Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical automation, in particular to a transfer and positioning device. Background Art

[0002] With the development of society, the increase in labor costs and the rise of the automation industry, the widespread use of automation equipment has become an irreplaceable trend. During the product assembly or testing process, the product needs to be transferred to the standard operating position for the next step of processing, and the product needs to be clamped. At this time, a positioning and transfer device is needed.

[0003] In the prior art, the positioning and transfer device generally includes a positioning mechanism for positioning the product and a power device for driving the positioning mechanism to pass through the loading and unloading stations and non-loading and unloading stations. Among the positioning and transfer equipment on the market: one situation is that the entire equipment adopts an electric drive screw structure. Although this structure has good load-bearing capacity and high precision, the overall structure of the equipment is bulky, the cost is high, and the maintenance is complicated. Another way is to use a pneumatically driven linear guide structure. This method has a lower cost and a less complicated structure, but the positioning accuracy is poor, and the positioning mechanism is complex and mostly fixed.

[0004] In the actual assembly process, the workpiece is generally positioned by plane positioning. In order to ensure the precision and accuracy of the workpiece positioning, at least two directions of positioning are required during the workpiece positioning operation.

[0005] In view of the above problems, it is urgent to design a lightweight positioning and transfer device that can not only achieve high-precision positioning during the workpiece transfer process, but also reduce the cost and failure rate of the mechanism while ensuring the positioning accuracy of the workpiece. Utility Model Content

[0006] The purpose of the utility model is to provide a transfer and positioning device to solve the problems raised in the above background technology. The following technical solution is provided: a transfer and positioning device, comprising:

[0007] A support leg, the upper end of which is fixedly provided with a base, and baffles are respectively provided at both ends of the base;

[0008] A transfer mechanism, slidably arranged on the support legs, for transferring the workpiece;

[0009] A positioning mechanism, fixedly arranged on the transfer mechanism, and used for clamping the workpiece;

[0010] Buffers are respectively arranged on the end walls of the two baffles and are used to contact the transfer mechanism for buffering;

[0011] The limiter is fixedly arranged on the baffle plate and is used to limit the moving stroke of the transfer mechanism.

[0012] In the present technical solution, the transfer mechanism and the positioning mechanism are pneumatically driven. When the workpiece (the workpiece involved in the present application is the electrode of the lithium battery cover) is transferred and positioned, the electrode of the lithium battery cover to be assembled is placed in the positioning mechanism in the initial state, and then the positioning mechanism is started. After the positioning mechanism is started, the pneumatic device is used to push the electrode of the lithium battery cover to achieve preliminary clamping.

[0013] After the positioning mechanism completes clamping the workpiece, the transfer mechanism is started. The transfer mechanism is started to drive the positioning mechanism to move through linear motion until the electrode of the clamped lithium battery cover is transported to the assembly position for the next step of assembly.

[0014] In the process of transferring workpieces by horizontal movement of the transfer mechanism, since the transfer mechanism is driven pneumatically, when the transfer mechanism moves horizontally to the two ends of its stroke, in order to avoid collision between the transfer mechanism and the baffle, buffers and limiters are respectively set on the inner side walls of the two baffles. The buffer adopts hydraulic buffering to avoid collision between the transfer mechanism and the baffle and cause the workpiece to fall, thereby reducing the vibration of the entire device. In order to better control the end point of the movement stroke of the transfer mechanism and improve the accuracy of transfer, limiters are respectively set on the end walls of the baffle to adjust the horizontal stroke of the transfer mechanism.

[0015] In any of the above technical solutions, further, the transfer mechanism includes a linear guide rail fixedly set on a base, a displacement plate is slidably provided on the linear guide rail, a displacement cylinder is connected to one side of the displacement plate, the other end of the displacement cylinder is fixedly set on a baffle on one side of the base, and a throttling speed regulating valve for adjusting the air flow of the displacement cylinder is also provided at one end of the displacement cylinder.

[0016] In this technical solution, during the process of the transfer mechanism transferring the workpiece, the operator can adjust the air flow in the throttling control valve to achieve the power of the displacement cylinder when extending and contracting, thereby controlling the speed of movement and response speed of the transfer mechanism.

[0017] In any of the above technical solutions, further, the positioning mechanism includes a shell, which is fixedly arranged on the upper end surface of the displacement plate, a cover plate is provided on the upper end of the shell, a material opening is opened in the middle of the cover plate, and a second positioning port is also provided in the middle of the lower end surface of the shell. The second positioning port is used for positioning the workpiece. An inclined guide rail is fixedly provided at the lower end surface of the shell, a positioning block is slidably provided on the inclined guide rail, a limit block is provided on one side of the shell, and a spring is provided between the limit block and the positioning block. A first positioning port is provided at the other end of the positioning block, and the first positioning port is used for clamping the workpiece. A hoof-shaped protrusion is provided on one side of the positioning block. A positioning cylinder is also provided inside the shell, and one end of the positioning cylinder is always against the end surface of the hoof-shaped protrusion.

[0018] In this technical solution, the first positioning opening and the second positioning opening are designed as a concave right angle, and the first positioning opening and the second positioning opening form a rectangle. The moving direction of the positioning block coincides with the diagonal of the rectangle, and a diagonal positioning clamping method is adopted. During the clamping process, the device can well contact the edges and corners of the electrode of the square lithium battery cover plate to complete the clamping.

[0019] The material opening is aligned with the second positioning opening in the vertical direction during installation, thereby ensuring that the workpiece can be smoothly placed into the second positioning opening for positioning contact therewith.

[0020] The lower end of the workpiece is in a rectangular shape. When clamping, two diagonal portions of the workpiece are in contact with the first positioning opening and the second positioning opening respectively, thereby realizing diagonal positioning and clamping of the workpiece.

[0021] When the positioning cylinder is started, it drives the positioning block to slide along the inclined guide rail. At this time, the positioning block moves away from the second positioning port and compresses the spring, so that the electrode workpiece of the lithium battery cover can be placed from the cover to the second positioning port. Then the positioning cylinder contracts, and the spring pushes the positioning block to reset under the action of elastic force, thereby realizing rapid clamping of the electrode workpiece of the lithium battery cover.

[0022] Preferably, a positioning sensor can be additionally provided at the positioning cylinder, and the positioning sensor can replace manual work to quickly identify whether the electrodes of the lithium battery cover plate or other workpieces are clamped in place, thereby improving the working efficiency of the entire device.

[0023] The beneficial effects of the utility model are as follows: by setting up the transfer mechanism, using pneumatic transmission, adding limiters at both ends of its stroke to achieve limit adjustment of its movement stroke, and setting buffers on both sides, hydraulically buffering the transfer mechanism when it moves to the maximum stroke on both sides, ensuring the stability of the device. The positioning mechanism adopts a diagonal positioning clamping method to achieve rapid clamping of the electrodes of the lithium battery cover plate, improving the positioning accuracy during the workpiece transfer process, and the mechanism is low in complexity, making the entire device structure lightweight, with a low failure rate and easy maintenance and maintenance.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, this embodiment provides a transfer and positioning device, including:

[0034] A support leg 10, a base 11 is fixedly provided at the upper end of the support leg 10, and baffles 12 are respectively provided at both ends of the base 11;

[0035] The transfer mechanism 20 is slidably disposed on the support leg 10 and is used for transferring the workpiece 70;

[0036] The positioning mechanism 30 is fixedly arranged on the transfer mechanism 20, and the positioning mechanism 30 is used for positioning and clamping the workpiece 70;

[0037] The buffer 40 is respectively arranged on the end walls of the two baffles 12 and is used to contact the transfer mechanism 20 for buffering;

[0038] The limiter 50 is fixedly disposed on the baffle 12 and is used to limit the moving stroke of the transfer mechanism 20 .

[0039] In the present technical solution, the transfer mechanism 20 and the positioning mechanism 30 are pneumatically driven. When the workpiece (the workpiece involved in the present application is the electrode of the lithium battery cover) is transferred and positioned, the electrode of the lithium battery cover to be assembled is placed in the positioning mechanism 30 in the initial state, and then the positioning mechanism 30 is started. After the positioning mechanism 30 is started, the pneumatic device is used to push the electrode of the lithium battery cover to achieve preliminary clamping;

[0040] After the positioning mechanism 30 completes clamping the workpiece 70, the transfer mechanism 20 is started. The transfer mechanism 20 drives the positioning mechanism 30 to move through linear motion until the clamped lithium battery cover electrode is transported to the assembly position for the next assembly step.

[0041] During the horizontal movement of the transfer mechanism 20 to transfer the workpiece, since the transfer mechanism 20 is driven pneumatically, when the transfer mechanism 20 moves horizontally to the two ends of its stroke, in order to avoid the collision between the transfer mechanism 20 and the baffle 12, a buffer 40 and a stopper 50 are respectively provided on the inner side walls of the two baffles 12. The buffer 40 adopts a hydraulic buffering method to avoid the collision between the transfer mechanism 20 and the baffle 12 causing the workpiece to fall, thereby reducing the vibration of the entire device. In order to better control the end point of the movement stroke of the transfer mechanism 20 and improve the accuracy of the transfer, the stopper 50 is respectively provided on the end wall of the baffle 12 to adjust and limit the horizontal stroke of the transfer mechanism 20.

[0042] In a preferred embodiment of the present invention:

[0043] like Figure 2 As shown, specifically, the transfer mechanism 20 includes a linear guide rail 21, which is fixedly arranged on the base 11, and a displacement plate 22 is slidably arranged on the linear guide rail 21. A displacement cylinder 23 is connected to one side of the displacement plate 22, and the other end of the displacement cylinder 23 is fixedly arranged on the baffle 12 on one side of the base 11, and a throttling speed regulating valve 24 for adjusting the airflow of the displacement cylinder 23 is also provided at one end of the displacement cylinder 23.

[0044] In the present technical solution, during the process of the transfer mechanism 20 transferring the workpiece, the operator can adjust the air flow in the throttling control valve 24 to achieve the power of the displacement cylinder 23 when extending and contracting, thereby controlling the speed of movement and response speed of the transfer mechanism 20.

[0045] In a preferred embodiment of the present invention:

[0046] like Figure 2-5 As shown, specifically, the positioning mechanism 30 includes a shell 31, which is fixedly arranged at the upper end surface of the displacement plate 22. A cover plate 32 is provided at the upper end of the shell 31, and a material port 33 is opened in the middle of the cover plate 32. A second positioning port 63 is also provided in the middle of the lower end surface of the shell 31, and the second positioning port 63 is used for positioning the workpiece 70. An inclined guide rail 34 is fixedly provided at the lower end surface of the shell 31, and a positioning block 35 is slidably provided on the inclined guide rail 34. A limit block 36 is provided on one side of the shell 31, and a spring 37 is provided between the limit block 36 and the positioning block 35. A first positioning port 62 is provided at the other end of the positioning block 35, and the first positioning port 62 is used for clamping the workpiece. A hoof-shaped protrusion 61 is provided at one side of the positioning block 35. A positioning cylinder 38 is also provided inside the shell 31, and one end of the positioning cylinder 38 is always against the end surface of the hoof-shaped protrusion 61.

[0047] In the present technical solution, the first positioning opening 62 and the second positioning opening 63 are designed to be inwardly concave right angles, and a rectangle is formed between the first positioning opening 62 and the second positioning opening 63. The moving direction of the positioning block 35 coincides with the diagonal line of the rectangle, and a diagonal positioning clamping method is adopted, so that the device can well contact the edges and corners of the electrode of the square lithium battery cover plate during the clamping process to complete the clamping.

[0048] The material opening 33 is aligned vertically with the second positioning opening 63 during installation, thereby ensuring that the workpiece 70 can be smoothly placed into the second positioning opening 63 for positioning contact therewith.

[0049] The lower end of the workpiece 70 is in a rectangular shape. When clamping, two diagonal portions of the workpiece 70 are in contact with the first positioning opening 62 and the second positioning opening 63 respectively, thereby achieving diagonal positioning and clamping of the workpiece 70 .

[0050] When the positioning cylinder 38 is started, it drives the positioning block 35 to slide along the inclined guide rail 34. At this time, the positioning block 35 deviates from the second positioning port 63 and compresses the spring 37, so that the electrode workpiece of the lithium battery cover can be placed from the cover 32 to the second positioning port 63. Then the positioning cylinder 38 contracts, and the spring 37 pushes the positioning block 35 to reset under the action of elastic force, thereby realizing the rapid clamping of the electrode workpiece of the lithium battery cover.

[0051] Preferably, a positioning sensor can be additionally provided at the positioning cylinder 38, and the positioning sensor can replace manual work to quickly identify whether the electrodes of the lithium battery cover plate or other workpieces are clamped in place, thereby improving the working efficiency of the entire device.

[0052] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
