Figure 1 As shown, existing electroplating equipment features a conveyor belt 1' on either side of a plate 900', with each conveyor belt 1' used to transport and return the clamps 800'. However, as the conveyor belt 1' lengthens, a tensioning mechanism is required to maintain tension. Prolonged transportation in a tensioned state shortens the service life of the conveyor belt 1', impacting production schedules.

[0010] As a preferred solution of the gripper transmission system, the first transfer mechanism and the second transfer mechanism both include a driving member, and the output end of the driving member is connected to the rotating shaft to drive the rotating shaft to rotate.

[0011] As a preferred solution of the gripper transmission system, it also includes a positioning mechanism, which includes multiple positioning sensors. The multiple positioning sensors are arranged one-to-one on the multiple manipulators, and the starting and end of the conveying line and the starting and end of the return line are all provided with positioning marks.

[0012] As a preferred solution of the gripper transmission system, the conveyor line is provided with a plurality of the slide rails, and the plurality of the slide rails are sequentially connected to form a straight line;

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a gripper transmission system, comprising two sets of transport units, each set of transport units comprising a conveyor line, a first transfer mechanism, a return line, and a second transfer mechanism that are sequentially connected to form a loop, the conveyor line and the return line each comprising at least one slide rail, a plurality of sliders that can slideably engage with the slide rails of the conveyor line and the return line, and a plurality of grippers that are connected one-to-one to the plurality of sliders.

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only show portions relevant to the present invention, not all of them.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention.

[0031] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0032] like Figure 2 As shown, the gripper transmission system of this embodiment includes two sets of transport units 1, each set of transport units 1 includes a conveyor line 11, a first transfer mechanism 12, a return line 13 and a second transfer mechanism 14 that are sequentially connected to form a loop, the conveyor line 11 and the return line 13 each include at least one slide rail 111, a plurality of sliders can be slidably fitted on the slide rail 111 of the conveyor line 11 and the slide rail 111 of the return line 13, and a plurality of grippers 800 are connected to the plurality of sliders in a one-to-one correspondence. The first transfer mechanism 12 is used to transfer the slider transported to the end of the conveyor line 11 to the beginning of the return line 13, and the second transfer mechanism 14 is used to transfer the slider transported to the end of the return line 13 to the beginning of the conveyor line 11.

[0033] By setting up a conveyor line 11, a first transfer mechanism 12, a return line 13 and a second transfer mechanism 14 that are connected in sequence to form a loop and are independent, not only can the gripping and transportation of the transported item 900 by the gripper 800 and the return of the gripper 800 be guaranteed, but also compared with the traditional gripper transmission system that uses a conveyor belt 1', the gripper transmission system divides the circulation system into four independently controlled modules, and uses a slide rail 111 to bear the weight of the slider and the gripper, which can avoid the situation where the conveyor belt is too long and needs to be tightened, thereby having a longer service life and being able to ensure the normal production progress of the equipment.

[0034] Preferably, the conveyor lines 11 of the two transport units 1 are arranged in parallel, and the two transport units 1 are respectively arranged on either side of the transport direction of the transported items 900 to ensure stable transportation of the transported items 900. Preferably, the conveyor line 11 and return line 13 of each transport unit 1 are parallel, and the rotation radius of the first transfer mechanism 12 and the second transfer mechanism 14 are also consistent. The specific structures of the first transfer mechanism 12 and the second transfer mechanism 14 will be described below.

[0035] Preferably, the first transfer mechanism 12 and the second transfer mechanism 14 both include multiple manipulators (not shown in the figure), which are used to clamp, move and lower the slider, that is, the manipulator of the first transfer mechanism 12 is used to clamp the slider from the end of the conveyor line 11 and lower the slider at the beginning of the return line 13, and the manipulator of the second transfer mechanism 14 is used to clamp the slider from the end of the return line 13 and lower the slider at the beginning of the conveyor line 11.

[0036] Preferably, the first transfer mechanism 12 and the second transfer mechanism 14 each include a rotating shaft 121 and a plurality of rotating rods 122 disposed on the rotating shaft 121. The rotating shaft 121 is capable of rotating along its own axis. The plurality of rotating rods 122 are spaced apart along the circumference of the rotating shaft 121, and the plurality of manipulators are disposed in a one-to-one correspondence with the plurality of rotating rods 122. Preferably, one end of the rotating rod 122 is connected to the rotating shaft 121, and the other end is connected to the manipulator. Rotation of the rotating shaft 121 drives the manipulator located at the other end of the rotating rod 122 to move, thereby enabling the manipulator to move between the conveyor line 11 and the return line 13.

[0037] Preferably, the first transfer mechanism 12 and the second transfer mechanism 14 both include a driving member (not shown in the figure), the output end of the driving member is connected to the rotating shaft 121 to drive the rotating shaft 121 to rotate. Optionally, the driving member is a motor.

[0038] In order to facilitate the control of the gripping and releasing actions of the manipulator, preferably, the gripper transmission system also includes a positioning mechanism, which includes a plurality of positioning sensors (not shown in the figure), and the plurality of positioning sensors are respectively arranged on a plurality of manipulators in a one-to-one correspondence, and the starting and end of the conveyor line 11 and the starting and end of the return line 13 are all provided with positioning marks. When the positioning sensor on the manipulator of the first transfer mechanism 12 senses the positioning mark at the end of the conveyor line 11, it performs a gripping action to grip the slider, and when it senses the positioning mark at the beginning of the return line 13, it performs a releasing action to put down the slider. When the positioning sensor on the manipulator of the second transfer mechanism 14 senses the positioning mark at the end of the return line 13, it performs a gripping action to grip the slider, and when it senses the positioning mark at the beginning of the conveyor line 11, it performs a releasing action to put down the slider.

[0039] To accommodate the long lengths of the conveyor line 11 and return line 13, in this embodiment, the conveyor line 11 is preferably provided with multiple slide rails 111, which are sequentially connected to form a straight line. The return line 13 is preferably provided with multiple slide rails 111, which are sequentially connected to form a straight line. Of course, in other embodiments, curved slide rails 111 may also be provided to meet the specific requirements of the transmission system.

[0040] In order to provide power to the sliders on the conveyor line 11 and the return line 13, preferably, the conveyor line 11 and the return line 13 each include at least one conveyor belt (not shown in the figure), which is used to drive the slider to move within the slide rail 111. The number of conveyor belts can be configured according to the needs of the actual conveyor system.

[0041] Preferably, in order to facilitate the conveyor belt to drive the movement of the slider, each conveyor belt is provided with multiple transmission rods (not shown in the figure), and the multiple transmission rods are evenly spaced in the length direction of the conveyor belt. One end of the multiple transmission rods is connected to the conveyor belt, and the other end can abut against the side of the slider to push the slider to move in the slide rail 111. It can be seen that the extension direction of the conveyor belt is parallel to the extension direction of the slide rail 111.

[0042] In order to ensure the rapid return of the grippers 800 and prevent the problem of insufficient grippers 800 on the conveyor line 11, preferably, in this embodiment, the return line 13 is provided with at least two conveyor belts, which are connected in sequence, and the conveying speed of at least two conveyor belts gradually decreases along the conveying direction of the return line 13. That is, on the return line 13, the upstream conveyor belt has a higher conveying speed, which can quickly transport the sliders transferred from the first transfer mechanism 12 downstream, so that a large number of grippers 800 are gathered on the downstream conveyor belt, ensuring that the conveyor line 11 has a sufficient supply of grippers 800. In this embodiment, the return line 13 is provided with three conveyor belts, namely the first conveyor belt, the second conveyor belt, and the third conveyor belt along the conveying direction of the return line 13.

[0043] To accommodate the long overall length of conveyor line 11, preferably, conveyor line 11 is provided with multiple conveyor belts, which are sequentially connected and have a consistent transport speed to ensure a balanced movement speed of the slider and gripper 800, thereby ensuring uniform transport of the transported items 900. Furthermore, the transport speed of the conveyor belt of conveyor line 11 is lower than the maximum transport speed of the at least two conveyor belts of return line 13, further ensuring a sufficient supply of grippers 800 for conveyor line 11.

[0044] Preferably, baffles (not shown in the figure) are provided at the ends of the conveying line 11 and the return line 13 to prevent the transfer mechanism from transferring in an untimely manner and causing the slider to drive the clamp 800 to fall along the transportation direction.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
