Description

Technical Field

[0001] The invention relates to the technical field of transfer and lifting equipment, and in particular to a transfer and lifting equipment for an automobile assembly workshop. Background Art

[0002] The automobile assembly workshop is where the painted car body is turned into a finished car. Usually, a car needs to be assembled with about 1,000-2,000 parts in the general assembly workshop. There are many types of parts and many types of assembly processes, which makes this workshop the workshop with the most types of equipment. The general assembly line consists of interior lines, chassis lines, exterior lines, door lines, inspection lines, rain lines, etc. The assembly of automotive battery liquid cooling plates is an important link in the thermal management system of new energy vehicle batteries. It ensures that the battery can work efficiently and permanently within a suitable temperature range (25-45°C) and ensures that the temperature difference between battery cells and modules is as small as possible. The main function of the liquid cooling plate is to help the battery dissipate heat by contacting the coolant and keep the battery temperature stable. In the automobile assembly workshop, the battery liquid cooling plate needs to be continuously transferred to implement continuous processing and assembly operations.

[0003] The transfer and lifting equipment is a device used to change the conveying direction of items. It adopts four-point balanced lifting and can be lifted smoothly without obstruction or jamming. In the automobile assembly workshop, it is used to transfer workpieces to different workstations to improve production efficiency. The existing transfer and lifting equipment used in automobile assembly workshops can only transfer one battery liquid cooling plate at a time during the transfer of the battery liquid cooling plate, and the transfer efficiency is low. If you want to transfer multiple battery liquid cooling plates at the same time, the battery liquid cooling plates need to be stacked. In the process of moving multiple battery liquid cooling plates, it is easy to cause the battery liquid cooling plates to shake during the transfer process, and the stability during the transfer process cannot be guaranteed. Therefore, the present application provides a transfer and lifting equipment for automobile assembly workshops to meet the needs. Summary of the invention

[0004] In view of the above problems, the present application provides a transfer and lifting device for an automobile assembly workshop.

[0006] It also includes a positioning unit arranged on the material transfer unit. When the material loading unit carrying the workpiece moves to the position directly below the material transfer unit, the positioning unit moves to the position directly below the workpiece inside the material loading unit.

[0007] The positioning unit is provided with a jacking structure that can control the workpiece to rise. After the workpiece rises and disengages from the loading unit, the transfer unit can grasp the workpiece and perform the transfer operation of the workpiece.

[0008] Further, the loading unit includes a moving table that can accommodate the workpiece. The moving table is provided with a channel that can accommodate the movement of the jacking structure, and two connecting seats one are provided at the bottom end of the moving table and can move synchronously with it.

[0009] A pair of pressure rods in a U-shaped structure are provided on the moving table. When the moving table carries the workpiece, the two symmetric legs of the pressure rod rotate above the workpiece.

[0010] Further, driving gears one are provided on the straight rod parts connecting the two legs of the pressure rod. The driving gears one are meshed with driving gears two.

[0011] Further, the jacking structure includes a jacking seat corresponding to the channel, a cylinder that can control the movement of the jacking seat in the channel, and two groups of limiting rods stored under the jacking seat. The number of each group of limiting rods is two. A group of limiting rods on the same side are fixed by a connecting rod, and a motor that can control its rotation is provided on the connecting rod.

[0012] The limiting rods are all in an L-shaped structure. When the workpiece rises and disengages from the moving table, the rod bodies of the limiting rods are exposed above the jacking seat and are perpendicular to the jacking seat.

[0013] Further, the positioning unit includes a movable support seat and two connecting seats two provided at the bottom end of the support seat. The jacking seat is located directly above the support seat, and the cylinder is provided under the support seat. When the limiting rods are stored under the jacking seat, the limiting rods are located in the sandwich space formed by the jacking seat and the support seat.

[0014] Further, the transfer unit includes a placement rack and two transverse guide racks distributed in parallel. Electrically controlled traction gears one and two are provided inside the placement rack. The electrically controlled traction gears one and two are connected by a synchronous chain. In the natural state, the two parallel chain bodies of the synchronous chain are parallel to the two transverse guide racks. Two connecting seats one are respectively provided on the chain body of the transverse guide rack with the farthest distance, and two connecting seats two are respectively provided on the transverse guide rack and the chain body with the closest distance.

[0015] Further, the guiding frame includes a frame body and a first guide rail and a first rack provided on the frame body. The first guide rail and the first rack are distributed in parallel.

[0016] Furthermore, the transfer unit includes a transverse moving platform that can move along the distribution direction of the first guide rail, a power gear 1 adapted to the first rack, a power gear 2 vertically distributed to the power gear 1, a second rack meshing with the power gear 2, and a linkage frame connected to the second rack.

[0017] A lifting platform is provided at the bottom end of the linkage frame, on which a second guide rail, two clamping frames that can move along the distribution direction of the second guide rail, and a cylinder that can control the movement of the two clamping frames are provided.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. 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. Embodiment 1:

[0036] Reference Figure 1-11 Shown is a transfer and lifting device for an automobile assembly workshop, which includes a loading unit 3 capable of carrying workpieces, a material transfer unit 1 capable of driving the loading unit 3 to move, and a transfer unit 2 capable of moving the workpieces to different workstations. The transfer unit 2 is located above the material transfer unit 1, and a guiding frame 5 adapted thereto is provided on the transfer unit 2. When the automotive battery liquid cooling plate (hereinafter referred to as the workpiece) is processed at a certain workstation, multiple workpieces can be stacked on the loading unit 3. The material transfer unit 1 can cause the loading unit 3 and the multiple workpieces to move to directly below the transfer unit 2. The transfer unit 2 can simultaneously grasp the workpieces and travel on the guiding frame 5 until it reaches above different workstations, and place the grasped workpieces on another workstation. In this process, the efficiency of workpiece transfer is improved.

[0037] In order to ensure that the transfer unit 2 can comprehensively grasp multiple workpieces and prompt the workpieces to quickly separate from the loading unit 3, a positioning unit 4 is provided on the material transfer unit 1. When the loading unit 3 carrying the workpieces moves to directly below the transfer unit 2, the positioning unit 4 moves to directly below the workpiece inside the loading unit 3. A jacking structure for controlling the rise of the workpiece is provided on the positioning unit 4. After the workpiece rises and separates from the loading unit 3, the transfer unit 2 quickly grasps multiple workpieces to implement the transfer operation of the workpieces.

[0038] The loading unit 3 includes a moving table 31 that can accommodate the workpiece to be placed. The moving table 31 is provided with a channel 32 that can accommodate the movement of the jacking structure, and two connecting seats one 33 that can move synchronously with it are provided at the bottom of the moving table 31. A pair of pressure bars 34 in a U-shaped structure are provided on the moving table 31. When the moving table 31 carries the workpiece, the two symmetric legs of the pressure bar 34 rotate above the workpiece. To maintain the stability of the stacked multiple workpieces and prevent the workpieces from shaking and shifting during the movement close to the transfer unit 2, so as to facilitate the subsequent jacking operation.

[0039] Drive gears one 35 are provided on the straight rod portions connecting the two legs of the pressure bar 34. The drive gears one 35 are meshed with drive gears two 36. When the drive gears two 36 rotate, the drive gears one 35 and the straight rod portions of the pressure bar 34 rotate, so as to achieve the purpose of rotating the two symmetric legs of the pressure bar 34 above the workpiece. A power shaft 37 that can rotate synchronously with it is provided at the central axis position of the drive gear two 36, and a drive motor 38 for controlling its rotation is connected to the end of the power shaft 37. The drive motor 38 provides the power source for the rotation of the power shaft 37 and the drive gears two 36. Embodiment 2:

[0040] Such as Figure 2-9As shown, the lifting structure includes a lifting seat 41 corresponding to the channel 32, a cylinder that can control the movement of the lifting seat 41 in the channel 32, and two sets of limit rods 44 received under the lifting seat 41. When the cylinder drives the lifting seat 41 to rise inside the channel 32, the pressure rod 34 rotates away from the workpiece, leaving space for the workpiece to rise smoothly.

[0041] There are two limit rods 44 in each group. The limit rods 44 in the same group are fixed by connecting rods. The connecting rods are provided with motors that can control their rotation. The limit rods 44 are all L-shaped. When the workpieces rise and leave the moving platform 31, the motors are turned on. Under the connection of the connecting rods, the rod bodies of the limit rods 44 are exposed above the lifting seat 41 and are perpendicular to the lifting seat 41, so as to clamp the multiple stacked workpieces and maintain the stability of the workpieces.

[0042] Therefore, in the process of the transfer unit 2 grabbing multiple workpieces at the same time, the stacked multiple workpieces can be effectively prevented from shaking, shifting, etc. due to the top-touching force of the transfer unit 2 during the grabbing operation, thereby improving the stability of the stacked multiple workpieces during the grabbing process by the transfer unit 2, improving the tightness of the connection between the workpiece and the transfer unit 2 during the grabbing operation, and the grabbing accuracy, thereby ensuring the stability of the transfer unit 2 after grabbing the multiple workpieces and moving them.

[0043] The positioning unit 4 includes a movable support seat 42 and two connecting seats 43 arranged at the bottom end of the support seat 42. The lifting seat 41 is located directly above the support seat 42, and the cylinder is arranged below the support seat 42. When the limit rod 44 is stored below the lifting seat 41, the limit rod 44 is located in the interlayer space formed by the lifting seat 41 and the support seat 42. Therefore, when the lifting seat 41 lifts multiple workpieces, the limit rod 44 does not affect the smooth rise of the lifting seat 41, and can rise synchronously with the lifting seat 41 until the multiple workpieces are separated from the moving platform 31, and the limit rod 44 rotates to clamp the multiple workpieces.

[0044] The material transfer unit includes a placing rack 11 and two transverse guide racks 15 which are distributed in parallel. An electric-controlled traction gear 12 and an electric-controlled traction gear 2 13 are arranged in the placing rack 11. The electric-controlled traction gear 12 and the electric-controlled traction gear 2 13 are connected by a synchronous chain 14. In a natural state, two parallel chain bodies of the synchronous chain 14 are parallel to the two transverse guide racks 15. Two connecting seats 1 33 are respectively arranged on the chain body of a transverse guide rack 15 with the farthest spacing, and two connecting seats 2 43 are respectively arranged on a transverse guide rack 15 and the chain body with the closest spacing.

[0045] Therefore, when the electrically-controlled traction gear 1 12 and the electrically-controlled traction gear 2 13 pull the synchronous chain 14 to rotate, the two connecting seats 1 33 and the two connecting seats 2 43 can move closer until the lifting seat 41 moves to the bottom of the moving platform 31 and corresponds to the channel 32, thereby performing lifting operations on multiple workpieces.

[0046] The movable positioning unit 4 and loading unit 3 are provided, so that the positioning unit 4 and the loading unit 3 have the advantages of flexible separation and docking, which is conducive to the maintenance and repair operations of the loading unit 3 and the positioning unit 4. When the moving platform 31 is loaded with multiple workpieces and moves, the positioning unit 4 is separated from it. Since the channel 32 opened on the moving platform 31 is in an exposed state, placing multiple workpieces on the moving platform 31 can reduce the load of the loading unit 3 during the movement process, and effectively improve the operation speed and accuracy of the loading unit 3. When the loading unit 3 moves to the bottom of the transfer unit, the lifting seat 41 automatically docks with the channel 32, and the lifting operation of the workpiece can be smoothly implemented. Embodiment 3:

[0047] like Figure 1-7 As shown, in order to maintain the stability of the transfer unit 2 during movement, the guide frame 5 includes a frame body 51 and a first guide rail 52 and a first rack 53 provided on the frame body 51. The first guide rail 52 and the first rack 53 are distributed in parallel.

[0048] The transfer unit 2 includes a traverse machine 21 that can move along the distribution direction of the first guide rail 52, a power gear 1 22 matched with the first rack 53, a power gear 23 vertically distributed with the power gear 1 22, a second rack 26 meshed with the power gear 23, and a linkage frame 25 connected with the second rack 26. When the power gear 1 22 is running, under the meshing force between the power gear 1 22 and the first rack 53, the traverse machine 21 can move on the first guide rail 52, and then the remaining structures installed on the traverse machine 21 can be moved synchronously until the traverse machine 21 moves to above different processing stations.

[0049] Then, the second power gear 23 operates, and under the meshing force between the second power gear 23 and the second rack 26, the linkage frame 25 can be lowered to the workstation. Since the bottom end of the linkage frame 25 is provided with an elevator platform 24, the elevator platform 24 can be lowered to the workstation as the linkage frame 25 moves downward. The elevator platform 24 is provided with a second guide rail 27, two clamping frames 28 that can move along the distribution direction of the second guide rail 27, and a cylinder that can control the movement of the two clamping frames 28. When the two clamping frames 28 are close to the limit rod 44 to open and close, the workpieces can be put in and grabbed until multiple workpieces are placed on the workstation for further processing operations.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
