Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning tray technology, specifically to a small workpiece positioning tray with vacuum adsorption function. Background Technology

[0002] A workpiece is a component of a product during the manufacturing process. It is also called a part, component, workpiece, hardware part, etc. A workpiece refers to the object being processed in the machining process; it can be a single part or an assembly of several parts fixed together. There are various processing methods for workpieces, including turning, milling, planing, grinding, casting, forging, etc. The processing steps for a workpiece also vary depending on the processing method. A positioning tray is needed to fix the workpiece in place during positioning.

[0003] Currently, a Chinese patent has disclosed a pallet device (authorization announcement number CN218752046U). The pallet device includes a pallet body, a supporting component, and a first and second limiting member arranged opposite to each other and spaced apart. The first limiting member has a first limiting end face, and the second limiting member has a second limiting end face, allowing the target workpiece to contact the first and second limiting end faces respectively, thereby placing the target workpiece in a predetermined position. This structural design facilitates manual placement of the mask template and allows for precise positioning of the pallet's physical center, reducing the accuracy requirements for the robotic arm's transmission. It also avoids positional deviations caused by misalignment during manual mask template placement, thus ensuring repeatability and accuracy during transmission.

[0004] According to the above references, the device, by setting a first and a second limiting member that are opposite to each other and spaced apart on the pallet body, facilitates the placement of the mask template manually or by a robotic arm. At the same time, it can accurately locate the physical center of the pallet, reduce the transmission accuracy requirements of the robotic arm, and ensure repeatability accuracy during transmission. However, when placing workpieces, the device does not have an ideal fixing effect. Workpieces are prone to displacement and falling when moving or being collided with, making it inconvenient to quickly fix the workpieces and reducing the effectiveness of the device.

[0005] Based on this, this utility model designs a small workpiece positioning tray with vacuum adsorption function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a small workpiece positioning tray with vacuum adsorption function.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A small workpiece positioning tray with vacuum adsorption function includes a placement plate, an mounting block on one side of the placement plate, and a fixing mechanism disposed on the inner wall of the placement plate. A plurality of evenly arranged first suction cups are installed on the inner wall of the placement plate, and the bottom end of the first suction cups is connected to a first conduit. A vacuum pump is installed on the inner wall of the mounting block, and one end of the first conduit passes through the placement plate and is connected to the suction pipe of the vacuum pump.

[0009] Furthermore, the fixing mechanism also includes a telescopic sleeve fixedly connected to the top of the first suction cup, the top of the telescopic sleeve extending through to the outer wall of the placement plate.

[0010] Furthermore, a filter screen is fixedly connected to the inner wall of the telescopic sleeve.

[0011] Furthermore, anti-slip blocks are fixedly connected to the four corners of the bottom of the placement plate.

[0012] Furthermore, a calibration plate is fixedly connected to the rear end of the top of the placement plate.

[0013] Furthermore, the inner wall of the calibration plate is equipped with several evenly distributed second suction cups, one end of which is aligned with the front end of the calibration plate.

[0014] Furthermore, the other end of the second suction cup is connected to a second conduit, one end of which passes through the calibration plate and the placement plate in sequence and is connected to the first conduit.

[0015] Furthermore, the top of the placement plate is provided with several evenly arranged mounting grooves, and the inner wall of the mounting grooves is provided with internal threads.

[0016] Furthermore, several of the aforementioned mounting slots are respectively disposed on both sides of the first suction cup.

[0017] Furthermore, the top of the placement plate is provided with two limiting blocks, and the mounting groove is threadedly connected to the limiting blocks via internal threads.

[0018] Beneficial effects

[0019] 1. When fixing the workpiece, the first suction cup at the top of the inner wall of the placement plate, in conjunction with the vacuum pump through the first conduit, generates suction to create a vacuum state inside the first suction cup, which can adsorb the workpiece on the placement plate. The telescopic sleeve on the first suction cup is made of flexible material, which can fit against the surface of the workpiece, improving the adsorption and fixing effect of the first suction cup on the workpiece. The workpiece can be squeezed onto the placement plate and fit against it. The filter screen inside the telescopic sleeve can prevent dust from adsorbing into the first suction cup. The anti-slip block at the bottom of the placement plate can support the placement plate and prevent it from shifting during use, which can quickly and stably fix the workpiece and adsorb and fix it.

[0020] 2. The calibration plate on the placement plate can calibrate the workpiece and keep it level. The second suction cup inside the calibration plate is connected to the first guide tube through the second guide tube, which can generate suction to fix the workpiece in contact with the calibration plate. The mounting groove on the placement plate is installed on the placement plate through internal thread and fits with the limiting block, which can limit and fix the workpiece. In conjunction with the suction cup, it can improve the stability of the workpiece, and can stably install and fix the workpiece, thereby improving the processing effect of the workpiece.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A small workpiece positioning tray with vacuum adsorption function includes a placement plate 1, an mounting block 2 on one side of the placement plate 1, and a fixing mechanism 3. The fixing mechanism 3 is disposed on the inner wall of the placement plate 1. A plurality of evenly arranged first suction cups 301 are installed on the inner wall of the placement plate 1. The bottom end of the first suction cups 301 is connected to a first conduit 302. A vacuum pump 303 is installed on the inner wall of the mounting block 2. One end of the first conduit 302 passes through the placement plate 1 and is connected to the suction pipe of the vacuum pump 303.

[0031] When fixing the workpiece on the placement plate 1, the vacuum pump 303 in the mounting block 2 is manually started. The vacuum pump 303 operates by absorbing air from the first suction cup 301 through the top suction pipe and cooperating with the first conduit 302. The air is discharged through the exhaust pipe, creating a vacuum state in the first suction cup 301. The pressure generated by the vacuum pump and the external pressure can adsorb and fix the workpiece, allowing for rapid fixation of the workpiece.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the fixing mechanism 3 further includes a telescopic sleeve 304 fixedly connected to the top of the first suction cup 301, the top of the telescopic sleeve 304 extending through to the outer wall of the placement plate 1.

[0033] When fixing the workpiece, the workpiece is placed on the placement plate 1, and the workpiece squeezes the telescopic sleeve 304 into the placement plate 1. The telescopic sleeve 304 is in contact with the surface of the workpiece, and the workpiece can be adsorbed and fixed by the first suction cup 301.

[0034] In this embodiment of the utility model, a filter screen 305 is fixedly connected to the inner wall of the telescopic sleeve 304.

[0035] When the telescopic sleeve 304 comes into contact with the workpiece, the filter screen 305 inside the telescopic sleeve 304 can prevent external dust from affecting the use of the vacuum pump 303 and improve the adsorption effect of the device on the workpiece.

[0036] In this embodiment of the utility model, anti-slip blocks 306 are fixedly connected to the four corners of the bottom of the placement plate 1.

[0037] The anti-slip block 306 at the bottom of the placement plate 1 can support the placement plate 1, increase the friction coefficient of the placement plate 1, and improve the stability of the placement plate 1.

[0038] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, a calibration plate 307 is fixedly connected to the rear end of the top of the placement plate 1.

[0041] When the workpiece is attached to the calibration plate 307, the second suction cup 308 inside the calibration plate 307 can adsorb and fix the workpiece, thus quickly fixing the workpiece.

[0042] In this embodiment of the utility model, the other end of the second suction cup 308 is connected to the second conduit 309, and one end of the second conduit 309 passes through the calibration plate 307 and the placement plate 1 in sequence and is connected to the first conduit 302.

[0043] When the second suction cup 308 adsorbs the workpiece, the second suction cup 308 can adsorb the air inside the second suction cup 308 by cooperating with the first conduit 302 through the second conduit 309 at one end, so that a vacuum state is formed inside the second suction cup 308. The pressure generated by the second suction cup 308 and the external pressure can adsorb and fix the workpiece.

[0044] In this embodiment of the utility model, the top of the placement plate 1 is provided with a plurality of evenly arranged mounting grooves 310, and the inner wall of the mounting grooves 310 is provided with internal threads 311.

[0045] The mounting slot 310 on the placement plate 1 can cooperate with the limiting block 312 to limit the workpiece and improve the stability of the workpiece.

[0046] In this embodiment of the utility model, a plurality of mounting slots 310 are respectively disposed on both sides of the first suction cup 301.

[0047] The mounting slots 310 are located on both sides of the first suction cup 301, which can fix workpieces of different shapes and improve the fixing effect of the workpieces.

[0048] In this embodiment of the utility model, two limiting blocks 312 are provided at the top of the placement plate 1, and the mounting groove 310 is threadedly connected to the limiting blocks 312 through the internal thread 311.

[0049] When the workpiece is adsorbed and fixed by the first suction cup 301, the limiting block 312 can be installed by the internal thread 311 in the mounting groove 310, and the installation can be adjusted according to the different workpieces.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
