Please refer to Fig. 1, Fig. 2 and Fig. 3, which specifically includes the abutment 1, and the center of the top of the abutment 1 is installed with a cell conveying mechanism 2 for transferring the cell from the previous station to the next station in a longitudinal orientation; On the abutment 1 located on both sides of the cell conveying mechanism 2 and from the direction of the feeding end to the discharging end of the cell conveying mechanism 2, installations are installed in order to transfer the cell from the upper tab current collector welding equipment to this base.

Please refer to Fig. 1, Fig. 2, Fig. 3, and Fig. 8. The outer base 1 of the battery turning mechanism 11 is also equipped with a housing delivery line 9. The main function of the housing delivery line 9 is to provide a stable environment for the operation of the battery core The source of the metal shell, the shell conveying line 9 is also installed at the position corresponding to the cell turning mechanism 11, and the shell-entry mechanism 12 is mainly used to transfer the cell turning mechanism 11 to the cell pusher on the shell-entry mechanism 12. into the metal shell to complete the shell-in process of the battery, and the tail end of the shell conveying line 9 is equipped with a discharge mechanism 13 for removing the battery that has been glued and shell-in processed out of the equipment, and the top of the abutment 1 is also A shell feeding mechanism 10 for automatic feeding into the shell conveying line 9 is installed.

Please refer to Fig. 1 and Fig. 3. In order to enable the cell conveying mechanism 2 to smoothly lift and transfer the cells, a sufficient height is reserved between the cell conveying mechanism 2 and the gluing mechanism 8. However, in order to ensure the gluing work It can operate normally. Specifically, a jacking mechanism 14 and a cell rolling drive 15 are respectively installed at the center of the cell conveying mechanism 2 at the position corresponding to the glue application mechanism 8, wherein the cell rolling drive 15 cooperates with the following high-definition visual The inspection camera conducts adhesive inspection on the batteries that have just been glued to determine whether the glue is completed or whether there are defects and defects, and cooperates with the defective product removal component 6 to remove the detected defective batteries.

At present, the transmission mechanism used in the production and processing of battery cells is mostly a translational transmission mechanism combined with grooves and belts. During the transportation process of this kind of transmission mechanism, the battery cells will first rub against the inner wall of the transmission tank, resulting in the cells always being in a non-stationary state , when it reaches the designated position, the position and angle of the current collector on the battery cell are uncertain, and calibration equipment or manual assistance is required for correction, which will increase the cost of cell processing equipment or labor costs, and the cell The non-static transfer during the transfer process will also cause slight scratches on the surface of the cell; in order to solve this problem, we have designed a cell static transfer mechanism 3.

Specifically, please refer to FIG. 4 , FIG. 5 , and FIG. 6 . The cell transport mechanism 2 is composed of a transport drive mechanism 201 and two cell holders 202 ; The inner side of the end, and the two cell holders 202 are equidistantly fixed with double-station cell brackets.

The conveying drive mechanism 201 includes a base 211 , a lifting cylinder 212 and a translation screw assembly 217 mounted on the middle and sides of the base 211 , and a vertical slide plate 218 is installed on the screw slider of the translation screw assembly 217 .

The conveying drive mechanism 201 also includes a cell lifting frame, which is composed of two parallel and horizontally arranged cell supporting plates 215, and the bottoms of the two cell supporting plates 215 are fixedly connected by two connecting plates 216, The top of the battery lifting frame is equidistantly provided with double-station brackets for positioning the battery when lifting the battery. rail sliding connection.

A lifting base 213 is fixed horizontally on the top of the lifting cylinder 212, and a translation slider 214 is fixedly installed on each of the four corners of the top of the lifting base 213. The central position of the bottom of the two cell supporting plates 215 is integrally formed with a translation slide rail. The two cell support plates 215 are slidably matched with the corresponding translation sliders 214 on the top of the lifting base 213 through the translation slide rails. In order to ensure that the cell lifting frame has sufficient displacement space in the horizontal direction, the length of the translation slide rails is The length of the lifting base 213 is 1.5-1.8 times, and the two connecting plates 216 are respectively located at the two ends of the translation slide rail.

The central portion of the lifting base 213 is also reserved with perforations for installing the jacking mechanism 14 and the cell rolling drive 15 .

When the entire cell conveying mechanism 2 is working, the vertical slide plate 218 is first driven by the translation screw assembly 217 to move toward one end of the transfer mechanism 3, and the lifting cylinder 212 shrinks to the shortest during the moving process, so that the cell lifting frame moves from the cell supporting platform The lower sides of the 202 are moved to a predetermined position, and then the lifting cylinder 212 is stretched to lift the cell lifting frame through the lifting base 213. At this time, the cell lifting frame lifts the cell on the cell supporting platform 202. At this time The translation lead screw assembly 217 moves to drive the cell lifting frame to move in translation. When the predetermined stroke is reached, the lifting cylinder 212 retracts, so that the cells on the cell lifting frame fall to the corresponding station, and then the cell lifting frame moves on the translation wire. After returning to the initial position under the driving of the bar assembly 217, the above-mentioned process is repeated, thereby realizing a reciprocating cycle.

Further explanation is needed: due to the cooperation between the cell lifting frame and the vertical slide plate 218, the sliding block and the sliding rail are used, and the sliding cooperation of the sliding rail and the translation slider 214 is usually used between the cell lifting frame and the lifting base 213. The horizontal and vertical axial movements of the conveying drive mechanism 201 are realized without interfering with each other.

As we all know, the length of the battery cells of the same specification is generally the same, and the position of the glue is mainly located on the outside of the battery cell near the first and last ends. The transfer mechanism 3 transfers it to the cell conveying mechanism 2. The initial position of the cell has not been corrected. It is necessary to correct the position of the cell to ensure the accuracy of the glue on both ends of the subsequent cell. In order to achieve the purpose of cell position correction .

The positive and negative electrode current collector detection device 4 is mainly composed of electronic detection probes installed at both ends of the installation wall and the top of the installation arm; the electronic detection probes designed at both ends of the top of the installation arm mainly use laser ranging Sensor, the electronic detection probe located at the negative end of the cell detects the distance between the current collector of the negative electrode of the cell and the electronic detection probe in a horizontal orientation, so as to detect the position of the cell, while the electronic detection probe located at the positive end of the cell is vertical Azimuth detection The distance between the folded ear of the positive electrode current collector and the electronic detection probe forms a complementary detection mechanism for horizontal and vertical azimuths to improve the accuracy of cell position detection and provide accurate parameters for subsequent cell position calibration.

Compared with the push-up method adopted by the conveying mechanism combined with the traditional trough-belt when transferring the material on it, the static translation conveying is not suitable for the traditional push-push method due to the difference between the conveying mechanism and the trough-belt conveying. The upper material is transferred by means of top, so it is necessary to use a transfer device that can cooperate with static translation transmission to meet the rejection of defective products and the static transfer of batteries between different devices.

Specifically, please refer to Fig. 1, Fig. 12, defective product rejecting assembly 6 comprises conveying mechanism and collection box; wherein conveying mechanism and transfer mechanism 3 structures are the same; A translation cylinder drive unit 302 is horizontally installed on the top; a lift cylinder 303 is vertically installed on the sliding block of the translation cylinder drive unit 302;

Two sets of high-definition visual inspection cameras are installed at the bottom of the side of the installation frame 801 close to the defective product removal component 6, and the high-definition visual The main function of the detection camera is to cooperate with the battery cell rolling drive 15 to carry out glue inspection on the glued battery cells, to provide accurate signals for the subsequent removal of defective products, and to prevent defective products from entering the market.

When the glue application mechanism 8 implements glue application, the jacking mechanism 14 first needs to lift up the batteries on it, and make it closely fit with the glue application pressure roller 803, so that the adhesive tape and the surface of the batteries are attached, and then the glue is applied.
