Description

Technical Field

[0001] This application relates to the field of tray handling technology, and in particular to handling grippers for welding trays. Background Technology

[0002] Currently, the handling of soldering trays refers to the operations of transferring, positioning, or feeding trays carrying components (such as SMT placement trays, PCB trays, etc.) during the electronic manufacturing process. This involves the coordinated operation of manual labor or automated equipment (such as AGVs, robotic arms, conveyor belts, etc.). Its core objective is to ensure the accurate and efficient transportation of components before, during, and after soldering.

[0003] A Chinese patent with publication number CN207046406U discloses an automatic tray handling device, comprising a first handling track, a first handling drive, a handling connecting base plate, a second handling track, a second handling drive, a handling suction cup fixing plate, and a handling suction cup. The first handling drive is slidably engaged with the first handling track; the handling connecting base plate is fixedly connected to the first handling drive; the second handling track and the second handling drive are fixedly connected to the handling connecting base plate; one side of the handling suction cup fixing plate is slidably engaged with the second handling track, and the other side is fixedly connected to the second handling drive; the handling suction cup is fixed to the handling suction cup fixing plate; and the handling suction cup adsorbs the tray.

[0004] In related technologies, the transfer suction cup is mounted on the transfer suction cup fixing plate. When in use, the transfer suction cup picks up the material tray, and then the transfer suction cup slides back and forth on the first track to realize the transfer of the material tray.

[0005] Regarding the aforementioned technologies, the inventors believe that if the suction cup fails during the movement of the material tray when it is lifted by the suction cup, the material tray is likely to fall off the suction cup, thus affecting the transportation of the material tray. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a handling gripper for welding trays, which solves the technical problem that if the suction cup fails during the movement of the tray when it is picked up by the suction cup, the tray will easily fall off the suction cup, thus affecting the transportation of the tray.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A transport gripper for welding trays includes: a frame for supporting the transport gripper; gripper bodies, two sets of gripper bodies being disposed opposite each other on the frame and slidably mounted on the frame; a drive assembly mounted on the frame for driving the gripper bodies to slide on the frame; and a positioning assembly mounted on the frame for positioning the tray.

[0009] Furthermore, a mounting block is provided on the frame, a guide rod is mounted on the mounting block, and a slider is slidably mounted on the frame. The slider slides in cooperation with the guide rod, and one end of the guide rod passes through the slider.

[0010] Furthermore, the drive assembly includes a drive cylinder mounted on the mounting block, and the piston rod of the drive cylinder is connected to the gripper body.

[0011] Furthermore, a support spring is provided between the mounting block and the slider, and the support spring abuts against a support surface between the mounting block and the slider, the support surface being horizontally positioned.

[0012] Furthermore, the gripper body is provided with a groove, which is connected to the support surface.

[0013] Furthermore, a positioning hole is provided on the side of the gripper body near the support surface. Several positioning holes are spaced apart on the gripper body. The positioning component includes a positioning pin, which is installed in the positioning hole and is used to position the pallet.

[0014] Furthermore, a guide slope is formed on the side of the gripper body near the groove, and the guide slope is inclined toward the inside of the groove.

[0015] In summary, this application includes at least the following beneficial technical effects for the handling grippers used in welding trays:

[0016] During use, the frame moves towards the side closer to the tray, and then the drive component drives the gripper body to slide on the frame, so that the gripper body can clamp the tray. Then the positioning component positions the tray, and then the tray moves with the frame, thereby preventing the suction cup from failing during the movement when the tray is picked up by the suction cup, preventing the tray from falling off the suction cup, and thus improving the transport efficiency of the tray.

[0017] By using guide rods, drive cylinders, and support springs on the mounting block, the stability of the gripper body moving on the frame is improved.

[0018] The locating holes and locating pins, as well as the pull grooves on the gripper body, prevent the material tray from falling off the gripper body. Attached Figure Description

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0025] This application discloses a handling gripper for welding trays.

[0026] Reference Fig. 1 A handling gripper for welding trays includes a frame 1, on which gripper bodies 2 are mounted, with two gripper bodies 2 spaced apart. A drive assembly 3 is mounted on the frame 1 to move the gripper bodies 2 and clamp the tray. A positioning assembly 4 is also mounted on the frame 1 to position the tray.

[0027] Reference Figs. 2-3 The frame 1 is provided with mounting blocks 11. The mounting blocks 11 have a rectangular cross-section, and two mounting blocks 11 are spaced apart along the width direction on the frame 1. Both mounting blocks 11 are mounted on the frame 1. Furthermore, the drive assembly 3 includes guide rods 31. Three guide rods 31 are spaced apart along the length direction of the mounting blocks 11. One end of each of the three guide rods 31 passes through two mounting blocks 11 in sequence, and both ends of the guide rods 31 passing through the mounting blocks 11 are connected to the frame 1.

[0028] Furthermore, a slider 32 is provided on the frame 1, with the slider 32 located on the opposite side of the two mounting blocks 11, and one end of each guide rod 31 passing through the corresponding slider 32. The gripper bodies 2 are arranged opposite each other, and both gripper bodies 2 are mounted on the sliders 32 on both sides. In use, the gripper bodies 2 move along the guide rod 31 on the frame 1 towards or away from each other.

[0029] To improve the ease of movement of the gripper body 2 on the frame 1, each of the two sliders 32 is equipped with a drive cylinder 33. The drive cylinders 33 are horizontally mounted on the mounting block 11, and one end of the piston rod of each drive cylinder 33 is connected to the gripper body 2. In use, the gripper body 2 moves towards or away from each other under the action of the drive cylinders 33. In addition, to improve the stability of the movement of the gripper body 2 on the frame 1, a support spring 34 is provided between the mounting block 11 and the sliders 32. The support spring 34 is sleeved on the guide rod 31, and both ends of the support spring 34 are respectively pressed against the mounting block 11 and the slider 32. When the gripper body 2 moves towards the side that is closer to each other, the support spring 34 is compressed, and the support spring 34 buffers the gripper body 2.

[0030] Furthermore, to improve the stability of the material tray after it is clamped by the gripper body 2, a support surface 21 is formed on the side of the gripper body 2 that is close to each other, and the support surfaces 21 on the two gripper bodies 2 are set horizontally. In use, the two ends of the material tray rest on the support surfaces 21 of the gripper body 2. In addition, a groove 22 is provided on the gripper body 2, which is connected to the support surface 21. In use, the two ends of the material tray body are engaged in the groove 22 of the gripper body 2. Thus, when the drive cylinder 33 drives the gripper body 2 to move, the material tray will not fall off the gripper body 2. Because the material tray body is engaged in the groove 22 of the gripper body 2, even if the drive cylinder 33 fails, the material tray will not fall directly off the gripper body 2.

[0031] In addition, a guide slope 23 is formed on the gripper body 2. The guide slope 23 is inclined towards the inner side near the groove 22. When in use, the guide slope 23 guides the material tray, thereby improving the convenience of the material tray being clamped on the gripper body 2.

[0032] To improve the stability of the material tray on the frame 1, a positioning hole 24 is provided on the side of the gripper body 2 near the support surface 21. Several positioning holes 24 are evenly spaced on the gripper body 2. The positioning component 4 includes a positioning pin 41, which is installed in the positioning hole 24 of the gripper body 2. One end of the positioning pin 41 is inserted into the positioning hole 24 of the gripper body 2. When the material tray swings on the gripper body 2, the positioning pin 41 engages with the material tray. Because several positioning holes 24 are spaced apart on the gripper body 2, the position of the positioning pin 41 on the gripper body 2 can be adjusted according to the size of the material tray, thereby improving the stability of the material tray on the gripper body 2.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
