[0002] Currently, automated equipment is increasingly used in the automated processing of various products. This equipment typically includes automatic conveying devices to transport products to preset processing positions. Common conveying devices include roller conveyor systems and belt conveyor systems. In existing technologies, the conveying channels of these systems usually have fixed dimensions, or can only be finely adjusted in the width direction, and the adjustment operation requires manual intervention, which is cumbersome. Therefore, under normal circumstances, specific processing equipment can only process products within a specific width range. When the width of the product varies significantly, it is necessary to change the conveying system and processing equipment, leading to low equipment utilization and increased equipment costs.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof.

[0018] See Figures 1 to 6 The adjustable-width track conveying device shown is specifically divided into a support base 4, a first conveying module 1, and a second conveying module 2, wherein: The support base 4 is fixedly installed to serve as the mounting base for the track transmission device 100; The first transmission module 1 specifically includes a first transmission base 11 and a first transmission component 12 disposed on one side of the first transmission base 11. The first transmission component 12 is rotatably disposed in a first direction, wherein the first transmission base 11 is fixedly disposed on the support base 4. The second transmission module 2 includes a second transmission base 21 and a second transmission component 22 disposed on one side of the second transmission base 21. The second transmission component 22 is also rotatably disposed in the first direction. The first transmission base 11 and the second transmission base 21 are spaced apart from each other in the second direction, forming a transmission channel for transmitting the item to be transmitted. The second direction is perpendicular to the first direction. Specifically, the first direction and the second direction are two different directions that are perpendicular to each other and both extend horizontally. The first transmission component 12 and the second transmission component 22 are both disposed in the transmission channel, and they cooperate with each other to form a transmission structure that supports and transmits the item to be transmitted. Specifically, both the first transmission component 12 and the second transmission component 22 are belt transmission components, that is, the transmission belt is tensioned between multiple transmission wheels, and the transmission belt can be rotated by driving one of the transmission wheels. The two ends of the item to be transmitted along the second direction are respectively supported on the transmission belts of the first transmission component 12 and the second transmission component 22. The upper surfaces of the first transmission component 12 and the second transmission component 22 constitute the transmission support surface of the transmission structure. When the two sets of transmission belts rotate synchronously, the item to be transmitted is conveyed along the first direction. In this embodiment, both the first transmission component 12 and the second transmission component 22 include three sets of transmission belt assemblies arranged sequentially and at intervals along the first direction. The three sets of transmission belt assemblies cooperate with each other to form the transmission of the item to be transmitted along the first direction.

[0019] In the track transmission device 100, the second transmission seat 21 can be slidably mounted on the support seat 4 in the second direction, which allows the width of the transmission channel to be adjusted. Correspondingly, the distance between the first transmission component 12 and the second transmission component 22 is also adjusted to provide a component of the corresponding width for support and transmission.

[0020] The track transmission device 100 also includes an adjustment mechanism 3 for driving the first transmission seat 11 and the second transmission seat 21 to move relative to each other along a second direction, thereby adjusting the width of the track transmission device 100. The adjustment mechanism 3 includes two sets of screw-nut assemblies spaced apart along a first direction. Each set of screw-nut assemblies includes a screw 31 extending along a second direction and a nut 32 threadedly connected to the screw 31. The screw 31 is rotatably mounted on a support seat 4 about its own axis, and the nut 32 is fixed to the second transmission seat 21. The adjustment mechanism 3 also includes a drive assembly for driving the two sets of screws 31 to rotate synchronously about their own axes. Thus, under the action of the drive assembly, the two sets of screws 31 rotate synchronously and cooperate with the corresponding nuts 32, causing the two sets of nuts 32 to move the second transmission seat 21 along the length direction of the screw 31, thereby changing the distance between the first transmission seat 11 and the second transmission seat 21, and thus adjusting the width of the transmission channel.

[0021] In other words, in the track transmission device 100 of this embodiment, by setting a first transmission module 1 and a second transmission module 2 that are set separately from each other, the second transmission seat 21 can be moved as a whole relative to the first transmission seat 11, thereby adjusting the distance between the two, and thus changing the distance between the first transmission component 12 and the second transmission component 22. This enables the transmission of parts of different sizes to meet the transmission and processing requirements of different models of products. By cooperating with the above-mentioned drive component and two sets of screw and nut components, the second transmission seat 21 can be moved stably as a whole relative to the first transmission seat 11 in the second direction. The two ends of the second transmission seat 21 move in unison, enabling precise width adjustment. At the same time, the above-mentioned adjustment action can be achieved by a single drive component, which is simple in structure and convenient in adjustment.

[0022] Specifically, the drive assembly includes a synchronous belt assembly, which comprises two synchronous pulleys 35 spaced apart along a first direction on the first transmission seat 11 or on the support seat 4, a first synchronous belt 34 tensioned between the two synchronous pulleys 35, and a drive motor 33 that drives the first synchronous belt 34 to rotate in the first direction. The two synchronous pulleys 35 are arranged in a one-to-one correspondence with the two lead screws 31, and the two synchronous pulleys 35 are fixedly connected to or driven by the two lead screws 31 respectively. Thus, the synchronous rotation of the two lead screws 31 is achieved by the aforementioned set of drive motors 33, thereby causing the two ends of the second transmission seat 21 to move synchronously relative to the first transmission seat 11.

[0023] In this embodiment, the aforementioned synchronous belt assembly and the first transmission assembly 12 are respectively disposed on opposite sides of the first transmission base 11 in the second direction. That is, the synchronous belt assembly is disposed on the outside of the transmission channel to avoid occupying space within the transmission channel and to avoid possible interference with the first transmission assembly 12 and the item to be transmitted during transmission. The two synchronous pulleys 35 are connected to the two lead screws 31 by transmission assemblies, and the transmission ratios of the two sets of transmission assemblies are the same to ensure that the distance the nuts 32 in the two sets of lead screw nut assemblies move along the lead screw 31 is always synchronized. Specifically, the transmission assembly includes a first wheel 38 coaxially fixed to the end of the lead screw 31, a second wheel 36 coaxially and fixed to the synchronous pulley 35, and a second synchronous belt 37 tensioned between the first wheel 38 and the second wheel 36. Here, the rotating shaft of the synchronous pulley 35 is rotatably mounted on the first transmission seat 11 in a second direction, with its two ends protruding from opposite sides of the first transmission seat 11. The second wheel 36 and the synchronous pulley 35 are respectively mounted on the two ends of the rotating shaft. The first wheel 38, the second wheel 36 and the second synchronous belt 37 cooperate with each other and are located in the transmission channel.

[0024] Referring to the accompanying drawings, in this embodiment, the support base 4 includes two support bodies 41 spaced apart along a first direction. Each of the two support bodies 41 extends along a second direction. The two ends of the first transmission base 11 are fixedly connected to the two support bodies 41. Each support body 41 is provided with a guide rail 42, which is parallel to the extending direction of the lead screw 31. The two ends of the second transmission base 21 are supported on the two support bodies 41 and slidably engaged with the two guide rails 42, thereby enabling the second transmission base 21 to move smoothly relative to the first transmission base 11 along the second direction. Here, a sliding portion 23 is fixedly provided on each of the two ends of the second transmission base 21. The sliding portion 23 is slidably connected to the guide rail 42, and a nut 32 is also fixedly mounted on the sliding portion 23 and engages with the lead screw 31, which is located above the guide rail 42.

[0025] Referring to the accompanying drawings, the track transmission device 100 also includes a moving device 5 for delivering the item to be transmitted along a first direction. The moving device 5 includes two sets of clamping assemblies, each set of clamping assemblies having a clamping part. The two sets of clamping assemblies are respectively slidably disposed on the first transmission seat 11 and the second transmission seat 21 along the first direction, and the clamping parts of the two sets of clamping assemblies are located in the transmission channel. Each clamping assembly has an adjustable clamping portion, allowing it to switch between a relaxed state and a clamping state. In the relaxed state, the component to be transferred is detached from the clamping portion and supported on the transmission support surface of the transmission structure. That is, the component is supported on the first transmission assembly 12 and the second transmission assembly 22 and is transmitted along the first direction when both rotate in the first direction. In the clamping state, the component to be transferred is detached from the transmission support surface, and is fixed to both sets of clamping assemblies and can move synchronously along the first direction. This allows the component to be detached from the first transmission assembly 12 and the second transmission assembly 22 and clamped by the clamping assembly, facilitating cooperation with the processing device 200 for processing. This helps ensure the accuracy of the positioning of the processing position 200 during processing and improves processing precision.

[0026] Specifically, each clamping assembly includes a clamping seat 51 and a lifting seat 52. The clamping seat 51 is slidably disposed on the first transmission seat 11 or the second transmission seat 21, and the clamping seat 51 has a limiting platform 511 extending into the transmission channel. The lifting seat 52 is located below the limiting platform 511 and is vertically movable. The limiting platform 511 and the lifting seat 52 cooperate with each other to form a clamping part. The clamping assembly also includes a lifting drive member 54 for driving the lifting seat 52 to move vertically. Specifically, a cylinder is used here. By driving the lifting seat 52 to move vertically, the clamping assembly can be switched between a relaxed state and a clamping state. Here, when the clamping assembly is in the relaxed state, the top surface of the lifting seat 52 is lower than the transmission support surface in the vertical direction; when the clamping assembly is in the clamping state, the top surface of the lifting seat 52 is higher than the transmission support surface in the vertical direction, so that the part to be transferred is transferred from the transmission support surface to the lifting seat 52. In a specific configuration, the lifting seat 52 is also provided with a positioning structure that corresponds to and cooperates with the component to be transferred, so that the component to be transferred is supported on the lifting seat 52 in a specific manner or posture, so as to facilitate the precise positioning of the component to be transferred.

[0027] Referring to the accompanying drawings, the moving device 5 also includes a slide base 53 supported on the bottom of the two sets of clamping components. One set of clamping components is fixed on the slide base 53, and the other set of clamping components is slidably disposed on the slide base 53 in a second direction. A sliding guide structure is provided between the slide base 53 and the clamping seat 51 of the set of clamping components to cooperate with each other. In this way, when the first transmission module 1 and the second transmission module 2 move relative to each other in the second direction, one set of clamping components slides relative to the slide base 53 in the second direction along with the second transmission module 2, so that the width between the two sets of clamping components is adjusted accordingly.

[0028] The track conveying device 100 includes multiple sets of moving devices 5, specifically two sets, all of which are spaced apart along a first direction. The track conveying device 100 also includes a base 6 providing sliding guidance for all moving devices 5 along the first direction. During transmission, the workpiece to be transferred can be moved between the conveying structure and the multiple sets of moving devices 5 to meet different conveying and processing requirements. Specifically, each set of moving devices 5 is configured to move between two adjacent sets of conveyor belt assemblies. Through the coordination of the movement of the moving device 5 along the first direction and the movement of the conveyor belt assemblies, processing of the workpiece to be transferred during its movement in the first direction, as well as its transmission in the first direction, are achieved.

[0029] See Figure 7 , Figure 8 As shown, the track transmission device 100 and the processing device 200 for bonding processing cooperate to process, wherein the part to be transferred is a carrier, and the carrier carries multiple products to be bonded; the processing device 200 includes a processing head 201 that moves along a second direction and a vision module 202. The processing head 201 picks up the part to be bonded from the material rack and performs bonding processing at the bonding position of the product on the carrier; the vision module 202 is used to take pictures and obtain the position of the product on the carrier and the bonding position to achieve precise bonding processing.

[0030] like Figure 9 As shown, the processing device 200 can be configured as two sets spaced apart along the first direction. The two sets of processing devices 200 cooperate with two sets of moving devices 5 respectively to achieve synchronous processing at two workstations and improve processing efficiency. In some application scenarios, such as when the size of the carrier is large, the first set of processing devices 200 can cooperate with the first set of moving devices 5 to complete the bonding processing of part of the product on the carrier. Then, the carrier is transferred to the second set of moving devices 5 so that it cooperates with the second set of processing devices 200 to complete the bonding processing of part of the product on the carrier. In this way, the corresponding processing equipment can meet the transfer and processing of products of different sizes, improve the utilization rate of the equipment, and reduce the equipment cost.
