DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1-Figure 5 The assembly line of a polygonal cream bottle shown in the figure is used for assembling polygonal cream bottle products, such as Figure 6 As shown, the polygonal cream bottle product includes two parts: a bottle body 81 and a bottle cap 82. The top of the bottle body 81 is provided with an external thread, and the bottle cap 82 is provided with an internal thread. Before leaving the factory, the bottle cap 82 needs to be threadedly assembled to the bottle body 81. The purpose of the present invention is to apply automation to complete the above operation. A polygonal cream bottle assembly production line includes a first grasping robot 1, a bottle body feeding conveyor belt 2 and a finished product conveyor belt 6. The first grasping robot 1 can rotate 360 ​​degrees and can telescope to grasp the workpiece. On the movement path of the first grasping robot 1, the workpieces are grasped in sequence. A bottle feeding station 11, an assembly station 12 and a finished product output station 13 are provided. A bottle feeding conveyor belt 2 is installed at the bottle feeding station 11. The bottle feeding conveyor belt 2 can convey the bottles 81 one by one. A body cover assembly device 3 is installed at the assembly station 12. The body cover assembly device 3 is used to automatically complete the assembly operation of the polygonal cream bottle product. The body cover assembly device 3 includes a bottle body bracket 31 and a bottle body driving mechanism 32. A single bottle body 81 can be grabbed and placed on the bottle body bracket 31 by a first grabbing robot 1. The side of the body cover assembly device 3 A bottle cap feeding conveyor belt 4 and a second grabbing robot 5 are installed. The bottle cap feeding conveyor belt 4 can convey bottle caps 82 one by one. The second grabbing robot 5 can grab a single bottle cap 82 to the position just above the bottle body 81 of the bottle body bracket 31. A gap is left between the bottle cap 82 and the bottle body 81 below. The bottle cap 82 remains in a grabbed state and is fixed above the bottle body 81 without moving. In this case, the assembly preparation work is done well. The bottle body bracket 31 and the bottle body driving mechanism 32 are connected in transmission, and the bottle body driving mechanism 32 can form a rotating and rising effect of the bottle body 81 Since the bottle cap 82 is stationary, the rotation and rising of the bottle body 81 can make the bottle body 81 gradually threadedly connected to the bottle cap 82, thus completing the automated assembly of the polygonal cream bottle product. The finished product conveyor belt 6 is installed at the finished product output station 13, and the assembled polygonal cream bottle product is grabbed by the first grabbing robot 1 and outputted to the finished product conveyor belt 6. The present invention adopts automated equipment to complete the process from accessory feeding, accessory assembly to finished product output, and has the advantages of high degree of automation and less manual labor. The application of the present invention can meet the needs of enterprises to reduce costs and increase efficiency.

[0030] In the present invention, the assembly of the polygonal cream bottle product is achieved by rotating and rising the bottle body 81. Figure 2 As shown, the present invention designs a bottle body driving mechanism 32 to solve the power problem. The bottle body driving mechanism 32 includes a power box 321 and a rotating driving assembly 323. A boss 322 is fixedly installed on the top of the power box 321. The rotating driving assembly 323 includes a first motor 3231, a transmission pulley 3232 and a rotating platform 3234. The first motor 3231 is installed on the outside of the power box 321. The output end of the first motor 3231 is connected to a main pulley 3232. The transmission pulley 3232 is rotatably installed on the boss 322. The main pulley 3232 and the transmission pulley 3232 are connected by belt transmission. When the first motor 3231 is started, the transmission pulley 3232 can be driven to rotate by the main pulley 3232. The rotating platform 3234 is arranged parallel to the transmission pulley 3232. The rotating platform 3234 is arranged directly above the transmission pulley 3232. Two symmetrically arranged platform column elements 3235 are connected between the driven pulley 3232, and the rotating platform 3234 and the driving pulley 3232 can rotate synchronously through the platform column element 3235. The bottle body bracket 31 includes a crossbeam 311, an I-shaped linkage seat 312 and a bottle body mounting seat 314. The I-shaped linkage seat 312 is rotatably mounted on the crossbeam 311, and the bottle body mounting seat 314 is mounted on the top of the I-shaped linkage seat 312. The bottle body 81 can be matched and mounted on the bottle body mounting seat 314 (the bottle body 81 is a polygon, which is convenient for rotating with the bottle body mounting seat 314 after mounting). The bottom of the I-shaped linkage seat 312 is frictionally connected to the rotating platform 3234. Under the condition of friction transmission, the I-shaped linkage seat 312 can rotate with the rotating platform 3234. That is to say, after the first motor 3231 is started, a rotational motion effect of the bottle body mounting seat 314 and the bottle body 81 can be formed.

[0031] The above content only solves the problem of the rotation of the bottle body 81. The lifting and lowering of the bottle body 81 is achieved by designing a lifting and lowering driving component 324 in the bottle body driving mechanism 32. Figure 2As shown, the lifting drive assembly 324 includes a lifting tube 3241, a screw rod 3242 and a lifting power element 3244. The lifting tube 3241 is erected and fixedly connected to the lower end surface of the rotating platform 3234. The screw rod 3242 is erected and rotatably mounted on the boss 322. The lifting tube 3241 is threadedly connected to the screw rod 3242. The present invention cleverly uses the platform column element 3235 under the rotating platform 3234 to achieve the movement guidance of the rotating platform 3234. The platform column element 3235 includes a fixed column 32351 and a guide column 32352. The fixed column 32351 is fixedly installed on the transmission pulley. 3232, the fixed column 32351 is installed vertically, the guide column 32352 is matched and inserted into the fixed column 32351, the top of the guide column 32352 is connected to the lower end surface of the rotating platform 3234, and the connection relationship between the guide column 32352 and the fixed column 32351 enables the rotating platform 3234 to be guided in the lifting movement. When the screw 3242 rotates, the lifting tube 3241 can drive the rotating platform 3234 to do the lifting movement, and this lifting movement does not conflict with the rotating movement of the rotating platform 3234 (when the rotating drive assembly 323 is not started, it relies solely on the lifting drive The driving assembly 324 can realize the lifting and lowering movement of the rotating platform 3234. When the rotating driving assembly 323 is started, the rotating platform 3234 can be given a rotating movement to realize the rotating lifting movement). In this way, the rotating and ascending movement effect of the bottle body 81 can be formed, and the polygonal cream bottle product can be assembled. The bottom of the screw 3242 passes through the boss 322 and extends into the power box 321. The bottom of the screw 3242 is installed with a first bevel gear 3243. The power box 321 is rotatably installed with a second bevel gear 3245 and a linkage gear 3246. The second bevel gear 3245 and the linkage gear 3246 are rotatably installed. 246 adopts a coaxial connection, the second bevel gear 3245 and the linkage gear 3246 are coaxially installed and can rotate together, the first bevel gear 3243 and the second bevel gear 3245 are meshed with each other, the lifting power element 3244 is installed in the power box 321, the lifting power element 3244 is transmission-connected with the linkage gear 3246, the lifting power element 3244 can drive the linkage gear 3246 to rotate, and then the rotation effect of the screw 3242 is formed through the meshing relationship between the first bevel gear 3243 and the second bevel gear 3245, so as to finally form the effect of the rotating platform 3234 performing a lifting movement.

[0032] like Figure 2 and Figure 3As shown, the lifting power element 3244 includes a second motor 32441 and a power turntable 32442, the power turntable 32442 is connected to the output end of the second motor 32441, a fan gear 32443 is fixedly connected to the central position of the inner side of the power turntable 32442, the fan gear 32443 rotates with the power turntable 32442, a forward rack 32444 is provided on the power turntable 32442, a reverse rack 32445 is provided on the fan gear 32443, a linkage gear 3246 is alternately meshed with the forward rack 32444 and the reverse rack 32445, and when the linkage gear 3246 is meshed with the forward rack 32444, it can form The screw 3242 can rotate forward, and the rotating platform 3234 and the bottle body 81 can move upward. With the rotation effect, the assembly operation of the polygonal cream bottle product can be completed. When the linkage gear 3246 is engaged with the reversal rack 32445, the screw 3242 can be reversed, and the rotating platform 3234 can move downward, so that the bottle body mounting seat 314 moves downward and resets. In the present invention, for the assembly operation of a polygonal cream bottle product, the second motor 32441 only needs to drive the power turntable 32442 to rotate one circle. During one circle, the rotating platform 3234 completes a round of lifting and lowering movement, and the assembly operation of a polygonal cream bottle product is completed.

[0033] like Figure 2 As shown, a first friction disc 32341 is connected to the top of the rotating platform 3234, a second friction disc 3121 is provided at the bottom of the I-shaped linkage seat 312, two columns 313 are vertically installed on the upper plane of the power box 321, and the crossbeam 311 is plugged and connected to the two columns 313. The crossbeam 311 can move vertically up and down, and a first spring 3131 is set on the outside of each column 313. One end of the first spring 3131 is connected to the top of the column 313, and the other end is connected to the crossbeam 311. Under the elastic force of the first spring 3131, the first friction disc 32341 and the second friction disc 3121 maintain a close contact. In the present invention, the crossbeam 3 11 can carry the I-shaped linkage seat 312 to do lifting and lowering movements, but will not affect the rotation of the I-shaped linkage seat 312, so as to meet the rotation and ascending movement of the bottle body 81. The I-shaped linkage seat 312 and the rotating platform 3234 are connected by friction transmission. This design is to solve the problem of over-twisting. After the bottle body 81 and the bottle cap 82 are threaded in place, if the bottle body 81 continues to be twisted hard, it will cause damage to the bottle body 81 or the bottle cap 82. After adopting the friction transmission design, when the bottle body 81 is threaded in place, the I-shaped linkage seat 312 will not be driven to rotate by friction, and the polygonal cream bottle product can be well protected.

[0034] In actual production, it is found that the thread of the bottle body 81 or the bottle cap 82 may be damaged, which will cause the bottle body 81 and the bottle cap 82 to be unable to be threaded together. This situation needs to be discovered and alerted to the workers in time to solve it. Therefore, if Figure 2 and Figure 4 As shown, the present invention adopts elastic connection between the bottle body mounting seat 314 and the top of the I-shaped linkage seat 312, and two plug rods 3141 are vertically connected to the bottom surface of the bottle body mounting seat 314, and the plug rod 3141 is connected to the top of the I-shaped linkage seat 312. A second spring 3142 is sleeved on the outer side of the plug rod 3141, and one end of the second spring 3142 is connected to the bottom surface of the bottle body mounting seat 314, and the other end is connected to the top of the I-shaped linkage seat 312. The second spring 3142 plays the role of elastic support of the bottle body mounting seat 314, and the plug rod 3141 allows the bottle body mounting seat 314 to only move up and down, leaving a gap between the bottom surface of the bottle body mounting seat 314 and the top of the I-shaped linkage seat 312. It is designed that the bottle body mounting seat 314 is a flexible connection. Under the premise of not affecting the rotational movement of the bottle body 81, if the bottle body 81 cannot be screwed in, the bottle body 81 and the bottle body mounting seat 314 will have space to be pushed down. A push-type signal generator 315 is installed on the top of the I-shaped linkage seat 312. The push-type signal generator 315 blocks the downward route of the bottle body mounting seat 314. If the thread is damaged, the bottle body 81 will not be able to be screwed into the bottle cap 82. The bottle body mounting seat 314 continues to descend until it contacts the push-type signal generator 315. At this time, the contact push-type signal generator 315 sends an alarm signal. After the worker finds the signal, he can deal with the faulty accessories in time.

[0035] like Figure 2 As shown, a detection element 7 is installed on the side of the body-cap combination device 3, and the detection element 7 includes a detector bracket 71. A first detection head 72 and a second detection head 73 are installed on the detector bracket 71. A sensing sticker 3111 is attached to the side of the crossbeam 311. The first detection head 72 and the second detection head 73 are installed toward the sensing sticker 3111. The first detection head 72 and the second detection head 73 form position data by detecting the position of the sensing sticker 3111. The first detection head 72 corresponds to the operation moment of the first grasping robot 1 on the bottle body 81, and the first detection head 72 corresponds to the downward position of the crossbeam 311. When the first detection head 72 detects the sensing sticker 3111, the first grasping robot 1 moves to the body-cap combination device. At position 3, the assembled bottle body 81 is picked up and the new bottle body 81 to be assembled is placed. Then the second grasping robot arm 5 grasps the next bottle cap 82 and puts it in place. The second detection head 73 corresponds to the moment when the second grasping robot arm 5 releases its claws. The second detection head 73 corresponds to the upward position of the beam 311. When the second detection head 73 detects the sensing sticker 3111, it proves that the bottle body 81 has been threaded into place and the polygonal cream bottle product has been assembled. At this time, the second grasping robot arm 5 can release its claws, and the assembled polygonal cream bottle product remains on the bottle body mounting seat 314 waiting to go down. When the second grasping robot arm 5 releases its claws, the rotation drive assembly 323 stops working, and the bottle body 81 should stop rotating.

[0036] like Figure 5 As shown, the first grasping robot arm 1 is equipped with two grasping claws 14 arranged in parallel, and the two grasping claws 14 have clear division of labor. One grasping claw 14 is responsible for operating the bottle body 81 to be assembled, and the other grasping claw 14 is responsible for operating the assembled polygonal cream bottle product. At the position of the body cover combination device 3, one grasping claw 14 takes away the assembled polygonal cream bottle product, and then the other grasping claw 14 is responsible for placing the bottle body 81 to be assembled.

[0037] A polygonal cream bottle assembly method is implemented by using a polygonal cream bottle assembly production line, comprising the following steps:

[0038] (a) Bottle bodies 81 are fed into the bottle body feeding conveyor belt 2, and at the same time, bottle caps 82 are fed into the bottle cap feeding conveyor belt 4;

[0039] (b) The first grasping robot 1 grasps a single bottle body 81, and as the first grasping robot 1 moves, the bottle body 81 is placed on the bottle body support 31, and the second grasping robot 5 grasps a single bottle cap 82 and moves it to a position just above the bottle body 81, and the bottle cap 82 remains grasped and motionless;

[0040] (c) Start the bottle driving mechanism 32 to form a rotation and rising effect of the bottle body 81. The bottle body 81 is threadedly connected with the bottle cap 82 during the rotation and rising to form an assembly effect. After the threaded connection is completed, the second gripping robot 5 releases the claws, and the assembled polygonal cream bottle product remains on the bottle body bracket 31 and descends with the bottle body bracket 31;

[0041] (d) The first grasping robot 1 carries the new bottle body 81 to the position of the bottle body support 31 again, and grasps the assembled polygonal cream bottle product through one of the grasping claws 14 of the first grasping robot 1, and the other grasping claw 14 leaves the new bottle body 81 to be assembled. The first grasping robot 1 carries the assembled polygonal cream bottle product to the position of the finished product conveyor belt 6 for output.

[0042] When the above method is repeated in a cycle, the present invention can realize the automatic, continuous and efficient assembly of polygonal cream bottle products. The present invention has a high degree of automation. Under trouble-free conditions, multiple production lines only need a small number of workers to monitor, which greatly reduces the workload and reduces the labor burden of workers.

[0043] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
