Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0034] In related technologies, a mechanical device includes a base and a movable part that can be movably mounted on the base. The range of motion of the movable part is limited by the size of the base. To allow the movable part to have a larger range of motion, the size of the base is often increased. However, this makes the mechanical device too large, which is not conducive to the assembly of the mechanical device. Furthermore, due to the limitation of the assembly space, it also directly affects the applicable scenarios of the mechanical device, thereby affecting the practicality of the mechanical device.
[0035] Based on this, this application proposes a dual-stroke reciprocating drive module 50, in which the second movable plate 53 has a large range of motion, and the dual-stroke reciprocating drive module 50 is small in size, can be well assembled, and is highly practical.
[0036] The following is for reference. Figures 1-4 This invention describes a dual-stroke reciprocating drive module 50 according to an embodiment of the present invention.
[0037] like Figures 1-2 As shown, the dual-stroke reciprocating drive module 50 according to an embodiment of the present invention includes a base plate 51, a first movable plate 52, a second movable plate 53, an active component 54, and a driven component 55. The first movable plate 52 is movably mounted on the base plate 51 along a first direction, and the second movable plate 53 is movably mounted on the first movable plate 52 along the first direction. The active component 54 is mounted on the base plate 51 and is used to drive the first movable plate 52 to move. The driven component 55 is mounted on one side of the first movable plate 52 in a second direction, and the driven component 55 includes a first transmission wheel 551, a second transmission wheel 552, and a drive wheel 553. A drive belt 553 is mounted on a first movable plate 52 with a first drive wheel 551 and a second drive wheel 552 spaced apart along a first direction. The drive belt 553 is sleeved on the first drive wheel 551 and the second drive wheel 552 and is positioned between the first drive wheel 551 and the second drive wheel 552. The drive belt 553 has a first segment 5531 and a second segment 5532 that are parallel and spaced apart along a third direction. The base plate 51 is provided with a first clamping member 56, and the second movable plate 53 is provided with a second clamping member 57. The first clamping member 56 clamps the first segment 5531, and the second clamping member 57 clamps the second segment 5532.
[0038] Reference Appendix Figure 1 and Figure 2 As shown in a specific example, the first direction can be referenced to the left and right direction, the second direction can be referenced to the front and back direction, and the third direction can be referenced to the up and down direction. The base plate 51, the first movable plate 52 and the second movable plate 53 are all plates extending in the left and right direction. The dual-stroke reciprocating drive module 50 has a first state and a second state. In the first state, the first movable plate 52 and the second movable plate 53 are both located at the rightmost end of the stroke. At this time, the base plate 51, the first movable plate 52 and the second movable plate 53 are stacked in the up and down direction. At this time, the volume of the dual-stroke reciprocating drive module 50 is relatively small.
[0039] When the dual-stroke reciprocating drive module 50 switches from the first state to the second state, the active component 54 drives the first movable plate 52 to move from right to left on the base plate 51. Since the driven component 55 is mounted on the first movable plate 52, the first transmission wheel 551 and the second transmission wheel 552 are spaced apart in the left-right direction, and the transmission belt 553 is wrapped around them, forming a first segment 5531 and a second segment 5532 that are parallel and spaced apart in the up-down direction. The first clamping member 56 of the base plate 51 clamps the first segment 5531, and the second clamping member 57 of the second movable plate 53 clamps the second segment 5532. When the first movable plate 52 moves, through the cooperation of the transmission belt 553 with the first clamping member 56 and the second clamping member 57, the second movable plate 53 can also be driven to move from right to left, and the second movable plate 53 can also have a certain displacement relative to the first movable plate 52, thereby achieving a larger range of motion for the second movable plate 53. The principle is to use the active component 54 to drive the first movable plate 52 to move, and then, with the help of the linkage between the transmission belt 553 in the driven component 55 and the first clamping member 56 and the second clamping member 57, the second movable plate 53 can further expand its movement space based on the movement of the first movable plate 52. While ensuring that the second movable plate 53 has a large range of motion, the overall module size is small, which is convenient for assembly and not too restricted by assembly space. This greatly enhances the practicality of the dual-stroke reciprocating drive module 50 in various scenarios and can be widely used in various mechanical devices with requirements for range of motion and limited space.
[0040] Similarly, when the dual-stroke reciprocating drive module 50 switches from the second state to the first state, the active component 54 drives the first movable plate 52 to move from left to right on the base plate 51. The specific working principle has been described above and will not be repeated here.
[0041] Furthermore, it should be noted that when the active component 54 drives the first movable plate 52 to move relative to the base plate 51 at a speed of V, the driven component 55 causes the second movable plate 53 to also move relative to the first movable plate 52 at a speed of V. As a result, the movement speed of the second movable plate 53 relative to the base plate 51 is 2V, which allows the second movable plate 53 to obtain a higher movement speed, thereby improving the operating efficiency of the dual-stroke reciprocating drive module 50.
[0042] Therefore, according to the dual-stroke reciprocating drive module 50 of this utility model embodiment, by setting the driven component 55, when the active component 54 drives the first movable plate 52 to move along the first direction, the second movable plate 53 can also move along the first direction on the first movable plate 52, thereby making the second movable plate 53 have a larger range of motion, and the second movable plate 53 moves at a faster speed, which can improve the operating efficiency of the dual-stroke reciprocating drive module 50.
[0043] In the above example, combined Figure 1 and Figure 2 As can be seen, in the first direction, the dimensions of the first movable plate 52 and the second movable plate 53 are basically the same, with the first movable plate 52 being slightly smaller than the second movable plate 53.
[0044] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the active component 54 includes a drive motor 541, a lead screw 542, and a nut 543. The drive motor 541 is mounted on the base plate 51, the lead screw 542 is rotatably mounted on the base plate 51, the end of the lead screw 542 is connected to the drive motor 541 for transmission, and the nut 543 is sleeved on the lead screw 542 and fixedly connected to the first movable plate 52.
[0045] In other words, in the active component 54, the drive motor 541 serves as the power source, mounted on the base plate 51 to provide power for the entire movement. The lead screw 542 is rotatably mounted on the base plate 51 and is connected to the drive motor 541. When the drive motor 541 starts, it drives the lead screw 542 to rotate. The nut 543 is fitted onto the lead screw 542 and fixedly connected to the first movable plate 52. Due to the transmission characteristics of the lead screw 542 and nut 543, the rotational motion of the lead screw 542 is converted into the linear motion of the nut 543, thereby driving the first movable plate 52 to move along the first direction. The lead screw 542 and nut 543 have high transmission efficiency, effectively converting the rotational power of the drive motor 541 into the linear motion required by the first movable plate 52, thus improving the stability of the first movable plate 52's movement. Furthermore, the lead screw 542 and nut 543 transmission has self-locking properties. When the drive motor 541 stops working, the first movable plate 52 can remain stably in its current position, preventing positional deviation due to external forces or other factors, thereby improving the safety and reliability of the equipment operation. Furthermore, the active component 54 has a relatively simple and compact structure, which facilitates installation and layout in a limited space, and is conducive to the miniaturization design and assembly of the entire dual-stroke reciprocating drive module 50.
[0046] In some embodiments of this utility model, such as Figures 2-4 As shown, the first movable plate 52 is provided with a lead screw groove 521, which has a first opening 5211 opposite to the lead screw 542, so that the lead screw 542 can be housed in the lead screw groove 521 when the first movable plate 52 moves in the first direction.
[0047] In other words, the lead screw groove 521 provides storage space for the lead screw 542. When the first movable plate 52 moves along the first direction, the lead screw 542 can be stored in it, effectively reducing the space occupied by the active component 54, and thus reducing the space occupied by the dual-stroke reciprocating drive module 50, which helps to make the structure of the dual-stroke reciprocating drive module 50 more compact. Secondly, this storage design can protect the lead screw 542 to a certain extent, reducing the risk of damage or reduced accuracy caused by external collisions, dust and other factors, thereby extending the service life of the lead screw 542, ensuring the stable operation of the drive component and even the entire module, and reducing the maintenance cost and frequency of the equipment.
[0048] In some embodiments of this utility model, such as Figures 2-4 As shown, in the second direction, the lead screw groove 521 is located in the middle of the first movable plate 52, and the lead screw groove 521 also has a second opening 5212 facing the bottom plate 51. In the first direction, the second opening 5212 is equal in length to the lead screw groove 521.
[0049] In other words, in the second direction, setting the lead screw groove 521 in the middle of the first movable plate 52 helps to achieve a uniform distribution of force on the first movable plate 52, making the first movable plate 52 more stable during movement, reducing adverse phenomena such as tilting and jamming caused by uneven force, and improving the accuracy and smoothness of movement. At the same time, the lead screw groove 521 has a second opening 5212 facing the base plate 51, and its length in the first direction is equal to that of the lead screw groove 521. This not only facilitates the installation and adjustment of the lead screw 542, but also allows the lead screw 542 to be connected and positioned with components such as the nut 543 through this opening during assembly, which helps to ensure the long-term stable and efficient operation of the dual-stroke reciprocating drive module 50.
[0050] In some embodiments of this utility model, such as Figures 2-4 As shown, the lead screw groove 521 is provided with a through groove 522 that penetrates the first movable plate 52 at one end facing the drive motor 541. The through groove 522 extends to the end of the first movable plate 52 so that the through groove 522 has a third opening facing the motor. The active component 54 also includes a fixing block 544. A nut 543 is installed on the fixing block 544 and extends at least partially into the through groove 522.
[0051] In other words, the through slot 522 provides installation space for the nut 543 and the fixing block 544. The combined installation of the fixing block 544 and the nut 543 enhances the stability of the connection between the nut 543 and the first movable plate 52. During the movement of the first movable plate 52 with the lead screw 542, it can effectively prevent the nut 543 from loosening or shifting, ensuring the accuracy and reliability of the transmission. Moreover, the opening design of the through slot 522 facing the drive motor 541 facilitates the positioning and installation of the nut 543 and the fixing block 544 during assembly, improving assembly efficiency. It also provides convenience for later maintenance and repair, allowing for relatively convenient inspection, adjustment, or replacement of key transmission components such as the nut 543.
[0052] In some embodiments of this utility model, such as Figures 2-4 As shown, the base plate 51 is provided with two first slide rails 511, and the first movable plate 52 is provided with two first sliders 523 on the side facing the base plate 51. The two first sliders 523 respectively cooperate with the two first slide rails 511. In the second direction, the two first sliders 523 are respectively located on both sides of the lead screw groove 521. And / or, the second movable plate 53 is provided with two second slide rails 531, and the first movable plate 52 is provided with two second sliders 524 on the side facing the second movable plate 53. The two second sliders 524 respectively cooperate with the two second slide rails 531. In the second direction, the two second slide rails 531 are respectively located on both sides of the lead screw groove 521.
[0053] In other words, between the base plate 51 and the first movable plate 52, two first sliders 523 are located on both sides of the lead screw groove 521 and cooperate with two first slide rails 511. When the first movable plate 52 moves along the first direction, they can provide stable guidance and support, ensuring the accuracy of the motion trajectory and effectively preventing the first movable plate 52 from deviating, swaying, or other unstable situations, thus improving the stability and reliability of the entire module's movement. Similarly, between the first movable plate 52 and the second movable plate 53, two second slide rails 531 are located on both sides of the lead screw groove 521 and cooperate with second sliders 524. This ensures the smoothness and accuracy of the movement of the second movable plate 53 relative to the first movable plate 52, and also allows the force to be evenly transmitted between the two, reducing local stress concentration and further optimizing the mechanical performance of the dual-stroke reciprocating drive module 50. Moreover, this layout structure is compact, making full use of space and facilitating the miniaturization design and efficient assembly of the module.
[0054] In some embodiments of this utility model, such as Figures 2-4 As shown, in the first direction, the first slider 523 and the second slider 524 are respectively disposed at both ends of the first movable plate 52.
[0055] like Figures 2-4 As shown, the first slider 523 is located at the right end of the lower surface of the first movable plate 52, and the second slider 524 is located at the left end of the upper surface of the first movable plate 52. There are four first sliders 523, arranged in pairs on both sides of the lead screw groove 521. Similarly, there are four second sliders 524, arranged in pairs on both sides of the lead screw groove 521. Thus, when the double-stroke reciprocating drive module 50 is in its first state, the second movable plate 53, the second slider 524, the first movable plate 52, the first slider 523, and the base plate 51 form an S-shaped structure in the downward direction. In the second state, the first movable plate 52 can be well supported between the second movable plate 53 and the base plate 51. The second movable plate 53 has a second slide rail 531, which can effectively improve the structural strength of the second movable plate 53. The base plate 51 has a first slide rail 511, which can effectively improve the structural strength of the base plate 51. Therefore, when structural components that need to move through the double-stroke reciprocating drive module 50 are installed on the second movable plate 53, the double-stroke reciprocating drive module can effectively support the structural components and has good stability through the above structural design.
[0056] In some embodiments of this utility model, such as Figures 1-4As shown, the dual-stroke reciprocating drive module 50 further includes: a first limiting component 61 and a second limiting component 62. Both the first limiting component 61 and the second limiting component 62 are located on the side of the first movable plate 52 facing the driven component 55. The first limiting component 61 includes a first photoelectric sensor 611 and a first trigger 612. The first photoelectric sensor 611 is mounted on the base plate 51, and the first trigger 612 is mounted on the first movable plate 52. The second limiting component 62 includes a second photoelectric sensor 621 and a second trigger 622. The second photoelectric sensor 621 is mounted on the base plate 51, and the second trigger 622 is mounted on the first movable plate 52. The first photoelectric sensor 611 and the second photoelectric sensor 621 are spaced apart along a first direction.
[0057] Reference Appendix Figures 1-4 In one example, in the left-right direction, a first photoelectric sensor 611 is mounted on the right end of the base plate 51, and a second photoelectric sensor 621 is mounted on the left end of the base plate 51 and can be mounted on a first clamping member 56 on the base plate 51. A first trigger member 612 can be mounted on the right end of the first movable plate 52. When the first movable plate 52 moves from left to right, the first trigger member 612 is sensed by the first photoelectric sensor 611, and the drive motor 541 stops driving the first movable plate 52. Further, the second trigger member 622 can be mounted on the right end of the first movable plate 52, and the second trigger member 622 is located to the left of the first trigger member 612. When the first movable plate 52 moves from right to left, the second trigger member 622... If the trigger 622 can be detected by the second photoelectric sensor 621, the drive motor 541 will stop driving the first movable plate 52. Thus, the first limiting component 61 and the second limiting component 62 can effectively limit the range of movement of the first movable plate 52 in the left and right directions. Similarly, when the first movable plate 52 moves, the second movable plate 53 can also move. When the first movable plate 52 stops moving, the enemy movable plate also stops moving. Therefore, the first limiting component 61 and the second limiting component 62 can also effectively limit the range of movement of the second movable plate 53 in the left and right directions, and can effectively prevent the first movable plate 52 and the second movable plate 53 from moving beyond their range and interfering with other components.
[0058] The first limiting component 61 and the second limiting component 62 in the above example can also be provided by other sensors or limiting structures, and this application does not impose any restrictions.
[0059] In some embodiments of this utility model, both the first transmission wheel 551 and the second transmission wheel 552 are provided with a first toothed structure, and the transmission belt 553 is provided with a second toothed structure that meshes with the first toothed structure. This improves the transmission efficiency between the first transmission wheel 551 and the transmission belt 553, as well as between the second transmission wheel 552 and the transmission belt 553.
[0060] In some embodiments of this utility model, multiple weight-reduction holes are provided on the base plate 51, the first movable plate 52, and the second movable plate 53. This effectively reduces the weight of the dual-stroke reciprocating drive module 50.
[0061] like Figures 1-4 In a specific example shown, the weight-reducing hole on the base plate 51 is the first weight-reducing hole 512, which is a square hole.

[0062] The following is for reference. Figures 1-4 This invention describes the structure and operation of a dual-stroke reciprocating drive module 50 according to a specific embodiment of the present invention.
[0063] The dual-stroke reciprocating drive module 50 includes a base plate 51, a first movable plate 52, a second movable plate 53, a driving component 54, and a driven component 55. The first movable plate 52 is movably mounted on the base plate 51 along a first direction, and the second movable plate 53 is movably mounted on the first movable plate 52 along the first direction. The driving component 54 is mounted on the base plate 51 and is used to drive the first movable plate 52 to move. The driven component 55 is mounted on one side of the first movable plate 52 in a second direction and includes a first transmission wheel 551, a second transmission wheel 552, and a transmission belt 553. The first drive wheel 551 and the second drive wheel 552 are spaced apart on the first movable plate 52 along a first direction. The drive belt 553 is wrapped around the first drive wheel 551 and the second drive wheel 552 and is located between the first drive wheel 551 and the second drive wheel 552. The drive belt 553 has a first segment 5531 and a second segment 5532 that are parallel and spaced apart along a third direction. The base plate 51 is provided with a first clamping member 56, and the second movable plate 53 is provided with a second clamping member 57. The first clamping member 56 clamps the first segment 5531, and the second clamping member 57 clamps the second segment 5532.
[0064] The active component 54 includes a drive motor 541, a lead screw 542, and a nut 543. The drive motor 541 is mounted on the base plate 51, the lead screw 542 is rotatably mounted on the base plate 51, the end of the lead screw 542 is connected to the drive motor 541 for transmission, and the nut 543 is sleeved on the lead screw 542 and fixedly connected to the first movable plate 52.
[0065] The first movable plate 52 is provided with a lead screw groove 521, which has a first opening 5211 opposite to the lead screw 542, so that the lead screw 542 can be housed in the lead screw groove 521 when the first movable plate 52 moves in a first direction.
[0066] In the second direction, the lead screw groove 521 is located in the middle of the first movable plate 52, and the lead screw groove 521 also has a second opening 5212 facing the bottom plate 51. In the first direction, the second opening 5212 is equal in length to the lead screw groove 521.
[0067] The lead screw groove 521 is provided with a through groove 522 that passes through the first movable plate 52 at one end facing the drive motor 541. The through groove 522 extends to the end of the first movable plate 52 so that the through groove 522 has an opening facing the motor as a third opening. The active component 54 also includes a fixing block 544. A nut 543 is installed on the fixing block 544 and extends at least partially into the through groove 522.
[0068] The base plate 51 is provided with two first slide rails 511, and the first movable plate 52 is provided with two first sliders 523 on the side facing the base plate 51. The two first sliders 523 respectively cooperate with the two first slide rails 511. In the second direction, the two first sliders 523 are respectively located on both sides of the lead screw groove 521. The second movable plate 53 is provided with two second slide rails 531, and the first movable plate 52 is provided with two second sliders 524 on the side facing the second movable plate 53. The two second sliders 524 respectively cooperate with the two second slide rails 531. In the second direction, the two second slide rails 531 are respectively located on both sides of the lead screw groove 521.
[0069] In the first direction, the first slider 523 and the second slider 524 are respectively disposed at both ends of the first movable plate 52.
[0070] The dual-stroke reciprocating drive module 50 further includes: a first limiting component 61 and a second limiting component 62. Both the first limiting component 61 and the second limiting component 62 are located on the side of the first movable plate 52 facing the driven component 55. The first limiting component 61 includes a first photoelectric sensor 611 and a first trigger 612. The first photoelectric sensor 611 is mounted on the base plate 51, and the first trigger 612 is mounted on the first movable plate 52. The second limiting component 62 includes a second photoelectric sensor 621 and a second trigger 622. The second photoelectric sensor 621 is mounted on the base plate 51, and the second trigger 622 is mounted on the first movable plate 52. The first photoelectric sensor 611 and the second photoelectric sensor 621 are spaced apart along a first direction.
[0071] Multiple weight-reduction holes are provided on the base plate 51, the first movable plate 52, and the second movable plate 53.
[0072] When the dual-stroke reciprocating drive module 50 is working, the drive motor 541 in the active component 54 is first started, driving the lead screw 542 to rotate. Since the nut 543 is sleeved on the lead screw 542 and fixedly connected to the first movable plate 52, and the first movable plate 52 cooperates with the first slide rail 511 on the base plate 51 via the first slider 523, the first movable plate 52 slides smoothly on the base plate 51 along the first direction under the transmission action of the lead screw 542 and the nut 543. During this process, the lead screw 542 is housed in the lead screw groove 521 of the first movable plate 52. The opening design of the lead screw groove 521 ensures the normal operation of the lead screw 542, makes reasonable use of space, and protects the lead screw 542.
[0073] When the first movable plate 52 moves, it drives the first transmission wheel 551 and the second transmission wheel 552 of the driven assembly 55 mounted on it to move. Because the transmission belt 553 is wrapped around the first transmission wheel 551 and the second transmission wheel 552, and its first section 5531 is clamped by the first clamping member 56 of the base plate 51, and its second section 5532 is clamped by the second clamping member 57 of the second movable plate 53, the movement of the first movable plate 52 will drive the second movable plate 53 to move relative to the first movable plate 52 in the first direction through the transmission belt 553. The second movable plate 53 achieves stable movement by relying on the second slider 524 to cooperate with the second slide rail 531 on the first movable plate 52, thereby allowing the second movable plate 53 to obtain a larger range of motion.
[0074] During the movement of the first movable plate 52, the first limiting component 61 and the second limiting component 62 located on the side of the first movable plate 52 facing the driven component 55 function. When the first trigger 612 on the first movable plate 52 moves to the position corresponding to the first photoelectric sensor 611 on the base plate 51, the first photoelectric sensor 611 is triggered and can send a signal to the control system. The control system decides whether to stop, reverse the drive motor 541, etc., according to the preset program. Similarly, the second trigger 622 cooperates with the second photoelectric sensor 621 to perform a similar limiting function. The first photoelectric sensor 611 and the second photoelectric sensor 621 are spaced apart along the first direction, thereby precisely controlling the range of motion of the first movable plate 52.
[0075] In addition, multiple weight-reducing holes are provided on the base plate 51, the first movable plate 52, and the second movable plate 53. Without affecting the overall structural strength and performance, the weight of the device is reduced, which is beneficial for the application and installation layout of the device under different working conditions.
