[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: See Figures 1 to 5 As shown, a rapid positioning mechanism for testing a horizontal actuator of an automobile seat comprises a frame 1, a positioning block 2 provided on the frame, a pressing mechanism, an energizing mechanism, a pushing mechanism, and a controller 3, wherein the controller is electrically connected to the pressing mechanism and the pushing mechanism;

[0032] A product placement slot 4 is provided on the top rear side of the positioning block, and the power supply mechanism is two sets of power plugs 5, which are respectively arranged at the front end of the product placement slot, and the power plugs are arranged rearward;

[0033] The top of the pressing mechanism is provided with a pressing plate 6, which is rotatably arranged above the product placement slot or rotatably arranged above the front end of the positioning block;

[0034] The pushing mechanism includes a splint 7, a discharge rod 8 and a driving mechanism for driving the splint and the discharge rod to move forward and backward. The splint is arranged at the rear end of the product placement slot, and the discharge rod is arranged above the positioning block at the front end of the product placement slot. The driving mechanism drives the splint and the discharge rod to move closer to or away from the product placement slot.

[0035] In this embodiment, during actual use, the operator places the product into the product placement slot. There are two interfaces on the product 9, and each interface is arranged opposite to a set of energized plugs. Then, the operator first connects the screw (flexible screw) on the product to the detection mechanism in the detection device. The height of the unloading rod is above the positioning block, but below the top surface of the product, and it is directly opposite to the front end of the product. After the product is placed in the product positioning slot, the product is located between the clamping plate and the front end face of the product positioning slot. The operator presses the following controller, and the controller first controls the pressing mechanism to work, driving the pressing plate to rotate above the product. Then, the pressing plate presses the product, and the driving mechanism drives the clamping plate and the unloading rod to move forward. After the clamping plate contacts the rear end of the product, it pushes the product forward, so that the energized plug directly inserts into the interface to supply power to the product. In this way, the product works, and the detection mechanism detects the displacement of the screw to detect whether the product is qualified (or when the pressing mechanism and the driving mechanism are controlled to work first, the operator connects the screw to the detection mechanism, which can further shorten the detection efficiency). After the detection is completed, the operator separates the screw from the detection mechanism. At the same time, the driving mechanism drives the clamping plate and the unloading rod to move backward. The clamping plate contacts the clamping force on the product. At the same time, after the unloading rod moves to a certain position, it contacts the product and pushes the product backward, so that the interface of the product is separated from the energized plug. Then, the positioning plate is separated from the product, and the operator can take away and replace the product. In this embodiment, the operator only needs to place and remove the product and connect the screw to the driving device at the same time, without having to supply power to the product to achieve automatic power-on work, which can reduce the labor intensity of the operator, prevent the occurrence of electric shock, and reduce potential safety hazards.

[0036] See Figures 1 to 5 As shown, the driving mechanism includes a longitudinal cylinder 10 and a sliding plate 11. A chute 12 is provided in the middle of the positioning block. The two ends of the chute are respectively connected to the front side and the rear end face of the positioning block. The middle of the sliding plate is movably arranged in the chute. The rear end of the sliding plate is arranged at the rear side of the positioning block, and the front end of the sliding plate is arranged at the front side of the positioning block;

[0037] The longitudinal cylinder is installed at the front end of the positioning block, and the output shaft of the longitudinal cylinder is connected to the front end of the sliding plate;

[0038] The bottom of the clamping plate is vertically installed at the rear side of the top of the sliding plate. A convex block 13 is respectively provided on both sides of the top of the front end of the sliding plate. A screw hole is provided in the convex block. The middle of each unloading rod is screwed onto the convex block, and the rear end of the unloading rod is arranged above the positioning block. Among them, a rubber head 14 is provided at the rear end of the unloading rod, so that the unloading rod contacts the product through the rubber head to prevent damage to the product caused by rigid impact.

[0039] In this embodiment, a longitudinal cylinder is used to drive the sliding plate to move back and forth. Through the forward and backward movement of the sliding plate, the clamping plate and the unloading rod are simultaneously driven to move back and forth. The distance between the clamping plate and the unloading rod is larger than the width of the product. Therefore, when the product is placed, it will not touch the clamping plate and the unloading rod. The setting of the convex block and the screw hole can adjust the distance of the unloading rod. Further, a cylinder can also be arranged on the convex block. The unloading rod is movably connected to the convex block, and the cylinder is used to drive the unloading rod to move back and forth. The product is pushed away from the power plug through the forward and backward movement of the unloading rod. In this structure, more cylinders need to be arranged, and the cost will be relatively higher, but the unloading efficiency will be higher.

[0040] See Figures 1 to 5 As shown, there are two groups of the clamping plates, and the two groups of the clamping plates are installed on both sides of the top of the sliding plate at left and right intervals; a protective layer 15 is provided on the front end face of each group of the clamping plates. Through the setting of the protective layer, when the clamping plate moves forward to push the product forward, the protective layer plays a buffering and protecting role to prevent the product from being damaged by the clamping plate.

[0041] See Figures 1 to 5 As shown, the pressing mechanism includes a rotary telescopic cylinder 16 and a pressing plate 6. The rotary telescopic cylinder is installed on the frame in front of the positioning block, and the front end of the pressing plate is connected to the output shaft at the top of the rotary telescopic cylinder; the rotary telescopic cylinder drives the rear end of the pressing plate to rotate and be arranged above the product placement groove or above the front end of the positioning block.

[0042] A pressing member 18 is installed at the rear end of the pressing plate. The bottom of the pressing member is arranged below the pressing plate, and the top of the pressing member is arranged above the pressing plate.

[0043] The rotary telescopic cylinder is adopted to drive the pressing member to rotate above the product placement groove or outside the front end of the positioning block. When pressing is required, it drives the pressing member to rotate above the product placement groove and then press down, driving the pressing member to press the product so that the bottom surface of the product abuts against the bottom surface of the product placement groove, ensuring the stable position of the product during movement and enabling the interface height position to be directly opposite to the power connection head.

[0044] See Figures 3 to 5 As shown, the pressing member includes a connecting rod 19, a connecting block 20, a spring 21 and two groups of supporting wheels 22. A vertical through hole is provided at the rear end of the pressing plate. The middle part of the connecting rod is movably inserted into the vertical through hole. The top of the connecting block is connected to the bottom of the connecting rod. A limit nut 23 is screwed on the outer part of the connecting rod above the pressing plate. The spring is sleeved on the outer part of the connecting rod. The bottom of the spring abuts against the top surface of the connecting block, and the top of the spring abuts against the bottom surface of the pressing plate. The spring pushes the connecting block and the connecting rod to move downward so that the bottom surface of the limit nut abuts against the top surface of the pressing plate;

[0045] Two sets of notches are provided at intervals on the bottom of the connecting block. The middle of each set of supporting wheels is rotatably installed in one set of notches, and the bottom outer surface of the supporting wheel is located below the bottom surface of the connecting block.

[0046] When the pressure plate is arranged directly above the product placement groove, the axis of the supporting wheel is arranged perpendicular to the moving direction of the clamping plate.

[0047] In this embodiment, a supporting roller is adopted. After the rotary telescopic cylinder drives the pressing member to move above the product and then drives the pressing member to abut against the top surface of the product, the bottom surface of the supporting wheel will first abut against the top surface of the product, and then the pressure plate continues to move downward to compress the spring. When compressed to a certain extent, the pressure plate stops moving downward. The elastic force of the spring is used to apply a downward pressure to the connecting block and the supporting wheel, and the product is pressed by the elastic force of the spring. Then when the clamping plate pushes the product to move forward, since the supporting wheel is rotatably connected to the connecting block, the position of the supporting wheel will not change. Therefore, when the product moves, the supporting wheel rolls, playing a role of rolling pressing, which neither affects the normal movement of the product nor scratches the product.

[0048] Further, a protective layer is provided on the bottom surface of the product positioning groove. Through the setting of the protective layer, the protective layer is made of a material with a certain flexibility (the hardness of this material is lower than that of the product), such as plastic or a slightly harder rubber. When the supporting wheel presses the product and the clamping plate pushes the product to move forward, the protective layer plays a role in protecting the bottom surface of the product and preventing the product from being scratched. If the protective layer is damaged after long-term use, the protective layer can be replaced regularly.

[0049] See Figures 1 to 5 As shown, a limiting baffle 17 is respectively provided on the left and right sides of the front end of the product positioning groove. In this way, when the product is placed in the product positioning groove, the product will be located between the two sets of limiting baffles, playing a role of quickly placing and positioning the product, so that when the product moves forward, the interface on it will be directly opposite to the power plug, ensuring the accuracy of the plug-in fit between the power plug and the product interface.
