Description

A backplate quick-grip jig Technical Field

[0001] This utility model relates to the field of jig technology, and in particular to a backplate quick-grip jig. Background Technology

[0002] Fixtures are mainly used as tools to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures, and circuit board testing fixtures. When processing backplanes, it is necessary to use gripping fixtures to grip and place the backplanes.

[0003] In the existing technology, during the backplate gripping process, some backplates are fragile and require custom protective sleeves to be fitted at the corners to cushion the impact during transportation and stacking. When gripping the backplates with a jig, the backplates are gripped directly, which is not convenient for the corresponding protective sleeves to be gripped simultaneously. The protective sleeves are scattered directly at the gripping point, which will affect the gripping of subsequent backplates. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that when a backplate is gripped by a jig, it is not convenient to grip the corresponding protective sleeve at the same time, which will affect the subsequent gripping of the backplate. Therefore, a backplate quick gripping jig is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a backplate quick-gripping fixture, comprising a fixed plate, a first gripping mechanism fixedly connected to one side of the fixed plate, the first gripping mechanism comprising a first linear module, one side of the first linear module fixedly connected to one end of the fixed plate, a first connecting plate slidably connected to both ends of the other side of the first linear module, a second linear module fixedly connected to one side of the first connecting plate, a first pneumatic gripper fixedly connected to both ends of one side of the second linear module, a second gripping mechanism installed in the middle of the other side of the first linear module, the second gripping mechanism comprising a second connecting plate, a second guide assembly installed at both ends of one side of the second connecting plate, a drive assembly slidably connected to one side of the second guide assembly, a steering plate installed at the output end of the drive assembly, and an adsorption assembly installed at both ends of one side of the steering plate.

[0006] Preferably, a second pneumatic gripper is fixedly connected to the middle of one side of the second linear module, and the second pneumatic gripper is disposed between two first pneumatic grippers. A first guide assembly is slidably connected to the other side of the second linear module, and one side of the first guide assembly is fixedly connected to one side of the fixed plate.

[0007] Preferably, cylinders are fixedly connected to both ends of one side of the second connecting plate, and one end of the cylinder is fixedly connected to one side of the drive assembly.

[0008] Preferably, a positioning rod is installed on the side of the steering plate.

[0009] Preferably, a connector is fixedly connected to the other end of the fixed plate, and one end of the connector is connected to the robotic arm.

[0010] Preferably, the positioning mechanism includes a mounting plate, one side of which is fixedly connected to the other side of the steering plate, a positioning block is rotatably connected to one side of the mounting plate, an auxiliary plate is fixedly connected to one end of the positioning block, and a steering rod is installed at one end of the auxiliary plate.

[0011] Preferably, a push plate is fixedly connected to the other end of the positioning block, an electric push rod is rotatably connected to one end of the push plate, a first connecting rod is rotatably connected to one end of the electric push rod, and one end of the first connecting rod is fixedly connected to one side of the mounting plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the second linear module drives the two first pneumatic grippers above it to move, so that the four first pneumatic grippers move to the protective sleeve at the corner of the back plate to clamp and fix the protective sleeve. The first linear module drives the two sets of second linear modules to move, moving the protective sleeve to separate from the back plate. The adsorption component can adsorb and fix the back plate. The robotic arm drives the fixed back plate to transfer it, realizing the stable gripping of the back plate and the protective sleeve, avoiding the protective sleeve from falling off and scattering, which would cause production obstacles.

[0014] 2. In this utility model, after the adsorption component works to adsorb and grasp the back plate, the electric push rod works to drive the push plate to move, and the auxiliary plate to make arc movement, so that the four sets of steering rods clamp and position the four corners of the back plate respectively, thereby improving the gripping effect of the back plate and preventing the adsorption component from having insufficient gripping force, which would cause the back plate to fall and be damaged.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As shown in Figures 1-4, this utility model provides a quick-grip fixture for backplates, including a fixed plate 1. A first gripping mechanism 3 is fixedly connected to one side of the fixed plate 1. The first gripping mechanism 3 includes a first linear module 31, one side of which is fixedly connected to one end of the fixed plate 1. Both ends of the other side of the first linear module 31 are slidably connected to a first connecting plate 36. A second linear module 33 is fixedly connected to one side of the first connecting plate 36. Both ends of one side of the second linear module 33 are fixedly connected to a first pneumatic gripper 34. A second gripping mechanism 4 is installed in the middle of the other side of the first linear module 31. The second gripping mechanism 4 includes a second connecting plate 41, both ends of which are... A second guide assembly 42 is installed, and a drive assembly 44 is slidably connected to one side of the second guide assembly 42. A steering plate 47 is installed at the output end of the drive assembly 44, and adsorption assemblies 45 are installed at both ends of one side of the steering plate 47. A second pneumatic gripper 35 is fixedly connected to the middle of one side of the second linear module 33. The second pneumatic gripper 35 is located between two first pneumatic grippers 34. A first guide assembly 32 is slidably connected to the other side of the second linear module 33. One side of the first guide assembly 32 is fixedly connected to one side of the fixed plate 1.

A positioning rod 46 is installed on the side of the steering plate 47.

[0023] Both the first linear module 31 and the second linear module 33 include a working motor, a housing, a threaded rod, and two movable sleeves. The threads on both sides of the middle of the threaded rod are set in opposite directions. When the working motor drives the threaded rod to rotate, the threaded movable sleeves move, adjusting the distance between the two movable sleeves. Changing the distance between the movable sleeves can drive the connected components to move respectively. The robotic arm drives the fixture to move to the back plate stacking position. There are protective sleeves at the four corners of the back plate corresponding to the stacking. First, the second linear module 33 drives the two first pneumatic grippers 34 above it to move, adjusting the distance between the two first pneumatic grippers 34 in the same group, so that the four first pneumatic grippers... The claws 34 move to the protective sleeves at the corners of the back plate. The first pneumatic gripper 34 can clamp and fix the protective sleeves. The first linear module 31 drives the two sets of second linear modules 33 to move. The second linear modules 33 slide on the first guide component 32, making the movement of the second linear modules 33 more stable.

Adjust the height of the adsorption component 45 to make it fit against the upper side of the back plate. The adsorption component 45 can adsorb and fix the back plate. The robotic arm drives the fixed back plate to transfer the protective sleeves, realizing the stable gripping of the back plate and the protective sleeves, and avoiding the protective sleeves from falling off and scattering, which would cause production obstacles.

[0025] After the adsorption assembly 45 adsorbs and grips the back panel, the electric push rod 53 drives one end of the push plate 54 to move. The two ends of the electric push rod 53 rotate on the first connecting rod 52 and the push plate 54 respectively, driving the positioning block 57 to rotate. The auxiliary plate 56 makes an arc movement, driving the position of the steering rod 55 to change, so that the four sets of steering rods 55 clamp and position the four corners of the back panel respectively, thereby improving the gripping effect of the back panel and preventing the adsorption assembly 45 from having insufficient gripping force, which would cause the back panel to fall and be damaged. After the robotic arm is connected to the top of the connector 2, the entire fixture can be moved by driving the robotic arm to transfer the gripped back panel.

[0026] The usage and working principle of this device are as follows: First, the second linear module 33 drives the two first pneumatic grippers 34 above it to move, so that the four first pneumatic grippers 34 move to the protective sleeves at the corners of the back plate. The first pneumatic grippers 34 can clamp and fix the protective sleeves. The first linear module 31 drives the two sets of second linear modules 33 to move, moving the protective sleeves to separate from the back plate. The height of the adsorption component 45 is adjusted so that it fits against the upper side of the back plate. The adsorption component 45 can adsorb and fix the back plate. The electric push rod 53 drives the push plate 54 to move, the positioning block 57 rotates, and the auxiliary plate 56 moves in an arc, which drives the position of the steering rod 55 to change, so that the four sets of steering rods 55 clamp and position the four corners of the back plate respectively.
