Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically to an electrical connector clamping mechanism and a CCD detection device. Background Technology

[0002] CCD inspection uses an industrial camera to take high-precision, multi-angle photos of a product, capturing images of various parts of the product to detect defects invisible to the naked eye. Current CCD inspection devices typically include a feeding mechanism, a clamping mechanism, and a CCD inspection mechanism. Products requiring CCD inspection are generally those with high precision requirements, such as films and electronic components. The clamping mechanism's role is to secure the product and ensure its stability during inspection.

[0003] Electrical connectors are typically circular or rectangular. For example... Figure 1 As shown, the board-to-board connector is a rectangular connector, comprising a rectangular housing 11 and multiple sets of L-shaped spring contacts 12 installed within the housing 11. In actual use, the multiple sets of L-shaped spring contacts 12 are spaced apart along the length of the housing 11 between its two ends. There are 20 to 30 sets of spring contacts 12. Since a CCD detection device is needed to detect the spring height of each spring contact 12, a clamping mechanism is required to fix it in place to ensure inspection accuracy and prevent the connector from shaking during CCD detection. Precise positioning of the connector must also be ensured when switching to the next connector.

[0004] Meanwhile, existing technologies suffer from long changeover times when switching to other models of electrical connectors, and the product holder (product placement seat) position needs to be corrected after the changeover, making the changeover very troublesome and resulting in low testing efficiency. Summary of the Invention

The depths of the housing placement slot and the spring contact receiving slot are respectively greater than the height from the upper end of the housing to the lower end of the spring contact. The left and right sidewalls of the housing placement slot are symmetrically provided with limiting structures for supporting the lower end of the housing.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] Example 1

[0041] like Figure 1 — Figure 9As shown, an electrical connector clamping mechanism is provided. The electrical connector 1 is a rectangular electrical connector with a rectangular housing 11 and multiple sets of springs 12. The electrical connector clamping mechanism includes a product placement seat 2 and a telescopic clamping device 3. The product placement seat 2 includes a housing placement groove 21 and a spring receiving groove 22 that are interconnected.

[0042] The housing placement groove 21 is used to place the housing 11, and the inner sidewall of the housing placement groove 21 is clearance-fitted with the outer sidewall of the housing 11; telescopic tightening devices 3 are symmetrically arranged on the rear sidewall of the housing placement groove 21, and at least one telescopic tightening device 3 is arranged on its left or right sidewall; the spring receiving groove 22 is located at the front end of the product placement seat 2; the depths of the housing placement groove 21 and the spring receiving groove 22 are respectively greater than the height from the upper end of the housing 11 to the lower end of the spring 12, and the lower side of the spring 12 is spaced apart from the upper side of the spring receiving groove 22; the left and right sidewalls of the housing placement groove 21 are symmetrically provided with limiting structures 24 for supporting the lower end of the housing 12. By setting up a telescopic clamping device 3, the housing 11, placed in the housing placement slot 21, is pressed from the rear to the front, so that the rear side of the housing 11 abuts against the telescopic clamping device 3, and the front side of the housing 11 abuts against the front wall of the housing placement slot 21, thereby completing the lateral positioning fixation of the housing 11. At the same time, the limiting structure 24 can effectively support and quickly position the lower side of the housing. By adopting this technical measure, it can be ensured that the electrical connector is fixed on the product placement seat 2 without shaking, thereby ensuring the detection accuracy; when switching to the next electrical connector, it can also ensure that the electrical connector can be accurately positioned, thereby effectively improving the detection efficiency.

[0043] like Figure 2 — Figure 5 As shown, the product placement base 2 has a square outer contour, and a T-shaped placement groove is formed at the upper end of the product placement base 2. The placement groove includes a housing placement groove 21 and a spring receiving groove 22. Specifically, as shown... Figure 3 , Figure 4 As shown, the side of the spring receiving groove 22 is designated as the front side, and the side away from the spring receiving groove 22 is designated as the rear side. Since the left and right length of the housing 11 is greater than the overall length of the spring 12, the length of the housing placement groove 21 is greater than the length of the spring receiving groove 22. The housing placement groove 21 is located in the middle of the product placement base 2; the spring receiving groove 22 is located at the front end of the product placement base 2 and communicates with the housing placement groove 21. The length and width of the spring receiving groove 22 are greater than the length and width of the spring 12. The housing placement groove 21 is used to place the housing 11, and the inner wall of the housing placement groove 21 is clearance-fitted with the outer wall of the housing 11; this structure is suitable for various models of electrical connectors with different housing sizes.

[0044] like Figure 3 — Figure 8As shown, telescopic clamping devices 3 are symmetrically arranged on the rear side wall of the housing placement groove 21, and at least one telescopic clamping device 3 is arranged on its left or right side wall. In a specific implementation, the inner side wall of the housing placement groove 21 away from the spring receiving groove 22 is the rear side wall. Two telescopic clamping devices 3 are symmetrically arranged on the rear side wall of the housing placement groove 21, and these two telescopic clamping devices 3 correspond to the rear sides of the left and right ends of the housing 11, respectively; one telescopic clamping device 3 is arranged on the right side wall of the housing placement groove 21, and this telescopic clamping device 3 corresponds to the right end of the housing 11.

[0045] like Figure 3 — Figure 8 As shown, the housing placement groove 21 and the telescopic tightening device 3 are detachably connected. The rear and right side walls of the housing placement groove 21 are provided with mounting holes for installing the telescopic tightening device 3. In actual use, the mounting holes include a rear side wall mounting hole 211 and a right side wall mounting hole 212. The telescopic tightening device 3 is a ball-head plunger. The end of the ball-head plunger furthest from the ball head is the connecting end. The ball head of the ball-head plunger faces into the housing placement groove 21, and the connecting end is threadedly connected to the mounting hole 211. After the ball-head plunger is installed, a portion of the ball head is positioned within the housing placement groove 21. When the housing 11 is inserted from above the housing placement groove 21, the side wall of the housing 11 presses the ball head, causing it to move towards the connecting end. Simultaneously, the ball head of the ball-head plunger applies a tightening pressure to one end of the housing 11 under the elastic force of an internal spring.

[0046] like Figure 3 — Figure 5 As shown, the front end of the housing placement groove 21 has a notch 221 that is lower than the rear end of the housing placement groove 21. In actual use, the notch 221 is located at both ends of the spring receiving groove 22. By setting the notch 221, the height of the left and right ends of the spring receiving groove 22 is reduced. When placing the electrical connector, the back of the housing 11 first rests against it and then moves downwards. The notch 221 forms a reference, preventing the spring from hitting the connector when it is first placed. After setting the notch 221, the rear side wall mounting hole 211 is set on the housing placement groove 21 below the upper side of the notch 221.

[0047] like Figure 3 — Figure 8As shown, the depths of the housing placement groove 21 and the spring receiving groove 22 are greater than the height from the upper end of the housing 11 to the lower end of the spring 12. Symmetrical limiting structures 24 for supporting the lower end of the housing 12 are provided on the left and right side walls of the housing placement groove 21. The lower side of the spring 12 is spaced apart from the upper side of the spring receiving groove 22. In actual use, since the heights of the housings 11 of different electrical connectors are also different, when the spring 12 is placed in the spring receiving groove 22, to prevent the lower side of the spring 12 from abutting against the upper side of the spring receiving groove 22 due to excessive downward movement, resulting in compression deformation, a spaced-apart arrangement is required between the lower side of the spring 12 and the upper side of the spring receiving groove 22. Therefore, the depths of the housing placement groove 21 and the spring receiving groove 22 are greater than the height from the upper end of the housing 11 to the lower end of the spring 12. Furthermore, by symmetrically providing limiting structures 24 on the left and right side walls of the housing placement groove 21 to support the lower end of the housing 12, excessive downward movement of the housing 11 and spring 12 due to excessive force when the housing 11 is inserted into the housing placement groove 21 is prevented. Simultaneously, since the limiting structures 24 provide support to the lower side of the housing 11, the housing 11 can be stably fixed in the housing placement groove 21, thus providing rapid positioning and stable support for the housing 11.

[0048] The upper and lower ends of the housing placement groove 21 are through structures. By adopting this technical measure, the housing placement groove 21 produced has high precision, and at the same time, it can reduce the overall weight of the product placement base 2.

[0049] like Figure 3 — Figure 8 As shown, the limiting structure 24 includes a limiting post 241; the front / rear side of the product placement seat 2, corresponding to the lower end of the housing 12, is provided with a limiting post mounting groove 25 that communicates with the housing placement groove 21; the limiting post 241 and the limiting post mounting groove 25 are clearance-fitted. In specific implementations, for ease of installation and replacement, the opening of the limiting post mounting groove 25 is located on the front side of the product placement seat 2. The limiting post mounting groove 25 is generally a square groove, with one end located inside the housing placement groove 21 and the other end located outside the product placement seat 2; correspondingly, the limiting post 241 is a square limiting post with a length matching the limiting post mounting groove 25. The clearance fit between the limiting post 241 and the limiting post mounting groove 25 enables a detachable connection. In actual use, the limiting structure 24 can be a fixed structure; the use of a detachable limiting post 241 allows for fine-tuning according to actual needs, such as reducing the height of the limiting structure 24 to accommodate electrical connectors with relatively high housing 11 heights. This technical measure effectively improves the applicability.

[0050] like Figure 3 — Figure 5As shown, the rear end of the product placement base 2 is provided with a retaining groove 23 that communicates with the housing placement slot 21. In actual use, since the housing 11 is spaced within the housing placement slot 21, it is inconvenient to remove the housing 11 from the housing placement slot 21. The retaining groove 23 exposes the middle of the rear side of the housing 11, preventing it from being blocked by the rear side of the housing placement slot 21 when removing the housing 11. The left and right lengths of the retaining groove 23 are less than the left and right lengths of the spring receiving slot 22, which are less than the left and right lengths of the housing placement slot 21. This technical measure facilitates installation and removal and effectively improves the efficiency of switching electrical connectors.

[0051] like Figure 2 As shown, the electrical connector clamping mechanism also includes a base plate 4; the upper end of the base plate 4 is detachably connected to a product placement seat 2. In specific implementation, two first magnets 27 are symmetrically arranged at the left and right ends of the bottom side of the product placement seat 2, and correspondingly, two second magnets 42 that cooperate with the first magnets 27 are provided on the base plate 4. In actual use, the length of the base plate 4 is greater than the length of two product placement seats 2, and two product placement seats 2 can be arranged on its upper side. When switching to other models of electrical connectors, there may be a problem of replacing the product placement seats 2. The connection structure and position between different product placement seats 2 and the base plate 4 remain unchanged, and the housing placement groove 21 and spring receiving groove 22 at its upper end are adjusted according to the size of the electrical connector. The product placement seat 2 and the base plate 4 are connected by magnets. Compared with detachable structures such as threaded connections, the magnetic connection has higher disassembly and assembly efficiency, effectively improving the efficiency of replacing product placement seats, thereby effectively improving the testing efficiency.

[0052] The product placement base 2 has positioning holes 26 at both ends of its bottom side; correspondingly, the base plate 4 has positioning pins 41 for engaging with the positioning holes 26. Rapid positioning can be achieved through the positioning holes 26 on the bottom side of the product placement base 2 and the positioning pins 41 on the base plate 4. By adopting the above technical measures, it is further ensured that when changing to different product placement bases 2, rapid positioning can be achieved, avoiding the need to correct the position of the product placement base, thereby improving testing efficiency.

In specific implementation, the base plate 4 is provided with a plurality of connection holes for connecting to the linear motor 51 at intervals along its front and rear length direction; the base plate 4 and the linear motor 51 are connected by screws, etc. The CCD camera lens and the light source 7 are located between the electrical control cabinet 6 and the linear motor 51 through the column 53, and the CCD camera lens and the light source 7 correspond to the upper end of the linear motor 51. When the spring 12 of the electrical connector is tested, the electrical connector clamping mechanism mounted on its upper end is first moved laterally by the linear motor 51 to the CCD camera lens and light source 7; if the position is offset back and forth, the linear guide rail 52 drives the linear motor 51 to adjust the back and forth position.
