The molded metal guide channel structure includes a horizontally arranged support substrate. The support substrate extends vertically upward on both sides in the width direction to form limiting side plates.

[0020] The height difference design between the limiting stage and the guide slide of the turntable structure prevents the glass slide from detaching from the turntable during the horizontal-vertical docking process.

[0021] A glass slide support plate is installed at the first end in the transverse conveying direction to ensure that the transfer device can smoothly connect with the glass slide on the incoming side; at the same time, the first actuating component adopts a design that combines a actuating notch and a glass pushing channel, so that the first actuating component can avoid the glass slide support plate and at the same time abut against both ends of the glass slide, avoiding the deflection caused by the glass slide being subjected to force on one side.

[0022] The real-time monitoring of the slide position is achieved through the linkage of the detection unit and the signal trigger, ensuring transfer accuracy and improving the stability of the entire device.

[0030] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0031] As shown in Figures 1 and 2, the automatic slide transfer device of this utility model includes a transverse conveying system and a longitudinal conveying system. The transverse conveying system includes a first slide guide groove 1 and a first actuating component 2. The first slide guide groove 1 extends transversely and is used to guide the slide to slide in the transverse direction. The first actuating component 2 is used to drive the slide to move along the first slide guide groove 1. The longitudinal conveying system includes a second slide guide groove 6 that is connected to the first slide guide groove 1 and a second actuating component 7 that drives the slide to move along the second slide guide groove 6.

[0032] Specifically, the first slide guide channel 1 is integrally formed by bending a metal guide channel structure. This formed metal guide channel structure includes a horizontally arranged support substrate 3. The support substrate 3 extends vertically upward on both sides in the width direction to form limiting side plates 4. The first slide guide channel 1 is continuously bent from the top of the limiting side plates 4, including an outwardly horizontally extending guide slide 11 and an upwardly extending lateral limiting flange 12. The slide moves along the guide slide 11 under the drive of the first actuating component 2, and is prevented from radial displacement by the constraint of the lateral limiting flange 12.

[0033] The one-piece molded metal guide channel structure design ensures overall rigidity and avoids glass slide jamming caused by deformation.

[0034] As shown in Figure 3, the first actuating component 2 includes a first actuating member 21 for pushing the glass slide and a first translation module for driving the first actuating member 21 to move laterally. The first translation module includes a lateral drive motor 22 and a synchronous transmission component disposed between the first actuating member 21 and the lateral drive motor 22.

[0035] The supporting base plate 3 is provided with a mounting plate 5, the mounting surface of which is perpendicular to the supporting base plate 3. The transverse drive motor 22 is disposed on the mounting surface of the mounting plate 5. The synchronous transmission assembly includes a drive wheel 23, an idler wheel 24, and a synchronous belt 25. The drive wheel 23 and the idler wheel 24 are connected by the synchronous belt 25 and are spaced apart on the mounting surface along the conveying direction. The drive wheel 23 is coaxially connected to the output shaft of the transverse drive motor 22.

[0036] In this embodiment, a tensioning wheel 26 is also provided between the drive wheel 23 and the idler wheel 24. The two sets of tensioning wheels 26 act on the two parallel sections of the synchronous belt 25 respectively to maintain the preset tension of the synchronous belt 25.

[0037] The first translation module also includes a first linear guide rail 27 extending in the same direction as the conveying direction. The first linear guide rail 27 is disposed on the top of the mounting plate 5. When the transverse drive motor 22 is started, the synchronous belt 25 reciprocates in a cyclical motion, driving the first actuating member 21 to reciprocate along the conveying direction.

[0038] Specifically, as shown in Figure 4, the first actuating member 21 includes a transmission part 211 fixedly connected to one of the parallel segments of the timing belt 25, a glass pushing part 212 whose glass pushing end face contacts the glass slide, and a connecting part 213 for connecting the transmission part 211 and the glass pushing part 212. The connecting part 213 is slidably connected to the first linear guide rail 27 by a slider.

[0039] The second slide guide groove 6 extends longitudinally. In this embodiment, the second slide guide groove 6 adopts a central turntable structure to connect with the first slide guide groove 1. The second slide guide groove 6 includes a bearing portion 61 on both sides of the central turntable along the lateral direction and a guide surface 62 adapted to the lateral edges of the slide. The guide surface 62 is used to constrain the lateral movement of the slide. The guide surface 62 on the feed side of the central turntable is provided with a receiving slot 621 that is horizontally aligned with the guide slide 11 of the first slide guide groove 1, ensuring that the slide can smoothly transition to the second slide guide groove 6. The guide surface 62 on the opposite side is provided with an upwardly extending limiting platform 622. The top height of the limiting platform 622 is higher than the bearing surface of the guide slide 11, preventing the slide from detaching from the central turntable during the transfer from the first slide guide groove 1 to the second slide guide groove 6.

[0040] As shown in Figure 5, the second actuating assembly 7 includes a second actuating member 71 for pushing the glass slide to move longitudinally and a second translation module for driving the second actuating member 71 to move laterally. The first translation module includes a longitudinal drive motor and a second linear guide rail 72 extending longitudinally. The second actuating member 71 is slidably connected to the second linear guide rail 72 under the drive of the longitudinal drive motor.

[0041] Specifically, the bottom of the turntable is provided with a support structure 8, which is fixedly connected to the metal guide groove structure. The second actuating member 71 includes a driving part 711 fixedly connected to the slider of the second linear guide rail 72 and an execution part 712 whose glass pushing end face contacts the glass slide.

[0042] Furthermore, it also includes a positioning module 9, which includes a lateral position detection component and a longitudinal position detection component. The lateral position detection component includes a first detection unit 91 and a second detection unit 92 located at the beginning and end of the lateral conveying direction, and the longitudinal position detection component includes a third detection unit 93 located at the beginning of the longitudinal conveying direction. The first actuating member 21 is provided with a first signal trigger 94 that cooperates with the first detection unit 91 and the second detection unit 92, and the second actuating member 71 is provided with a second signal trigger 95 that cooperates with the third detection unit 93.

[0043] When the first actuating element 21 pushes the glass slide to the end along the transverse conveying direction, the second detection unit 92 detects the first signal trigger 94 and generates a transverse positioning signal for the glass slide; after receiving the corresponding signal, the control circuit triggers the longitudinal drive motor to start, driving the second actuating element 71 to push the glass slide to move along the longitudinal conveying direction.

[0044] In this embodiment, a glass slide support plate 10 is provided at the first end of the transverse conveying system along the transverse conveying direction. The glass slide support plate 10 is located between the limiting side plates 4 on both sides of the bearing substrate 3, and its two side edges form a glass pushing channel with the inner sidewall of the limiting side plate 4 respectively. The upper surface of the glass slide support plate 10 is coplanar with the guide slide 11 of the first glass slide guide groove 1 to ensure that the transverse conveying system smoothly connects to the glass slide on the incoming side. A pushing notch 214 is provided in the middle area of ​​the pushing part 212 of the first actuating member 21, forming the first actuating member 21 for simultaneously abutting the two side segmented surfaces of the glass slide. The width of the pushing notch 214 is greater than the width of the glass slide support plate 10, so as to completely avoid the glass slide support plate 10 during the movement of the first actuating member 21. The segmented surfaces on both sides of the pushing notch 214 simultaneously contact the two ends of the glass slide to achieve force-balanced pushing.

[0045] When the first actuating element 21 is reset or passes the glass slide support plate 10, the segmented surfaces on both sides move within the glass pushing channel without interfering with the glass slide support plate 10, thereby achieving unobstructed reciprocating motion.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
