[0003] Existing pitch control modules are typically large in size and weight. When using this type of pitch control module to adjust product spacing, it not only increases the inertia of the equipment, reducing its operating efficiency, but also increases its energy consumption. Furthermore, during operation, the pitch control module generates greater vibration and noise due to inertia, affecting the equipment's operating accuracy and lifespan, and also negatively impacting the working environment. Utility Model Content

[0009] A pitch-changing assembly includes a rotating tube and a pitch-changing solenoid. The two ends of the rotating tube are rotatably mounted on the mounting plate. The rotating tube is hollow and extends along the X direction. The pitch-changing solenoid is sleeved and connected to the rotating tube. The pitch-changing solenoid is provided with multiple sliding tracks. The multiple sliding tracks are symmetrically arranged about the central axis of the mounting plate. Each sliding track extends spirally along the axial direction of the pitch-changing solenoid, and the distance between any two adjacent sliding tracks gradually decreases along the axial direction of the pitch-changing solenoid.

[0010] A drive assembly is disposed on the mounting plate and is connected to the rotating tube body for driving the rotating tube body to rotate around its own axis.

[0011] The adsorption assembly is provided in multiple ways, and each adsorption assembly corresponds one-to-one with a sliding track. Each adsorption assembly includes a sliding seat and an adsorption element. The sliding seat is slidably engaged in the sliding track, and the adsorption element is disposed on the sliding seat. The adsorption element is configured to adsorb the product.

[0012] The variable pitch module also includes at least one positioning element, which is detachably connected to the mounting plate. The positioning element has a through hole through which both the variable pitch solenoid and the rotating tube can rotatably pass.

[0013] Optionally, the positioning element is disposed on the central axis of the mounting plate.

[0014] Optionally, the variable pitch module further includes a connector that passes through the mounting plate and is threaded onto the positioning member.

[0015] Optionally, the variable pitch module further includes a washer ring, through which the connector passes and is sandwiched between the connector and the mounting plate.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a variable-pitch module, including a handling device, a mounting plate, a variable-pitch assembly, a drive assembly, and an adsorption assembly. When transferring products between different processing steps and adjusting the product spacing, this variable-pitch module is used to handle the products. First, the handling device moves the mounting plate along the X, Y, and Z directions, positioning the adsorption assembly above the product. Then, the drive assembly drives the rotating tube to rotate around its own axis, thereby rotating the variable-pitch solenoid. During this process, the sliding seat slides along the sliding track, changing the spacing between adjacent adsorption components. This ensures that the spacing between the adsorption components of multiple adsorption assemblies is the same as the spacing between multiple products in the current process. Next, the handling device moves along the Z direction, allowing the adsorption components to contact the product and adsorb it. Then, the handling device again moves the mounting plate along the X, Y, and Z directions, transferring the product to the next process. During this process, the drive assembly can be controlled again to rotate the rotating tube, adjusting the spacing between the adsorption components of multiple adsorption assemblies, and thus the spacing between multiple products to meet the process requirements.

[0023] By setting multiple weight-reducing grooves on the mounting plate and simultaneously setting a rotating tube to drive the variable pitch screw to rotate, the overall weight of the structure can be reduced, the inertia of the equipment during operation can be reduced, the operating efficiency can be improved, noise pollution can be reduced, and the impact on the operating accuracy and service life of the equipment can be avoided.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] This embodiment provides a variable pitch module, such as Figures 1 to 3 As shown, this can reduce the overall weight of the structure, reduce the inertia of the equipment during operation, improve operating efficiency, reduce noise pollution, and avoid affecting the operating accuracy and service life of the equipment.

[0039] like Figures 1 to 3As shown, the pitch-changing module includes a handling device, a mounting plate 1, a pitch-changing assembly 2, a drive assembly 3, and an adsorption assembly 4. The handling device is movable along the X, Y, and Z directions, with each direction perpendicular to the others. The mounting plate 1 is mounted on the handling device and has multiple weight-reducing grooves 11. The handling device can drive the mounting plate 1 to move along the X, Y, and Z directions. The pitch-changing assembly 2 includes a rotating tube 21 and a pitch-changing solenoid 22. The two ends of the rotating tube 21 are rotatably mounted on the mounting plate 1. The rotating tube 21 is hollow and extends along the X direction. The pitch-changing solenoid 22 is sleeved and connected to the rotating tube 21. Multiple sliding tracks 221 are provided on the pitch-changing solenoid 22, symmetrically arranged about the central axis of the mounting plate 1. Each sliding track 221 extends spirally along the axial direction of the pitch-changing solenoid 22, and the distance between any two adjacent sliding tracks 221 gradually decreases along the axial direction of the pitch-changing solenoid 22. The drive assembly 3 is mounted on the mounting plate 1 and is connected to the rotating tube 21 for driving the rotating tube 21 to rotate around its own axis. Multiple adsorption assemblies 4 are provided, each corresponding to one of the multiple sliding tracks 221. Each adsorption assembly 4 includes a sliding seat 41 and an adsorption element 42. The sliding seat 41 is slidably engaged within the sliding track 221. The adsorption element 42 is mounted on the sliding seat 41 and is configured to adsorb the product.

[0040] When transferring products between different processing steps and adjusting the product spacing, this variable-pitch module is used for product handling. First, the handling equipment moves the mounting plate 1 along the X, Y, and Z directions, positioning the adsorption component 4 above the product. Then, the drive component 3 drives the rotating tube 21 to rotate around its own axis, thereby rotating the variable-pitch solenoid 22. During this process, the sliding seat 41 slides along the sliding track 221, changing the spacing between two adjacent adsorption components 42. This ensures that the spacing between the adsorption components 42 of multiple adsorption components 4 is the same as the spacing between multiple products in the current process. Then, the handling equipment moves along the Z direction, allowing the adsorption components 42 to contact the product and adsorb it. The handling equipment then moves the mounting plate 1 again along the X, Y, and Z directions, transferring the product to the next process. During this process, the drive component 3 can be controlled again to rotate the rotating tube 21, adjusting the spacing between the adsorption components 42 of multiple adsorption components 4, and thus adjusting the spacing between multiple products to meet the process requirements. By setting multiple weight-reducing grooves 11 on the mounting plate 1, and simultaneously setting a rotating tube 21 to drive the variable pitch screw to rotate, the rotating tube 21 has a hollow structure, which can reduce the overall weight of the structure, reduce the inertia of the equipment during operation, improve operating efficiency, reduce noise pollution, and avoid affecting the operating accuracy and service life of the equipment.

[0041] It should be noted that the variable pitch solenoid 22 is made of engineering plastic, which can further reduce the weight of the variable pitch module and reduce the load on the equipment.

[0042] Optionally, such as Figures 1 to 3 As shown, the variable pitch module also includes at least one positioning element 12. The positioning element 12 is detachably connected to the mounting plate 1, and the positioning element 12 has a through hole through which both the variable pitch solenoid 22 and the rotating tube 21 can rotatably pass. By setting the positioning element 12, on the one hand, it can provide vertical support for the variable pitch solenoid 22 and the rotating tube 21, reduce the downward deflection of the variable pitch solenoid 22 and the rotating tube 21, and improve the stability of the structure; on the other hand, it can constrain the variable pitch solenoid 22 and the rotating tube 21 radially, preventing radial runout or vibration caused by the rotation of the rotating tube 21 around its own axis.

[0043] In this embodiment, a positioning element 12 is provided, and the positioning element 12 is located on the central axis of the mounting plate 1, that is, the positioning element 12 is centrally located. By setting the positioning element 12 on the central axis of the mounting plate 1, the positioning element 12 can provide a uniformly distributed support force for the variable pitch solenoid 22 and the rotating tube 21, thereby reducing the bending deformation of both.

[0044] In other embodiments, other numbers of positioning elements 12 may be provided as needed. The positioning elements 12 may be located at the end of the mounting plate 1 or other positions, and are not limited here.

[0045] Optionally, the variable pitch module also includes a connector. When installing the positioning member 12, simply attach the positioning member 12 to the mounting plate 1 and keep the positioning member 12 on the central axis of the mounting plate 1. Then, pass the connector through the mounting plate 1 and screw it onto the positioning member 12. The structure is simple and the operation is convenient.

[0046] For example, the connector includes a bolt. In other embodiments, screws or the like may be used as connectors as needed, and this is not limited here.

[0047] Optionally, the variable pitch module also includes a washer. The connector passes through the washer, and the washer is sandwiched between the connector and the mounting plate 1. By providing the washer, the contact area between the connector and the mounting plate 1 can be increased, local pressure can be reduced, and stress concentration can be avoided to prevent damage to the mounting plate 1.

[0048] Optionally, such as Figures 1 to 3As shown, the variable pitch module also includes a slider 5 and a guide rail 6. The guide rail 6 is mounted on the mounting plate 1 and extends along the X direction. The slider 5 is mounted on the sliding seat 41, and the slider 5 slides in conjunction with the guide rail 6. When it is necessary to adjust the spacing between the adsorption components 42, the drive assembly 3 drives the rotating tube 21 to rotate around its own axis, which in turn drives the variable pitch screw to rotate, causing the sliding seat 41 to drive the adsorption components 42 to slide along the sliding rail 221, thereby changing the spacing between the adsorption components 42. During this process, the slider 5 moves along the guide rail 6. By setting the guide rail 6 and the slider 5 to slide in conjunction, on the one hand, it can provide guidance and limit for the movement of the sliding seat 41, so that the sliding seat 41 drives the adsorption components 42 to always move along the X direction, avoiding up and down swinging. On the other hand, it can also increase the vertical lifting force of the adsorption assembly 4, ensuring the overall stability of the structure.

[0049] In some embodiments, the mounting plate 1 has a sliding groove that extends along the X direction. The sliding seat 41 has a limiting protrusion that is slidably engaged within the sliding groove. By providing the sliding groove, the overall weight of the variable pitch module can be further reduced. Furthermore, the sliding engagement of the limiting protrusion and the sliding groove provides guidance and limiting for the movement of the sliding seat 41, ensuring its movement accuracy and preventing tilting or displacement. This ensures that the spacing between the adsorption components 42 matches the required spacing of the product.

[0050] Optionally, such as Figures 1 to 3 As shown, the drive assembly 3 includes a drive mechanism 31, a driving wheel 32, a driven wheel 33, and a transmission component 34. The housing of the drive mechanism 31 is mounted on the mounting plate 1, and the output end of the drive mechanism 31 is connected to the driving wheel 32 for driving the driving wheel 32 to rotate. The driven wheel 33 is mounted on the rotating tube 21, and the transmission component 34 is wound around the driving wheel 32 and the driven wheel 33. When it is necessary to adjust the spacing between the adsorption components 42, the drive mechanism 31 is activated, which drives the driving wheel 32 to rotate. This causes the driving wheel 32 to drive the driven wheel 33 to rotate via the transmission component 34. The driven wheel 33 is mounted on the rotating tube 21, which causes the variable pitch solenoid 22 to rotate around its own axis via the rotating tube 21. This causes the sliding seat 41 to move the adsorption components 42 along the sliding track 221, thereby adjusting the spacing between the adsorption components 42. The structure is simple and easy to operate.

[0051] For example, the drive mechanism 31 includes a rotary motor, and the conveyor 34 includes a conveyor belt.

[0052] Optionally, such as Figures 1 to 3As shown, the drive assembly 3 also includes a protective cover 35. The protective cover 35 is mounted on the mounting plate 1 and covers the drive wheel 32, driven wheel 33, and transmission component 34. By covering the drive wheel 32, driven wheel 33, and transmission component 34 with the protective cover 35, the drive wheel 32, driven wheel 33, and transmission component 34 can be protected from damage caused by impacts from external objects, and personnel can also be prevented from being injured by accidental contact.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
