[0002] With the development of science and technology, the use of automated equipment has become more and more popular. Pallets, as a carrier for handling and conveying products, also play an extremely important role. At present, pallets are widely used in automated conveying equipment. The utility model patent application number in the prior art is: 202121197743.4, and its name is a pallet for conveyor lines, including a carrier plate and a rectangular frame composed of multiple substrates inserted in sequence. The frame is fixedly connected to the carrier plate by positioning connectors and positioning pins. The side of the frame is provided with a buffer pad, a side sensor sheet and an anti-fool mechanism. The bottom of the frame is provided with a bottom sensor sheet, and the outer side of the frame is provided with a positioning card edge. A plurality of rectangularly arranged positioning pin sleeves are provided at the bottom of the carrier plate on the inside of the frame. Although the utility model pallet is assembled by assembling, when the size of the pallet is relatively special, this pallet needs to be customized for the entire frame, which wastes costs. Summary of the invention

[0003] Traditional pallet frames are usually composed of multiple bases inserted sequentially into a rectangular frame. This frame is complicated to assemble and disassemble and lacks flexibility. Moreover, when a pallet of a specific size needs to be customized, the entire frame structure must be redesigned, increasing production and maintenance costs. Therefore, a more convenient and economical pallet design is needed that can adapt to different needs without having to remake the entire pallet frame.

[0004] Based on this, the present invention proposes a new pallet design, which uses truncated side frames and L-shaped corner pieces to achieve assembly, so that the size of the pallet can be quickly adjusted according to different needs, reducing manufacturing and maintenance costs. In addition, the friction strip at the bottom of the rectangular frame enhances the wear resistance, and the placement groove in the middle of the side frame fixes the support plate with screws and nuts, further enhancing the stability of the pallet. By setting the clearance port, the stopper can pass through any of the clearance ports, effectively preventing the movement of the pallet, enhancing the control accuracy, and realizing the efficient, flexible and stable operation of the pallet on the automated conveyor line.

[0005] The technical solution adopted by the present invention is a pallet, which comprises a rectangular frame and a supporting plate, wherein the supporting plate is located in the rectangular frame.

[0006] Furthermore, the rectangular frame is composed of a rectangular first frame composed of four side frames and an L-shaped corner piece connecting two adjacent side frames.

[0007] Furthermore, a slot for plugging with a support plate is provided at the top of the side frame; and both sides of the cross section of the bottom of the side frame are L-shaped grooves.

[0008] Furthermore, the bottom cross-sections of both ends of the L-shaped corner piece are concave, and the concave shape is plug-fitted with the cross-section of the bottom of the side frame.

[0009] Furthermore, a friction strip is provided in the middle area of ​​the bottom of the side frame, the cross-sectional shape of the friction strip is the same as the bottom cross-sectional shape of the two ends of the L-shaped corner piece, and the side frame and the friction strip are arranged in parallel and plug-fitted.

[0010] Furthermore, the bottom lengths of both ends of the L-shaped corner piece are longer than the top of the L-shaped corner piece.

[0011] Furthermore, when the L-shaped corner piece is butted against the side frame, the top of the side frame and the top of the L-shaped corner piece together form a receiving groove for plugging into the support plate.

[0012] Furthermore, a placement groove for placing nuts is provided in the middle of the side frame, and the side frame and the supporting plate are fixed by screws and nuts.

[0013] Furthermore, a sensor sheet is provided on the side of the rectangular frame.

[0014] Furthermore, an upper edge of the sensor sheet is lower than an upper surface of the rectangular frame.

[0015] Furthermore, a plurality of positioning pin sleeves are provided at the bottom of the support plate.

[0016] The present invention discloses a pallet, which has the beneficial effect that compared with the prior art, the rectangular frame is composed of a side frame and an L-shaped corner piece, the top of the side frame is provided with a slot for plugging and cooperating with a pallet, and the bottom is provided with an L-shaped groove for plugging and cooperating with the L-shaped corner piece, so that the pallet can cut off the side frame as needed to adapt to different size requirements, thereby improving flexibility and applicability. Through the combined design of the rectangular frame and the pallet, the problem of the need for re-customization when the size of the pallet is special in the prior art is solved, and the cost is significantly reduced. In addition, the friction strip at the bottom of the rectangular frame enhances the wear resistance, and the placement groove in the middle of the side frame fixes the pallet with screws and nuts, further enhancing the stability of the pallet. By setting a clearance port, the stopper can pass through any of the clearance ports, effectively preventing the movement of the pallet, enhancing the control accuracy, and realizing the efficient, flexible and stable operation of the pallet on the automated conveyor line.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to further understand the content of the present invention, this technical solution is further explained below in conjunction with specific implementation methods.

[0029] Example 1: Figures 1 to 8As shown, this embodiment provides a pallet, including a rectangular frame and a pallet 4, wherein the pallet 4 is located in the rectangular frame. The rectangular frame is composed of a rectangular first frame composed of four side frames 1 and an L-shaped corner piece 3 connecting two adjacent side frames 1. A slot 11 for plugging with the pallet 4 is provided on the top of the side frame 1, the notch of the slot 11 faces the inside of the rectangular frame and the slot 11 is provided along the outer edge of the rectangular frame; the cross section of the bottom of the side frame 1 is L-shaped grooves 12 on both sides, and the bottom cross section of the two ends of the L-shaped corner piece 3 is concave 34, and the concave 34 is plugged into the cross section of the bottom of the side frame 1. The bottom lengths of the two ends of the L-shaped corner piece 3 are longer than the top of the L-shaped corner piece 3, that is, a step 31 is formed between the two ends of the bottom of the L-shaped corner piece 3 and the top of the L-shaped corner piece 3. When the L-shaped corner piece 3 is docked with the side frame 1, the end of the L-shaped groove 12 is inserted into the concave 34, and the end of the placement groove 13 is placed on the step 31. The top of the side frame 1 and the top of the L-shaped corner piece 3 together form a receiving groove 32 for plugging with the pallet 4. The side frame 1 and the friction strip 2 are both mold extrusion parts, which can be cut into any length as needed to adapt to different pallet requirements.

[0030] A sensing sheet 5 is provided on the side of the rectangular frame, and the sensing sheet 5 can complete the position detection and control of the pallet. The upper edge of the sensing sheet 5 is lower than the upper surface of the rectangular frame, which can prevent the sensing sheet 5 from contacting and rubbing with the conveyor line, thereby ensuring the accuracy of the sensing detection.

[0031] A plurality of positioning pin sleeves 6 are provided at the bottom of the support plate 4, which is convenient for replacement and maintenance of the positioning pin sleeves 6. For workstations with lifting and rotation, it is convenient to arrange the positions of the positioning pins, making the lifting and rotation structure simpler. The tray is driven to rotate by inserting the lifting and rotating positioning pins into the positioning pin sleeves 6, making the rotation of the tray smoother.

[0032] On this basis, a friction strip 2 is provided in the middle area of ​​the bottom of the side frame 1. The cross-sectional shape of the friction strip 2 is the same as the cross-sectional shape of the bottom of the two ends of the L-shaped corner piece 3. The side frame 1 and the friction strip 2 are arranged in parallel and plug-fitted. The friction strip 2 is made of PE plastic material to improve the wear resistance of the bottom of the rectangular frame in contact with the conveyor line.

[0033] In order to enhance the stability of the support plate 4 and the rectangular frame, a placement groove 13 for placing the nut 8 is provided in the middle of the side frame 1. After the screw 7 passes through the support plate 4 and the side frame 1 in sequence, the screw 7 is connected and matched with the nut 8 to fix the support plate 4 and the side frame 1.

[0034] Furthermore, if Figure 1 and Figure 2As shown, each of the four side frames 1 has a clearance opening 33 at the bottom, and each clearance opening 33 is staggered and distributed on the rectangular frame. The purpose of setting the clearance opening 33 and each clearance opening 33 is to facilitate the stopper to pass through any clearance opening 33 during the movement of the pallet on the conveyor line. After the stopper passes through the side frame 1 where the clearance opening 33 is located, the stopper prevents the side frame 1 parallel to the side frame 1 passed through from passing through.

[0035] In this embodiment, the rectangular frame is composed of a side frame 1 and an L-shaped corner piece 3. The top of the side frame 1 is provided with a slot 11 to be plugged into the pallet 4, and the bottom is provided with an L-shaped slot 12 to be plugged into the L-shaped corner piece 3, so that the pallet can be cut off from the side frame 1 as needed to adapt to different size requirements, thereby improving flexibility and applicability. The combined design of the rectangular frame and the pallet 4 solves the problem of the need for re-customization of pallets in the prior art when the size is special, thereby significantly reducing costs. By using the cuttable side frame 1 and the L-shaped corner piece 3 to achieve assembly, the size of the pallet can be quickly adjusted according to different needs, thereby reducing manufacturing and maintenance costs. In addition, the friction strip 2 at the bottom of the rectangular frame enhances wear resistance, while the placement slot 13 in the middle of the side frame 1 fixes the pallet 4 through screws 7 and nuts 8, further enhancing the stability of the pallet. By setting the clearance opening 33, the stopper can pass through any clearance opening 33, effectively preventing the movement of the pallet, enhancing control accuracy, and realizing efficient, flexible and stable operation of the pallet on the automated conveyor line.
