Description

Technical Field

[0001] The present invention relates to the field of cutting technology, and in particular to a rubber tapping device for lithium battery production. Background Art

[0002] By wrapping the termination tape on the surface of the lithium battery, the lithium battery termination tape can prevent the termination part of the battery cell from directly contacting the external metal parts, avoiding short circuit and electrochemical corrosion. The lithium battery termination tape uses polypropylene insulation material as the base material and is coated with a special acrylic glue resistant to lithium battery electrolyte. Therefore, after the termination tape is wrapped on the surface of the lithium battery, it is necessary to cut the termination tape through a rubber tapping device to facilitate the removal of the residual termination tape on the surface of the lithium battery. Technical inspiration for the rubber tapping device; At present, CN202310241703.2 in the prior art discloses a rubber tapping device for lithium battery production. The invention is provided with a rubber tapping part. After the battery inside the box is glued, the connecting plate is pressed so that the connecting plate is slidably connected to the outer wall of the fixed rod, driving the rubber tapping knife fixedly connected to the bottom to move downward to cut the rubber on both sides of the battery. After the rubber tapping is completed, the damage to the lithium battery is reduced to a certain extent when the workers tap the lithium battery, and the situation of the lithium battery sliding and damaged appearance and then scrapped is reduced during rubber tapping, which improves the quality of the workers' tapping of the lithium battery to a certain extent; by providing an adjustment part, the device can adapt to lithium batteries of various sizes, so that the workers can use the device to tap the lithium battery more conveniently and quickly, and at the same time, the device can be closer to the surface of the lithium battery when tapping the lithium battery, so that the tapping of the lithium battery is more perfect, and the tapping of the lithium battery is improved to a certain extent; Combining the prior art and comparative documents, it is found that the rubber tapping device needs to adjust the limit of the lithium battery through a limit mechanism. Since lithium batteries usually have different models and sizes, the rubber tapping device usually needs to manually adjust the limit of the limit mechanism according to the size of the lithium battery, which results in the rubber tapping device being unable to quickly limit the lithium battery according to the size of the lithium battery; After the rubber tapping device has completed the limited cutting of the lithium battery, the limiting mechanism needs to be dismantled to facilitate the removal of the lithium battery inside the limiting mechanism, which results in the rubber tapping device being unable to quickly remove the limited lithium battery; The present invention can mainly solve the problem that the rubber tapping device cannot quickly limit the lithium battery according to the size of the lithium battery. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a rubber tapping device for lithium battery production to solve the problems described in the above background technology.

[0004] The purpose and effect of the rubber tapping device for lithium battery production of the present invention are achieved by the following specific technical means: a rubber tapping device for lithium battery production, including a cutting table, a displacement table is provided on one side of the upper end of the cutting table, the upper end of the displacement table is rotatably connected to a screw, the end of the screw is swingably connected to a blade, and one end of the blade is hinged to one side of the upper end of the displacement table through a hinge.

[0005] Furthermore, a base is provided on one side of the cutting table close to the blade, a groove is provided on the upper end of the base, and the lithium battery is placed inside the groove.

[0006] Furthermore, the groove of the base is arranged in an arc shape with an arc angle of 180°, and a sliding groove is provided on the inner side of the groove.

[0007] Furthermore, the displacement platform is divided into two groups, a transverse group and a longitudinal group. The inner sides of the two groups are provided with screws, and one end of the screw is provided with a handle.

[0008] Furthermore, the blade is perpendicular to the base, and the blade swings in a vertical direction on one side of the translation platform via a hinge.

[0009] Furthermore, a sliding block is slidably connected to the inner side of the slide groove of the base, a clamping ring is slidably connected to one side of the sliding block, a side ring is embedded in the upper end of the clamping ring, and one end of the side ring away from the clamping ring is embedded in the inner wall of the base groove.

[0010] Furthermore, the sliding block slides on both sides of the base slide groove, the sliding block is matched with the clamping ring, and a storage groove is opened on one side of the sliding block.

[0011] Furthermore, the end of the clamping ring away from the side ring is arranged in an arc shape, the side surface of the clamping ring is arranged in an arc shape, the clamping ring passes through the inner side of the base groove, the clamping ring is at the upper end of the base slide groove, and the clamping ring slides at an arc angle on both sides of the base.

[0012] Furthermore, the side ring is arranged in an arc shape with an arc angle of 180°, and the side ring runs through both sides of the base groove. The side ring is made of a deformable material, such as rubber.

[0013] Furthermore, a through-bearing is passed through the middle of the base slide groove, a rotating ring is rotatably connected to the outer side of the through-bearing, and a lining plate is swingably connected to the side of the rotating ring close to the retaining ring.

[0014] Furthermore, the slide groove of the through-bearing and the base is matched with each other, the rotating rings are arranged at two ends of the outer side of the through-bearing respectively, and the lining plate and the rotating ring are matched with each other.

[0015] Furthermore, the lining plate is arranged in a transverse "T" shape, and one end of the lining plate away from the rotating ring is slidably embedded in the receiving groove of the sliding block.

[0016] Beneficial effects: 1. When the lithium battery is not placed inside the groove of the base, since the groove of the base is arc-shaped, the snap ring can slide downward inside the groove of the base through the sliding block, and the snap rings on both sides of the base are at the lower end of the groove, and the snap rings simultaneously stretch the lower end of the side ring, and at this time the side ring is stretched downward on the inner side of the base; 2. After the lithium battery is placed in the groove of the base, the lithium battery is squeezed to one side of the clamp ring, and the clamp ring can slide from bottom to top through the sliding block. When the clamp ring slides upward, the upper end of the clamp ring is squeezed to the lower end of the side ring. Since the other end of the side ring is embedded in the inner side of the base, the side ring is arched and deformed. By utilizing the deformation of the side ring, the side ring can form an extrusion limit on both sides of the lithium battery, which is convenient for the blade to cut the termination tape on the surface of the lithium battery. In addition, by utilizing the adjustability of the side ring, the rubber tapping device can form a limit fixation on both sides of the lithium battery according to the size of the lithium battery; 3. When the sliding block slides upward through the snap ring, the lining plate is in a stationary state, and the sliding block slides on both sides of the base slide groove. At this time, the lining plate and the through bearing are both inside the slide groove of the base, the lower end of the lithium battery is inside the groove of the base, and the lower end of the lithium battery is at the upper end of the slide groove; 4. When the termination tape on the surface of the lithium battery is cut, the lithium battery is manually taken upward from the inside of the groove of the base. At this time, the lithium battery cannot be continuously squeezed to one side of the clamping ring, and the clamping ring slides downward on the inner side of the base, and the sliding block slides downward synchronously. The sliding block slides to the lower end of the base slot. At this time, the lining plate slides as a whole and is nested in the storage groove of the sliding block, and the sliding block is squeezed to one end of the lining plate. The through-bearing is squeezed by the sliding block, and the through-bearing is in a suspended state. The through-bearing extends to the upper end of the slot of the base. Through the upward movement of the through-bearing, the through-bearing can be squeezed to the lower end of the lithium battery, assisting the lithium battery to be quickly taken out from the upper end of the base, avoiding the situation that the existing rubber tapping device cannot quickly take out the cut lithium battery after the lithium battery is limitedly cut.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

Figure 6 As shown; The translation platform 101 is divided into two groups, namely, a horizontal group and a vertical group. The inner sides of the two groups are provided with a screw rod 102, and one end of the screw rod 102 is provided with a handle; The handle is manually operated to drive the screw 102 to rotate. The screw 102 rotates and moves on the upper end of the translation platform 101. The screw 102 can be squeezed to one side of the blade 103. The blade 103 swings through the hinge, and then the blade 103 can cut the lithium battery termination tape on the upper end of the base 2; The blade 103 is vertically corresponding to the base 2, and the blade 103 is swung vertically on one side of the translation stage 101 through a hinge; Wherein: the lithium battery is placed inside the groove of the base 2. Since the displacement platform 101 is divided into two groups, namely, the horizontal and vertical groups, the inner sides of the two groups are provided with screws 102. The screws 102 in the horizontal direction of the displacement platform 101 can drive the blade 103 to move horizontally. The handle in the vertical direction of the displacement platform 101 is manually operated. The handle drives the screw 102 to rotate. The screw 102 rotates and moves at the upper end of the displacement platform 101. The screw 102 can be squeezed to one side of the blade 103. The blade 103 swings through the hinge, and then the blade 103 can cut the lithium battery termination tape on the upper end of the base 2. Example 2: Refer to the attached manual Figure 3-8 It can be seen that the difference between Example 2 and Example 1 is that a sliding block 202 is slidably connected to the inner side of the slide groove of the base 2, a clamping ring 201 is slidably connected to one side of the sliding block 202, a side ring 203 is inlaid on the upper end of the clamping ring 201, and one end of the side ring 203 away from the clamping ring 201 is inlaid on the inner wall of the groove of the base 2; Among them: a sliding block 202, the sliding block 202 slides on both sides of the sliding groove of the base 2, the sliding block 202 is matched with the clamping ring 201, and a storage groove is opened on one side of the sliding block 202; A storage slot is provided on one side of the sliding block 202. Figure 8 As shown; The snap ring 201, one end of the snap ring 201 away from the side ring 203 is arranged in an arc shape, the side surface of the snap ring 201 is arranged in an arc shape, the snap ring 201 passes through the inner side of the groove of the base 2, the snap ring 201 is at the upper end of the slide groove of the base 2, and the snap ring 201 slides at an arc angle on both sides of the base 2; One end of the clamping ring 201 away from the side ring 203 is arranged in an arc shape. After the lithium battery is placed in the groove of the base 2, the lithium battery can be squeezed to one side of the clamping ring 201, and then the clamping ring 201 can be assisted to slide from bottom to top on both sides of the groove of the base 2 by the extrusion of the lithium battery; Since the groove of the base 2 is arranged in an arc shape, the clamping ring 201 slides at an arc angle on both sides of the base 2. Figure 4 and 5 As shown; The side ring 203 is arranged in an arc shape with an arc angle of 180°. The side ring 203 runs through both sides of the groove of the base 2. The side ring 203 is made of a deformable material, such as rubber; The side ring 203 penetrates both sides of the groove of the base 2. When the clamping ring 201 slides downward inside the groove of the base 2, the clamping ring 201 simultaneously stretches the lower end of the side ring 203. At this time, the side ring 203 is stretched downward on the inner side of the base 2. Figure 4 As shown; Wherein: When the lithium battery is not placed inside the groove of the base 2, since the groove of the base 2 is arranged in an arc shape, the snap ring 201 can slide downward inside the groove of the base 2 through the sliding block 202, and the snap rings 201 on both sides of the base 2 are at the lower end of the groove, and the snap ring 201 simultaneously stretches the lower end of the side ring 203. At this time, the side ring 203 is stretched downward on the inner side of the base 2. Figure 4 As shown; After the lithium battery is placed in the groove of the base 2, the lithium battery is squeezed to one side of the clamping ring 201. The clamping ring 201 can slide from bottom to top through the sliding block 202. When the clamping ring 201 slides upward, the upper end of the clamping ring 201 is squeezed to the lower end of the side ring 203. Since the other end of the side ring 203 is embedded in the inner side of the base 2, the side ring 203 is arched and deformed. By utilizing the deformation of the side ring 203, the side ring 203 can form an extrusion limit on both sides of the lithium battery, which is convenient for the blade 103 to cut the termination tape on the surface of the lithium battery. In addition, by utilizing the adjustability of the side ring 203, the rubber tapping device can form a limit fixation on both sides of the lithium battery according to the size of the lithium battery. Example 3: Refer to the attached manual Figure 6-8 It can be seen that the difference between Example 3 and Example 1-2 is that a through-bearing 3 is passed through the middle of the inner part of the slide groove of the base 2, a rotating ring 301 is rotatably connected to the outer side of the through-bearing 3, and a lining plate 302 is swingably connected to the side of the rotating ring 301 close to the clamping ring 201; Among them: the through-bearing 3 and the rotating ring 301, the through-bearing 3 and the slide groove of the base 2 are matched, the rotating ring 301 is arranged at both ends of the outer side of the through-bearing 3, and the lining plate 302 is matched with the rotating ring 301; The lining plate 302 is arranged in a transverse "T" shape, and one end of the lining plate 302 away from the rotating ring 301 is slidably embedded in the receiving groove of the sliding block 202; When the sliding block 202 is not sliding, the sliding block 202 is at the lower end of the slide groove of the base 2. At this time, the lining plate 302 is integrally slid and nested in the storage groove of the sliding block 202, and the sliding block 202 is pressed to one end of the lining plate 302. Due to the pressing of the sliding block 202, the through-bearing 3 is in a suspended state, and the through-bearing 3 extends to the upper end of the slide groove of the base 2. When the sliding block 202 slides upward through the snap ring 201, the lining plate 302 is in a stationary state, and the sliding block 202 slides on both sides of the slide groove of the base 2. At this time, the lining plate 302 and the through bearing 3 are both inside the slide groove of the base 2, and the lower end of the lithium battery is inside the groove of the base 2, and the lower end of the lithium battery is at the upper end of the slide groove; When the tape on the surface of the lithium battery is cut, the lithium battery is manually taken upward from the groove of the base 2. At this time, the lithium battery cannot be continuously squeezed to one side of the retaining ring 201. The retaining ring 201 slides downward on the inner side of the base 2, and the sliding block 202 slides downward synchronously. The sliding block 202 slides to the lower end of the slide groove of the base 2. At this time, the lining plate 302 is slid and nested in the storage groove of the sliding block 202 as a whole, and the sliding block 202 is squeezed to one end of the lining plate 302. Due to the squeezing generated by the sliding block 202, the through-bearing 3 is in a suspended state, and the through-bearing 3 extends to the upper end of the slide groove of the base 2. Through the upward movement of the through-bearing 3, the through-bearing 3 can be squeezed to the lower end of the lithium battery, assisting the lithium battery to be quickly taken out from the upper end of the base 2, avoiding the situation that the existing rubber tapping device cannot quickly take out the cut lithium battery after the lithium battery is limitedly cut.
