Description

A plastic ultrasonic hot melt auxiliary device Technical Field

[0001] This invention relates to the technical field of lithium battery accessories, and specifically to an ultrasonic hot-melt auxiliary device for lower plastic. Background Technology

[0002] Our company's business scope includes battery manufacturing, specifically lithium battery top cover assemblies. This product consists of two parts: a lower plastic sheet and a top cover plate. Ultrasonic heat fusion is used to melt the positioning posts on the lower plastic sheet into the positioning holes on the top cover plate, thereby fixing the lower plastic sheet to the top cover plate.

[0003] Currently, when workers sequentially place the top cover and lower plastic parts onto the fixture, the lack of an anti-reverse placement structure makes it easy for them to be placed backwards. If placed backwards and connected together, it results in defective top cover components, increasing costs for the company. Furthermore, the assembled top cover and lower plastic parts require workers to remove them from the fixture and then sequentially place them back onto it, contributing to lower production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic hot-melt auxiliary device for plastics to solve the above-mentioned defects caused by the prior art.

[0005] An auxiliary device for ultrasonic hot-melting of plastic includes a part inspection mechanism, a part changing mechanism, a part unloading mechanism, and a part fixing mechanism, wherein...

[0006] The inspection mechanism includes photoelectric sensor one and photoelectric sensor two;

[0007] The component changing mechanism is provided in pairs and symmetrically arranged on the inspection mechanism. The component changing mechanism includes a motor and a crank. The motor drives the crank to rotate forward and backward, thereby realizing the position change between the connected and unconnected lower plastic and top cover pieces. The photoelectric sensor 2 is used to detect whether the unconnected lower plastic and top cover pieces are properly placed.

[0008] The unloading mechanism is provided in two pairs and is correspondingly set on each part changing mechanism. The unloading mechanism includes a cylinder, which drives the fixed part mechanism to flip downward and unload the connected lower plastic and top cover piece.

[0009] The positioning mechanism has two pairs and is correspondingly set on each unloading mechanism. The positioning mechanism includes a positioning plate, a clamping plate and a second cylinder. The top cover is positioned by the positioning groove on the positioning plate, and the second cylinder drives the clamping plate to clamp the lower plastic above the top cover. The photoelectric sensor detects whether the top cover and the lower plastic are placed in reverse.

[0010] Preferably, the inspection mechanism further includes a horizontal mounting plate and a vertical mounting plate. The first photoelectric sensor is provided in pairs and is symmetrically distributed from left to right. The first photoelectric sensor is vertically upward and connected to the upper side of the horizontal mounting plate through a "C"-shaped sensor bracket. The vertical mounting plate has an "I"-shaped structure and is centrally mounted on the upper side of the horizontal mounting plate. The vertical mounting plate has an eccentric mounting opening and a through hole above the mounting opening. The second photoelectric sensor is vertically upward and connected to the mounting opening through a sensor bracket. The second photoelectric sensor is coaxially located directly below the through hole.

[0011] Preferably, the component replacement mechanism further includes a motor plate, the motor is horizontally mounted on the upper side of the cross plate via the motor plate, the output end of the motor is keyed to a crank, and a linkage column is vertically connected to the overhang end of the crank. Two pairs of hinge seats are connected to the side of the motor plate, and a hinge bar is hinged to the hinge seat. All the hinge bars are hinged together to an inverted "T"-shaped linkage bar. A linkage groove is provided in the center of the linkage bar, and the linkage column is slidably disposed in the linkage groove.

[0012] Preferably, the unloading mechanism further includes a cylinder plate, which is an inverted "T" shaped structure and connected to the upper end of a pair of hinge bars. The cylinder is horizontally inward and installed in the middle of the cylinder plate. The piston rod end of the cylinder is connected to a hinge seat, and an "L" shaped hinge bar is hinged to the hinge seat. The top end of the cylinder plate is connected to a hinge seat, and an "I" shaped hinge bar is hinged to the hinge seat. The other end of the hinge bar is hinged to the other end of the hinge bar.

[0013] Preferably, the positioning mechanism further includes a cylinder plate two. The positioning plate is horizontally installed on the upper side of the hinge bar two. The upper side of the positioning plate has a rectangular positioning groove near the inside, and a circular clearance groove is provided at the bottom of the positioning groove. The upper side of the positioning plate has an "I"-shaped sliding groove near the outside, and an "I"-shaped sliding block is slidably connected in the sliding groove. The clamping plate is horizontally connected to the upper side of the sliding block, and a rectangular clamping groove is provided on the clamping plate near the inside. The cylinder plate two has a "C"-shaped structure and is horizontally connected to the outer end of the positioning plate. The cylinder two is horizontally connected to the middle of the cylinder plate two, and the piston rod end of the cylinder two is connected to the sliding block.

[0014] Preferably, the horizontal mounting plate has rectangular unloading ports symmetrically arranged on the left and right sides.

[0015] Preferably, a compression spring is horizontally arranged inside the sliding groove.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Automatic workpiece clamping. The top cover plate is positioned by the positioning groove on the positioning plate. Then, the piston rod of cylinder two extends and drives the clamping plate to move inward, clamping the lower plastic piece above the top cover plate. At the same time, photoelectric sensor one can detect whether the top cover plate and the lower plastic piece are placed in reverse.

[0018] 2. Automatic workpiece exchange. The motor drives the crank to rotate in both directions, and simultaneously drives the two pairs of hinge bars to swing left and right, and simultaneously drives the two pairs of fixed parts mechanisms to jump left and right, thereby realizing the position change between the connected and unconnected lower plastic and top cover pieces. At the same time, photoelectric sensor 2 can be used to detect whether the unconnected lower plastic and top cover pieces are properly placed.

[0019] 3. Automatic workpiece unloading. The piston rod of cylinder one retracts and drives hinge bar two downward and outward by 90 degrees, which in turn drives the fixed part mechanism downward and outward by 90 degrees, thus performing the workpiece unloading action.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] As shown in Figures 1 to 7, a plastic ultrasonic hot-melt auxiliary device includes a part inspection mechanism 10, a part changing mechanism 20, a part unloading mechanism 30, and a part fixing mechanism 40.

[0036] The inspection mechanism 10 includes a photoelectric sensor 103 and a photoelectric sensor 105.

[0037] The component changing mechanism 20 is provided in pairs and symmetrically arranged on the inspection mechanism 10. The component changing mechanism 20 includes a motor 202 and a crank 203. The motor 202 drives the crank 203 to rotate forward and backward, thereby realizing the position change between the connected and unconnected lower plastic 50 and top cover plate 60. The photoelectric sensor 105 is used to detect whether the unconnected lower plastic 50 and top cover plate 60 are properly placed.

[0038] The unloading mechanism 30 is provided in two pairs and is correspondingly arranged on each part changing mechanism 20. The unloading mechanism 30 includes a cylinder 302, which drives the fixed part mechanism 40 to flip downward and unload the connected lower plastic 50 and top cover 60.

[0039] The fixing mechanism 40 has two pairs and is correspondingly arranged on each unloading mechanism 30. The fixing mechanism 40 includes a positioning plate 401, a clamping plate 403 and a second cylinder 405. The top cover plate 60 is positioned by the positioning groove 401a on the positioning plate 401. Then, the second cylinder 405 drives the clamping plate 403 to clamp the lower plastic 50 above the top cover plate 60. The photoelectric sensor 103 is used to detect whether the top cover plate 60 and the lower plastic 50 are placed in reverse.

[0040] In this embodiment, the inspection mechanism 10 further includes a horizontal mounting plate 101 and a vertical mounting plate 102. A pair of photoelectric sensors 103 are provided and symmetrically distributed from left to right. The photoelectric sensors 103 are vertically upward and connected to the upper side of the horizontal mounting plate 101 through a "C"-shaped sensor bracket 104. The vertical mounting plate 102 has an "I"-shaped structure and is centrally mounted on the upper side of the horizontal mounting plate 101. The vertical mounting plate 102 has an eccentric mounting opening 102a and a through hole 102b above the mounting opening 102a. The photoelectric sensor 105 is vertically upward and connected to the mounting opening 102a through a sensor bracket 106. The photoelectric sensor 105 is coaxially located directly below the through hole 102b.

[0041] In this embodiment, the component replacement mechanism 20 further includes a motor plate 201. The motor 202 is horizontally mounted on the upper side of the horizontal plate 101 via the motor plate 201. The output end of the motor 202 is keyed to a crank 203, and a linkage column 204 is vertically connected to the overhanging end of the crank 203. Two pairs of hinge seats 205 are connected to the side of the motor plate 201, and hinge bars 206 are hinged to the hinge seats 205. All hinge bars 206 are hinged together to an inverted "T"-shaped linkage bar 207. A linkage groove 207a is provided in the center of the linkage bar 207, and the linkage column 204 is slidably disposed in the linkage groove 207a. The motor 202 drives the crank 203 to rotate forward and backward, and simultaneously drives the two pairs of hinge bars 206 to swing left and right, and simultaneously drives the two pairs of fixed component mechanisms 40 to jump left and right, thereby realizing the position change between the connected and unconnected lower plastic 50 and top cover plate 60.

[0042] In this embodiment, the unloading mechanism 30 further includes a cylinder plate 301, which has an inverted "T" shape and is connected to the upper end of a pair of hinge bars 206. A cylinder 302 is horizontally inwardly positioned and installed in the middle of the cylinder plate 301. The piston rod of the cylinder 302 is connected to a hinge seat 303, and an "L"-shaped hinge bar 304 is hinged to the hinge seat 303. The top of the cylinder plate 301 is connected to a hinge seat 305, and an "I"-shaped hinge bar 306 is hinged to the hinge seat 305. The other end of the hinge bar 304 is hinged to the other end of the hinge bar 306. The piston rod of the cylinder 302 retracts, causing the hinge bar 304 to rotate downwards and outwards by 90 degrees, simultaneously causing the fixing mechanism 40 to rotate downwards and outwards by 90 degrees, thus performing the unloading action.

[0043] In this embodiment, the positioning mechanism 40 further includes a cylinder plate 404. The positioning plate 401 is horizontally mounted on the upper side of the hinge bar 304. The upper side of the positioning plate 401 has a rectangular positioning groove 401a located inward, and a circular clearance groove 401b is provided at the bottom of the positioning groove 401a. The upper side of the positioning plate 401 has an "I"-shaped sliding groove 401c located outward, and an "I"-shaped sliding block 402 is slidably connected in the sliding groove 401c. The clamping plate 403 is horizontally connected to the upper side of the sliding block 402, and a rectangular clamping groove 403a is provided inward on the clamping plate 403. The cylinder plate 404 has a "C"-shaped structure and is horizontally connected to the outer end of the positioning plate 401. The cylinder 405 is horizontally connected inward to the middle of the cylinder plate 404, and the piston rod end of the cylinder 405 is connected to the sliding block 402. The top cover plate 60 is positioned by the positioning groove 401a on the positioning plate 401. Then, the piston rod of the second cylinder 405 extends and drives the clamping plate 403 to move inward, clamping the lower plastic 50 above the top cover plate 60. The photoelectric sensor 103 can be used to detect whether the top cover plate 60 and the lower plastic 50 are placed in reverse.

[0044] In this embodiment, rectangular unloading ports 101a are symmetrically provided on the horizontal mounting plate 101. After the connected lower plastic 50 and top cover plate 60 are removed, they can be transferred away through the unloading ports 101a to avoid them accumulating on top of the horizontal mounting plate 101.

[0045] In this embodiment, a compression spring 406 is horizontally arranged inside the sliding groove 401c. The compression spring 406 helps the cylinder 405 drive the clamping plate 403 to move outward and quickly separate from the end of the lower plastic 50.

[0046] The working principle of this ultrasonic hot-melt auxiliary device for plastics includes the following steps:

[0047] Step 1: The motor 202 drives the crank 203 to rotate counterclockwise to the preset left limit position, and simultaneously drives the front and rear rows of hinge bars 206 to deflect to the left, and simultaneously drives the pair of fixed parts mechanism 40 on the left to be suspended directly above the photoelectric sensor 103 on the left, while the pair of fixed parts mechanism 40 on the right is placed on the upper surface of the vertical plate 102 in the middle.

[0048] Step 2: Place the top cover plate 60 upside down into the positioning groove 401a on the pair of positioning plates 401 on the left side, and then place the lower plastic 50 upside down on top of the top cover plate 60, so that the positioning pins 501 on the lower plastic 50 are inserted into the positioning holes 60a on the top cover plate 60. At the same time, use photoelectric sensor 103 to detect whether the top cover plate 60 and the lower plastic 50 are correctly placed. If they are incorrectly placed, prompt manual intervention. If they are correctly placed, use the pair of cylinders 405 on the left side to drive the corresponding clamping plates 403 to move towards each other and clamp them at the front and rear ends of the lower plastic 50.

[0049] Step 3: The motor 202 drives the crank 203 to rotate clockwise to the preset upper limit position, and simultaneously drives the front and rear rows of hinge bars 206 to move vertically upward, and simultaneously drives the pair of fixed parts mechanisms 40 on the left to be suspended directly above the unloading port 101a on the left, while the pair of fixed parts mechanisms 40 on the right are suspended directly above the unloading port 101a on the right. Then, the pair of cylinders 405 on the right drives the corresponding clamping plates 403 to move in the opposite direction. Next, the pair of cylinders 302 on the right drives the corresponding fixed parts mechanism 40 to rotate downward and outward by 90 degrees to perform the unloading action. After that, the pair of cylinders 302 on the right drives the corresponding fixed parts mechanism 40 to rotate upward and inward by 90 degrees.

[0050] Step 4: Drive the crank 203 clockwise to the preset right limit position through the motor 202, and simultaneously drive the hinge bars 206 in the front and rear rows to deflect to the right, and simultaneously drive the pair of fixing mechanisms 40 on the left to be placed on the upper surface of the vertical plate 102 in the middle. Use photoelectric sensor 105 to detect whether the lower plastic 50 and the top cover 60 are in place. The pair of fixing mechanisms 40 on the right are suspended directly above the photoelectric sensor 103 on the right. Then, according to the content of step 2, fix the top cover 60 and the lower plastic 50 on the pair of fixing mechanisms 40 on the right.

[0051] Step 5: The positioning post 501 on the lower plastic 50, which is placed in place, is melted into the positioning hole 60a on the top cover plate 60 by the ultrasonic pressing block 70 on the ultrasonic hot melt machine.

[0052] Step 6: The motor 202 drives the crank 203 to rotate counterclockwise to the preset upper limit position, and simultaneously drives the front and rear rows of hinge bars 206 to move vertically upward, and simultaneously drives the pair of fixed parts mechanism 40 on the left to be suspended directly above the left unloading port 101a, while the pair of fixed parts mechanism 40 on the right is suspended directly above the right unloading port 101a. Then, the pair of cylinders 405 on the left drives the corresponding clamping plates 403 to move in the opposite direction and away from the front and rear ends of the lower plastic 50. Next, the pair of cylinders 302 on the left drives the corresponding fixed parts mechanism 40 to rotate downward and outward by 90 degrees, and the connected lower plastic 50 and top cover plate 60 are removed and transferred through the unloading port 101a. After that, the pair of cylinders 302 on the left drives the corresponding fixed parts mechanism 40 to rotate upward and inward by 90 degrees.

[0053] Step 7: The positioning post 501 on the lower plastic 50, which is placed in place, is melted into the positioning hole 60a on the top cover plate 60 by the ultrasonic pressing block 70 on the ultrasonic hot melt machine.

[0054] Step 8: Repeat steps 1 to 7.

[0055] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
