Description

Technical Field

[0001] This invention relates to a pressing device, and more specifically to a pressing device for thermoelectric separation of aluminum substrates. Background Technology

[0002] Pressing and leveling devices for thermoelectric separation metal substrates are commonly used in the manufacture of thermoelectric materials, which are typically composed of multiple layers of metal or alloy and are used to convert heat energy and electrical energy using the thermoelectric effect. According to a disclosed pressing and leveling device for nylon fabric processing (Publication No.: CN214782679U), the device includes a main body comprising a pressing and leveling device, a transmission belt, a connecting line, a control box, and a push rod controller. The transmission belt is located inside the pressing and leveling device. A connecting line is located on the right side of the pressing and leveling device, and a cable management mechanism is located outside the connecting line. The connecting line is inserted into a first slot, and the outer side of the first slot is located within a first outer shell. The side of the first outer shell closest to the pressing and leveling device is fixedly connected to the pressing and leveling device.

[0003] One of the goals of the lamination and leveling process is to improve the thickness and performance of the metal substrate to meet product quality requirements. If the lamination process is uneven, it will lead to unevenness or wavy surfaces, affecting the thickness and performance of the metal substrate. Through the cooperation of the lamination and leveling device, transmission belt, connecting line and other components mentioned above, it is difficult to avoid unevenness of the metal substrate during the lamination process, making it difficult to ensure the consistency of the thickness and performance of each metal substrate. Furthermore, when using the equipment to laminate the aluminum substrate, the lack of limiting during the lamination process causes the aluminum substrate to shift during lamination, thus affecting the lamination effect.

[0004] Therefore, the inventors designed a pressing device for thermoelectric separation of aluminum substrates. Summary of the Invention

[0005] The main objective of this disclosure is to provide a pressing apparatus for thermoelectric separation of aluminum substrates, so as to effectively solve the problems raised by the inventors in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A pressing device for thermoelectric separation of aluminum substrates includes a pressing worktable. Two parallel lifting gantry frames are fixedly mounted on the top of the pressing worktable. A pressing plate is movably mounted below the left lifting gantry frame, and the pressing plate moves vertically. Two parallel directional slide rails are fixedly mounted on the top of the pressing worktable, and a transverse rail and a pressure plate positioning groove are slidably mounted between the two directional slide rails. The transverse rail is located to the lower right of the pressing plate, and the pressure plate positioning groove is located to the lower left of the pressing plate. The pressure plate positioning groove is used to fix the aluminum substrate to be processed. The pressure plate positioning groove and the transverse rail are connected by an elastic linkage component, and both move horizontally.

[0007] Preferably, two front-to-back support seats are fixedly installed inside the positioning groove of the pressure plate, and a linear rod is slidably installed through each of the two support seats. Front and rear pressure plates are fixedly connected to the ends of the two linear rods that are close to each other, and an external force hemisphere is fixedly connected to the other ends of the two linear rods. Two parallel smooth linear force strips are fixedly installed on the top of the pressing worktable, and the spherical end of the external force hemisphere slides in contact with the smooth linear force strips. A reset spring is fixedly connected between the external force hemisphere and the positioning groove of the pressure plate, i.e., the reset spring is sleeved on the linear rod. The pressure plate... The positioning groove is located between two smooth straight force-bearing bars. A second straight rod is slidably installed through the right side of the positioning groove. A side pressure plate and a pressing blocking key are fixedly installed at both ends of the second straight rod. The side pressure plate is located inside the positioning groove and between the two front and rear pressure plates. The pressing blocking key is located outside the positioning groove. A second reset spring is fixedly connected between the pressing blocking key and the right side of the positioning groove. That is, the second reset spring is sleeved on the second straight rod. A first limiting block is fixedly installed on the top of the pressing worktable and is located to the right of the pressing blocking key.

[0008] Preferably, an extension blocking key is fixedly connected to the side of the support base near the smooth linear force-bearing strip, a second limiting block is fixedly installed on the smooth linear force-bearing strip, and the extension blocking key is located between the second limiting block and the external force hemisphere. A soft cleaning brush is bonded to the end of the extension blocking key away from the positioning groove of the pressure plate, and the soft cleaning brush is in contact with the smooth linear force-bearing strip.

[0009] Preferably, the elastic linkage component includes a groove connecting rod, a parallel block, and a compression spring. The groove connecting rod is fixedly connected to the right side of the positioning groove of the pressure plate. The transverse rail is slidably sleeved on the groove connecting rod, and the right end of the groove connecting rod is fixedly connected to the parallel block. A compression spring is fixedly connected between the parallel block and the transverse rail, i.e., the compression spring is sleeved on the groove connecting rod. The length between the parallel block and the transverse rail is a, the length between the extension blocking key and the second limiting block is b, and the length between the compression blocking key and the first limiting block is c, where a>b>c.

[0010] Preferably, a lifting slide is slidably installed on the left lifting gantry, and an anti-detachment block is fixedly connected to the upper end of the side of the lifting slide. A Z-axis rack is fixedly connected to the rear side of the lifting slide, and the Z-axis rack movably passes through the left lifting gantry. Mounting blocks are fixedly installed on both lifting gantry, and an X-axis transmission rod is rotatably installed between the two mounting blocks. A second sprocket is fixedly connected to the left end of the X-axis transmission rod, and the second sprocket meshes with the Z-axis rack.

[0011] Preferably, the top of the pressing worktable is provided with a sliding groove, and a displacement seat is slidably installed in the sliding groove. The transverse rail is fixedly connected to the top of the displacement seat. A linear one-way screw is rotatably installed in the sliding groove, and the displacement seat is threaded onto the linear one-way screw. A servo motor is fixedly installed on the right side of the pressing worktable, and the output end of the servo motor is fixedly connected to the linear one-way screw. The first limit block spans the sliding groove. A first spur gear is fixedly installed on the right side of the one-way screw, and a third spur gear is fixedly installed on the right side of the X-axis transmission rod, and the third spur gear meshes with the first spur gear.

[0012] In view of this, compared with the prior art, the beneficial effects of the present invention are: (i) In this application, during the pressing operation, the servo motor is started, which drives the linear unidirectional lead screw to rotate, causing the displacement seat to move to the right along the slide rail. The slide rail slides to the right on the groove connecting rod. Under the elastic resistance of the compression spring and the parallel block, the groove connecting rod moves together with the slide rail and slides to the right with the pressure plate positioning groove. The directional slide rail can ensure the consistency of the sliding direction. During the movement, under the support of the smooth linear force bar, the external force hemisphere is compressed and drives the first linear rod to move. The first reset spring is compressed, and the two front and rear pressure plates move towards each other to clamp the aluminum substrate to be processed. When the extrusion blocking key moves to the right, it will touch the first limit block. Under the block of the first limit block, the second linear rod drives the side pressure plate to move, and the second reset spring is compressed so that the side pressure plate can further clamp the aluminum substrate to be processed, thereby improving the positioning effect of the aluminum substrate before processing.

[0013] (ii) In this application, during the process of the positioning groove of the pressure plate moving to the right, the extension blocking key moves along with it. The soft cleaning brush cleans the smooth straight force strip in advance to remove dust and other particulate impurities, so that the movement of the external force hemisphere is more stable, and thus the external force on the aluminum substrate can remain stable.

[0014] (iii) In this application, until the pressure plate positioning groove slides to the far right, the second limiting block restricts the extension blocking key, and the two abut against each other, thereby causing the pressure plate positioning groove to stop moving. At this time, the aluminum substrate fixed in the pressure plate positioning groove is located directly below the pressing plate, which is the processing area. Since b>c, before the pressure plate positioning groove is restricted from moving, the extrusion blocking key has already contacted the first limiting block, thereby ensuring that the aluminum substrate is fixed when it moves to the processing area.

[0015] (iv) In this application, since the linear one-way screw is still rotating, the transverse rail will continue to move after the positioning groove of the pressure plate stops. At this time, the compression spring is in a compressed state. The linear one-way screw drives the first spur gear to rotate. In the meshing transmission action with the third spur gear, the X-axis transmission rod drives the second spur gear to rotate. Then the Z-axis rack drives the lifting slide to move downward, that is, the transverse rail moves to the right and the lifting slide moves downward, so that the pressing plate presses the stationary aluminum substrate, ensuring the uniformity of pressing, and the automated operation is stable, safe and reliable.

[0021] Specifically, the elastic linkage component includes a groove connecting rod 401, a parallel block 402, and a compression spring 403. The groove connecting rod 401 is fixedly connected to the right side of the positioning groove 5 of the pressure plate.

[0022] Specifically, a lifting slide 201 is slidably installed on the lifting gantry 2 on the left side, and an anti-detachment block is fixedly connected to the upper end of the side of the lifting slide 201. A Z-axis rack 202 is fixedly connected to the rear side of the lifting slide 201, and the Z-axis rack 202 moves through the lifting gantry 2 on the left side.

A second spur gear 205 is fixedly connected to the left end of the X-axis transmission rod 204, and the second spur gear 205 meshes with the Z-axis rack 202.

[0023] Specifically, the top of the pressing worktable 1 is provided with a sliding groove, and a displacement seat is slidably installed in the sliding groove. The transverse rail 4 is fixedly connected to the top of the displacement seat. A linear one-way screw 105 is rotatably installed in the sliding groove, and the displacement seat is threaded onto the linear one-way screw 105. A servo motor 107 is fixedly installed on the right side of the pressing worktable 1, and the output end of the servo motor 107 is fixedly connected to the linear one-way screw 105.

[0024] The specific implementation method of this embodiment is as follows: the aluminum substrate to be processed is placed in the pressure plate positioning groove 5, that is, it is located between the two front and rear pressure plates 503, the side pressure plate 506, and the side groove of the pressure plate positioning groove 5. During the pressing process, the servo motor 107 is activated, driving the linear unidirectional lead screw 105 to rotate. This causes the displacement seat to move to the right along the slide rail 4, which in turn moves the transverse rail 4. The transverse rail 4 slides to the right on the groove connecting rod 401. Under the elastic resistance of the compression spring 403 and the parallel block 402, the groove connecting rod 401 moves together with the transverse rail 4, carrying the pressure plate positioning groove 5 to slide to the right. The directional slide rail 101 ensures the consistency of the sliding direction. During the movement, supported by the smooth linear force bar 103, the external force is partially neutralized. When the ball 504 is pressed, it drives the first linear rod 502 to move, and the first reset spring 505 is compressed. Then the two front and rear pressure plates 503 move towards each other to clamp the aluminum substrate to be processed. When the pressing blocking key 507 moves to the right, it will touch the first limit block 102. Under the obstruction of the first limit block 102, the second linear rod drives the side pressure plate 506 to move, and the second reset spring 508 is compressed so that the side pressure plate 506 can further clamp the aluminum substrate to be processed, thereby improving the positioning effect of the aluminum substrate before processing. As the pressure plate positioning groove 5 moves to the right, the extended blocking key 509 moves along with it. The soft cleaning brush 6 cleans the smooth straight force strip 103 in advance to remove dust and other particulate impurities, making the movement of the external force hemisphere 504 more stable, and thus keeping the external force on the aluminum substrate stable. Until the pressure plate positioning groove 5 slides to the far right, the second limiting block 104 restricts the extension blocking key 509, and the two abut against each other, causing the pressure plate positioning groove 5 to stop moving. At this time, the aluminum substrate fixed in the pressure plate positioning groove 5 is located directly below the pressing plate 3, which is the processing area. Since b>c, before the pressure plate positioning groove 5 is restricted from moving, the pressing blocking key 507 has already contacted the first limiting block 102, thereby ensuring that the aluminum substrate is fixed when it moves to the processing area. Since the linear one-way lead screw 105 is still rotating, the transverse rail 4 will continue to move after the pressure plate positioning groove 5 comes to a stop. At this time, the compression spring 403 is in a compressed state. The linear one-way lead screw 105 drives the first sprocket 106 to rotate. In the meshing transmission action with the third sprocket 206, the X-axis transmission rod 204 drives the second sprocket 205 to rotate. Then, the Z-axis rack 202 drives the lifting slide 201 to move downward. That is, the transverse rail 4 moves to the right and the lifting slide 201 moves downward, so that the pressing plate 3 presses the stationary aluminum substrate (there is sufficient height between the pressing plate 3 and the pressure plate positioning groove 5 so that when the pressure plate positioning groove 5 is stationary, the pressing plate 3 is still above it, avoiding motion interference). The automated operation is stable, safe and reliable.
