Description

TECHNICAL FIELD

[0001] The utility model relates to insulator processing equipment technical field especially relates to a hexagonal polishing equipment of insulator. BACKGROUND

[0002] The battery pack is the shell of assembling battery monomer into a battery pack, it protects and supports battery monomer, and provides the electrical connection and distribution of battery pack inside. The insulator needs to be arranged in the battery pack, and the main role of the insulator in the battery pack is to insulate between the electrodes and the shell, to ensure the normal work of the battery.

[0003] Most of the existing insulators are produced by injection molding, but due to improper pressure setting of injection molding machine or insufficient mold manufacturing precision, burrs may be generated on the edge of the product, which will increase the electric field intensity on the surface of the insulator, resulting in discharge phenomenon under high pressure environment, thereby affecting the performance of the insulator. Therefore, it is necessary to polish the outer edge of the insulator.

[0004] The shape of the insulator is various, but most of the insulators used in the battery pack are hexagonal. The hexagonal insulator has excellent insulation performance, which can effectively isolate the electrodes and the shell inside the battery pack, prevent current leakage and short circuit, and ensure the safety and stability of the battery pack, which helps to prolong the service life of the battery.

[0005] And the hexagonal insulator has multiple edges, and it is more complex to polish it than the cylindrical insulator. In the polishing process, the existing technology adopts polishing assembly to polish the six edges of the insulator, and the polishing assembly can only move horizontally in the polishing process. The insulator polished by this method still has residual burrs at the edge and corner, which will affect the performance of the insulator, so manual inspection and treatment of the polished insulator are needed, which is low in processing and production efficiency. SUMMARY

[0006] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide a hexagonal polishing equipment for insulator, which can not only polish the burrs on the edge of the hexagonal insulator, but also finely process the residual burrs on the edge and corner after edge polishing, so as to improve the product quality and production efficiency.

[0007] To solve the above technical problems, the utility model provides a hexagonal polishing equipment for insulator, which adopts the following technical scheme:

[0008] The utility model provides an insulator outer hexagon polishing equipment, including polishing mechanism, workpiece turning mechanism and workpiece transportation mechanism, and polishing mechanism and workpiece turning mechanism are fixedly arranged outside workpiece transportation mechanism, and polishing mechanism includes edge polishing mechanism and corner processing mechanism, and corner processing mechanism includes lifting device and first polishing piece, and first polishing piece includes driving part and polishing head, and driving part and polishing head fixedly connect, and polishing head rotates under the drive of driving part, and polishing head includes fixed rod and two L type polishing pieces, and fixed rod is fixedly connected with driving part, and two L type polishing pieces are symmetrically arranged on fixed rod.

[0009] Adopt this structure, through the joint action of edge polishing mechanism and corner processing mechanism, the equipment can comprehensively and accurately process the outer surface of hexagonal insulator, especially the design of corner processing mechanism can carry out more meticulous polishing treatment to the burr remaining on the insulator corner after the polishing of edge polishing mechanism, to ensure that the polished insulator meets the use standard. Meanwhile, driving part can adopt driving motor and the like, and the design that driving part drives the rotation of polishing head makes the polishing process more flexible, and the L type polishing piece symmetrically arranged on polishing head can well adapt to the complex shape of hexagonal insulator during rotation, to ensure that all areas needing polishing can be covered during the polishing process. The setting of workpiece turning mechanism and workpiece transportation mechanism makes the insulator automatically turn and transport during polishing, without frequent manual movement and adjustment, thereby simplifying the work process and improving the processing efficiency.

[0010] Further, the edge polishing mechanism includes first edge polishing mechanism, second edge polishing mechanism and third edge polishing mechanism, and the first edge polishing mechanism includes pushing device, second polishing piece and third polishing piece, and the third polishing piece is same in structure with the second polishing piece, and the second polishing piece includes driving device and polishing grinding wheel installed at the lower part of driving device, and the second polishing piece and third polishing piece are both installed on pushing device and arranged horizontally in front and back. The horizontal front and back arrangement of two polishing pieces in one edge polishing mechanism can simultaneously polish two edges of hexagonal insulator, and the arrangement of three same edge polishing mechanisms in cooperation with workpiece turning and transportation mechanism can sequentially polish the edges of insulator, which makes the equipment simultaneously process multiple insulators during operation, thereby greatly improving the production efficiency. Meanwhile, by changing the number of polishing pieces in edge polishing mechanism and single edge polishing mechanism, the production needs of polygonal insulators with different edge numbers can be met, which is beneficial to saving production cost.

[0011] Further, the workpiece conveying mechanism comprises a rotating disc and a plurality of fixed clamps, which are evenly spaced along the circumference of the rotating disc. The design of the rotating disc allows the insulator to be quickly transported from one work station to the next by rotating, reducing the waiting time of the insulator between different processes. The design of the fixed clamp can ensure the stability of the insulator during transportation, reducing damage or processing errors caused by shaking or tilting.

[0012] As a preferred embodiment, the fixed clamp comprises a horizontal push cylinder, a fixed seat and a clamping piece. The horizontal push cylinder is fixedly installed below the rotating disc, the clamping piece is fixedly connected with the piston rod of the horizontal push cylinder, and the fixed seat is fixedly installed on the edge of the rotating disc. The rotating disc is provided with a slot extending to the fixed seat, and the clamping piece is in sliding fit with the slot. The clamping piece moves stably in the horizontal direction by the horizontal push cylinder. This allows the clamping piece to slide in the slot and cooperate with the fixed seat to achieve clamping effect when the insulator needs to be fixed. When the insulator needs to be released, the piston rod of the horizontal push cylinder retracts to drive the clamping piece to move to quickly release the insulator. This design allows the fixed clamp to adapt to insulators of different sizes, enhancing the versatility and flexibility of the clamp.

[0013] As a preferred embodiment, the workpiece turning mechanism comprises a first workpiece turning mechanism and a second workpiece turning mechanism which are structurally identical. The first workpiece turning mechanism comprises a clamping piece, a first rotary cylinder and a lifting assembly. The clamping piece is fixedly connected with the first rotary cylinder, and the first rotary cylinder is fixedly arranged on the lifting assembly. As a process after the first edge polishing mechanism and the second edge polishing mechanism finish polishing, the first workpiece turning mechanism and the second workpiece turning mechanism both play a role in turning the insulator. The turned insulator can continue to polish the unpolished edge after reaching the next edge polishing mechanism, thereby completing the polishing of all edges of the insulator.

[0014] As a preferred embodiment, the clamping piece comprises a fixed piece and a negative pressure suction head. The negative pressure suction head is fixedly installed at the bottom of the fixed piece, and the fixed piece is fixedly connected with the first rotary cylinder. The negative pressure suction head is fixedly installed at the bottom of the fixed piece, and the fixed connection of the fixed piece with the first rotary cylinder allows the clamping piece to maintain overall stability and rigidity when rotating, avoiding shaking or deviation caused by rotation and improving the accuracy of clamping. At the same time, since the negative pressure suction head adopts a non-contact clamping method, it avoids damage to the workpiece caused by mechanical clamping, improving the production quality.

[0015] As preferred, the blanking mechanism is further included, which comprises a lifting cylinder, a second rotary cylinder and two blanking heads, the second rotary cylinder is fixedly arranged at the top of the lifting cylinder, and the two blanking heads are respectively installed at the two ends of the second rotary cylinder, and the blanking head is the same in structure as the clamping piece. The blanking mechanism can realize accurate positioning and movement of the blanking head through the cooperation of the lifting cylinder and the second rotary cylinder, and the deviation of the workpiece in the blanking process is reduced. Since the blanking head is the same in structure as the clamping piece, they have the same clamping capacity and accuracy, so that the workpiece can be stably clamped and released in each process. The two blanking heads are respectively installed at the two ends of the second rotary cylinder, so that the blanking mechanism can flexibly adjust the position of blanking according to production needs to adapt to different requirements.

[0016] As preferred, the first edge polishing mechanism, the first workpiece turning mechanism, the second edge polishing mechanism, the second workpiece turning mechanism, the third edge polishing mechanism, the corner processing mechanism and the blanking mechanism are sequentially and circumferentially spaced apart along the workpiece conveying mechanism. Through the sequentially arranged mechanisms, the insulator can sequentially pass through each processing link under the driving of the workpiece conveying mechanism, and realizes flow production. Since each mechanism is circumferentially spaced apart, the workpiece can immediately enter the next mechanism for processing after the processing of one mechanism is completed, the waiting time of the workpiece is reduced, and the overall production efficiency is improved.

[0017] In summary, the insulator outer hexagonal polishing device polishes and conveys the insulator in an automatic manner, can sequentially polish the edges of the hexagonal insulator, and can further polish and process the burrs remaining on the edges after the edge polishing is completed, so as to produce the insulator meeting the use standard, thereby avoiding the problem of manual secondary inspection and polishing, and improving the production efficiency.

DETAILED DESCRIPTION

[0027] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is combined with the drawing and example, and the utility model is further detailed.

[0029] With this structure, through the joint action of the edge polishing mechanism 3 and the corner processing mechanism 4, the device can comprehensively and accurately process the outer surface of the hexagonal insulator, especially the design of the corner processing mechanism 4 can polish the burrs left on the corners of the insulator after polishing by the edge polishing mechanism 3, to ensure that the polished insulator meets the use standard. At the same time, the driving member 421 can use existing products such as driving motors, and the design of the driving member 421 driving the polishing head 422 to rotate makes the polishing process more flexible, and the L-shaped polishing member 424 symmetrically arranged on the polishing head 422 can well adapt to the complex shape of the hexagonal insulator during rotation, ensuring that all areas that need to be polished can be covered during polishing. The arrangement of the workpiece turning mechanism 1 and the workpiece conveying mechanism 2 enables the insulator to automatically turn and transport during polishing, without the need for frequent manual movement and adjustment, thereby simplifying the work process and improving the processing efficiency.

[0030] Further, as shown in Figure 1 and Figure 3 , the edge polishing mechanism 3 includes a first edge polishing mechanism 31, a second edge polishing mechanism 32 and a third edge polishing mechanism 33 which are structurally identical. The first edge polishing mechanism 31 includes a pushing device 311, a second polishing member 312 and a third polishing member 313 which are structurally identical to the second polishing member 312. The second polishing member 312 includes a driving device 314 and a polishing wheel 315 mounted on the lower part of the driving device 314. The second polishing member 312 and the third polishing member 313 are both mounted on the pushing device 311 and arranged horizontally in front and back. The arrangement of two polishing members horizontally in front and back in one edge polishing mechanism 3 can simultaneously polish two edges of the hexagonal insulator, and the arrangement of three identical edge polishing mechanisms 3 in cooperation with the workpiece turning and conveying mechanism can sequentially polish the edges of the insulator. This enables the device to process multiple insulators simultaneously during operation, thereby greatly improving production efficiency. At the same time, by changing the number of polishing members in the edge polishing mechanism 3 and the individual edge polishing mechanism, it can adapt to the production needs of polygonal insulators with different number of edges, which is beneficial to saving production cost.

[0031] Further, as shown in Figure 4 , the workpiece conveying mechanism 2 includes a turntable 21 and a plurality of fixed clamps 22, which are uniformly and circumferentially spaced along the edge of the turntable 21. The design of the turntable 21 enables the insulator to be quickly transported from one work station to the next work station by rotating, reducing the waiting time of the insulator between different processes. The design of the fixed clamp 22 can ensure that the insulator remains stable during transportation, reducing damage or processing errors caused by shaking or tilting.

[0032] As a preferred embodiment, as shown in Figure 4 and Figure 5As shown, the fixing clamp 22 includes a horizontal push cylinder 221, a fixing seat 222 and a clamping piece 223, the horizontal push cylinder 221 is fixedly installed below the rotary disc 21, the clamping piece 223 is fixedly connected with the piston rod of the horizontal push cylinder 221, the fixing seat 222 is fixedly installed at the edge of the rotary disc 21, the rotary disc 21 is provided with a slot 211 extending to the fixing seat 222, and the clamping piece 223 is in sliding fit with the slot 211. The clamping piece 223 moves stably in the horizontal direction through the horizontal push cylinder 221. This makes the clamping piece 223 slide in the slot 211 and cooperate with the fixing seat 222 to achieve the clamping effect when the insulator needs to be fixed, and the piston rod of the horizontal push cylinder 221 retracts to drive the clamping piece 223 to move to achieve the quick release of the insulator when the insulator needs to be released. This design makes the fixing clamp 22 adapt to insulators of different sizes, and enhances the universality and flexibility of the clamp.

As a process after the first edge polishing mechanism 31 and the second edge polishing mechanism 32 complete polishing, the workpiece turning mechanism 11 and the second turning mechanism both play a role in turning the insulator, and the turned insulator can continue to polish the unpolished edge after reaching the next edge polishing mechanism, thereby completing the polishing of each edge of the insulator.

[0034] As preferred, as shown in Figure 6 The clamping piece 111 includes a fixing piece 1111 and a negative pressure suction head 1112, the negative pressure suction head 1112 is fixedly installed at the bottom of the fixing piece 1111, and the fixing piece 1111 is fixedly connected with the first rotary air cylinder 112.

At the same time, since the negative pressure suction head 1112 adopts a non-contact clamping mode, damage to the workpiece caused by mechanical clamping is avoided, and the production quality is improved.

The blanking mechanism 5 can realize accurate positioning and movement of the blanking head 53 through the cooperation of the lifting cylinder 51 and the second rotary cylinder 52, thereby reducing the deviation of the workpiece during blanking. Since the blanking head 53 has the same structure as the clamping piece 111, they have the same clamping capacity and accuracy, thereby ensuring that the workpiece can be stably clamped and released in each process. The two blanking heads 53 are respectively installed at the two ends of the second rotary cylinder 52, so that the blanking mechanism 5 can flexibly adjust the position of blanking according to production needs to adapt to different requirements.

Thus, the problem of manual secondary inspection and polishing is avoided, and the production efficiency is improved.
