【技术领域】[Technical Field]

The invention relates to the field of machinery, in particular to a multi-station pipe shrinkage device.

【背景技术】【Background technique】

With the continuous deepening of the automation process, the assembly manufacturing industry continues to develop in the direction of high quality, high efficiency and high intelligence. At present, under the production technology conditions in China, many manufacturers still rely on the number of machines and labor to increase production, relying on experienced technicians to ensure the quality of products, which will inevitably increase labor and equipment costs. For example, in a cylindrical lithium battery assembly process, it is necessary to insert a battery cell together with a tab into a pipe that is open at both ends, and then press the compression port at both ends of the pipe, since the punch cannot be damaged during the punching process, and the stamping is satisfied. Molding requirements, etc., put forward higher requirements for mechanics, equipment and production processes. The traditional assembly method is to first stamp one end of the pipe. After the stamping is completed, the battery is installed and the other end is punched.

First, the first stamping is done on one machine, then the product is taken out, and then the second stamping, the third stamping, and the fourth stamping are sequentially performed on the other three machines. This punching and pressing process not only requires repeated assembly by the worker, but also takes a long time, and each time it is checked whether the ear is squared to prevent being crushed, and the production efficiency is low.

The features of the following embodiments and the embodiments may be combined with each other without conflict. In addition, the directional terms used in the present invention, such as "upper" and "lower", are used to better describe the various embodiments, and are not intended to limit the scope of the present invention.

Please refer to FIGS. 1 to 4, which illustrate a multi-station tube shrinkage device according to an embodiment of the present invention. The multi-station tube necking apparatus may include a lower mold assembly 10, a feed assembly, a plurality of upper mold assemblies 30 spaced apart from each other, and a stamping cylinder 40.

The lower die assembly 10 is configured to receive the pipe to be shrunk, and the number thereof may be one or more, wherein the plurality of lower die assemblies 10 are disposed independently of each other. As shown in FIG. 5, each lower die assembly 10 is provided with a receiving cavity for receiving the pipe to be shrunk, and the shape of the receiving cavity is adapted to the shape of the pipe to be shrunk, for example, when the pipe to be shrunk is When the cylindrical tube A with the cell of the tab B is inserted, the accommodating cavity may correspond to a cylindrical cavity, and the tube is inserted into the accommodating cavity and fixed in the accommodating cavity. Each of the lower mold assemblies 10 can be provided with a plurality of accommodating cavities, so that the plurality of tubes to be shrunk can be punched and compressed at one time. For example, as shown in FIG. 5, each of the lower mold assemblies 10 can be provided with four capacities. The chambers are disposed in a direction perpendicular to the line of sight of the lower mold assembly 10, and the four receiving cavities are located at four vertices of a rectangle, wherein the two accommodating cavities at the opposite corners of the apex can be inserted into the tube, so that one can be The two pipes to be shrunk are punched and compressed.

The feeding assembly is configured to drive the lower mold assembly 10 in a stepwise manner along the interval direction of the upper mold assembly 30, that is, in accordance with the sequence of the respective punching and pressing processes for each of the to-be-shrinkable pipes, and to The assembly 10 is driven below each of the upper mold assemblies 30. A lower die assembly 10 is suspended below the upper mold assembly 30.

As shown in Figures 4 and 5, the feed assembly can include a feed station 21 and a feed fork 22. The feeding table 21 is provided with positioning grooves 211 extending in the spacing direction of the upper mold assembly 30. The lower mold assembly 10 is disposed in the positioning groove 211, so that the feeding table 21 can support the lower mold assembly 10. The feeding fork 22 includes a plurality of fork rods 221, a first fork lever transmission mechanism 222 and a second fork rod transmission mechanism 223 which are arranged at intervals, and the first fork lever transmission mechanism 222 can drive the plurality of fork rods 221 to move left and right in the horizontal direction and Moving up and down in the vertical direction, the second fork lever transmission mechanism 223 can drive the plurality of fork levers 221 to move left and right in the horizontal direction.

Before the punching port is performed, the first fork lever transmission mechanism 222 can drive the plurality of fork levers 221 in the interval direction (horizontal direction) of the upper mold assembly 30 and the transmission direction (vertical direction) of the cylinder cylinder 40, so that the plurality of forks The rods 221 are respectively driven to the lateral sides of the corresponding lower mold assembly 10, at which time one fork rod 221 is located between the two lower mold assemblies 10, and then the second fork rod drive mechanism 223 is spaced along the upper mold assembly 30. The plurality of forks 221 are directionally driven such that the forks 221 are moved to move the corresponding lower die assemblies 10 in the spaced direction of the upper die assembly 30. Based on this mode, the feed fork 22 can drive the lower die assembly 10 from the upper feed position to the feed table 21, and then the lower die assembly 10 is sequentially transferred to each press station for punching and pressing. After the compression port is completed, the lower die assembly 10 is driven from the feed table 21 to the lower feed position.

When the feed assembly drives the lower mold assembly 10 below the upper mold assembly 30, the press cylinder 40 is used to drive the plurality of upper mold assemblies 30 to punch the compressed ports. The plurality of upper mold assemblies 30 are configured to perform multiple punching of the pipe to be shrunk. Since the shape of the shrinkage is different in multiple punching, the cavities of the plurality of upper mold assemblies 30 are different from each other, thereby making the shrinkage to be narrowed. The tubes are progressively formed into a desired constricted shape after being sequentially stamped through a plurality of upper mold assemblies 30. Wherein, if the feeding assembly simultaneously drives the plurality of lower mold assemblies 10 in the interval direction of the upper mold assembly 30, the punch cylinder 40 can drive the plurality of upper mold assemblies 30 while simultaneously awaiting reduction on the plurality of lower mold assemblies 10. The mouth pipe is punched and compressed. Of course, if the feed assembly drives only one lower die assembly 10 along the spacing direction of the upper die assembly 30, the press cylinder 40 only drives one upper die assembly 30 to punch the pipe to be shrunk on the lower die assembly 10. Compressed port.

In the present embodiment, one of the important prerequisites for ensuring the quality of the punching and pressing port is the precise alignment of the cavity of the pipe to be shrunk and the upper die assembly 30. To achieve this precise alignment, the lower mold assembly 10 of the present embodiment may be provided with a plurality of positioning posts 11 and a plurality of positioning holes 12 surrounding the pipe to be shrunk, and the upper die assembly 30 is also provided with corresponding positioning posts. And positioning holes. When a plurality of positioning posts of the upper mold assembly 30 are inserted into the corresponding positioning holes 12, and the plurality of positioning posts 11 of the lower mold assembly 10 are inserted into the positioning holes of the upper mold assembly 30, The tube to be shrunk on the lower mold assembly 10 is accurately aligned with the cavity of the upper mold assembly 30, and the punching port can be punched.

Based on the above, the embodiment only needs to assemble the pipe to the lower die assembly 10, and the feeding assembly can drive the lower die assembly 10 in a stepwise manner according to the punching and pressing process, so that the lower die assembly 10 sequentially stays in the upper die. Below the assembly 30, the upper die assembly 30 is then driven by the stamping cylinder 40 to punch the pipe to be shrunk on the lower die assembly 10, without the need for the worker to repeatedly assemble the pipe to be shrunk onto the lower die assembly 10 All punching and pressing operations can be completed, which can improve the automation of punching and compression ports, improve production efficiency, and save labor and equipment costs. When the tube to be shrunk is a cylindrical tube with a battery core inserted, since the battery core has an outwardly projecting tab B, it is not necessary to correct the tab B before the punching port (for example, deviating) The vertical direction is more than a certain angle) and is crushed when punching the compression port, and since the worker does not insert the battery core into the cylindrical pipe without punching the pipe, the embodiment can be reduced by the multi-station pipe The interposer detection component 50 of the mouth device performs the detection.

As shown in FIG. 6, the interposer detecting assembly 50 can include a detector 51, a picking head 52, and a picking drive mechanism 53. When the feeding assembly drives the lower die assembly 10 to the position where the insert detecting assembly 50 is located, the picking transmission mechanism 53 is used to move the detecting head 52 and the detector 51 toward the lower die assembly 10, and the detecting head 52 is disposed. There is a through hole, and the detector 51 is used to detect whether the pipe to be shrunk is inserted with an insert (for example, the tab B). The detector 51 emits two beams of light parallel to the plane of the through hole, and the two beams intersect and the projection of the intersection point falls within the area where the through hole is located, and is inserted into the pipe to be shrunk in the preset insertion direction. When the insertion member B passes through the through hole of the detecting head 52, the insertion member B can be detected by the light emitted from the detector 51, indicating that the insertion member B is inserted into the pipe to be shrunk and the position of the insertion member B is inserted. It is correct (the ear B is straight), and when the insert B does not pass through the through hole, the light emitted by the detector 51 cannot be detected, indicating that the inserted pipe is not inserted into the pipe. B, or the position of the interposer B is more than a certain angle from the vertical direction (the tab B is not straight), for example, the interposer B is bent by the detecting head 52 or the interposer B is located outside the through hole.

Based on this, in the transmission process of the lower mold assembly 10 in the interval direction of the upper mold assembly 30, the press cylinder 40 detected at the stay position of the lower mold assembly 10 in which the insert B is not inserted is not driven. The die assembly 30 performs a punching port. To achieve the separate punching port, the stamping cylinders 40 are a plurality of independently disposed ones, and each of the stamping cylinders 40 independently drives the corresponding upper die assembly 30.

After the pipe to be shrunk completes the punching port, the embodiment can provide a negative pressure to the pipe on the lower die assembly 10 through the dust collecting assembly 60 of the multi-station pipe shrinking device to complete the pipe of the punching port ( Includes the ear B) for dust removal. As shown in FIGS. 5 and 7, the dust suction assembly 60 may include an air duct 61 and a gas nozzle 62. The air guiding pipe 61 is connected to the air pump, and the air nozzle 62 is connected to the air guiding pipe 61 and directed to the necking position of the pipe to be shrunk which completes the punching port, thereby dusting the pipe and the tab B when the pipe reaches the gas nozzle 62. Of course, the dust suction assembly 60 of the present embodiment can be coupled to a guide rail 63 and can be moved up and down along the guide rail 63 such that the air nozzle 62 is aligned above the pipe and the tab B and is dusted.

After the container 10 is taken out of the accommodating cavity, the clamp 71 is rotated by a predetermined angle, for example, after rotating 90°, the pipe is horizontal, and the tabs B at both ends of the pipe are horizontally placed, and the third cutting mechanism 74 is used. The transmission jig 71 is moved in the horizontal direction to drive the pipe to be retracted clamped by the jig 71 to a predetermined product collection area, and finally, the first unloading transmission mechanism 72 transmits the jig 71 to release the pipe.

On the basis of the foregoing, the multi-station pipe shrinking device of the embodiment may further include a flow converting component for transferring the lower die assembly 10 between the lowering level and the loading level, thereby enabling a plurality of workers to be simultaneously contracted The mouth pipe is assembled to the lower die assembly 10 to improve production efficiency.
