[0033] like Figures 1 to 12 As shown, the present embodiment discloses a multifunctional workbench with electric lifting and tilting, comprising a frame 1 and an assembly platform 2 constructed of aluminum profiles, wherein the assembly platform 2 is connected above the frame 1, and the frame 1 comprises a base frame 11, a top frame 12 and a telescopic frame 13, wherein the base frame 11 and the top frame 12 are arranged in parallel, the top frame 12 is located above the base frame 11, and the base frame 11 and the top frame 12 are connected via the telescopic frame 13; a lifting mechanism 3 for driving the lifting and lowering movement of the top frame 12 is provided in the frame 1, the lifting mechanism 3 is mounted on the base frame 11, and the lifting end of the lifting mechanism 3 is connected to the top frame 12; an inclination adjustment mechanism 4 for adjusting the inclination angle of the assembly platform 2 is also provided in the frame 1, the inclination adjustment mechanism 4 is mounted on the telescopic frame 13 or the top frame 12, and the action end of the inclination adjustment mechanism 4 is connected to the assembly platform 2. The frame 1 and the assembly platform 2 of the present embodiment are both constructed of aluminum profiles, and the aluminum profiles with the same structure are used, so that the types of parts of the workbench are reduced, and the construction of the frame 1 and the assembly platform 2 is more convenient. In addition, the frame 1 is configured as a modular structure of a base frame 11, a top frame 12 and a telescopic frame 13, so that after the frame 1 is disassembled, the base frame 11, the top frame 12 and the telescopic frame 13 are formed. These modules can be stacked, so that after the workbench is disassembled as a whole, each component can be placed flat, and the packaging space is greatly reduced, making product packaging and transportation convenient. After the workbench components are transported to the destination, it is only necessary to assemble the component modules, and the convenience of disassembly and assembly is relatively high.

[0034] In this embodiment, the lifting mechanism 3 includes four telescopic push rods that move synchronously. The circuits of the four telescopic push rods are connected to the same control circuit board. The four telescopic push rods are controlled to move synchronously through the control circuit board. In order to improve the synchronization of the telescopic push rod movement, each telescopic push rod is equipped with an encoder. The encoder feeds back the action signal of the telescopic push rod to the control circuit board. The control circuit board adjusts the synchronous movement of the telescopic push rod according to the signal fed back by the encoder to ensure the synchronous movement accuracy of the telescopic push rod. Specifically, the encoder can detect the speed of the telescopic push rod. Each encoder feeds back the speed signal detected by the telescopic push rod to the control circuit board. The control circuit board compares the speed signals detected by each encoder. If there is a speed difference between the telescopic push rods, the speed of the telescopic push rod is adjusted accordingly to synchronize them. The encoder can also detect the position of the telescopic push rod and feed back the detected position information to the control circuit board. The control circuit board compares the position information detected by each encoder. If there is a difference in the position between the telescopic push rods, the position of each telescopic push rod is synchronized by adjusting the set speed of the telescopic push rod. In addition, the control circuit board of this embodiment also has a WiFi module. After the WiFi module is connected to the network, the workbench can be remotely controlled. Correspondingly, the control circuit board can also be configured with a Bluetooth module, an infrared module, etc., so that it can be remotely controlled by a remote controller.

[0035] In this embodiment, the tilt adjustment mechanism 4 includes two telescopic push rods that act synchronously. Similarly, the two telescopic push rods are circuit-connected to the same control circuit board, and the two telescopic push rods are controlled by the control circuit board to synchronously telescope. The control principle of the telescopic push rods in the tilt adjustment mechanism 4 is the same as the control principle of the lifting mechanism 3.

[0036] In this embodiment, the telescopic frame 13 includes an inner frame 14 and an outer frame 15, wherein the inner frame 14 is located inside the outer frame 15, and the upper and lower ends of the inner frame 14 and the outer frame 15 are connected to the bottom frame 11 and the top frame 12. The bottom frame 11 and the top frame 12 are supported and guided by the inner frame 14 and the outer frame 15, so that when the lifting mechanism 3 drives the top frame 12 to move up and down, under the dual guidance of the inner frame 14 and the outer frame 15, the top frame 12 moves up and down more smoothly, and the lifting and lowering movement is more accurate, so that the assembled products placed on the assembly platform 2 are better protected, and the problems of loosening, disorder or damage of the assembled products caused by the unstable lifting of the assembly platform 2 are avoided. Specifically, the inner frame 14 and the outer frame 15 are both quadrilateral frame structures. The inner frame 14 includes four groups of first telescopic sleeve rods 16, which are vertically arranged between the bottom frame 11 and the top frame 12 to form four columns of the quadrilateral frame. The first telescopic sleeve rod 16 includes a first plug rod 161 and a first rod sleeve 162. The first rod sleeve 162 is provided with a socket adapted to the first plug rod 161. One end of the first plug rod 161 is fixedly connected to the top frame 12, one end of the first rod sleeve 162 is fixedly connected to the bottom frame 11, and the other end of the first plug rod 161 is connected from the first The other end of the rod sleeve 162 is inserted into the socket for matching connection; similarly, the outer frame 15 includes four sets of second telescopic sleeve rods 17, which are vertically arranged between the bottom frame 11 and the top frame 12 to form four uprights of a quadrilateral frame. The second telescopic sleeve rods 17 include a second plug rod 171 and a second rod sleeve 172. One end of the second plug rod 171 is fixedly connected to the bottom frame 11, one end of the second rod sleeve 172 is fixedly connected to the top frame 12, and the other end of the second rod sleeve 172 is inserted from the other end of the second plug rod 171 and sleeved on the outside of the second plug rod 171. By setting the first telescopic sleeve rod 16 and the second telescopic sleeve rod 17 in a reverse sleeve relationship, the guiding stability of the top frame 12 during the lifting movement is further improved. In addition, in order to improve the stability of the four groups of first telescopic rods 16 and the four groups of second telescopic rods 17, a supporting connecting rod 18 is provided between two adjacent first rod sleeves 162, and the outer sides of the four groups of first telescopic rods 16 are connected by four supporting connecting rods 18 to form a quadrilateral frame structure; similarly, a supporting connecting rod 18 is also provided between two adjacent second rod sleeves 172, and the outer sides of the four groups of second telescopic rods 17 are connected by four supporting connecting rods 18 to form a quadrilateral frame structure. In this way, the four groups of first telescopic rods 16 and the four groups of second telescopic rods 17 are all kept vertically arranged to ensure the balance of the lifting and lowering adjustment of the workbench.

[0037] As a preferred embodiment, in order to make the frame 1 and the assembly platform 2 simple and convenient to build, the cross-section of the aluminum profile is a square structure, and the four sides of the aluminum profile are the same. Therefore, when using the aluminum profile, there is no need to distinguish the side direction of the aluminum profile, and it can be used in any direction. The aluminum profile is a hollow structure, and the sides of the aluminum profile are all provided with a connecting groove 51 that opens outward. The opening of the connecting groove 51 is provided with a limiting convex strip 52. The limiting convex strip 52 is arranged on both sides of the opening of the connecting groove 51, so that the opening of the connecting groove 51 is smaller than the groove width of the connecting groove 51, so that the connecting nut can be placed in the connecting groove 51. Under the action of the limiting boss, the nut is limited in the connecting groove 51, and then connected to another aluminum profile through a connecting piece, so that the connection between the aluminum profiles is more flexible and convenient, and can be connected and adjusted at any position in the length direction of the aluminum profile. In addition, in order to make the telescopic movement of the first telescopic sleeve rod 16 and the second telescopic sleeve rod 17 smoother and reduce friction, the first plug rod 161, the first rod sleeve 162, the second plug rod 171 and the second rod sleeve 172 are all made of aluminum profiles, and the aluminum profiles of the first plug rod 161 and the second plug rod 171 are of aluminum profile specifications with a cross section smaller than the cross section of the hollow part of the aluminum profiles of the first rod sleeve 162 and the second rod sleeve 172. The roller assembly 19 is installed in the connecting groove 51 outside the first plug rod 161 and the second plug rod 171, and the roller assembly 19 is arranged along the length direction of the connecting groove 51, so that when the first plug rod 161 is connected to the first rod sleeve 162, the roller assembly 19 contacts the inner wall of the first rod sleeve 162, so that when the two move relative to each other, there is rolling friction between each other, the friction is small, the telescopic movement is smoother, and the lifting and lowering adjustment of the workbench is more accurate and stable. Similarly, when the second plug rod 171 and the second rod sleeve 172 are connected, rolling friction is also achieved through the contact of the roller assembly 19.

[0038] In this embodiment, one end of the bottom of the assembly platform 2 is connected to the top frame 12, the action end of the inclination adjustment mechanism 4 is connected to the middle position of the bottom of the assembly platform 2, and the other end of the bottom of the assembly platform 2 is provided with a support seat 21. The support seat 21 can make the assembly platform 2 lie flat and support and limit the top frame 12 when it descends to a low position, so that the assembly platform 2 is balanced above the top frame 12, avoiding the assembly platform 2 from colliding with the top frame 12 due to excessive descending.

[0039] In this embodiment, in order to prevent the workpiece from being worn when it moves on the assembly platform 2, a plurality of rolling balls 22 are provided on the top of the assembly platform 2, and the plurality of rolling balls 22 are distributed at intervals on the assembly platform 2. The workpiece is placed on the assembly platform 2, and the assembly platform 2 contacts the workpiece through the rolling balls 22. When the workpiece moves on the assembly platform 2, the rolling balls 22 enable the workpiece to move 360 ​​degrees on the assembly platform 2, thereby improving the flexibility and convenience of workpiece assembly, making the movement of the workpiece more labor-saving, and reducing the labor intensity of the staff. Specifically, a plurality of rolling ball mounting holes 23 are provided on the assembly platform 2, and the aperture of the rolling ball mounting hole 23 is larger than the outer diameter of the rolling ball 22. The rolling ball 22 is movably mounted on the ball seat 24, and the ball seat 24 is mounted in the rolling ball mounting hole 23. The rolling ball mounting hole 23 can be adapted to the installation of rolling balls 22 with different outer diameters, and the staff can install rolling balls 22 with different outer diameters according to work requirements.

[0040] In this embodiment, in order to make the assembly platform 2 suitable for the assembly of workpieces of different sizes, an extension bracket 6 and an extension frame 7 are respectively provided on the front and rear sides of the assembly platform 2. When the workpiece is assembled, the staff stands in front of the assembly platform 2. Therefore, the extension bracket 6 is provided on the front side of the assembly platform 2 to support the workpiece and prevent the workpiece from slipping and causing harm to the staff. Specifically, the extension bracket 6 includes a first extension telescopic rod 61, a first supporting cross bar 62 and a receiving rolling plate 63. One end of the first extension telescopic rod 61 is movably plugged into the front side of the assembly platform 2, the first supporting cross bar 62 is fixedly connected to the other end of the first extension telescopic rod 61, and the receiving rolling plate 63 is vertically arranged on the side of the first supporting cross bar 62 away from the first extension telescopic rod 61. When the assembly platform 2 is adjusted to the tilted state, the workpiece slides onto the receiving rolling plate 63 and is supported by the receiving rolling plate 63. In order to facilitate the movement of the workpiece on the receiving rolling plate 63, the receiving rolling plate 63 is provided with a plurality of arranged rotating rollers 64, and the rotating rollers 64 are arranged on the side of the receiving rolling plate 63 facing the assembly platform 2. Similarly, the extension frame 7 includes a second extension telescopic rod 71 and a second supporting cross bar 72, one end of the second extension telescopic rod 71 is movably plugged into the front side of the assembly platform 2, and the second supporting cross bar 72 is fixedly connected to the other end of the second extension telescopic rod 71. Both the first extension telescopic rod 61 and the second extension telescopic rod 71 can be telescopically moved relative to the assembly platform 2, thereby expanding the assembly area of ​​the assembly platform 2.

[0041] In addition, when the assembly and processing of a product requires a longer workbench, multiple workbenches can be spliced ​​together to form a processing line whose length meets the assembly and processing requirements. The splicing flexibility of the workbench is high and can adapt to the assembly and processing requirements of different products. When multiple workbenches are spliced ​​together to form a processing line whose length meets the assembly and processing requirements, the lifting and lowering adjustment and inclination adjustment of each workbench are synchronized. For example, the lifting mechanism 3 of each workbench has four telescopic push rods, and the inclination adjustment mechanism 4 has two telescopic push rods; after the three workbenches are spliced ​​together, the twelve telescopic push rods in the lifting mechanism 3 move synchronously; the six telescopic push rods in the inclination adjustment mechanism 4 move synchronously. Similarly, when more workbenches are spliced ​​together, the telescopic push rods of the lifting mechanisms of all workbenches move synchronously, and the telescopic push rods of the inclination adjustment mechanisms of all workbenches also move synchronously.

[0042] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the protection scope of the present invention.
