Description

Technical Field

[0001] The utility model belongs to the field of protective shell production equipment, and in particular relates to a protective shell assembly microfiber production line. Background Art

[0002] A protective case is an outer shell that protects mobile phones and other electronic products. Some protective cases need to be fitted with microfiber inside to enhance the cushioning effect of the protective case. The existing production method of assembling microfiber in protective cases is a manual operation method, which requires manual operation to complete the hot pressing, cold pressing, brushing and laser marking of the microfiber inside the protective case in sequence. This manual operation method has problems such as large labor volume, low production efficiency, low yield rate, poor consistency, safety hazards, and exhaust gas that is harmful to the health of workers. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a protective shell assembly microfiber production line, which is characterized by putting the protective shell in a positioning jig, placing it on a loading table, and clamping the positioning jig by a clamping head on a six-axis robotic arm. The production line can perform hot pressing, cold pressing, brushing and laser marking of the microfiber inside the protective shell on the clamped positioning jig in sequence. The entire production process only requires one person to operate, which reduces the workload and improves production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A protective shell assembly microfiber production line comprises a positioning jig, a loading platform, a six-axis robotic arm, a hot pressing component, a cold pressing component and a bristle marking component, wherein the loading platform, the hot pressing component, the cold pressing component and the bristle marking component surround the six-axis robotic arm, the positioning jig is provided with a mounting groove, and the side of the positioning jig is provided with a matching hole; a clamping jaw is rotatably connected to the six-axis robotic arm, the clamping jaw is formed by two groups of clamping components connected in parallel, the clamping component comprises a driving motor and two groups of clamping heads, the output end of the driving motor is connected to the clamping head, the two groups of clamping heads correspond to each other, and the clamping head matches the matching hole.

[0006] The hot pressing assembly includes a hot pressing head, a hot pressing cylinder and a first supporting platform, the positioning jig can be abutted and connected to the first supporting platform, and the hot pressing head abuts against the positioning jig under the drive of the hot pressing cylinder; the cold pressing assembly includes a cold pressing head, a cold pressing cylinder and a second supporting platform, the positioning jig can be abutted and connected to the second supporting platform, and the cold pressing head abuts against the positioning jig under the drive of the cold pressing cylinder; the bristle marking assembly includes a bristle head, a laser marking head and a third supporting platform, the positioning jig can be abutted and connected to the third supporting platform, and the bristle head and the laser marking head point to the third supporting platform respectively.

[0007] The protective shell assembly microfiber production line adopts this structure. There are several groups of receiving slots on the positioning jig. The function of the receiving slots is to place the protective shells. First, multiple protective shells containing microfibers are manually placed in the receiving slots of the positioning jig. At this time, the started six-axis robotic arm drives the clamping claw to move to the position of the positioning jig containing the protective shells. After the two groups of clamping heads are driven away from each other by the pushing motor, the clamping claw moves down to the position of the positioning jig until the clamping head is aligned with the matching hole on the positioning jig. The pushing motor is driven again to make the two groups of clamping heads approach each other until the clamping head is inserted into the matching hole, so that the clamping claw grabs the positioning jig.

[0008] The six-axis robotic arm moves to the side of the hot pressing component, and drives a group of clamping heads to take out the positioning fixture that has completed hot pressing from the hot pressing component. The two groups of clamping heads rotate horizontally 180 degrees, and the six-axis robotic arm drives another group of clamping heads to place the un-hot pressed positioning fixture into the first supporting platform. The six-axis robotic arm withdraws from the area where the hot pressing component is located. The hot pressing head is driven by the hot pressing cylinder to press down and start hot pressing the ultra-fiber to melt the hot melt adhesive on the back of the ultra-fiber and fit the ultra-fiber to the inside of the protective shell.

[0009] The six-axis robotic arm moves to the side of the cold pressing component, and drives a group of clamping heads to take out the cold pressed positioning fixture from the cold pressing component. The two groups of clamping heads rotate horizontally 180 degrees, and the six-axis robotic arm drives another group of clamping heads to place the uncold pressed positioning fixture into the second carrier platform. The six-axis robotic arm withdraws from the area where the cold pressing component is located. The cold head is driven by the cold pressing cylinder to press down and start cold pressing the ultra-fiber to make the hot melt adhesive solidify quickly to prevent the ultra-fiber from deformation and warping.

[0010] The six-axis robot moves to the side of the bristle marking component, drives a group of clamping heads to take out the positioning fixture that has completed the bristle marking from the bristle marking component, and the two groups of clamping heads rotate horizontally 180 degrees. The six-axis robot drives another group of clamping heads to put the positioning fixture that has not been marked with bristles into the third carrier platform. The six-axis robot withdraws from the area where the bristle marking component is located, and the bristle head and light marking head begin to brush and laser mark the microfiber to remove foreign matter on the surface of the microfiber and laser engrave marks.

[0011] The worker puts several protective shells with microfiber into the receiving slot of the positioning jig again. The six-axis robot arm drives a set of clamping heads to put the positioning jig with completed microfiber bristles and laser marking on the loading table, and manually takes out the processed protective shell. The two sets of clamping heads rotate 180 degrees horizontally, and the six-axis robot arm drives another set of clamping heads to take out the unprocessed positioning jig from the loading table, and repeat the operation continuously.

[0012] Furthermore, a limiting column is provided on the loading platform, and a limiting hole is provided on the positioning fixture, and the limiting hole cooperates with the limiting column.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The production line can simultaneously complete the automatic processing of multiple protective shells assembled with ultra-fibers, including hot pressing, cold pressing, brushing and laser marking of the ultra-fiber inside each protective shell. The entire production process only requires one person to operate, reducing the workload and improving production efficiency.

[0015] 2. Compared with manual operation, the hot pressing component can control the hot pressing position, hot pressing temperature and hot pressing pressure of the ultra-fiber inside the protective shell more accurately, thereby improving the hot pressing yield rate; the cold pressing component can control the cold pressing position, cold pressing temperature and cold pressing pressure of the ultra-fiber inside the protective shell more accurately, thereby improving the cold pressing yield rate.

[0016] 3. After the hot pressing component completes the hot pressing of the ultra-fiber inside the protective shell, the six-axis robotic arm immediately transfers the protective shell in the positioning fixture to the cold pressing component for cold pressing, which solves the problem of ultra-fiber deformation and warping caused by long-term placement after manual hot pressing, and improves the flatness of the ultra-fiber bonding.

[0017] 4. The bristle marking component can automatically complete the bristle and laser marking processing, remove foreign matter on the surface of the microfiber, avoid secondary contamination caused by manual work, and the laser marking position is more accurate and the mark is clearer, which improves the yield rate of bristle and laser marking.

[0018] 5. The production line adopts a loop design. At each workstation, after one gripper takes out the processed protective shell, the other gripper immediately puts in the protective shell to be processed, which solves the problem of work-in-progress accumulation in manual operations, reduces the floor space of the production line, shortens the processing cycle, and further improves production efficiency. The production line automatically processes the protective shell assembly microfiber according to the set program, avoiding the problem of missed processing in manual operations, improving the pass rate of good products, and improving the consistency of mass production.

[0019] 6. The hot pressing components, cold pressing components and brush marking components of the production line are far away from the operating workers, eliminating safety hazards in production and benefiting the health of workers. BRIEF DESCRIPTION OF THE DRAWINGS

After the two groups of clamping heads 322 are driven away from each other by the pushing motor 321, the clamping claw 31 moves down to the position of the positioning jig 1 until the clamping head 322 is aligned with the matching hole 12 on the positioning jig 1. The pushing motor 321 is driven again to make the two groups of clamping heads 322 approach each other until the clamping head 322 is inserted into the matching hole 12, so that the clamping claw 31 grabs the positioning jig 1.

[0032] The six-axis robot 3 moves to the side of the hot pressing component 4, and the six-axis robot 3 drives a group of clamping heads 322 to take out the positioning fixture 1 that has completed hot pressing from the hot pressing component 4. The two groups of clamping heads 322 rotate horizontally 180 degrees, and the six-axis robot 3 drives another group of clamping heads 322 to place the un-hot pressed positioning fixture 1 into the first supporting platform 43.
