously for a first stroke, then moving horizontally for a second stroke to directly above the target surface of the product 3, and finally moving downward for a third stroke to press against the target surface of the product 3. This solves the problem that traditional devices cannot bypass the upper obstruction of the product 3. By extending horizontally, structural interference is avoided, and precise pressing and positioning of the obstructed target surface of the product 3 is achieved. This, in conjunction with the test probe 4 at the bottom of the lower fixture 1, allows for stable testing and significantly improves the testing reliability of the irregularly shaped product 3.

[0020] The following detailed description uses specific examples: Specifically, please see Figure 1 and Figure 2The upper fixture 2 includes a first fixture 21 and a second fixture 22. The first fixture 21 is disposed above the lower fixture 1 and is provided with a plurality of positioning pins 211, which correspond to and cooperate with the positioning grooves of the lower fixture 1. The positioning pins 211 are provided with limit blocks 212. The second fixture 22 is disposed on the first fixture 21 and can move up and down in a controlled manner above the first fixture 21. A first spring 221 and a positioning post 222 are provided between the second fixture 22 and the first fixture 21, and the second fixture 22 can move up and down along the positioning post 222. Initially, the second fixture 22 is driven by an external drive mechanism to move the first fixture 21 downwards in sync (at this time, the first spring 221 is in normal condition). When the positioning pin 211 enters the positioning groove of the lower fixture 1 and the limiting block 212 touches the lower fixture 1, the first fixture 21 stops descending, thereby completing the first stroke and achieving mold closing with the lower fixture 1. At this time, the compression of the first spring 221 allows the second fixture 22 to continue descending, providing stroke space and power source for the subsequent pressing module 5 to convert to horizontal movement and final pressing movement.

[0021] Please see Figure 2 and Figure 3 The clamping module 5 includes a fixed frame 51, a U-shaped block 52, a lifting block 53, a first fixed block 54, a clamping part 55, a first cam block 56, and a pressure head 57. The fixed frame 51 is fixedly mounted on the first fixture 21. The U-shaped block 52 is mounted on the fixed frame 51 and can reciprocate horizontally. A first idler wheel 58 is provided on the side of the U-shaped block 52. The lifting block 53 is located between the bottom and top of the U-shaped block 52 and can move vertically. A second spring 531 is provided between the bottom of the lifting block 53 and the bottom of the U-shaped block 52. The first fixed block 54 is located at the bottom of the first fixture 21. A third spring 541 is provided between the first fixed block 54 and the side of the U-shaped block 52. The clamping part 55 is mounted on the lifting block 53 and descends synchronously with the first fixture 21 for a first stroke. The first cam block 56 is located at the bottom of the second fixture 22. A cam groove 561 is formed on the side of the first cam block 56 facing the first idler wheel 58. The cam groove 561 includes a horizontal moving part 562 and a vertical moving part 563 from bottom to top. The horizontal moving part 562, the first idler wheel 58, and the third spring 541 cooperate to drive the pressing part 55 to move a second stroke. The pressure head 57 is located at the bottom of the second fixture 22 and directly above the pressing part 55. The pressure head 57, the second spring 531, the vertical moving part 563, and the first idler wheel 58 cooperate to drive the pressing part 55 to move a third stroke.

[0022] After the first fixture 21 is held still by the limiting block 212 and the mold is closed, the external drive mechanism continues to drive the second fixture 22 to move downward. At this time, the first spring 221 is compressed, and a relative displacement occurs between the first fixture 21 and the second fixture 22. As the second fixture 22 moves downward, the first cam block 56 fixed at the bottom of the second fixture 22 descends synchronously. The cam groove 561 on the first cam block 56 forces the first idler wheel 58 to move in the horizontal direction. Under the combined action of the first idler wheel 58 and the third spring 541, the U-shaped block 52 drives the lifting block 53 and the pressing part 55 to extend into the inside of the product 3 in the horizontal direction (it should be noted that a sliding rail is provided between the U-shaped block 52 and the fixed frame 51) until the end of the pressing part 55 passes around the upper shielding part of the product 3 and reaches directly above the target surface of the product 3. At this time, the second stroke ends. When the first idler wheel 58 moves to the junction of the vertical moving part 563 and the horizontal moving part 562 of the cam groove 561, the horizontal displacement stops, and the external drive mechanism continues to drive the second fixture 22 downward. At this time, the pressure head 57 set at the bottom of the second fixture 22 moves directly downward and abuts against the pressing part 55. The pressure head 57 drives the lifting block 53 to move downward and vertically within the U-shaped block 52 by overcoming the elastic force of the second spring 531 (it should be noted that a sliding rail is provided between the lifting block 53 and the U-shaped block 52), so that the pressing part 55 presses down vertically and finally presses tightly against the target surface of the product 3, thus completing the three-stage compound pressing action driven by a single power.

[0023] Further, please see Figure 5 and Figure 6 The lower fixture 1 is equipped with a gold-plated copper block 11 and an adapter pin connected to the gold-plated copper block 11. The gold-plated copper block 11, the adapter pin, and the wiring piece 32 on the edge of the product 3 cooperate to control the circuit continuity. Through the excellent conductivity of the gold-plated copper block 11 and the flexible contact of the adapter pin, it can be ensured that while the product 3 is being pressed and positioned, its functional circuit can be stably connected to the external testing system, providing the necessary hardware interface environment for subsequent extraction of electrical performance parameters.

[0024] Further, please see Figure 2 and Figure 4The first fixture 21 is equipped with a wiring module 6. The wiring module 6 includes a connecting block 61, a second idler wheel 62, a wiring hook 63, a second fixing block 64, and a wedge block 65. The connecting block 61 is located at the bottom of the first fixture 21 and can reciprocate horizontally. The second idler wheel 62 is located on the connecting block 61. The wiring hook 63 is located on the side of the connecting block 61 facing the product 3 and is used to hook the wiring piece 32 into contact with the gold-plated copper block. The second fixing block 64 is located at the bottom of the first fixture 21, and a fourth spring 66 is located between the second fixing block 64 and the other side of the connecting block 61. The wedge block 65 is located at the bottom of the second fixture 22, and the wedge block 65, the second idler wheel 62, and the fourth spring 66 cooperate to drive the wiring hook 63 to move away from the product 3. During the synchronization process of the second stroke, the wedge block 65 set at the bottom of the second fixture 22 moves down and presses the second idler wheel 62 on the wiring module 6 (at this time, the second idler wheel 62 cannot move down because the first fixture 21 is closed). With the cooperation of the fourth spring 66, the second idler wheel 62 drives the connecting block 61 and the wiring hook 63 to move away from the product 3 (it should be noted that a sliding rail is provided between the connecting block 61 and the first fixture 21) so that the wiring piece 32 of the product 3 can achieve a stable contact connection with the gold-plated copper block 11 on the lower fixture 1, and the electrical performance test circuit is pre-connected.

[0025] Please see Figure 5 and Figure 6 The lower fixture 1 is also equipped with a positioning block 12 that can move horizontally and a positioning plate 13 that can rotate along the horizontal axis. When the product 3 is placed on the lower fixture 1, the position of the product 3 is pre-adjusted and coarsely positioned by the physical constraints of the positioning block 12 and the positioning plate 13, preventing the product 3 from shifting significantly before the clamping module 5 is activated, thereby ensuring that the clamping part 55 can accurately align with the target surface of the product 3. The positioning block 12 can be manually moved to adjust its position, while the positioning plate 13 can be rotated by a cylinder.

[0026] Please see Figure 1 The lower fixture 1 is embedded with a liftable platform 7, which carries the test probe 4. A connector 8 is located at the bottom of the platform 7. After the product 3 is fully clamped and positioned by the clamping part 55, the liftable platform 7 embedded in the lower fixture 1 rises in a controlled manner, causing the test probe 4 carried on it to pass upwards through the lower fixture 1. The test probe 4 pushes upwards from below and makes stable electrical contact with the target surface of the product 3. Finally, through a complete test circuit consisting of the connector 8, adapter pin, gold-plated copper block 11, and test probe 4, various electrical performance indicators of the product 3 are tested.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
